llNITED STATES PATENT OFFIC JAMES SANGSTER, OF BUFFALO, NEWV YORK, ASSIGNOR TO HIMSELF AND JUDSON B. ROSE,
OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 391,391, dated October 16,1888.
Application filed September 4, 1888. Serial No. 284,573. (No model.)
To ctZZ whom it may concern.-
Be it known that 1, J AMES SANGSTER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Breast-Drills, of which the following is a specification.
My invention relates to certain new and useful improvements in breast-drills, whereby the effectiveness of the drill is materially increased and at the same time very much less labor is required to operate it, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 isa front elevation; and Fig. 2 is a side elevation, the two figures showing clearly the invention and its operation.
The object of my invention is to provide a simple means in a breast-drill to draw the drill up to its work with sufficient force to drill into hard materials effectively with very little of the usual pushing force against the breastplate, and thereby relieve the operator from the fatiguing labor attending the use of such drills as usually made.
In said drawings, in which a breast-drill of the ordinary construction is shown, 1 is the drill-body, of which the breast-plate 2, the yoke 3, and tubular portion 4forma part. The shank of the spindle 5 passes through the tubular portion 4 into the yoke 3 and receives a bevel gear-wheel, 6, (rigidly secured to it,) through which it passes sufficiently far to fit into a small depression or seat adapted to receive it.
Mounted on the body of the drill, on a pin so as to turn easily, is a larger bevel gearwheel, 7, adapted to gear in with the wheel 6, and provided with an arm, 8, and handle 9 for turning it.
At the outer end of the drill-spindle 5 is a common drill, 10, secured in place by a chuck, 11, of any well-known construction; but as the whole of the drill as far as at present described is old and of well-known construction a further description here is unnecessary.
On the body of the drill I mount on a spindle, 12, (shown in Fig. 1,)so as to turn easily thereon, a cylindrical portion or barrel, 13, having a hand-wheel or large thumb-pieces, 14, by which it may be grasped by the hand to turn it. Rigidly secured to the portion 13 is a pin, 15. On the inner end of the portion 13 is a small ratchet-Wheel, 1S, and to the body 1 of the drill is mounted on a pin, 19, a pawl, 20, adapted to be easily engaged or disengaged from the ratchet-wheel 18, for purposes which will be more clearly shown hereinafter.
The operation of the invention is as follows: While using the drill, a piece of strong cord, 16, (a fine piece of cable or chain would be an equivalent for the cord or twine,) is used. It is preferably tied together so as to form an endless cord, and placed around the object 17 to be drilled, substantially as shown in the drawings. The opposite end is thrown. over the pin 15. The drill being placed substantially as shown, and the hand-wheel or thumb-pieces 14 being turned in the direction of the arrow V, will cause the cord 16 to be wound around the barrel 13, which operationwill draw the drill with considerable force against the object to be drilled. Vhile using the drill in this way the breast is placed, as usual, against the breast-plate, but with only sufficient force to keep it in position. None of the usual exhaustive breast-pressure against the plate is required, because a far greater pressure can be obtained by turning the barrel 13, as before mentioned.
Instead of an endless cord, 16, being used, asingle cord or its equivalent having a loop at each end, or any device adapted to catch on to the pin and to hold on to the object to be drilled or a portion of the object to be drilled, may be used.
If for any reason it should be necessary during the operation of drilling to let go of the hand-wheel for the purpose of catching a fresh hold, the pawl 20 is thrown into gear with the ratchet-wheel 18, thereby holding the cord taut. This operation is required only when drilling deep holes and when more than one turn of the barrel 13 is necessary. Otherwise the use of the pawl and ratchet is not required.
I claim as my invention- 1. In a breast-drill, the combination therewith of abarrel, 13, pivoted to the body of the 3. In a breastdrill, the combination theredrill so as to turn easily 011 itsbearing, a means with of a barrel, 13, provided with aratchetfor grasping it by the hand to turn it, and a pin wheel, 20, a pin, 15, and mounted on the body 15 for holding the cord as it is wound around the of the drill, so as to turn easily thereon, a
5 barrel while drawing the drill up to its work, I means for turning it by hand, and a pawl for substantially as described. engaging with the ratchet-wheel, substantially 2. In a breast-drill, the combination thereas and for the purposes described. with of a barrel, 13, mounted on the body of T r the drill on a bearing, so as to turn easily JAMES SALGSPER' IO thereon, a meansfor turningit by hand, a pin, Vitnesses:
15, and a cord, 16, the whole combined for HARRIET JoHNsoN, joint operation, substantially as described. ROBERT A. GEARY.
