SPEED WRENCH.
Application filed March 10, 1925. Serial No. 14,565.
The present invention appertains to a speed wrench and has for its principal object to provide a Wrench or the like with means whereby the ratio between the operating member and the operated member,
may be varied as to speed, and wherein the use of the members may be reversed so that the operating member becomes the operated member and vice versa.
Another important object of the invention is to provide in a wrench structure, means for ho ding the head of the bolt while a nut is bein loosened therefrom, said means being ad ustable for different lengths of bolts.
A still further important object of the invention is to provide a simple and eflicient structure in wrenches which will be thoroughly reliable in operation, one which may be manufactured at a comparatively low cost.
Another important object of the, invention is to provide a wrench structure which is stron durable, not liable to readilykget out of or er, and otherwise well adapted'to the purpose for which it is designed.
With the above and numerous other objccts in view as will appear as the description proceeds, the invention resides in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing-- Fig. 1 is a sideelevation of the wrench, showing portions in section, I
Fig. 2 is an enlarged detail section showing the rotating block and its shank,
Fig. 3 is a bottom plan view'of the block and easing therefor with the cover removed,
Fig. 4 is an end elevation thereof,
Fig. 5 is an elevation of the wrench showing an attachment thereon, and
ig. 6 is an elevation of the wrench showing a reversal use thereof.-
Referring to the drawing in detail, it will be vseen that 1 designates a cylindrical casing having one end thereof closed by a plate or the like 2. A tubular handle 3 extends centrally from this pla'e closure 2 and has a knurled sleeve 4 fixed thereon in order that the casing may be held stationary as will be brought out more clearly hereinafter.
A block 5 is rotatably mounted. in the easing 1 and is provided with an elongated shank 6 extending from one end thereof through the tubular extension 3 and is provided with a squared extremity 7 in order that a crank handle 8 may be engaged thereon. This crank handle 8 is provided with a plurality of square openings 9 for this purpose. 2 I
A recess 10 is provided in the end of the block 5 opposite to that from which extends the expanslon 6 and the inner end thereof is provided with an internal gear sectioii 11. A circular bore extends from the recess 10 into the shank 6 terminatin in said shank 6 a suitable distance from t e block 5 as is indicated at 12. A shaft 13 is slidable in this bore 12 and also rotatable therein and has mounted thereon for rotation therewith a pinion 14 which is in mesh with pinions 15 carried by pins 16 and extending into the block 5. These pinions 15 are in mesh with an interior annular rack provided on the casing 1 as at 17. p
A closure cap 18 is threaded on the easing and is provided with a tubular extension 19 through which extends the shaft 13. A closure 20 is threaded on the end of the tubular extension 19 and the shaft projects through this closure and is adapted'to receive a couplin 21. An extension rod 22 is engaged in t 1e coupling and carries the socket 23. This socket 23, ofcourse, may be applied directly to the end of the shaft 13. A shoulder 24 is fixed on the shaft 13 within the tubular extension 19 and is slid: able with the shaft. A shoulder 25 is fixed at the upper end of the tubular extension 19.
adjacent pinion 14 and shaft 13 is slidable therein. 3
A spring 26 is disposed about the shaft within the tubular member 19 and impinges against the shoulders 25 and 24. The shoulder 24 normally rests on-the cap 20 so that when the shaft 13is slid to connect pinion 14 with gear section 11 for direct rotation with block 5, the spring 26 will be compressed and placed under tension to bring the parts back to the normal position shown in Fig. 1.
When the shaft 13 is slid as just described, it will be seen that the pinion 14 may be meshed with the gear section 11, thereby fixing the shaft 13 with the block 5 for rotation directly therewith. When the pinion 14 however, is in its normal position as shown in Fig. 1, upon operation of the shank'6 by the crank 8, the block 5 will be rotated in the casing, thereby revolving the pinions 15 in an orbit and since they are meshed with'the annular rack 17, these gears will rotate while revolving in the orbit, thereby rotating the pinion 14 at a great rate of speed. The rotation of this pinion, of course, rotates the shaft 13 and the attachments connected thereto.
A frame F is mounted on the handle sleeve 4 by means of clamps having rods 31 extending. therefrom and supporting'a ring 32. The hand, therefore may be inserted through this ring and grasped about the handle sleeve 4 and the ring will then be disposed about the wrist so that the casing 1 may be held against rotation. I
In Fig. 5 I have shown an attachment which consistsof a sleeve 34 disposed on the extension rod 22. A sleeve 35 is slidably mounted'on the'sleeve 34 and carries an L- shaped rod 36 which adjustably supports a bracket 37' havinga socket 38 alined with socket 23. The bracket 37 is in the form of a rod having a sleeve 39 at one end slidable L over the L-shaped rod 36 and held in difi'er- I out positions thereon by means of a pin 40 passing through one of the plurality of openings 41 Thus the bolt head will be engaged in the socket 38 first and the sleeve 39 will be adjusted on the L rod 36 until the nut is engaged in the socket 23.
A final adjustment may then be made by pushing the sleeve 34 into engagement with the socket 23 and sliding the sleeve 35 away from the socket 23, at which time the pivoted pawl 42 carried by the sleeve 35 and extending through an opening 43 therein, will engage rack teeth 44 onthe sleeve 34.
If desired, the rods 31 maybe provided with apertures as is indicated at 45 in order that the extension rod 22 may be inserted therethrough to form an anchoringkey to engage a member inserted through the ring 32 or with which the hand of the arm inserted through the ring may be .engaged toprevent rotation of the casing when the wrench is used reversed. By referring to Fig. 6 it will be seen that the crank 8 may be engaged with the shaft 13 and the socket with the shank 6, thereby. reversing the ratio of gearing between the socket and the scription, and that numerous changes in the details of construction, in the proportions, in the materials, and in the combination and arrangement of parts as will be hereinafter claimed.
Having thus described my invention, what claim as new is In a reversible wrench, a casing, a sleeve extending upwardly from one end of the casing, a block rotatably mounted in the casing and provided with a recess having an internal gear section formed therein, an elongated shank extending upwardly from the. block through the sleeve, an annular rack carried by the casing, radially disposed 'pinions *rotatably carried by the block and meshing with the annular rack, a tubular extension on the opposite end of the casing, a shaft slidably extending through the tubular extension and into'the recess'of the block, a pinion fixed to the shaft and meshable with the radiallydisposed pinions, a spring seated in the tubular extension and adapted to normally retain the pinion in mesh with said radially disposed pinions, a crank, and a socket member, said crank and said socket member being interchangeable on the free ends of the shank and shaft respectively.
In testimony whereof I aifix my signature.
CLAUD CALLISON.
