UNITED STATES PATENT OFFICE.
WM. Gr. A. BONW1LL,OF DOVER, DELAWARE.
IMPRVEM ENT IN SCREW-DRIVERS.
Specification forming part of Letters Patent No. 50,328, datcd October 10, 1865; antedated August 27, 1865.
To all whom it may concern:
Be it known that l, W. G. A. BoNwILL, of Dover, in the county of Kent and State ofDelaware, have invented a. new and useful Improvement in Combining a Screw-Driver with other Tools; and I do hereby declare that the lollowing is a full, clear, and. exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specilication, in which- Figure l is a face view ot' a screw-driver which has a conntersink combined therewith. Fig. 2 is an edge view thereof, the countersink being turned out of the way.
Similar letters ot'reference indicate like parts.
This invention consists in combining with a screw-driver any other tools which are commonly used in connection therewith, such as a countersink, gimlet, reamer, duc., by means of a sliding socket andjoint, the socket being Inaderemovable or fixed.
A is a screw-driver, which may be ot' ordinary construction as to shape and material.
B is a countersink, which is here taken as an example to show how that and any other tool may be combined with a screw-driver so as to be operated by means ot' that implement with as much efciency asthough they were cach supplied with separate handles.
O is the shank of the countersink. lt is shown here as being made hat, so as to lie snugly against the face ot' the screw-driver when extended for use. A slot, d, of considerable length is formed in the upper end ot'the stock G, parallel with its dat side, for the purpose of making ajoint by which the countersink can be turned down lor work or turned up out of the way.
D is a sliding socket fitted to the blade of the screw-driver, and to which it is capable of being` clamped by means of a set-screw, E, through its back, which is strengthened for the purpose of receiving the screw and enabling it to hold the socket steady. The face of the socket has two flanges, b, extending from it at right angles, and which are far enough apart to receive the stock of the countersink between them. They are connected to each other by a stout pin, a, which also serves as thejoint-pin for the stock of the countersink, beinginserted through the slot or loop dformed in the end of that stock. The length of the stock C, the length ot' its slot d, and the position ot' the socket D upon the screw-driver are adjusted with reference to each other7 so that when the countersink is in the position shown in Fig. l it will clear the end of the screw-driver. In order to turn it up from that position and enable one to use the screw-driver, it is only necessary to move the countersink down until the hinge-pin c strikes against the outer end ot' the slot d, when the stock O can be turned up and laid against the upper part of the screwdriver. It is then secured in this position by pushing the stock downward until the pin a strikes the inner end ot' the slot. The same movements reversed will restore the countersink to the position shown in Fig. l.
Any other tool capable ot' being operated by' means of a handle like the handle ot' a screwdriver may be combined therewith in the same way. The socket D may also be held by friction or be locked to the blade oi the screwdriver by a spring-locking device or be permanently fastened toit; and by removing the set-screw to one side or employing some other convenient mode of fastening the socket or collar cl another tool can be applied to the other side of the screw-driver, and the like may be done on each edge of the screw-driver.
l claim as new and desire to secure by Letters Patent- ()ombining a countersink or other tool which can be operated by a straight handle with a screw-driver by means ot' a socket, D, and a sliding joint, substantially as and for the purpose above described.
. WM. G. A. BONWILL.
