Description

G. H. TALBOT, OF BOSTON, MASSACHUSETTS.
l GIMLET-HANDLE.
Specification ofLetters Patent No. 15,907, dated October 14, 1856.
To all whom if may concern.'
Be it known that I, GUILLAUME H. TAL- Bor, of Boston, in the county of Suifolk and State of Massachusetts, have invented a new and useful improvement in the handles or stocks of gimlets, augers, corkscrews, and other tools or instruments for boring or other purposes which operate with a rotary motion; and I do `hereby declare that the following is a full, clear, and exact description of the same,reference being had to the accompanying drawing, forming part of this specification, in which- Figure l is a central section of a gimlet handle in a plane passing through the axis of the gimlet, showing the internal gearing all entire. Fig. 2 exhibits a similar section of the handle, and shows the gearing also in section. Fig. 3 is a central section of the handle in a plane perpendicular with the axis of the gimlet.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in the application within the tool stock or handle of such an arrangement of ratchet or ragwheel gearing as will enable the tool or instrument to be rotated in either direction at the pleasure of the operator by turning thestock or handle back and forth in opposite directions and at the same time pushing it from or pulling it toward him, the pushing of the handle from him causing the tool or instrument to rotate in one direction and pulling it toward him causing it to rotate in the opposite direction.
.To enable others to make and use my in-` forth.
C is a socket tted to turn freely in the handle and constructed to receive the gimlet D and hold it securely. The portion A, A', of the handle is divided in theplane of the section represented in Fig. 3, into two parts A A to admit of the insertion within it of the ratchet or ragwheel gearing. Each of these parts A and'A contains a central circular cavity within the back part of which is placed one of two ragwheels or flat circular ratchets a. a These ragwheels are firmly secured into their respective parts of the handle so as to be incapable of turning thereinand when the two parts A, A', are
of sliding within them and they upon it the said wheels c, c, can only turn with the socket. The ragwheels c, 0', match one with the rag wheel a, and the other with a and a spring e is applied between their backs which tends to force them toward their fellows, a and a but their movements in such directions are limited by two pins 03 d which are inserted through the shank of socket and protrude a little from either side thereof. The socket O is also allowed a certain amount `of movement within the handle A A', which movement is limited in one direction by the end of the shank E coming in contact with the back of its bearing in the part A, of the handle, as shown in Fig. 2 and in the other direction by the pin ci coming into contact with a shoulder c', made within the rag wheel a', around the interior of the bearing of the shank in the part lA of the handle.
The two parts A, A, of the handle are secured together by screws f, f, after the insertion of the socket and ratchet gearing and the socket is prevented coming out by the pin d catching the shoulder z'.
In using the gimlet the operator takes the handle portion A A firmly in his hand and turns it backward and forward without releasing it from his grasp. In boring he presses the handle away from him and toward the gimlet and by so doing brings the rag wheel a. in contact with the pin d which holds it out of gear with c while the rag wheel a is brought into gear with c by the spring e; but to withdraw the gimlet he pulls the handle toward him and away from the gimlet and by that means brings the rag wheel a in contact with the pin Z which holds it out of gear with o while a is brought into gear with o by the spring e.
The teeth of the ratchets a, c, are set to engage and turn the gimlet when the handle turns to the right and those of the ratchets a', c', to engage and turn the gimlet when the handle turns to the left, the springs aly disengage itself from a, or a, When the handle turns in the opposite directions to those above-named, under each condition of the ragvvheels.
Instead of using a socket c, the gimlet may be made With a shank fitted With rag- Wheels c c and a spring c, and provided With stops Z d, like the shank E, of the socket C butit is more economical to construct the handle With a socket as described to make one handle serve for several gimlets or other instruments.
For corkscreivs or other instruments Which do not require to be changed the shank of the instrument itself Will ybe litted to the handle in the same Way as the socket C is fitted.
The gimlet handle serves to illustrate sufficiently the application of myy invention Without describing its application to other instruments. It may be applied in the same manner to other instruments as bit stocks, &c. Without any modification further than what is required by the form of the stock or handle is necessary, and no change in the arrangement of the ratchet or ragwheel gear is necessary. The arrangement of the gearing is however capable of some modification Without changing the character of the invention, as for instance the ratchets or ragwheels c c which are attached to the socket C or shank of the tool may be attached rigidly and the ratchets a a be allowed a suiicient movement in the handle under the influence of springs to admit of their proper operation to disengage themselves from c c in turning one Way. The same result may also be eected by other modifications of the ratchet gearing not necessary to be here mentioned.
I do not confine myself to the particular arrangement or ragwheel gearing represented in the drawings. But
lVhat I claim as my invention and desire to secure by Letters Patent is The application Within the stock or handle of the gimletor other tool or instrument of an arrangement of ratchetor ragWheel gearing operating substantially as herein described so as to enable the tool or instrument to be rotated in either direction at the pleasure of the operator by turning the handles back and forth in opposite directions and at the same time pushing it from or pulling it toward him, the direction of the rotation being varied by the pushing or pulling of the stock or handle.
Gr. I-I. TALBOT.
