United States Patent OPEN-END RATCHET WRENCH Raymond W. Hermanson, Los Angeles, Calif., assignor to Tubing Appliance Company, Inc., Los Angeles, Calif., a corporation Application June 15, 1953, Serial No. 361,710
2 Claims. (Cl. 81-183) This invention consists in new and useful improvements in wrenches and relates more particularly to open-end, ratchet wrenches of the spanner type. One of the objects of the invention is to provide a novel wrench head for open-end wrenches of the spanner type which can be formed of a pair of opposed stampings with a spacer block interposed therebetween, thereby minimizing the cost of manufacture and assembly, while at the same time providing maximum strength and adaptability with minimum overall dimension.
Another object of the invention is to provide an improved work gripping mechanism by means of which a nut or bolt head may be quickly and firmly engaged and so arranged that when the wrench is rotated in one direction the work will be positively turned therewith, rotation of the wrench head in the opposite direction causing the release of the work through a ratcheting action of the work gripping means.
A further object of the invention is to provide a wrench head having a pair of opposed work gripping elements, so arranged that upon reversal of the engaging position of the wrench head, the work piece may be positively turned in opposite rotary directions. Such a design facilitates the use of my improved wrench in applying and releasing both right and left hand threaded nuts by simply reversing the position of the wrench head with respect to the nut.
A still further object of the invention is to provide a wrench head of this type which is simple and sturdy in construction and effective, reliable and durable in operations.
With the above and other objects in view which will appear as the description proceeds, the invention consists in the novel features herein set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.
Referring to the drawings in which numerals of like character designate similar parts throughout the several views,
Fig. 1 is a plan view of a wrench embodying the invention, and arranged in position for positively turning a nut in counterclockwise direction, as in backing off a nut;
Fig. 2 is a view in side elevation;
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2 with the top stamping removed to illustrate the work gripping mechanism. Here it will be noted that the position of the wrench is reversed from that shown in Fig. 1 so that clockwise rotation of the wrench head positively drives a nut as in applying a nut to a bolt;
Fig. 4 is a sectional view of the wrench head taken on line 44 of Fig. 3;
Fig. 5 is a sectional view taken adjacent one of the securing rivets, on line 55 of Fig. 3; and
Fig. 6 is a sectional view taken adjacent the pivot pin for one of the dogs, on line 6--6 of Fig. 3.
Briefly, the invention consists of a wrench head of the spanner type, the opposed arms of which form a work receiving area and carrying two pivoted dogs, the work engaging faces of which are spring biased into engaging position. These dogs are pivotally mounted in recesses in the respective arms and their work engaging ends normally protrude into the work engaging area, being retractable into the respective recesses upon the reverse rotation of the wrench head. Thus, when the Wrench is rotated in one direction the work itself cams the dogs into the recesses to permit the free rotation of ice the wrench head and when the wrench is rotated in the opposite direction the biasing of the dogs causes them to protrude into the work receiving area to firmly grip the work so that the work will be turned with the wrench. A reversal of the position of the wrench headpermits a reversal of the positive engagement thereof with the work piece.
Referring more specifically to the drawings, the wrench head generally indicated by the numeral 10, is formed with a slot 11 extending inwardly of the head and terminating in an opening or work receiving area 12 which is circular in cross section and of a slightly greater diameter than the diagonal dimension of a nut head with which the wrench head is to be used. The wrench head may be formed of a pair of stampings 13 and 14 of a bifurcated shape as shown in Figs. 1 and 3 and having interposed therebetween a spacer block 15 of generally cesses 16, one in each arm of the'head on substantially diametrically opposite sides of the work receiving area 12, said recesses opening into this work receiving area as shown in Fig. 3.
In each recess 16 a dog 17 is pivotally mounted on a pin 18 which extends through apertures provided in the opposed stampings 13 and 14, a spring 19 carried on a pin 20, similarly secured between the opposed stampings, normally urges'its respective dog 17 into work engaging position with its work engaging face lying well into the work receiving area 12. Thus, the normal position of each dog 17 causes its work engaging face 21 to be presented to the work piece in substantial alignment with the adjacent bounding wall 22 of the slot 11. I
As best seen in Fig. 3 the retracting movement of the two dogs 17 within their respective recesses 16, is in opposite directions and the respective end walls 16a of the recesses 16 act as abutments or stops for the dogs 17 to limit their movement into the work engaging area 12. These abutments are also respectively at opposite ends of the recesses 16 so that one rotates clockwise into operative engagement with the work piece while the other rotates in counterclockwise direction into such engagement.
The stampings l3 and 14 and the spacer block 15 are held firmly together by any suitable means. For instance, they may be secured together by rivets such as 23 and preferably the stampings are dimpled inwardly as at 24 and a bushing 25 may be interposed between the body of the rivets 23 and the body of the spacer block 15 with its opposite extremities in firm engagement with the annular face of the dimples 24. The rear portion of the wrench head including the stampings and spacer block, is provided with a squared opening 26 for receiving the squared pivoted end of a handle such as at 27 for rotating the wrench.
In Fig. 1 of the drawings the wrench head is shown in operative engagement with a nut, indicated in dot and dash lines as at 28 and the wrench head is so positioned that upon counterclockwise rotation thereof the nut will be backed off as the work engaging faces 21 of the dogs 17 firmly engage the nut and are held in operative position against the end stops or abutments 16a. Upon rotation of the handle in clockwise direction, the nut will cam the dogs into the respective recesses 16 against the tension of the springs 19, thus either releasing the nut or acting as a ratchet in the progressive backing off of the nut.
In the position shown in Fig. 3, the reverse occurs. That is, the clockwise rotation of the handle 27 causes the operative engagement of the dogs 17 with the nut for screwing the same onto a bolt or the like while the counterclockwise rotation of the wrench head causes the dogs to be cammed into their respective recesses as previously described.
It will thus be seen that a wrench constructed in accordance with this invention is simple and inexpensive in construction, comprises a minimum of parts which are very sturdy and durable. The wrenches release immediately and freely without binding when rotated in one direction and firmly seizes the work for instant operative engagement when rotated in the opposite direction.
