SCREW-DRIVER.
SPECIFICATION forming part of Letters Patent No. 418,167, dated December 31, 1889. Application filed February 25, 1389. Serial No. 301,069. (No model) To all whom, t may concern:V
Beit known that I, THOMAS E. COPELIN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Il 5 linois, have invented a new and useful Improvement in Screw-Drivers, of which the following is a specification.
This invention is designed to render the ordinary screw-driver more easily operable, ro especially7 with light screws, and in putting together stoves and other metal-work where the screw enters an already threaded recess.
. To this end the handle is made in two parts, the outer portion being swiveled upon the inner portion, whichperinits the use of the iingers for rotating the driver while the hollow of the saine hand is pressing against the outer end of the handle. To enable severe work to be done with the same driver, I prozo vide means whereby the two parts of the handle may be locked together, thus permitting its use as a solid driver. These features of the invention are fully shown in the accompanying drawings, in which similar letters of reference indicate like parts, and wherein- Y l Figure l is an exterior view of a driver; Fig. 2, a vertical section of the handle. Figs. 3 and 4 show the abutting ends of the two parts of the handle; and Fig. 5 shows the metal part carrying the pivot upon which the outer part of the handle is swiveled.
In said drawings, A represents the driver, and B and C the two parts of the handle, the part C being swiveled upon the part B. The part B, which is intended to be rotated by the lingers, is given a swell form, and its surface is preferably roughened, as indicated, so that the iingers may not slip upon it. The 4o dividing-line between the two halves of the handle, it will also be noticed, is about mid way ofthe handle. The construction which I prefer for thus swiveling one part upon the other is fully shown in the drawings, and consists of a metallic block D let into the outer half C of the handle and carrying a projecting pivot d. The inner halt of the handle receives another metal block E, which is re however, be used with heavy work by employing one hand to rotate the driver and pressing against the swiveled portion with the other hand or with the body.
To enable the use of the driver as a solid tool, I insert in the block D a spring-bolt G, which is provided with a thumbpiece g, whereby it may be locked from engagement by moving said thumb-piece into the notch 7o h, and which bolt, when released from such In ord er to preeessed to receive said pivot.
notch, will be projected by its spring against the face of block E and enter the first one of the openingsi in the latter which it may encounter in its rotation. Vhen the two 7 5 halves of the handle are thus locked, the driver becomes a solid one and may be used in the ordinary manner of using solid drivers. I prefer to corrugate the surface of the eX- terior half C also, chiefly for convenience 8o when using the driver as a solid implement.
The outer half of the handle should be made of such length as to prevent contact by the palm of the hand with the inner part when the latter is being rotated by the tips of the iingers. In a handle of ordinary size this is accomplished by dividing it about midway, as indicated in the drawings.
I claiml. The screw-driver wherein are combined y a handle made in two parts B and C, united by a swivel-joint, the under part being adapted to be rotated by the fingers of the hand while the palm of the saine hand is pressing upon the upper part, and a locking device` whereby the two parts may be locked together and used as a solid handle, substantially as set forth.
2. The combination, with the screw-driver one or more recesses to receive said bolt', sub- A, of the handle mande iu JcWo parte B and C, stantzly as specified. the, part C being provided with the block D,
f W Y 1 'Y T carrying pivot d, and the part B being pro- HIOMAS L COPLLU" videdwith the block E, recessed to receive Vl'nesses: said pivot, said block .D being also provided EDW. S. EVARTS,
with a Spring-bolt, and the part E having HfM. MUNDAY.
