OHIO, ASSIGNOR OF ONE-HALF TO I WILLIAM ALBERT WHIPPLE, OF ALLEGHENY, PENNSYLVANIA.
MACHINE FOR FILING SAWS.
SPECIFICATION forming part of Letters Patent No. 256,360, dated April 11, 1882.
Application filedJune 13, 1881. (Model) To all whom it may concern: v
Be it known that I, THOMAS MUNOASTER, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Machines for Filing Saws, 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, reference being had to the accompanyin g drawings, and to letters or figures ot' reference marked thereon, which form a part of this specification, and in which Figure 1 is a perspective view of my machine for filingand setting saw-teeth Fig. 2 is a vertical longitudinal section, and Figs. 3, 4, 5, 6, and 7 are detail views thereof.
Thisinventionhasreferencetoimprovements in machines for filing and setting saw-teeth, it being capable of the sundry adjustments to give to the tooth the desired bevel, pitch, or angle, width, depth, and set; and it consists in the combination and arrangement of parts substantially as hereinafter more fully set 'forth.
In the accompanying drawings, A represents a base, to which the several parts of the machine are secured in their proper relation to each other.
B is the anvil-block, to the sides of which are adjustably attached rests B. These rests may be adjusted to any required position for holding the blade of a saw while the teeth are given the desired set or angle of inclination to either side of the saw, and held there bya setscrew, as.
In the upper end of the block B is the anvil O, and the hammer O is hung or pivoted in a recess therein, with its upper portion adapted to overhang the anvil O, and held oft from the anvil by a spring; 0. The tooth of the saw is placed upon the anvil and the hammer struck by a suitable instrument, the blade resting upon the rests B and the head of the screw 1'), which effects the setting of the tooth. By raising and lowering the screwD the saw can be adjusted and the set can be thereby regulated. The screw works in the anvil-block.
The clamp which holds the saw for filing consists, as is usual, of a jaw, d, fixed to the l anvil-block B, and a movable jaw, d, attached to an upright, through which passes a screwthreaded rod, 01 having a thumb-nut, 01 At the other end of the base-board'A' is adjusted betweencleats e 6, so as toslide, a slotted cross-bar, E, with an adjusting screw and nut, e 6 to render it detachable to permit of the removal of the filer, one end of which it supports, for use at other points. the cross-piece E are uprights E, having vertical slots, down through which pass and bear in the said posts or uprights screws E provided at their upper ends with operating thumb-pieces 6 secured rigidly to the screws. With its ends threaded upon the screws E is a cross-rod, F, upon which is fitted so as to slide a block, f, carrying a disk, f, which is slotted so as to receive a sliding bar, G. By this construction the disk f, providing a hearing for-the sliding bar G, may lie-adjusted up or down, as desired, by turning the thumbpieces 0 In the diskf' are segmental slotsf,through At the ends of which pass screw-rods g, anchored in the block 5 f. -A disk,f, of thin metal, rests upon the disk f, covering the slot for the bar G and the segmental grooves, and through this disk f the screw-rods, having passed through the grooves, pass up through the disk f and receive thumb-nuts g, by means of which the disk f is held down rigid upon the disk f, clamping both disks to the block fupon the completion of the circular adjustment of the disk f to secure the desired angle of presentation of the bar G, and through it the file which it carries.
G is the file holder, which is swiveled into the forward end of the bar G to permit it to turn independently of the bar or slide, and hasarack,g ,with which engagesaspring-pawl, 9 to hold the holder G at the desired point of rotation, and thus enable the file to be so presented to the tooth as to regulate the degree of inclination or bevel it is desired to impart to the tooth. This adjustment, it will thus .be seen, permits of varying the size of the tooth, if it is desired to enlarge it, or cut from the 'start a small or, large tooth upon a new blade.
The file-holder is suitably slotted, and provided with a holding-screw, h, to secure the file fixedly thereto. A frame, H, of the shape of the file, with a solid upper piece, provided with a screw, i, is placed upon the file, the screw securing it thereon.
H is a second frame, with its arms provided with slots j,whioh, by means of nutted screws j, fixed to the frame H, permit of the horizontal lateral adjustment of the frame H. The arms of the frame H are bent down to conform to the inclination of the side of the file, and have attached to them by nutted screws 7." a gage-plate, H adapted by the addition of slots k to be vertically adjustable.
From the foregoing adjustment of the frame B it will be noticed that the plate H can be moved laterally, or so as to enter the throat of the adjoining tooth, and thus allow the file to be adjusted so as to cut the blade at a greater or less distance from the point of the already formed or adjacent tooth to permit of making a tooth or teeth of different width. The vertical adjustment of the plate H per mits the dept-h of filing of the teeth to be regulated.
The platef upon the disk f may be graduated to any desired scale of measurement to readily determine the degree or amount of pitch it may be desired to impart to the teeth.
The file can be readily removed for filing other work.
This machine does its work with certainty to the fraction of an inch,and can be operated without the exercise of skill, though performing the work skillfully.
Having thus fully described my invention, I claim and desire to secure by Letters Patent- 1. The file-holding frame H and set-screw i, in combination with a slotted laterally-adjustable frame, H, having secured thereto the adjustable gage-plate H substantially as shown and described.
2. The cross-rod F, block f, disk f, having curved slots f, disk f, and nutted screws 9 g, fixed with relation to the disks, in combination with the file-holder bar G, substantially as and for the purpose set forth.
3. The combination, in a saw-filing machine,
of the base A, cross-bar E, uprights E, thumb piece 6, screws E block f, cross-rod F, and disks f f", for receiving the sliding bar G,
substantially as shown and described.
In testimony whercofI aflix my signature in presence of two witnesses.
THOS: MUNOASTER. Witnesses:
