RATCH ET-DRI LL. y
SPECIFICATION forming part of Letters Patent No. 509,893, dated December 5, 1893.
Application led August 17, 1893. Serial No. 483.392. (No model.)
To @ZZ whom, it may concern:
Be it known that I, WILLIAM GRInssER, a
citizen of the United States, residing at Phily adelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ratchets and Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to ratchets and drills, and has for its object to provide a device of the character set forth, having a superior operation, and which will save labor and time by a continuous rotation of the drill, irrespective of the direction of operation of the mechanism.
With these and other objects in view, the invention consists of the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.
In the drawings: Figure -1 is a view in sectional elevaticn of a drill, embodying the invention. Figs. 2 and 3 represent detail plan views of pinions employed in connection with the device. Figs. 4 and 5 are plan views of a ratchet collar. Fig. 6 is an enlarged view of the automatic feed attachment.
Similar numerals of reference are employed to indicate corresponding parts in the several figures.
Referring to the drawings, the numeral l designates a main operating or master beveled gear having teeth on the front face thereof, and mounted on a shaft 2, which is operated by a handle or crank 3, in an oscillating manner. The shaft 2 is supported by a housing 4, secured to the drill` stock 5, which has screws 6, and 7, at the upper and lower ends thereof and a drill-socket 8 at the bottom of the same. On upper and lower portions of thestock 5, adjacent to the points where the housing 4 :is connected thereto are mounted small beveled pinions 9 and 10, having obi long or rectangular slots 11 therein which are reversely arranged, and at their opposite ends are formed circular. The said slots 11 permit one pawl to remain in contact with the ratchet teeth of the ratchet walls 15 and 16 before the other pawl is disengaged in the movement of the said pawls from the ratchcts, and also permit the gears 9 and 10 to be started slightly in advance of the actual work to evade shock and strain on the drill bar. These pinions 9 and 10 mesh with the master gear 1 and are operated thereby., In the said slots 11 are mounted vertically disposed ratchet pins 12, having their operating or engaging ends beveled at an angle of about sixty degrees as at 13. Above the upper set of said pins and below the lower set of the same are mounted springs 14, which normally force the said pins into engagement with ratchet collars l5 and 16, the collar 15 having right-hand teeth on the upper face thereof, and the collar 16 having left hand teeth on the lower face of the same. The upper screw of the shank is supplied with a grip shell 17, which may be provided with a center pin as at 18, for a well-known purpose. It will be understood that the parts are all properly supported by shoulders on the shank, and thereby held in position. In operation the handle or crank 3 is oscillated in one direction to cause the upper ratchet pins to engage the upper ratchet disk and turn the drill socket and the drill carried thereby toward the right. On the return movement of the said handle, or crank, the upper ratchet pins play over the teeth of the ratchet disk with which they engage, and the lower ratchet pins take into the teeth of their ratchet disk and cause a continued operation toward the right. This movement is permitted through the c0nstruction of the slots in the pinions 9 and 10, and a continuous rotation results from an oscillation of the said handle or crank. It will be seen by this means, that a great deal of labor and time is saved with a superior function and result. I
To form an automatic feed, a shell or casing 19 is mounted over the center pin, at the upper end of the shell 17, heretofore referred to. lVithin the said shell or casing 19, is mounted a rubber washer 20 having a steel ring 2l driven tightly over the center pin and resting thereon. Below the rubber washer is a steel washer22 audit is loosely fitted on the center pin or shell. The said rubber washer and the steel washer 22, are held against the steel ring 21 by a lower disk or washer 23, and keys 24 are passed through the rings 21, washer 20, and washer 22 and are employed ICO to keep the rubberwasher 2O and steel washer 22 froln slipping on t-he ring 2l. The lower washer or disk 23 is held immovable by keys or pins 25, against a cup or bottom 26, which is secured to the lower edge of the casing 19, and the said disk 23 is thereby prevented from turning while it normally snugly tits against the center pin of the shell 17. It will thus be observed that a friction mechanism will be instituted between said devices and the lower disk and when the parts are properly tightened, they have a tendency to hold the grip or shell of the drill through the rnedium of the center pin, when the screws of the drills are operated, it being seen that the upper screw is the feed screw.y When a certain pressure is on the feed screw, the pressure on the rubber washer is not tight enough to feed more until the pressure has been released on the center pin through the lnedium of the crank handle and the continucus feed thereby instituted.Y It will be understood that the attachment just described may be dispensed with and the center pinused alone if desired, f
Having thus described the invention, what is claimed as new isl. 1n adevice of the character set forth, the combination of the drill shank or stock, upper and lower ratchet disks having toothed faces arranged outwardly from each other, and the teeth reversely positioned to formi-ight and left ratchets, oppositely disposed pairs of ratchet pins arranged in vertical planes and having their inner ends beveled and engaging` said ratchet teeth, pinions having reversely arranged slots therein in which said ratchet pins are mounted, springs for keeping said ratchet pins in engagement with the ratchet teeth, and a single master gear engaging both of said pinions, and adapted to be operated by the oscillationfof the crank han- WILLIAM GRIESSER.
