RAT CHE T-WRENCH.
No. 895,757. Specification of Letters Patent. Patented Aug. 11,1908.
Application led August 24, 1907. Serial No. 390,009.
. new and useful Improvements in Ratchet- Wrenches, of which the following is a specification.
This invention relates to wrenches and more particularly to ratchet wrenches and has for its object to provide a wrench of this kind which will be extremely simple and;`
which may be thus easily manufactured at a low figure.
Another object is to rovide a structure tending to present an e YAicient wrench which will not be likely to become deranged or broken.
Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown4 and described'may be made within the scope of the claims without departing from the spirit of the invention.
In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is an elevational view of the wrench, Fig. 2 is a longitudinal section taken on line 2-2 of Eig. 1, Fig. 3 is a view showing the inner face of one of the side members of the handle and the 'working parts of the wrench. Fig. 4 is a perspective view of one of the side members, Fig. 5 is a transverse section on line 55 of Fig. 1, taken through the chamber and the pawl.
Referring now to the drawings, the present invention comprises a body portion consisting of two metallic plates 8 and 9, each having an enlarged forward end as shown. The two plates 8 and 9 have their rearward portions secured together, as shown, and have their enlarged forward portions offset outwardly away from each other, these portions being indicated at 10. There is thus formed a space 11 between the portions 10. Circular openings 12 are formed in the portions 10, and receive cylindrical end portions 13 of a revoluble head 14, provided with an angular nut receiving socket 15 and having peripheral ratchet teeth 16.
As shown, the ratchet teeth lie in the space 11 between the portions 10.
The plates S and 9 have longitudinally extending outwardly pressed portions 8 and 9 respectively, there being thus formed longitudinal recesses 16 in the inner faces of the two members, these recesses 16 lying in registration, and communicating with the space 11 between the portions 10 of the plates. There is thus formed a longitudinally extending chamber A, as shown. The portions of the plates S' and 9 at the side of the recesses have attaching rivets 18 engaged therethrough at opposite sides of and adjacent to the forward end of the recesses 16. A similar confining rivet 19 is engaged transversely through the plates S and 9 at the rearward end of the chamber A, and passing therethrough, and is thus located to perform an additional function which will be presently described.
A pawl 20 is slidably engaged in the chamber A, for movement toward and away from the revoluble head 14, this pawl engaging the ratchet teeth 16', to hold the head yieldably against rotation in one direction and positively against rotation in the opposite direction.
A spring 21 is engaged against the rearward end of the pawl, and also rests against the rivet 19, this rivet thus presenting a seat for the rearward end of the spring, and preventing wedging of the spring into the contracted rearward end of the chamber A.
It will thus be seen that a wrench is provided which may be easily manufactured from stock material, the two plates 8 and 9 being stamped in a press of the usual type.
unlikely to become deranged or broken.
What is claimed is:
1. A ratchet wrench comprising a handle having a retaining chamber formed therein to contain moving parts, said handle and chamber portion being integral and formed of two plates stamped from sheet metal and secured against each other, said plates having their forward end portions offset from each other and having also longitudinally extending channels pressed therein and extending rearwardly from the offset portions to form the retaining chamber, said offset portions having registering openings therein, a head carried revolubly between the offset portions and having portions revolubly engaged in the openings, said head having peripheral teeth, a pawl slidably engaged in the retaining chamber and having its forward end yieldably engaged with the teeth of the head, a helical spring carried in the 16, are indicated at 17, and these portions The wrench includes few parts, and is thusr other to form said chamber and bearing against the rearward end of the pawl to hold it yieldably in engagement with the teeth, and a rivet located at the inner end of the chamber to hold the plates together and provide a seat for the spring.
2. In a ratchet wrench, the combination with a handle stamped from sheet metal and having a retaining chamber for sliding parts formed therein and having also spaced arms arranged to carry a revolving head, said arms having registering openings therein said handle, chamber portion and arms being formed integrally from two stamped metal plates secured together and having their forward end portions offset from each arms and having also longitudinally extending channels pressed therein and extending rearwardly from the offset portions to form said retaining chamber, of a head carried revolubl;T between the arms and having portions revolubly engaged in the said openings, said head having peripheral teeth, a pawl slidably engaged in said retaining vchamber and having its forward end yieldably engaged with the teeth of the head, a helical spring carried in said chamber rearwardly of the pawl and bearing thereagainst to hold it yieldably in engagement with the teeth of the head, and a rivet located at the inner end of the chamber to hold the plates together and provide a seat for the spring.
3. In a ratchet wrench, the combination with a handle having a retaining chamber formed therein for sliding parts and spaced arms arranged to carry a revoluble head therebetween, said handle, chamber portion and arms being integral and formed from two plates stampedfrom `sheet metal, of a revoluble head having peripheral teeth, aA
sliding pawl carried in the retaining chamber and a helical spring carried in the chamber rearwardly of the pawl and bearing thereagainst to force it yieldably into engagement with the teeth of the head.
In testimony whereof I alix my signature, in presence of two witnesses.
