Y T0 alli'whom 'it may concern:
Be it known that l, WILLIAM J. BAUER, a citizen-of thellnited States, and a resident of New York, inthe county of New York and State of New York, have invented certain 'new and useful lmprovements'in Spiral Tool-Drivers, of which the following is a specification.
The invention relates to improvements in spiral tool drivers, such as screw drivers or like articles, uvherein the tool member or a holder thereforis automatically rotated by pushing down on the handle portion of the screw driver or like article.V It has for its object to providel for an inexpensiveand satisfactory article of this type, and also to se arranged the parts that the screw driver may be used., in the usual mannerfor service` in withdrawing screws, the tool member then operating in reverse direction, as is well understood.
ln the accompanying drawings, which Figure 1 is a ve` proved screw driver.
Fig. 2 1s. a horizontal section taken on the line 2-2, Fig; 1, looking in the direction of the arrows.
Similar characters of reference designatel Referring to the drawings, 10designates a tubular member terminating at its .lower edge in .a series of cireularly arranged ratchet teeth 11. The other end'of the tu bular member is securely held to the handle portion 12 as through a pin 13 or similar securing means. This pin passes, also, through'a member or ring 14. inserted within'said end of the tube and provided with a series of inwardly-directed ratchet teeth arranged circularly along its inner edgeand corresponding in number tothe teeth. 1.1 of
said tubular member. l/lithin tube 1d is mounted for reciprocation and rotation a tool rod or member 15, the inner portion of which is spiralllyformed as by twisting a square rod, the lower and outer portion,
however, remaining straight. This tool member 15 carries at its inner end a ringshaped member 16 having an upper toothed or ratchet portion 17 whose teeth correspond to and are adapted to engage with the similar but oppositely directed teeth of ring 14E,
4forthe purpose hereinafterset'forth,
ed to contact at the lower limit of its travel with a circular indentation 18 of the said tubular member, which indentationy thus forms a stop to limit the outward movement of said rod 15. About said rod 15 and beyond the teeth 11 of tubular member 10 is mounted a cylindrical 'or cup-shaped member 20 having inwardly projecting ratchet teeth lrcorresponding to the teeth 11 and adapted Ato engage therewith. Member 2O is provided with an inwardly-turned flange which is squared toreceive the rod 15,; and, when not engaged by the teeth 11, is free to rot-ate with said rod. ln order to retain membergQO in position on the rod, a ferrule or cylindrical 4shell 22 is placed over, same on said rod and its inner end held thereon by being turned in to lit the indentation 18 of the tubular member 10. The lower portion, moreover, is turned in to provide a flange and a rod, guide 23. Betweenv the flange 23 and the bottom of member 20 is located a suitable spring member 24 which normally fort: s said member E20 into engagement lwith the uwer end of tubular member 10, the two sets` of teeth interlocking.
The said tool member 15 may itself constitute the tool,4 or any suitable means may be provided on the tool member 15 to receive a suitable tool 25. For example, a chuck 26 may be secured to end of rod 15, said chuck being split longitudinally and adapted to receive over same a nut 27. Furthermore, a
cylindrical portion or sleeve 'Z8 may be provided over the connection between chuck and outer end of rod 15, as by providing a circulargroove 29 therein, and into which fit p`r0 jections 30 from the said sleeve. lt is to be noted, also, that the inner end of chuck 26 stopped by the indentation 18. In doing this, cylindrical member Q0 will rotate freely as the rod is pulled therethrough, the teeth 21 being disengaged from teeth 11 as the resistance of spring '24' will be overcome by the pulling action. owever, upon pushing .down uponthe screwdriver,'teeth 21 and 11 ing ratchet teeth will come into engagement; and as the tubular member moves relatively to rod 15, the member 2O being thus locked to the said tubular member, the rod 15 is rotated through the action of the spiral portion of the rod in passing through the squared central portion of'member 2() until the limit of travel is reached. Thereupon, the rod 15 must again be pulled out and the cycle repeated.
Should it be desired-to operate the screw driver in the reverse direction for service in withdrawing a screw, the tool is used in the position in which the tubular member has been pushed down substantially to its limit of travel, whereupon a slight, further downward movement will cause theteeth of member 16 to engage |with teeth of ring 1l, and thus lock the handle portion 12 to the tool rod and form, for the time being, an integral portion thereof. The teeth of member 16 being similar in character and number to the teeth of ring 14, there will be no jamming action or difficulty from improper engagement, especially in view ot' the fact that as the straightportions of the rod slide through the member 20, no rotation of the said rod takes place.
