8 Claims.

My invention relates in general to paper burster toys and more in particular to a cane with mechanism for bursting paper with an explosive noise. The present invention is more particularly an improvement over the structure of one of my earlier patents-No. 1,004,043, issued September 26, 1911.

An object of the present invention is to provide an improved simplified paper burster embodied in a cane having an elongated handle, and paper feeding and bursting mechanism operated by exerting downward pressure on the handle while holding such mechanism against a rigid surface such as the floor, sidewalk, or the like.

A further object of my invention is the provision of a device of this character having relatively few elements, substantially all of which are stamped out and of such configuration that may be quickly and easily manufactured and assembled into a sturdy, eflicient, and attractive toy.

A still further object is the provision of a simplified and inexpensive cane type paper burster which will operate with a certainty and with a relatively small amount of pressure so that substantially any child, small or large, may satisfactorily operate the same.

One of the features of my invention is the provision of a simplified and sturdy mechanism with relatively few moving parts so that the device will operate satisfactorily and enjoy a long life under the most abusive treatment.

Other objects and features of my invention will be apparent from the following description taken with the drawings, in which:

Fig. l is a side elevation in reduced size of the cane device of my invention.

Fig. 2 is an elevational view with one side of the housing removed, and with the paper supporting, feeding and bursting mechanism in crosssection showing the piston and cylinder in the normal nonoperating position.

Fig. 3 is a side elevation of the operating mechanism of the device with one side of the housing removed, and the cylinder broken away to show the position of the piston, at an intermediate position in its paper-bursting stroke, and before the cylinder itself is moved in the housing. The relative downward movement of the housing as between the positions of Fig. 2 and Fig. 3 is readily apparent.

Fig. 4 is a fragmentary elevational view partly in section showing the final paper bursting position of the operating mechanism.

Fig. 5 is an elevational view of the operating mechanism in the operating position of the structure of Fig. 1 turned through in a counterclockwise direction around a vertical axis.

Fig. 6 is an elevational View of the inside of one of the two identical frame members.

Fig. '7 is a sectional view along the line l-'| of Fig. 6.

Fig. 8 is a detailed inside view of the stationary explosion head.

Fig. 9 is a detailed view of the combination paper support, paper feed, and cylinder closing unit.

Fig. 10 is a sectional view of the fastening structure for the two frame members.

In the illustrated embodiment of my invention I provide an elongated handle 10 which may be provided in two parts, telescoping together at a sleeve II rigidly secured on one portion of the handle for the ready reception of the other portion. With this structure the device may be conveniently packaged in a relatively short container, yet quickly fitted together by any user, including a small child. The lower portion 12 of the handle has rigidly secured thereto, a frame or a housing, including a pair of stamped-out identical frame members 13. Each frame member is provided with a laterally extending burr M on each of the securing apertures it along one side of such frame member. When the frame members are placed together in corresponding abutting relation, the burrs along one side of one frame member are inserted in corresponding apertures IS on what would be the opposite side of the other or corresponding frame member. When upset in the final assembly of the frame, the burrs 14 along one side extend in one direction and are upset on the opposite side of the corresponding frame member (Fig. 10), and the burrs on the other side of the frame extend away from their integral frame member [3 in an opposite direction. This is shown particularly in Fig. 1 where the burrs l4 appear on the right-hand side of the figure, while the burrs M on the left-hand side of the figure extend in the opposite direction and are upset on what would be in that figure, the back of the frame. This structure eliminates the necessity of separable rivets or other faswning means thus simplifying the structure itself as well as the manufacture of the device. Inwardly turned flanges ll on the frame members limit the downward movement of the handle, and the metal of the frame members themselves adjacent the apertures 18 in each member is peened to drive such metal directly into the wooden handle and thereby rigidly secure such frame on the handle.

Each of the frame members l3 extend down through convex integral explosion portions I9 and then through a cylinder carrying portion 2i to a cavity 22 which becomes a guide opening for the piston rod when the two frame members are secured together as shown in Figs. 1, 4 and 5, particularly.

The operating mechanism for the paper burster cane is entirely carried by the housing including the two identical frame members Hi. This operating mechanism includes a cylinder 23 slidably carried in the portion 2! of the frame. A piston rod 24, with a downwardly extending striker portion, is slidably supported in the cylinder 23 and retained therein by means of a friction cap 26 which may be driven into the lower end of the cylinder. The friction cap as shown in Figs. 2 and 3 particularly, comprises a one-piece stamped-out member having side walls 2? tapering to such dimensions as to limit the distance to which the cap may be driven into the cylinder. A neck portion 28 is provided on the cap for receiving the piston rod 24 and maintaining the same, together with the aperture 22 of the frame, in alignment in the cylinder and frame. The friction cap 26 prevents the piston from being removed from the cylinder and also acts as a stop for a coiled spring 29 surrounding the piston rod 24 and extending between a washer 3! at the striking end of the piston rod and such cap. The washer 3! is retained against rotation on the end of the piston rod by flattening the sides thereof as shown in Fig. 2 and is retained thereon by means of a striking pad 32 which comprises a piece of very sturdy rubber tubing having an inner aperture 313 considerably smaller in size than the flattened end portion 34 of the piston rod. By virtue of this difference in size, the piece of tubing 32 is frictionally retained on the end of the piston rod and will withstand substantially any type of abuse in the operation of the toy. The striker pad 32 is slightly longer than the end portion 34 so that such end portion will be maintained out of contact with the floor or the like against which the cane is pressed.

The piston itself comprises a cup-shaped leather member 36 secured in the top end of the piston rod 24 by means of an outside washer 3'! keyed to the end of the piston rod as shown in Fig. 2 and an inside washer 38 similarly keyed to the piston rod and retained thereon by upsetting or peening the end of such rod at 39. As will be noted from Fig. 2, the washer 38 is smaller than the inside diameter of the piston cup 36, and the washer 31 substantially the same diameter as the outside diameter of the leather piston. This assembly permits of the maximum flexibility of the leather piston itself, yet positively retains the same in position in spite of the most rigorous use of the toy.

The upper end of the cylinder 23 as viewed in Fig. 2 is rolled to form a flange 4| while a onepiece paper holder plate 42 is provided with a corresponding aperture and downwardly extending flange which is folded around and pressed upon the flange 4| to rigidly secure the paper holder to the cylinder so that it moves therewith. A rubber grommet 43 is snapped into place at the cylinder opening and adapted to engage a stationary explosion head 44 as will be presently explained. As to the paper holder and feeding plate 42, this member together with the fastening means described above, and the feeding mechanism hereinafter described is similar to the structure disclosed in my copending application, Serial No. 123,661. The plate 42 includes a paper carrying portion with slots 343 for receiving paper feeding teeth with said slots provided in an angular extending portion 41 as shown particularly in Figs. 2, 3 and 9. The roll of paper 48 is pivotally carried on a movable handle 49, integral with a mounting axis 5! non-removably secured in the arms 52 and 53 integral with the body portion of the plate i2 and slanting downwardly and outwardly away from such body portion. The handle portion 48 is slightly resilient and snaps into a notch 54 in the arm 53. The paper is fed from the roll 38 over the feed portion 4'! by means of a pivoted jaw 56 having downwardly extending teeth 57 and laterally extending cars 58, the latter pivotally secured in corresponding apertures 59 in each frame member. An integral tail 6| is notched at 62 to receive and retain a spring 63 secured under tension at one end around the pin 64, and bearing at the other end against the tail portion 6! as shown in Fig. 2. An embossed rib 66 extends from the body portion of the jaw upwardly through the tail for strengthening the jaw member as a whole and also acting substantially as a pocket for the end of the spring 63 as shown in Fig. 2.

As previously noted, an explosion head (Fig. 8)

is mounted by means of integral ears 61 in correspending slots 68 on the frame members. Although the explosion head is non-rotatably and non-removably secured in the frame, there is a slight play therein axially of the cane by virtue of the width of the slot 6% and thickness of the metal of the explosion head, so that the latter gives slightly as the grommet 43 presses the paper 48 against the same on an explosion stroke. The head may be pushed up to lie flat against the flange 69 at the top of the slot 68.

The assembly is completed with a retriever spring H extending from a stamped-out ear 12 on the one-piece member 42 and an integral ear 73 on one of the frame members l3. As shown in Fig 1 only one of the ears I3 is used in the assembly of the operating mechanism. With the two frame members 53 identical, however, the extra ear [3 of necessity results, and although only one of the two members has mechanical function, together they balance up the frame from. an aesthetic standpoint.

As to the operation of the torpedo cane, the paper roll 48 is first placed on the handle and axis 49 with the end of the paper being fed across the mouth of the cylinder grommet 43 and down intermediate the spring pressed jaw 56 and the paper supporting portion 41 on the member 42. The rubber striking tip 32 is placed on the sidewalk, floor, or the like and the handle is pushed downwardly. The spring 29 on the piston rod 24 acts to normally hold the piston rod in its extended position and also limit its movement in the cylinder 23. As pressure is exerted, however, the frame rigid on the handle It moves downwardly with reference to the piston rod 24 whereby the piston 36 moves upwardly in the cylinder 23. In the meantime, the spring tension in the spring H and possibly some slight friction between the outer surface of the cylinder 23 and the wall of the frame portion 2! holds the cylinder stationary with respect to the frame, and consequently in the position shown in Figs. 2 and 3. When the piston is moved approximately to the position shown in Fig. 3 with reference to the cylinder, there is sufficient spring pressure built up in the coil spring 29, and bearing against the neck 28 of the cap 26 to force the cylinder upwardly. That is, the spring pressure causes movement between the cylinder and frame so that the cylinder occupies the position shown. in Fig. 4-, with the grommet d3 bearing against the paper 58 and the latter sealed against the embossed aperture portion 715 of the explosion head is. The aperture in the explosion head, of course, registers with the aperture in the grommet '33. On the balance of the downward movement of the handle, the piston is moved rapidly to its uppermost position shown in Fig. l to thereby compress the air intermediate the cylinder and paper sealed across the grommet to cause a bursting of such paper. As can be understood from an examination of Figs. 2 and 4, for instance, the paper is fed across the portion 41 of the paper supporting plate by means of a pivoted jaw 56 on the downward movement of the handle, and consequently the compression stroke of the piston and cylinder. After the paper has been bursted, the downward pressure is removed from the handle and the coil spring 28 forces the piston rod outwardly while the retrieving spring ll pulls the cylinder to a position where the plate t2 engages shoulders it on each of the two frame members it.

Although the assembly of the device is readily understood from the above description. it might be explained that the piston and piston rod assembly is completed and then inserted in the cylinder 23. The cap may then be pushed over the rod M from the bottom thereof and pressed into the end of the cylinder in a tight frictional fit as shown in Fig. 3. The spring 29 is assembled on the piston rod and retained thereon by the washer 3i and rubber striking tip- 32. All of the elements are assembled on one of the frame members is in a jig and then the corresponding frame member may be fastened thereto to retain all of the operating mechanism in or on the two-piece frame in a very sturdy fashion. The toy paper burster cane is, of course, harmless to operate and may be easily operated by any child. Because of its simplicity and ruggedness it will give long and satisfactory service under all types of treatment.
