REVERSIBLE RATCHET-WRENCH.
SPECIFICATION forming part of Letters Patent No. 745,397, dated December 1, 90
Application filed August 18, 1903. Serial No. 169,906. (No model.)
To all whom, it may concern/.-
Beit known that I, LLOYD O. SNYDER, a citizen of the United States, residing at Farmington, in the county of Marion and State of West 5 Virginia, have invented a new and useful Reversible Ratchet-Wrench; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperro tains to make and use the same.
The invention relates to a reversible ratchet-wrench, and has for its object to improve the construction of wrenches and to provide an exceedingly simple and inexpensive one of great strength and durability adapted to be readily adjusted to a nut and capable after it has been once adjusted of being oscillated to screw the nut on or off without readjnsting it.
A further object of the invention is to provide a wrench of this character adapted to be readily set to rotate a nut in either direction and capable of operating Within a very small space.
With these and other objects in view the invention consists of the novel construction and arrangement of parts hereinafter described and shown, and particularly pointed out in the appended claims.
0 In the drawings forming a part of this specification, and in which like numerals of reference designate corresponding parts, Figure l is a perspective view of a Wrench constructed in accordance with this invention. Fig. 2 is 3 5 a longitudinal sectional View of the same. Fig. 3 is a longitudinal sectional view taken at right angle of Fig. 2. Fig. 4 is a transverse sectional View. Fig. 5 is a detail view of the adjustable jaw. I
Referring to the drawings, 1 designates a shank or bar provided at one end with a bandle 2 and having a circular head 3 at its otherv end forming a bearing for a ratchet-wheel 4, which is retained in the bearing by a removable ring or plate 5. The circular head is provided at one face with'an annular flange 6, and the ring or plate'5 cooperates with the flange 6 to form a groove for the ratchetwheel. The shank or bar 1 is provided at its outer end with a bifurcation 7, in which are pivoted a pair of oppositely-disposed pawls 8, mounted on pins 9 and engaged by sides or portions of a spring 10, which is adapted to hold either of the pawls in engagement with the ratchet-teeth, whereby when the shank or bar is oscillated the ratchet-wheel is rotated in either direction. The pawls project outward and are adapted to be readily grasped, and the spring also operates to hold either of them in its disengaged position.
The ratchet-wheel is provided with a rectangular opening 11, in which is arranged an adjustable jaw 12, which cooperates with a fixed jaw 13, located at one end of the opening. The adjustable jaw is recessed at opposite sides at 14 to receive the ratchet-wheel, whereby it is slidably connected with the same, and it has a removable" plate 15, operating in recesses 16 of the ratchet-wheel and havingits outer face flushed with theadja- 7c cent face of the ratchet-wheel. The jaws project from the opposite face of the ratchetwheel, and the adjustable jaw, which is movable to and from the fixed jaw, is locked at any desired adjustment bya pivoted catch 17.
The pivoted catch 17 consists of a T-shaped plate arranged within the opening of the ratchet-wheel and securedto the movable jaw by a suitable fastening device 18. The T- shaped plate forms a handle or grip and a pairof oppositely-disposed arms 19, which are adapted to be swung cutoff and into engagement with opposite recesses of the sides of the ratchet-wheel.
The wrench is placed on a nut, and the adjustable jaw is moved against the same and locked in its adjusted position. The proper pawl is engaged with the ratchet-Wheel, and the shank or bar is oscillated to screw the nut on or off. The circular head forms a nar- 9o row rim for the ratchet wheel and enables the wrench to operate in a very small space.
What I claim is 1. In a wrench, the combination of a shank or bar, having a head, provided with a bearing, aratchet-Wheel mounted in the bearing, and having an opening, oppositely-disposed spring-actuated pawls arranged to engage the ratchet-wheel, an adjustable jaw mounted in the opening of theratchet-wheel, and a lock- Ioo or bar having a bearing, a ratchetwheel mounted in the bearing, and provided with opposite notches, an adjustable jaw slidably interlocked with the ratchet-Wheel, and a T- shaped catch pivotally mounted on the adjustable jaw and engaging the notches, substantially as described.
In testimony whereof I have hereto affixed my signature in the presence of two Witnesses.
