SAW-SET.

SPECIFICATION forming part of Letters Patent No. 751,849, dated February 9, 1904.

Application iile June 30, 1902. Serial No. 113,787. (No model.)

T all whom, t may concern.-

Be it known that I, SAMUEL HALTOM, a citi- Zen of the United States, residing at Henderson, in the county of Rusk and State of Texas, have invented a new and useful Saw-Set, of which the following is a specification.

This invention relates to saw-sets, and is design ed to automatically feed the saw-blade and set the teeth, regardless of the size thereof, in a simple and effective manner and to provide for a continuous uninterrupted operation of the device as fast as the controlling means can be manipulated. It is furthermore designed to have the setting-punch accomplish the feeding' of the saw-blade, thereby to dispense with independent saw-feeding mechanism, and hence to materially simplify the construction and operation of the device, and also to provide for adjusting the movement of the punch so as to accommodate the same to sawteeth of different sizes in order that the sawblade may be properly fed the required distance to set the proper teeth and to avoid skipping of any of the teeth.

Another object is to provide an improved saw holder and 'guide to prevent looseness and yielding' of the saw-blade under the action of the setting-punch and to have the guide adjustable, so as to accommodate saw-blades of different widths, and also to provide for adjustably tilting the saw-blades, so as to secure any desired degree of set or angular displacement of the teeth.

A final object is to have the device applicable to wide handsaws, as well as to the narrow blades of butchers7 and band saws, and to provide a supplemental guide for application to wide saw-blades and for cooperation with the saw-guide carried by the frame of the device.

'Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings, and particularly pointed out in the appended claims, it beingl understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

Fig'. 12- is an enlarged detail sectional view taken longitudinally through the anvil and the saw-guide to illustrate the manner of guiding a wide handsaw-blade. Fig. 13 is a similar view showing the saw-blade reversed to set the teeth at the opposite side. Figs. 14

,and 15 are detail views of the supplemental 4to a suitable distance above the body of the frame and has a forward extension 5, projected in advance of the body and having a pendent arm 6. At the front of the main bar 1 of the frame is an integral laterally-projected anvil portion 7, the top of which is iiush with the top of' the bar 1, and its front is beveled downwardly and rearwardly, as clearly indicated in Figs. 2, ,12, and 13. The top of the anvil is provided with an openended groove or seat 8, which deepens toward its forward end for the accommodation of the setting punch, as will be hereinafter eX- plained. At the front of the anvil is an in- IOO tegral downwardly and forwardly inclined and longitudinally-bifurcated platform 9, the bifurcation of which communicates with the groove or seat 8.A

The combined punch and feeder, which is constructed, as hereinafter explained, to feed the saw and set the teeth thereof and which is successively moved to accomplish these results, is designated by the numeral and eX- tends from the anvil to the rear of the arm 4, where it is supported in a seat 11, projected laterally from the arm 4 and held thereto by means of a headed fastening 12, .passing through a longitudinal slot 13 in the punch and entering the seat, whereby the punch is capable of an endwise-reciprocatory movement. At the rear end of the punch there is a lateral outwardly-directed heel or shoulder 14, which bears against a helical spring 15, interposed between the part 14 and the rear end of the seat and received within a socket or recess 16, formed therein. The fastening 12 besides forming a guide for the punch in its endwise movement also forms a pivot therefor to permit lateral swinging of the punch, and the spring 15 is designed to return the punch to its normal position after each opera- A tion thereof-that is to say, the spring pushes tween two adjacent teeth, as clearly indicated in Fig. 7 of the drawings, so that when the punch is shifted laterally the projection 18 will operate to feed the saw-blade in an endwise direction. At about the middle of the punch there is an upstanding cam-ange 19, (best illustrated in Fig. 5,) with its outer face beveled or inclined upwardly and inwardly and designed for shifting the punch laterally, as will be hereinafter described. In front of the cam-flange 19 and projected laterally from the opposite side of the punch is a cam-shoulder 20, which is carried by the punch and has its rear face inclined upwardly and forwardly and also laterally inward, this cam or flange projection being adapted to feed the punch forward. Moreover, the cam-flange 2O is provided at its outer end with a pendent lug or shoulder 21, which normally rests upon the anvil, so as to support the punch in an elevated position, and when the punch is shifted laterally the projection clears the anvil, so as to drop down at 'the outer side thereof when the punlh is forced downwardly to bend or set a toot The means for reciprocating and swinging the punch both horizontally and vertically consists of a vertically-reciprocating trip-slide 22 for coperation with the cam portions of the punch and a manipulating-lever 23, fulcrumed upon the main frame and connected to the slide. The slide 22 has its upper end working through a slotted guide projection 24, carried by the upper portion of the frame, and is provided at its outer side with a pendent pin o1' stem 25, which works through a perforate guide projection 26, carried by the lower end of the frame extension 3. A helical spring 27 embraces the stem and bears in j opposite directions against the projection 26 and apin 28, set transversely through the upper end of the stem. The purpose of the spring 27 is to return the slide to its normally elevated position after being depressed by the lever. The lever is fulcrumed intermediate of its ends upon the pendent frame extension 3,.as indicated at 29, and has its forward end pivotally connected to a link 30, which is pivotally hung from the inner side of the slide 22. The slide 22 is in the form of a flat metallic plate having an opening for the reception of the punch, the upper edge 31 of the opening, as best shown in Fig. 5, being inclined upwardly and inwardly to form a cam for coperation with the cam 19 of the punch to shift the latter laterally inward when the cam 31 rides over and downwardly across the cam 19. It will be noted that the length of the opening in the slide is greater than the combined thickness of the punch and the cam 19, so that the slide may have a considerable initial movement before the cams 31 and 19 engage in order that the punch may be moved forvtrdly to its limit before it is shifted latera y.

For moving the punch forwardly before it is shifted laterally a cam projection 32, as best shown in Figs. 3 and 4, is provided upon the front side of the slide 22, near the inner edge thereof, the under side of the cam projection being inclined upwardly and forwardly, so as to cooperate with the laterally-projected cam 20, carried by the punch, whereby as the cam 32 rides -downwardly 'across the cam 20 the punch will be moved forwardly in an endwise direction, so as to engage the feed projection 18 of the punch between a pair of teeth of thesaw, the cam 32 being located below the lower end of the cam 31, so as to move the punch forwardly before it is shifted laterally. As best indicated in Fig. 4, it will be seen that the rear side 33 of the cam 2O is beveled or inclined from its outer end toward its inner end in order that there may be no binding between the cams 32 and 20 when the punch is shifted laterally.

By reference to Fig. 5 it will be observed that the lateral movement of the punch isA limited by engagement with the wall 34 at the upper end of the cam 31, which forms a IOO IOS

l'IO

stop-shoulder, and when this point has been reached the punch is moved downwardly by the further downward movement of the slide 22, it of course being understood that the connection between the punch and the fastening' l2 is sufliciently loose to permit of these movements in three different directions. rlhe downward movement of the punch is limited by reason of its engagement with the anvil, and when the lever 23 is released the slide will be automaticallyT elevated by the spring 27, thereby elevating the punch, and the latter is also moved rearwardly and shifted laterally outward into its original normal position under the action of the spring l5, which has been compressed by the operation of the punch. rlhe upward movement of the slide 1s limited by means of a stop-shoulder 34a, provided upon the outer edge of the slide and disposed to strike against the under side of the outer end of the guide 24, so as to prevent the upward displacement of the slide and to stop the latter in proper position for engagement with the punch. From this description it is apparent that the punch can be operated as fast as the lever can be manipulated, and therefore the device may be operated as fast or slow as may be desired by manipulating the lever 23 accordingly.

In order that the punch may have a free upand-down swinging movement, it is preferred to pivotally mount the seat ll, as best illustrated in Fig. 4, by providing the seat with a pivot-pin 36, which pierces the arm 4 andis held against endwise displacement by means of a ltey 36, which is passed transversely through the outer end of the pivot-pin and lies in a socket or depression 37 in the latter face of the arm 4, whereby the latter is free from projections.

rlhe lateral inward movement of the punch is limited by having the projection 1S drop into the groove or seat 8 in the anvil 7, which stops the punch in the proper position for engaging the setting-point 17 with the tooth to be bent or set. To limit the lateral movement in the opposite direction, there is provided a stop in the form of a set-screw 38, which pierces a post 39, rising from the outer end of the anvil, the set-screw being adjustable through the post to vary the outward movement of the punch. rlhis adjustable stop 3S is a very important feature of the present invention, as it provides for regulating the length of the lateral throw of the punch, so as to accommodate the latter to saw-teeth of different sizes, and therefore renders the present device capable of a wide range of usefulness upon saws of different sizes.

It will be understood that a saw-blade is adapted to be supported upon the inclined platform 9, as indicated at 40 in Figs. l and 2 of the drawings and by dotted lines in Fig. 4, with the teeth projected above and inclined across the front of the anvil, so as to be in position to be bent down thereagainst by the setting-point of the punch.

To hold the saw-blade against the platform or support, there is a holder consisting of a pendent arm 4l, adjustably hung from the outer endof the upper part 5 of the frame by means of a thumb-screw 42, the opening 43 in the arm, as shown in Fig. 9, being considerably larger' in diameter than the screw, so as to afford an adjustment of the arm, the latter having' a laterally-projected holding or presser foot 44, carried by its lower end and lying over the platform or support 9. rlhis foot is provided with a longitudinal slot 45, and at the inner side of the slot is a springfinger 46, having its outer end connected to the upper side of the foot and its rear free end provided with a pendent projection 47, lying in a notch 48 in the rear edge of the foot and of a length to lie against the blade, so as to press the latter into engagement with the support or platform.

The saw-blade is guided in its endwise feeding movement and is held` against outward edgewise displacement Linder the action of the setting operation of the punch by means of a guide consisting of a plate 49, disposed transversely across the top ofthe support or platform 9 and provided with a plurality of upstanding pins 50, which have polygonal Shanks and have screw-threaded connections with the plate, so as to be detachable therefrom. The outer pins lie at the outer edges of the support or platform 9, while the center pin is accommodated in the bifurcation of the platform and the slot of the presser-foot, whereby the plate may be adjusted without interference by the presser-foot. The under side of the plate is provided with a central head 5l, which is projected in rear of the plate, and is provided at opposite sides with longitudinal flanges 52, that iit in longitudinal grooves or guideways 53 in the opposite edges of the bifurcated portion of the platform or support 9, so that the guide-plate may be adjusted toward and away from the setting-punch. The rear end of the head is provided with a pendenteXtcrnallyscrew-threaded tubular stem 54, which projects through the bifurcation of the platform or support 9 and carries a wrench-nut 55 to clamp against the under side of the platform and hold the guide-plate at any adjusted position, there being a washer 56 interposed between the wrench-nut and the platform. rlhe interior or bore of the stem is screw-threaded and extends through the top of the head, and in this screw-threaded bore is fitted an adjustable set-screw 51, which is adapted to be projected upwardly beyond the face of the guide-plate, so as to engage the under side of a saw-blade to adjustably tilt the latter, as shown in Fig'slZ and 13, to vary the inclination of the set of the teeth.

It is of course desirable to accurately adjust the saw-blade, so that each tooth may project IOO IIO

across Vor overhang the anvil at a predetermined distance-that is to say, for exactly the length of the tooth-and to obtain this feature of adjustment I provide two gages 58 and 59, which have been shown in detail in Fig. 11. The gage 58 is in the form of a right-angle clip, having one member disposed transversely across the anvil and its other member lying against the outside of the post 39 and provided with a slot 60 to receive the set-screw 38, whereby the gage may be adjusted toward and away from the front edge of the anvil, there being a wrench-nut 61 applied to the setscrew 38, so as to lock the latter and also secure the gage when these parts have been adjusted. of a right-angled clip, one member of which projects across the upper face of the anvil and is cut away longitudinally upon its outer face and at its lower edge, as indicated at 62,to form a seat for the reception of the outer ends of the saw-teeth, the other pendent member of the clip being provided with a transverse slot 63 to receive a fastening 64, the latter being best shown in Fig. 3 and serving to adjustably connect the gage to the frame of the device.

In the operation of the device to set the teeth of a narrow saw-blade, as best illustrated in Figsfi, 6, and 7, the saw-blade 40 is thrust endwise between the support or platform 9 and the presser-foot 44:, with its back edge lying against the pins 50 of the guide, the latter then being adjusted forwardly until the base of the teeth are alined with the straight front edge of the anvil 7, and then the handled nut 55 is tightened, so as to hold the guide, and the thumbscrew 12 is tightened to hold the spring of the presser-foot in engagement with the upper side of the saw-blade, so as to prevent displacement thereof. The gages 58 and 59 are then adjusted so as to lie against the points of the teeth, but not so tight as to interfere with the endwise shifting or feeding of the blade. The blade thus being in position, the palm of the hand will be placed against the handle 2, and the lingers of the hand are pressed upwardly against the rear end of the lever, so as to draw the punch-controlling slide 22 downwardly to actuate the punch. rlhe lever is at first moved very slowly, so as to impart only the initial endwise movement to the punch in order that the saw-blade may be adjusted by hand in an endwise direction to receive the feed projection 18 accurately between a pair of teeth and in rear of the iirst tooth to be set. After this adjustment has been accomplished the device is then ready for operation, the handle being regularly manipulated as fast as desired, and

the teeth will be regularly bent or set and the saw-blade properly fed or shifted without further attention to either the saw or the machine. As hereinbefore explained, the initial forward movement of the punch places the feeding or shifting projection 18 in the space between a The other gage 59 is also in the formpair of teeth at the outer side of the groove or seat 8 in the anvil, the lateral swinging movement of the punch feeds or shifts the sawblade in an endwise direction, so as to move the tooth below the setting-point 17 to the opposite side of the seat 8, and then the downwardmovement of the punch brings the setting-point into engagement with the tooth, so as to bend the same down against the anvil. It will be noted that these three distinct movements or operations of the setting-punch are brought about by one manipulation of the lever, and when the latter is released the spring 27 automatically returns the lever to its original position, and through the medium of the slide 22 and the spring 15 the setting-punch is returned to its original position in readiness for another operation, whereby it is apparent that the teeth may be readily and conveniently7 set without any additional adjustment of the parts and merely by a continued manipulation of the operating-lever. It will of course be understood that the stop 38 is adjusted to limit the outward throw of the punch so as to travel backward from its fin-al position the distance of one, two, or more teeth, according to the character of the saw or the desire of the operator, in order that the teeth may be set in regular order, and after the stop has once been adjusted the feed of the saw-blade will be absolutely perfect, and there will be no irregular setting of the teeth. After the sawblade has been passed entirely through the machine it is inverted and passed through again, so as to set the alternate teeth at the opposite side of the saw-blade, this second operation being accomplished Without further adjustment of any of the parts of the device.

It will here be noted that the saw-guide formed by the plate L19 and the pins 50 accurately guide the saw-blade in its movement across the device and also prevent edgewise displacement of the blade under the action of the forward movement of the punch and also under the setting action thereof. Moreover, the blade is held Jiirmly against tilting under the bending or setting action of the punch by IOO IIO

the presser-foot 44:, and therefore all of the p teeth are bent from the same point and also set at the same angle.

When it is desired to set the teeth of a sawblade which is too wide to t between the gages 58 and 59 and the pins 50 of the guide-plateas, for instance, a handsaw-the pins 50 are removed from the guide-plate, and, as shown in Fig. V12, the saw-blade 65 is placed between the support or platform 9 and the presser-foot 44 and also over the guide-plate 49. To prevent the saw-bladefrom being displaced under the action of the punch, there is provided a supplemental guide-rod 66, which is angular or substantially L shape in cross-section. This guide-rod is applied to the under face of the saw-blade in rear of the teeth and is of a length to project at opposite ends of the saw-blade,

it being held thereon by means of terminal clamps, each of which consists of a set-screw 67, which pierces the rod and also pierces a clamp member 68 at the opposite side of the saw. Each set-screw pierces the guide-rod adjacent to but beyond the end of the sawblade, the screw at the forward end of the rod being fitted in a longitudinal slot 69, s"o that the clamp may be adjusted longitudinally upon the rod to iit saws of different lengths. Moreover, the outer end of each clamp member 68 is provided with a transverse shoulder 70 to bear against the rod, while the opposite inner end of the clamp member lies against the saw-blade, whereby an effective clamping action is had between the member 68 and the blade. Then the saw,with the guide thereon, is applied to the saw-set, the flange 7l of the rod bears against the inner edge of the guideplatc 49, whereby the saw is held against outward edgewise displacement and is eifectively guided in its endwise movement. After one set of teeth has been bent or set the saw-blade is inverted, as in Fig. 13, so as to bring the guide-rod upon the upper side of the saw. The guide is then adjusted nearer the toothed edge of the saw, so that its flange 7l may engage the inner or rear edge of the presser-foot 44, which latter then forms a stationary guide for cooperation with the guide-flange 7l. It will here be noted that the inclination of the sawblade may be conveniently varied by means of the adjusting-screw 57, so as to vary the set of the saw-teeth.

The saw-set is adapted to be used either as a hand-tool or to be mounted upon a bench or table, and when arranged upon such a support any suitable means may be employed for actuating the operating-lever.

Then the saw-set is used as a hand-tool, it will feed itself automatically along a saw-blade, as will be readily understood, and when the saw-set is used as a machine the saw-blade will be automatically fed forward.
