PATENTED JULY 3, 1906. J. R. LAWRENCE.
FILE HOLDER.
APPLIGATION FILED AUG. 2. 1905.
UNITED STATES PATENT OFFICE.
FILE-HOLDER.
Specification of Letters Patent.
Patented July 3, 1906.
Application filed August 2,1905. Serial No. 272,356.
To all whom it may concern:
Be it known that I, JOHN R. LAWRENCE, a citizen of the United States, residing at lVaukegan, in the county of Lake and State of Illinois, have invented new and useful Im rovements in File-Holders, of which the fol owing is a specification.
This invention is a file-holder particularly adapted to hold a file for sharpening the blades of lawn-mowers, shears, skates, and
similar blades having a comparatively thick or obtuse edge.
The object of the invention is to provide a holder in which the file may be adjusted so as to vary its angle to suit the bevel or angle of the edge being sharpened. This object may be effected in various ways, one or more of which are disclosed in this application.
In the accompanying drawings, Figure 1 is a view of the face of the device. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a side elevation. Fig. 4 is a top or back view. Fig. 5 is an end view. Fig. 6 is a plan view of the turning bar which holds the file. Fig. 7 is a top plan view of a modification. Fig. 8 is a plan of a modification with respect to the means for holding the file in the turning bar.
Referring specifically to the drawings, 6 indicates a metal block or casting having in its bottom or face a longitudinal slot 7, the edges 8 of which are parallel to each other and form guides for the plain side of the edge of the blade. The slot 7 communicates with a circular longitudinal hollow or bore extending from one end of the block to the other, as indicated at 9. This bore receives at a snug fit a round turning bar or piece 10, which is grooved lengthwise, as at 11, to receive the file 12, which fits in the groove. The turning bar is properly located in the bore to present the face of the file at the slot 7, and the bar may be turned to present the face of the file at various angles to said slot and to the edges 8 thereof, which, as stated before, act as guides for the'blade. At its rear side the bar 10 has a pin 13, against opposite sides of which press adjusting-screws 14, whicheX- tend through the sides of the block. The pin 13 works in a recess 15, formed in the back of the block. By adjusting the screws 14 the bar is turned accordingly and the angle of the file varied as desired. To hold the bar 10 in place in the handle-block 6, a screw 16 is employed, which is tapped through the side of the block into a groove 17 in the turning bar. To hold the file in place in the turning bar and prevent lengthwise movement thereof, clips 18 are secured to the ends of the block and project over the ends of the file. One of these clips can be turned or removed when the file is to be knocked out.
In Fig. 7 a modified form of adjusting device is shown. Instead of the screws 14 for adjusting the file a spring-lever 19 is emloyed. This is located within the recess formed in the top of the casting and is pivoted at one end at 20 therein to swing laterally and has a hole into which the in 13 projects. At the other end the lever as a knob 21, by which the lever may be manipulated, and under this knob the lever has a lug or boss 22, engageable in any one of a series of holes 23, formed in the top of the block. When the lever is swung, the turning bar and the file-holder are thereby turned accordingly to vary the angle. The spring of the lever 19 holds its lug 22 in engagement in the hole 23, in which it is set. Instead of the clips 18, above described, for holding the file in the turning bar the device shown in Fig. 8 may be used. This consists of a metal strip 24, which is inserted in the groove beside the file and is offset at its ends, as at 25, to engage over the ends of the file and is held in place by a sunken screw 26, inserted through the side wall of the groove.
In the use of the device the holder and file are rubbed back and forth along the edge of the blade being sharpened, with the guide edge 8 against the back of the blade and the face of the file against the bevel of the blade, or, conversely, the holder may be held in a vise or otherwise and the blade moved back and forth on the file.
What I claim as new, and desire to secure by Letters Patent, is
1. A file holder comprising a recessed block, a turnable bar held therein and having means to hold the file, and adjusting devices between the block and bar, to set and hold the bar at adjustment.
2. A file-holder com rising a block having a recess and a guide for the work adjacent said recess, a turnable bar held in the recess and having means to hold a file beside the guide, and adjusting devices operatively connected to the bar, to set and hold the same at adjustment.
3. The combination of a file-holder having a guide for the work, and a file held in the holder beside the guide and adjustable therein to vary the angle of its face to the guide,
and means to hold the file as set, at variou angles.
4. The combination of a recessed block having in its face a guide-slot for the WOIk, a file held in the recess with its face exposed in the slot, means to adjust the file to vary the angle of its face with res ect to the edge of the slot, and means to hol the file as adjusted.
5. The combination of a blockhaving a longitudinal bore and a slot extending through the face of the block to the bore, a turning rod in the bore having a groove behind the slot, a file held in the groove with its face eX- posed at the slot, and means to hold the rod at the adjustment desired.
6. The combination of a block having a bore therein and a slot communicating with the bore and extending through the face of the block, a turnable bar fittifig in the bore and having a groove and a projecting pin, a 20 file held in the groove with its face exposed at the slot, and a screw engaging the pin to turn the bar as desired, to vary the angle of the file.
7. The combination of a block, a turnable 25 bar held therein, a file held by the bar, and a screw in the block operatively connected to the bar, to turn the same. i
In testimony whereof I have signed my name to this specification in the presence of 0 tWo subscribing Witnesses.
