The arbor is supported in the bearing 23 at the top of the support H and secured therein by a cap 23 secured to the bearing by screws.
A tool 24 is mounted on a carrier therefor to have reciprocatory movement toward and away from the work on the work support, said tool carrier including a post 25 having a head 26 at one end arranged with a dovetail slideway 25 extending longitudinally of the face thereof opposite the post, and a slide 21 carrying the tool 24 centrally thereof is arranged with a portion conforming to and slidably engaging in the dovetail recess in the head. The slide is adjusted longitudinally of the head by a spindle 29 having a crank connected thereto and rotatably mounted in the head 21 and having threaded connection intermediate the ends thereof with a perforated ear 3!! extended downwardly from the bottom of the head 26 and engaging in a longitudinal recess 3| in the slide 21, as shown in dotted lines in Figure 5.
, To support and longitudinally reciprocate the tool carrier the post is connected at the end opposite the head 26 to one arm of a lever 32. by a link 33 pivotally mounted on a pin extending between and fixed at the ends in arms 23' extending upwardly from the tubular support 23 at diametrically opposite sides thereof, The opposite end of the link 33 is provided with a globular member 34 adapted to be seated in a socket in the end of the tool post 25 the end wall of which is in an arc of a circle having a radius the same or slightly longer than the radius of the globular member 34, the globular member being, retained in said socket and thereby the post connected to the link by a tubular member 35 threaded into the socket, the end of said member 35 engaged in the socket being arranged of arcuate form to conform to the curvature of the globular member and engaged therewith to hold it to its arcuate seat in the end of the socket, as shown in Figures and 6 and having an annular laterally extending flange at the opposite end arranged for the engagement of a manipulating member to screw said tubular member into the socket in the post. The lever 33 is rocked to reciprocate the tool carrier from an eccentric 36 having a tapered stem 36 arranged axially of and extended laterally therefrom engaged in a tapered bore in a shaft S rotatably supported at one end in a bearing in the standard H of the frame, said shaft having a pulley 3i fixed thereon for the engagement of a belt 38 to rotate the pulley and thereby the shaft from a suitable source of power.
The lever 32 is rocked from the eccentric 36 by a link or pitman 39 having a semi-circular portion 39 at the end engaging a peripheral portion of the eccentric and connected in operative connection with the eccentric by a semicircular strap 40 engaging the periphery of the eccentric'opposite to and connected to the circular portion 39' of the pitman. The opposite end of the pitman is connected to a bifurcation at the end of the lever 32 opposite the tool carrying post 25 to have universal movement relative to the lever by a pin 4| extended through a transverse opening in a globular portion 42 at said end of the pitman and supported at the opposite ends in the bifurcation legs of the lever arm, the opposite faces of which bifurcation legs are provided with arcuate recesses conforming to the curvature of the globular portion 42, and the opening in said globular portion being of progressively increasing diameter from midway the ends to the outer surface of said globular portion, as shown in Figure 4, to permit of slight rotative movement of the pitman relative to the axis of pin 4i. The pitman has an enlarged portion 39 intermediate the ends having an opening therein for the passage of the supporting arbor 2| for the tubular support 20.
The tool carrying post 25 extends through and is reciprocated in the tubular support 23 toward and away from the work support through its connection with the lever 32 and the actuation of the latter from the eccentric 36, and means adjustably carried in the tubular support is adapted to 'be engaged by and guide the tool carrier to cause it to reciprocate axially of the tubular support 20 and perpendicular to the work support and the tool to pass through an opening in the work or die plate and produce cuts extending at a right angle to the face of the work, or to be reciprocated in different or varying planes oblique to the perpendicular and the axis of the tubular support to cause the tool as it passes through the work or die plate to move progressively laterally and produce diagonal cuts by the tool, and to vary the extent of such lateral movement of the tool to vary the angle of cut by the tool; and to rotatably adjust the tool carrier to change the direction of reciprocation thereof and lateral movement of the tool. For this purpose a sleeve 43 is mounted in the tubular support 20 to have rotative adjustment and held against endwise movement by an annular flange at one end of the-sleeve, shown as the lower end, engaging a shoulder formed by an enlargement of the bore in the tubular support, as at 44, and the'sleeve supported and held to said shoulder by a collar 45 engaged on the sleeve 43 and secured thereon in abutting relation to the end of the tubular support 20 by a set screw.
A guide member in the form of a second sleeve of less diameter than the internal diameter of the sleeve 43, in which the tool carrying post 25 is slidably engaged, is supported at one end in one end of the sleeve 43, in the present instance the lower end, by a self-alining bearing of the ball bearing type 41, whereby the guide member is adapted to be positioned to extend axially of the sleeve 43 and tubular support and to be tilted to extend at different angles inclining to the axis of the sleeve 43. The outer ring of the bearing is secured in an annular enlargement at the end of the bore in the sleeve 43 and has an arcuate inner ball engaging surface 41 arranged in an arc of a circle whose center lies in the axis of the sleeve 43, and the inner ring of the bearing is secured on the reduced end of the guide member and is provided with an annular ball engaging raceway intermediate the ends of arcuate form in cross section concentric of the balls.
The guide member or sleeve 43 is supported at the opposite end by a self-alining bearing of the ball bearing type 48, the outer ring of which bearing is mounted in a slide 49 slidably carried by the sleeve 43 to have adjustment transversely thereof, the inner ball engaging surface 48' of which ring is also in an arc of a circle whose center lies in the axis of the sleeve 43, and the inner ring is secured on the reduced end of the guide member and has an annular ball engaging raceway intermediate the ends of arcuate form in cross section concentric of the a cent balls. The slide 69 is slid'ably mounted a slideway 50 in a member llg the sl-ideway having dovetail portions engaged by correspondingly shaped portions of the slide. The member 5|; is arranged: with a laterally extending annular flange 5!" whereby it is mounted upon the reduced end oi the sleeve 43 with the slideway extending transversely oi the end oi said sleeve and secured thereto; as by a setscrew or other.- wise. To adjust thesl-icl'e and retain it in ade justed position a spindle 52 having a crankor hand wheel connected thereto is rotatably sup, ported in a flange 54 extended upwardly item the member 51 at one end otthe slideway therein, the stem having screw threaded connection with the slide 49, asshown in Figures 1, 3 and 6, whereby when the stem is rotated in one direc tion the slide is adjusted in one direction and whenthe stem is rotated in the oppositedirection the slide is adjusted in the opposite direction. Assuming the slide has beenadjusted to position the guide member 46- and tool carrying post to' extend axially or the sleeve and perpendicular to thework support, as shown in Figure 5; The tool carrying slide 2-1 insuch position of the parts is then adjusted toposition the tool relativ to an opening in the die plate and as the tool carrier is reciprccated the tool 24 wiilproducecuts at ar-igh-t angle tothe face of the work or die plate. To cut a wall extending longitudinally of the die plate the slide 16 of the work support is adjusted with the work longitudinally of thema-chi'ne by rotating the crank: 29', and to cut a slot wall extending transversely of the die plate the bed [2 with the slide a line extending perpendicular to the work sup port, as shown in Figure 6, and such adjustment of the guide member is in accordance with the desired angle of the cut to be produced by the tool.
To change the direction oicut-by the tool", as in cutting the corners of" a rectangular opening in a die plate; or to provide the slot with an arcuate wall portion, the sleeve 4% with the guide member 46 and tool carrier is adjusted about its axis in the tubular support 20; and such-'ad-.
justmen-t of the sleeve 43 indicated by the relationof g-raduations onthe beveled end portion: 53 of the sleeve 43 relative to an indicator line 54 (Figure 2) on the; end of the tubular support 2|].
To impart rotative movement to the sleeve 43 it is provided with the worm wheel 5 5,shown as arranged on the annular flange 5|" of; the member 5| having the slideway The worm wheel isrota-tedby a worm; 56* rotatably supported in a bracket 51 mounted on a pinsupported in cars 5 8- extended from the tubular support 20 said worm, ori' ihe shaft on which the worm is arranged ormounted being provided with a crank 56 to rotate the same. The worm and worm gear are adapted; for eiiecting fine adjustment ofthe tubular support 2-0- with theguidemember 46 and tool carrier carriedthereby. To permit of adjustment ofthe. sleeve 4'3 by hand independently" of said worm and worm wheel the:
worm carrying bracket- 51 is. pivotally supported by thenears 53' whereby the. worm is. adapted to be moved into and out of mesh with the worm wheel; The: bracket is: secured in position with the worm in mesh with the worm wheel by astem 5% having aknurledhead extended: through an opening in the bracket withan annular enlargement. 55 on the stem abutting the. bracket and adapted to have screw threaded connectionwith an opening in the tubular support. Eli, as shown in- Figure l. a
a To couple the tool carrier- With the. sleevevv 43 to. participate in: the rotative movement of: the sleeve and. permit of reciprocatory movement of the tool carrier, guide plates are extended downwardly from: the: lower end of the: sleeve. 43 at opposite sides of the head 26 and the tool carrying slidefl carried by said head. The guide plates 60 may be integral with the sleeve 43, but are preferably constructed independently of said sleeve and attached thereto, as by screwszfiit. By the arrangement of the: ball and socket connection 34 betweenthe tool. carrying post 25 and its supporting link 32 said post is. adapted to participate in the rotativeadjustment of the sleeve 43" and guide member 4.6 without interfering with the reciprocatory' movement of the tool carrier.
The tubular support 20; is'longitudinallysplit to facilitate mounting the sleeve 43 therein, which is efiected by loosening the screws 52 en.- gagin-g perforations in cars: 63 extended laterally from the tubular support 20 and having threaded connection with openings: in ears 64 also. ex-
tended laterally from said: tubular support. Atter the sleeve 43 has been engaged in the: tubular support 20 the split-ends. of the tubular support are drawn together by thesc-rews 62.
Ii. will be: obvious that various modifications may be made in the constructionand arrange.- ment of the parts without departing. from the scope of the invention and that; portions. of the invention may be used without others and come within the scope of the invention.
