BENJAMIN B. SMITH, OF GADSDEN, ALABAMA.
SAW-SWAG IE.
SPECIFICATION forming part of Letters Patent No. 747,094, dated December 15, 1903.
Application filed May 5,1903- Serial No. 155,750. (No model.)
To all whom, it may concern:
Be it known that I, BENJAMIN B. SMITH, a citizen of the United States, residing at Gadsden, in the county of Etowah and State of Alabama, have invented certain new and use ful Improvements in Saw-SwageS; 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 improvements in saw-swages, and particularly to the adjusting mechanism of the anvil thereof.
The object in view is the provision of means for facilitating the adjustment of the anvil to a nicety at any given angle and at any desired point.
With this and other objects in view the invention consists in combination, with a block and operating mechanism, of an anvil carried thereby and bodily movable and means for swinging said anvil to various points.
It further consists in certain other novel construction, combination, and arrangement of parts,as will be hereinafter fully described and claimed.
In the accompanying drawings, Figure 1 represents a view in side elevation of a sawswage embodying the features of the present invention. Fig. 2 represents a top planview of the same. Fig. 3 represents a vertical central section taken on the plane of line 3 3 of Fig. 2, parts being shown in elevation. Fig. 4 represents a similar view taken on the plane of line 4 4 of Fig. 2. Fig. 5 represents an enlarged detail perspective view of a swaging-die.
In the artto which the p'resentinventionrelates it is found desirableto provide an anvil notonly capable of bodily adjustment but also capable of a pivotal or swinging movement for positioning the point thereof to a nicety relative to the tooth to be swaged. A swaging-die is ordinarily employed in conjunction with the anvil, and in order to'accomplish the desirable result above mentioned and to prolong the life of the swaging-die I provide, as seen in the accompanying drawings, a block 1, formed with a central segmental aperture or cut-away portion 2, leaving an arc-shaped strip 3, which strip is formed with alongitudinal slot 4.. Bodily movable within the slot 4 and extending through the same is a bolt 5, forming an anvil and having its lower end beveled, as at 6, conforming to the shape of a tooth'of a saw. The bolt 5 is retained in position by head-blocks 6. 6, surrounding said bolt and extending beyond the edges of slot 4, and locking-nuts 7 7, threaded onto said bolt outside the blocks 6. The blocks and bolts just described are arranged, respectively, above and below the strip 3 and are designed to clamp the same for retaining the bolt 5 in position. It is, therefore obvious that either of the nuts 7 may be loosened and the bolt 5 moved bodily within the slot 4; but in order to facilitate a nicety of adjustment of the lower end of said anvilbelt I contemplate providing a series of setscrews 8 8, extending through each end of each block 6 and engaging the face of the strip 3, whereby the loosening of said setscrews and tightening of others will rock or swing the anvil-bolt pivotally.
An arm 9 projects from the block 1 and carries any suitable gage 10 for retaining the block in its proper position relative to the saw being swaged.
Theblock l is formed with a comparatively 7 deep groove 1 1,'cut in its under edge, extending to the cut-away portion 2 for receiving a saw, as 12, whose teeth are to be swaged. A clamping member 13 extends through said block l, and a clamping-bolt 14 is threaded through the said block opposite said clamping member for engaging the saw 12 and locking the same in position against the clamping member when the bolt 14 is rotated. A suitable handle 15 is provided for rotating the bolt 14;. Rotatably in and extending through the block 1 slightlyto oneside of the swaging end of anvil-bolt 5 is aswaging-die 16. The die 16 is made up of a shaft threaded at each end, as at 17 17, and provided centrally with a swaging-cam, which comprises simply an oval formation of the shaft in transverse section, as at 18. (Best seen in Fig. 3.) Between the cam 18 and the ends 17 are formed locking annular grooves 19 19, in operation designed to be engaged by a locking-slide 20 for retaining the swaging die against longitudinal movement, the said slide 20 being formed with a longitudinal slot 21, through which passes a supporting-pin 22, extending into the block 1,
said pin being threaded into said block for locking the slide in any given position.
In operation a saw-blade is locked within the groove 11 by means of locking-bolt 14, one of the teeth of said blade extending between the cam 18 of the swaging-die and the lower end of the anvil-bolt 5, whereby rotation of said die will press the end of said tooth against said anvil and mash said tooth into the desired shape. The die 16 is designed to be actuated by any suitable handle 23, threaded onto either end 17, said die being reversiblethat is, susceptible of being used with one face of the cam 18 in operative relation to the anvil 5, and removed, turned end for end, and replaced in position for employing the opposite face of said cam, whereby the length of life of the die is doubled. It will be observed that the slide 20 may be caused to engage either of the grooves 19 for locking the said die againstlongitudinal movement. It will thus be observed that when one portion of one face of cam 18 has become worn the slide 20 may be removed, the die 16 adjusted longitudinally, and the slide 20 caused to engage in a new groove 19 for retaining such die in its given position, a new portion of the cam-face being thereby exposed for action.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a saw-swage, the combination with a block and operating mechanism, said block provided with a transverse aperture forming a strip upon said block, said strip having a slot therein and an anvil provided with locking-nuts adjustably secured in said slot.
2. In a saw-swage, the combination with a block and operating mechanism, said block provided with a slotted strip formed integral therewith and an anvil adjustably secured within said slot by means engaging the inner and outer surfaces of said strip.
3. In a saw-swage the combination with a 'block, an operating mechanism, of a curved ing the inner and outer surfaces of said strip upon said block and means for vertically adjusting said anvil when in an unlocked position.
5. In a device of the character described the combination of a block, an operating mechanism therefor, a strip extending across said block and formed integral therewith having a slot formed therein, an anvil mounted upon said strip within said slot, said anvil provided with head-blocks, and said headblocks carrying means for adjustably retaining the said anvil upon the block.
6. In a device of the character described the combination with a block and an operating mechanism therefor, of a curved strip formed integral with said block, said strip having an aperture formed therein, and an anvil mounted within .the aperture, headblocks carried by said anvil and adjustable axially thereon and provided with adjustingscrews for adjusting the anvil and means carried by said anvil for retaining the headblocks in adjusted position.
7. In a device of the character described, the combination with a block and an operating mechanism therefor, of a curved strip extending across and formed integral with said block and an aperture formed in said strip, an anvil removably secured within said aperture and provided with means for engaging the concave and convex surfaces of said strip and means removably secured upon said means carried by the anvil for retaining the said anvil in a predetermined position.
8. In a device of the character described, the combination with a block and operating mechanism therefor, of a curved strip formed integral with said block and having an aperture therein, a removable anvil retained within said aperture and provided with headblocks axially adjustable thereon and having concave and convex surfaces, a series of adjustable screws retained upon said headblocks and adapted to swing the said anvil upon the strip, and nuts carried by the anvil and bearing upon the head-blocks for looking the same in a fixed position upon said strip.
In testimony whereof I hereunto affix my signature in presence of two witnesses.
. BENJAMIN R. SMITH.
