Specification of Letters Patent.
Patented Sept. 14, 1915.
Application led April 29, 1915. Serial No. 24,677.
T0 all whom it may concern:
Be it known that I, JULES EMILE Kncnnrsz, a citizen of the United States, and a resident of the city of New York, VVoodhaven, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Expansion-Anchor, of which the following is a full, clear, and eX- act description.
This invention relates to builders hardware and has particular reference to devices in the nature of expansion bolts or the like for use in attaching timbers, planking, studding or the like, to walls of stone, concrete, hollow tile, etc.
Among the objects of the invention is to providewhat I' term an improved expansion anchor as distinguished from an expansion bolt, the main portion of which is adapted to be introduced into a hole formed in the wall, the device including a pair of wings pivoted coaxially of each other but so constructed and arranged with respect to the main bolt as to swing away from each other and toward the outer surface of the wall, whereas the usual practice with expansion bolts is to cause the wings to swing rearwardly from the front face or surface of the wall.
A further object of the invention is to provide a construction which will be stiffer and steadier in practice with respect to certain conditions as explained more in detail below. Y
The foregoing and other objects of the invention will hereinafter be morefully described and claimed and illustrated in the drawings forming a part of this specification in which 'like characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a vertical longitudinal sectional view of my improvement with the parts in position as when being introduced into a hole or cavity in a hollow tile construction; Fig. 2 is a similar view of the wall construction but indicating the improved anchor in locking position in side elevation; Fig. 3 is a vertical transverse section on the line 3--3 of Fig. 1; and Fig. 4 is a similar view on the line 4-4 of Fig. 2.
The several parts of this device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully described and claimed.
Referring more particularly to the drawings, I show at 10 a front portion of a hol'- low tile wall through which has been formed a'hole 10', and 11 indicates the rear wall of the tile or the wall bounding the main cavity 12 of the tile.
'The main part of the anchor construction is a bolt 13 having a head 14 at its inner epd and a groove 15 at its outer end. Adj ace `t the head the neck portion of the boltl is of shortcylindrical form and has a smooth surface indicated at 16. Between the neck portion, however, and the outer end, the bolt is of uniform size and threaded throughout its length.
At 17 is indicated an anchor nut threaded upon the bolt and provided with oppositely extending lugs 18 having the same axis eX- tending from opposite sides of the bolt and preferably. coinciding with one diameter of the bolt. These lugs 18 constitute bearing points or pivots for a pair of Wings 19 and 19 shown herein as being preferably of channel construction and of similar formation, though one is preferably sufficiently wider than the other to embrace said other in practice. Each of the wings includes a jaw portion having teeth 20 formed thereon for biting into the wall or sides of the hole 10. These teeth may be formed in any suitable manner as by striking out the material when the jaws are made of sheet metal or the like. The side portions of each wing arranged in parallel planes serve to strengthen or reinforce the gripping or jaw portions of the wings and are fornled with pivot holes 21 through which the studs or lugs 18 extend. As ,shown best in Figs. 3 and 4, the side portions of the wing 19 lie closely against the outer walls of the side portions of the wing 19. A spring 22 is shown coiled around the nut 17 and with its free ends bearing upwardly on the wings serving to cause them to swing outwardly and forwardly around the axis of the lugs 18.
At 23 is shown a follower somewhat similar in its structure to the nut 17, being internally threaded for coperation with' the threaded portion of the bolt 13, but being adapted at times to operate against the head 14 at the srgooth neck 16 where it will be throw the wings outwardly into substantial by the follower for the purpose of permitung the insertion of the device into the hole or cavity formed in the'wall but with a holding force easily overcome by tappmg upon the outer end of the bolt by a wrench or screw driver or by any suitable means. When the wings are thus free from the follower, the spring acts upon them so as to alinement with each other or at right angles to the axis of the bolt or until one or both. of them are stopped by striking against the s1de of the hole or an inner partition of the wall structure. In other words, the wings under the force of the spring are thrown apart or toward the front face of the wall until they reach a wide open position or are stopped by striking an obstacle.
The next step ordinarily is for the operator to turn the bolt to the left so as to proj ect it outwardly to a greater distance beyond the front face ofthe wall, the wings and 'the nut 17 being held from rotation at such time by the contact, above referred to, with the wall structure. While the bolt is thus being turned outwardl through or along the wings and nut 1 the follower 23 will be carried bodily in the same direction by means of the head 14, such operation continuing until the follower engages one or both of the wings, the end portions of the follower being carried by the bolt b etween both pairs of side portions of the .Wmgs' as illustrated in Fig. 2, or else wlthin the wing portions of the several wings in a position substantially at right angles to that of Fig. 2. In either event, however, the follower will be forced by the action of the bolt .to cause the wings to spread and thereby positively lock them in open position. The full line showing in Fig. 2 may, therefore, be understood as one locking position of the device, the bolt and follower holding the wings In divergent relation to the bolt andthus preventing the withdrawal of the device from-the wall. The outside work, such as studding, planking or the like, may then be applied to the bolt and secured thereon by the use of the usual nut 25 and washer 26. I prefer, however, for the bolt to be turned to thev right after the parts are set in the position shown in Fig. 2, a screw driver or the like being applied to the groove 15 for such purpose, until the head 14 strikes against the bottom of the hole 10 or against such time will not loosen the grip o the.
the.
Wings, and since the internal thread follower is the same as that of the nut 17 and bolt, the bolt may rotate freely therethrough until. the head strikes as described. Then, by giving the bolt Aa final rotation in the same direction, against the rear wall, there will be acorresponding reaction set up through the bolt against the follower and wingsgiving the same a final ,ositivesettin .with a corresponding stiflgning or stea ying of the entire bolt in the` osition shown in dotted lines in Fig. 2. t will be understood that the greater the force applied to the bolt, turning it toward the. rightwith the head bearing against the fixed abutment, the greater will be the' gripping action of.the
lwings against the wall structure supporting the same.
In. setting the device preparatory to its introduction into and through the wallhole 10, the wings are brought into parallelism adjacent the notches 24 of thel follower where they-will be held by the thumb andv finger of one hand while the operator will rotate the bolt toward the left with the other hand to causethe nut 17 and wings to become interlocked lightly with said notches.4
The device may be disconnected from the wall by a reverse of the foregoing operation. I claim 1. In a device ofthe character set forth,
the combination of a threaded bolt having a head at one end. and a smooth cylindricall thereon and movable relatively longitudi nally of the bolt, and anchoring means pivoted coaxially of each other to said nut and movable laterally from the bolt and outwardly with respect to the same toward the outer end ofthe bolt into anchoring position.
3. In a deviceof the character set forth, the combination of a bolt having an external thread, a nut having an internal thread cooperating with the bolt thread and movable relatively thereof along the bolt, a pair of anchoring deyices pivoted coaxially of each other upon said nut, and means serving to cause the wings to swing laterally from each with the head acting other and from the bolt and thence forwardly around their axis into anchoring position. v
4. In an expansion anchor, the combination of a threaded bolt, a nut relatively movable along the same, said nut having oppositely disposed lugs extending laterally from the bolt, a pair of anchor Wings each having a pair of parallel side portions pivoted upon said lugs around the same pivotal axis, and means adapted to be forced between the Wings by the rotation of the bolt to cause the Wings to be swung laterally with respect to each other around their axis into anchoring position.
5. In an expansion anchor, the combination of a bolt having a head at one end, a smooth neck portion adjacent the head and a thread extending between the neck portion and the opposite end, a nut mounted upon the threaded portion ofthe bolt, a pair of anchor Wings pivoted upon the nut, a spring acting between the Wings tending to force them apart and around their axis, and a member journaled upon the neck portion of vthe bolt coperating with the endsof the wings to hold them from rotation.
