ATTACHMENT FOR SCREW-DRIVERS;
SPECIFICATION forming part of Letters Patent No. 657,457, dated September 4, 1900. Application led April 16, 1900. Serial No. 13 ,070. (No model.)
T0 all whom it 71mg/ concern,.-
Beit known thatLEMANUEL L. SCHNEIDER, a citizen of the United States, residingat Ann Arbor, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Attachments for Screw-Drivers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth-` ers skilled in the art to which it appertains to make and use the same.
My invention has relation to screw-driver attachments designed and adapted to guide the end of the screwdriver to the nick in the head of a screw and maintain the screw-driver in such position relatively to the'screwthat if the edge of the screw-driver should slip out of the nick it can be immediately re-` placed by simply continuing the rotary motion of the screw-driver.
My invention has for its object the provision of a novel attachment which can be readily removed for the purpose of regrinding or sharpening the screw-driver. A t
In carrying my invention into eiect I provide an attachment of novel form andcon- 4struction adapted to be applied to screw-drivers of the ordinary construction, whether round or liat, and comprising a sliding sleeve or ferrule having a bell-mouth at one end and a screw-threaded gland at the other, a ring adapted to be rigidly secured upon the shank of the screw-driver and capable of beingiev moved, and a spiral spring located within the 1 sleeve and adapted to impel the sleeve toward the end of the screw-driver, so as tocoveror inclose the same, wherebyfthe said sleeve will serve to guide the screw-driver to and maintain it in proper position upon a screw.
My invention consists in the-novel construction, combination, and arrangement :of parts hereinafter described and claimed.
Referring to the accompanying drawings,
Figure l is a vertical sectional view of my improvement applied to a round-shank screwdriver. 'Fig.\2 is a side View of .the same; Fig. 3, a transverse sectional view on the line :ra: of Fig. 2; Fig. 4, a transverse sectional w view of a modified form applied to a at screw-driver; Figs. 5 and 6, detail views of separate parts.
A designates the shank or body of a screwdriver, which is of` the. ordinary form-that is, round-and of equal size throughout its length. AIn applyingV my `attachment to a screw-driver of this form I prefer to cut away the shank on each side of the point or working end, as shown at a a in Fig. l of the drawings, so as to leave a short edge b and aord a bearing for the sliding sleeve C down to a point closely approximating said edge. The sleeve C consists of a hollow cylindrical section somewhat larger in internal diameter than the shankof the screw-driver and having at one end a bell-mouth D and at the other a gland E, that screws into the sleeve and ismilled on its outer side, as shown. A shoulder F is formedon the inside of the sleeve C just above the bell-mouth D, such shoulder being conveniently formed by soldering a ring within the sleeve, and a ring G is fixed on the shank of the screw-driver in any convenient way, as by sweating or soldering it in position, and between the ring Gand shoulder F 4a spiral spring H is arranged, said spring tending to impel theV sleeve toward the end ot' the screw-driver.
The lower end of the bell-mouth D is covered by a rubber or other soft covering I, the purpose ofL-which is to prevent scratching of surfaces against which the sleeve may be `pressed indriving or drawing` a screw.
v `The parts"`being constructed as described are applied to a screw-driver in the following manner: The gland E is slipped on the shank of the drivelgwand the collar or ring G is placed iur position and secured to the shank by sweating or soldering it thereon. Then the spiral spring H is slippedon the shank,V its upper end bearing against the collar or ring G, and the sleeve is placed in position and the gland E screwed into its upper end, thus confinin g and compressing the spring between the collar or ring G and the shoulder F.
Operation: Inusing my improved device the bell-mouth of the sleeve is pressed down over the head of the screw to be operated on, and the screw-driver is then pressed against the screw and turned, and, the sleeve maintaining it in alinement `with the screw, the end of the screw-driver will engage with the nick in the head of the screw, and the screw is then turned in the usual manner. If the screw-driver should accidentally slip out of IOO the nick in the screw, it is `only necessary to" continue the rotarymotion of the screw-driverk form to the shape ofthe 'shankl of the screw` driver. i Having described my invention, I claim- 'l The combination with a screw-driver, "of a)A collar*rigidlysecuredthereon buticapable ofi' being removed, a shelll or sleeve havingai bell-mouth to' receive-a screwand ofy adi-` ameter throughout its` length tof pass freely over'said collar vexcept'ifor a shoulder'or internal flange at its lower end 'andvloosely tting the screw-driver, and internally threaded at its upper end to receive the screw-threaded end of a gland, a glandy fitting on the screwdriver shank'and a-spring' interposed .between the shoulder on the sleeve and the collar on the screw-.d river, the whole constituting an attachment for holding and driving or removmg a screw, and readily removable for the purpose of .regrinding or sharpeningthe screwdriver substantially as described'.
In' testimony whereof I have axed nny signature in presence of two witnesses.
, EMANUEL L. SCHNEIDER.
