IMPROVEMENT IN SAW-SHARPENERS.
Specification forming part 6f Letters Patent No. 175,837. dated April 11, 1876 application 'filed November 17, 1875.
To all whom it may concern Be it known that I, ()RIN MARTIN, of Bloomfield, in the county of Davis and State of Iowa, have invented a Saw-Filing and Setting Machine, of which the following is a specifithe teeth by the automatic stroke of a hammer and a punch upon an adjustable anvil. It consists in an adjustable sliding file-holder,
an adjustable suspended frame carrying the file-holder and driving mechanism, a sliding saw-carrier, and a hammer and anvil being formed, mounted, and combined, upon a portable frame, as hereinafter fully set forth.
Figure 1 of my drawing is a perspective View, giving-a general idea of the construction and operation of my invention.
A is the base of the frame upon which my machinery is mounted. It may be wood or metal, and vary in dimensions to suit machines of different sizes.
B3 are the corner posts on the front side of theframc. U is one of the rear corner posts. D is the driving-wheel journaled to the end of the shaft a, which shaft has its bearing in the frame midway between the posts B. E is a pinion actuated by the driving-wheel D. It is rigidly fixed on the end of the shaft b, which shaft has its bearings in the suspended auxiliary frame that carries the fileholder. c d are corner posts representing the auxiliary, adjustable, sus' pended frame. F is a rock-shaft, operated by an arm extending therefrom to a cam or pin on the driving-wheel, to work the setting device. f f are parallel rails rigidly fixed upon-the frame B G tosupport the sliding sawcarrier G. H represents a saw clamped upon the top of the carrier G. J is the hammer which strikes the punch or setter upon the saw-teeth and anvil. g is a crank-wheel rigidly fixed on the end of the shaft 1), opposite the pinion E, to impart a vertical reciprocating motion to the file-holder and file. K is a rack rigidly fixed to the posts B. It is concentric with the axle a that supports the suspended holder.
frame 0 d, and serves as a means of holding that adiustableframe at various angles. A latch or. set-screw carried by the suspended frame engages the rack Kand locks lhe'frame to the rack.
It can be adjusted in a collar to hold thedifi'erent edges of the file to the saw.
Fig. 2 is a transverse sectional view, givingv details of construction and illustrating the means employed to impart both vertical and lateral motion to the fileholder and file.
The driving-wheel D on the shalt 01v actuates the pinion E on the shaft 1). The crank-wheel g, on the opposite end of. the shaft 12, is connected with the file-holder why a pitmau, n. The file holder m slides vertically in suitable bearings fixed in or on the post d of the suspended frame. L is an adjustablecam-wheel rigidly secured on the shaft 11' by a set-screw,
. to imparta lateral motion to the file. 19 is a lever, bifurcated at its lower end, to engage the cam-wheel L. It is pivoted near its lon- .gitudina'l center to a bearer extendipg from the posts a. At its top it is linked or hinged toan .abjustable collar, r, that-is rigidly secured to the shaft a by a set-screw. The extent of the lateral motion of thefile can be regulated as required for difierent saws by. adjusting the cam-wheel L and coll-arr on their respective shafts b and a. Eachrevolution of the cam L moves the entire suspended frame 0 d, file-holder, and file to and from the saw simultaneously with the action of the crank-wheel g, which imparts a reciprocating vertical motion to the file-holder and file. An automatic movement is thus given to the file very similar to the motions required in filing a saw by hand. i
Fig. 3 is a longitudinal sectional view, illustrating the construction, application, and operation of my setting device.
8 is an adjustable anvil secured in any suit-- able manner, contiguous to the inside rail f, in such a position that the saw-teeth will extend over it as the saw is' moved with the carrier G. t is a punch or setter suspended in a suitable frame over the anvil s. u is a crank or adjustable arm projecting from the rock-shaft F. vis a prop linked or pivoted to the end of the arm u, and reaches up to the helve of the hammer J to lift the hammer.
h is the top handle of the file- A, suitable spring" connected. with the ham mer forces the hammer down to strilievthe setter t when the prop 'u is withdrawn. w is a weighted pawl connected with the sawment of the saw as required for the operation of the file. When the arm 6 projecting from the opposite end of the shaft F" is engagedby the pin projecting from the driving-wheel D;
the shaft F is rocked thereby and the prop v. pushed upward to lift the hammer J, and the.
pitman m is simultaneously pushed'forwardby the arm 3 to move the saw-carrier G" by means of the griping. weighted pawl'w on its front end.
From the descriptionsand'functions of the different parts set forth, it is obvious that a saw may be clamped upon the saw=carrier G and made to pass the anvil and file to have 7 its teeth set andfiled by simply turning'th'e driving-wheel D, and. that the suspended frame' carrying the file may be readily adjustmay be required fordifierenttormsof saw teeth. Each revolution of the'pinion=E 'draws" the file down over the'saw andliftsit away and up again.- The relative diametersofthe each forward motion ofthe. sawmarrierand saw.- When. theJsaw has passed throughthe machine; once" it is turned in the-carrier and 'passedthroughagain to file and set the teeth completely.
carrier G in such a manner as to perform the I claim as my invention- 1.. In a saw-filing machine, the shaft a, carryin'g -the"driving'wheel D; and the adjustable collar 1", in combination with the suspended framec d carryingtheshaft b, pinion E, camwheel' L, pivoted lever p, and crank-wheel g,
substantially as described, to impart vertical and also lateral motion to a file.
2. Thecombinationofthe'sliding file holder him; the pitmah n, crank-wheel g on the shaft :12, and the suspended vibrating frame 0 d, substantially as and for the purposes specified.
V 3. The combinationthesaw oar-rier G, traclvrail's ff; adjustable anvil s; setter t, hammenJ, roek 'shaft F; carrying the-propv-and arms and? e, and: thend'riving wheel 1),
