CHARLES E. VANCE, O'F TULSA, OKLAHOMA.
GASKET CUTTER.
Application filed May 19, 192,2, Serial No. 562,138.
T0 all 'whom t may concern.'
Be it known that I, CHARLES E. VANcE, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Gasket Cutters, of which the following is a specification.
This invention is for a gasket cutting device, and has for its primary object to provide a device for this purpose which is relatively simple and durable and which may be cheaply constructed and easily operated.
Further important objects of the invention are to provide a cutter which may be used to cut circular or oval gaskets and which has adjustable cutting knives of improved construction.
In my co-pending application Serial No. 430,612 of December 14,v 1920, I show a gasket cutter of a heavier type carried in a supporting` frame in such manner that it may be moved about to cut from different parts of a sheet of material. The present invention, which is designed to provide a lighter machine for use where a large device is not necessary, is fixed and the sheet must be moved relatively thereto, the device providing clamping means for the sheet of fabric.
My invention may be understood by referring to the accompanying drawings, in which:
Fig. 1 shows a top plan view of a preferred form of my invention;
Fig. 2 shows a side view, partly in section and partly invelevation, of the machine;
Fig. 3 is a transverse sectional view on line III-III of Fig. l;
Fig. 4 is a view similar to Fig. 1 of a modiiication, with part thereof broken away;
Fig. 5 is a view similar to Fig. 2, ofthe modification shown in Fig. 4.
Referring to Figs. 1 to 3 of the drawings, 5 indicates a bed or table top of suitable construction, through which projects a central shaft or stud 7 having a head 8, a threaded part 9, a reduced portion 10, threaded at 11, and a pointed upper end 12. suitably positioned relatively to the central stud 7 are one or more, preferably two, stud holders 13 having flanged lower ends 13a. In these holders are studs 14, having a reduced portion 15 and pointed upper ends 16.
Renewed December 11, 1924.
The central stud 7 and the holding pins or studs 14 project through the table covering 17 of wall board or other suitable material. The central stud and the holding pins are passed through the fibre sheet A, from which the gaskets are to be cut, when the cutter` is being used, as shown in Fig. 2, and serve to hold the sheet against relative movement.
A plate 20 is removably positioned on the i central stud, said plate having an opening 21 therein through which the stud passes. The plate also has openings 22 therein to receive the projecting upper ends of the pins 14. The plate has a groove ory cam track 23 therein which corresponds to the shape of the gasket to be cut. As shown in the drawings, the cam track is of an oval shape. The plate, when in position, is held against rotation by the pins 14. It may be clamped down against the fabric by a nut 24 screwed onto the threaded portion 9.
Surrounding the reduced portion 10 of the central stud, is a sleeve 25, and screwed onto the threaded part 11 is a hand nut 26.
The cutter moving mechanism comprises a substantially horizontal arm 27 having an elongated slot 28 therein, through which passes the central stud and the sleeve 25, the slot having a width substantially equal to the diameter of said sleeve.
Passing through the arm is a vertical pin 29 preferably having a roller 30 on its lower end which engages in the cam track 23. The
pin 29, which is preferably of the same diameter as portion 10 of the central stud, is slidable vertically with relation to the arm, and is surrounded by a compression spring 31 which urges the arm upwardly.
The outer end of the arm is equipped with a handle 32. The arm has a second longitudinal slot 33 therein, the tops of the sides of the slot being flattened, as indicated at 34.l This slot is for the purpose of receiving adjustable cutters.
The cutters comprise 'cutting disks 35 pivotally mounted in the forked end of a post 3G Which is swivelled in a supporting sleeve 37. This sleeve has a lateral projection at each side at its bottom, designated 37, on which projects one guide portion 37b for slidablyengaging the arm 27. The: top of the post 36 has a nut 36a by means of which the post is heldin place'and which,
if desired, can be tightened against the top of the sleeve 37 to hold the post against rotation. The top of the sleeve is threaded to receive aalock nut 38, which ,nut has a handle 39. This. lock nut may slidablyei'igage the top portions 34 of the'sides orn the slot. By tightening the nut, the sleeve may be locked or clamped against sliding.V A simple adjustment for the cutters is thus proyided. By reason of the swiveled mounting for the cutters, the cutters arezenabled to turn when cutting oval or non-circular gaskets.
In operation, the sheet is properly positioned` on. the tab-le, With the central stud andfpins 14 passed therethrough. Plate 2O is .thenclampe'dinto position by nut 24, and the otherparts are assembled, the roller 30 on. pinA 29 engaging in the cam slot 23 of plate 20. Cutters35 are Aadjusted to cutthe gaskets ofthe desired size `and handle is then moved. By reasonv ofthearm 27 being reciprocable longitudinally relatively to central pin 7, the cutters will be moved Ain ay path; corresponding: to the shape o-cam track' 23', through the action of pin 29. and roller .30; Inl the `device shown, -the lgasket W'ouldbef an oval.v Bysuitably changing the cam` track, different shapesoll gasketsinay be made.
When it is desired to make a circular gasket, with the orm of machine shown in Figs.V 1 and y2, the pin29 'j is removed and the end of central stud k7 is Vpassed'through thei openingin the arm through which pin 29 is ordinarily1 passed.-
of thev cutters .is a circular one.
Figs. 4 and l5 show a modification de signed' forcuttiiig only circular gaskets. Inf

reduced portion 45, a threaded part 46, and
a pivoted end 47.
Screwed on the intermediate threaded part 44 is av clamping nutV 43. Surrounding the shaftand resting on the4 clamping nutf-is a spring 49. 4 Y
Tl'iearm Ois journalled atl about the portion 45 of stud 42., The arm is longitu' dinallyslotted,.as indicated at 52 to receive the adjustable cutterV supporting. means 53, which may be similar to those hereinbefore described. The spring 49 yieldably vsupports the. arin` and .hand Wheel or nut 54 tlireaded onto part 46 serves `tofhold the armidoWn against the actionolthe spring.-
The device is operated in the saine way as the device shoivn in connection With Figs. l and 2, but may be used to cut circular gaskets only.
