RATCH ET-DRI LL.
SPE('JIFIGA'IION forming part of Letters Patent No. 402,096, dated April 23, 1889.
Application iled .Tune 11, 1888. Serial No. 276,753. (No model.)
To all whom it may concern:
Beit known that I, WILLIAM G. MORGAN, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented a new and useful Ratchet-Drill, of which the following is a specification.
My invention relates to improvements in ratchet-drills; and it consists in the construction and combination of parts hereinafter described and claimed.
My object is to construct a ratchet-drill that Will automatically feed itself and at the same time have a continuous revolution at both strokes of the handle, as Well as to construct a cheap and durable drill. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I is an elevation view showing the front plate removed and showing the handles partly in section.V Fig. II is a top view of the drill. Fig. III is a transverse section drawn on the line III III in Fig. I. Fig. IV is a view of the ratchet-wheels detached.
Letter A is an outside casing, in which the parts of the drill mechanism are inclosed. It is provided in its interior with a shoulder, 0o, against which the arm B is fulcrumed, or against which the arm presses or bears when being pulled backward or pressed forward, so as to take the strain off the teat T, and also with a teat, T, which passes through a hole in the handle B. It is provided on its outside `with a sheath, H, made to iuclose and retain a handle, H2, which handle serves to steady the drill.
Letter B is an arm fulcrumed in the casing A, and is provided on each side of the fulcrum with a recess, which passes around more than a half-circle and holds circular ends of pawls d d and allows them to work in said recesses, and contains a handle, H.
c c are two ratchet-wheels fixed on the shaft of thedrill, and which engage the pawls d and d, respectively. `These may be made in one; but by making them separatelyv the one can be made smaller than the other, and thus enable the whole mechanism to be put in a smaller and more compact form and enable the drill-handle to have more thrust and greater action than if both pawls operated on the same ratchet-wheel.
N is the drill-shank, which is made to contain the drill at one end and is provided with a screw at the other. This screw is` designated by the letter S, and is adapted to it in and engage a female thread in a shank, M. This shank is provided with a friction-wheel, W, about its center, and at the end opposite Where the screw end of the drill-shank enters it is tapered off to a point and adapted 6o to turn in the frame-work of the drill. This friction-wheel W is surrounded by a band,. b, which is united at its ends by a set-screw,
V, and has an extension of one or both ends to meet and engage theframe-work of the drill, which will prevent the friction-wheel W from turning when the set-screw is screwed tightly or allow it to turn when it is screwed lightly.
D is the drill.
Now, when the handle H2 is grasped, and the ratchet-casing is irmly held, and the shank M is placed against the frame-work, and the end of the drill proper is placed against v the object to be drilled, and the handle H is moved backward and forward, the drill-shaft and drill are continuously moved in the same direction at the backward as well as the forward thrust of the handle H.
Now, whatI claim, and for which I ask Let 8o ters Patent to be granted me, is-
l. A ratchet-drill composed of an outside casing, A, provided with a fulcrum-rest in its interior portion to engage the arm B, the arm B, having pawls d d engaging ratchet-Wheels 8 5 c c, two ratchet-wheels, c c, handles H H2, shaft N, adapted to hold the drill at one end and containing a thread at the other, shank M, and band b.
2. In a ratchet-drill, an arm, B, fulcrumed 9o in a casing, A, and having a circular recess on each side of said fulcrum for the reception and retention of pawls d d, in combination with a ratchetfwheel and Casin g, substantially as described.
^ In a ratchet-drill, the combination of two W. G. MORGAN.
