ATTACHMENT FOR OVAL OR SQUARE MAT CUTTING MACHINES.
SPECIFICATION forming part of Letters Patent No. 671,208, dated April 2, 1901. Application filed January 81, 1901. Serial No, 45,491. (Nomodehl To all whom it inaoyconcern:
Be itknown that I, J OHN N. CUNNINGHAM, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Oval or Square Mat Cutting Machines, of which the following is a specification, reference being had therein to the accom panying drawings.
This invention relates to certain new and useful improvements in oval cutting machines, and more particularly to that class of machines to form mats for frames or the like.
The invention has for one object to construct a device of the above-described character that will eifectually retain a large number of layers of matting or other suitable material employed for the above-mentioned purpose.
Another object of the present invention is to construct a mechanism that will firmly retain and clamp in an effectual mannera number of layers of cardboard or the like and will permit a cutter to cut through several thicknesses in one operation.
Another object of this invention is to construct a machine of the above-described character wherein the mats may be easily released, and, furthermore, wherein the oval cut from the mat may be readily removed.
With the above and other objects in view the invention consists in the novel combination and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claims.
In describing the invention in detail reference is had to the accompanying drawings, forminga part of this specification,and wherein like numerals of reference indicate corresponding parts throughout the several views, in which-- Figure 1 is a side elevation of myimproved tending arms 5 of the yoke 6, said upwardlyextending arms extending through said open in gs. The said yoke 6 is provided with a downward extension 7, having a bifurcated end 8, to which is pivotally secured a footlever 9, said foot-lever 9 being pivotally connected at its end, as shown at 10, to a lug 11, arranged to the cross-bar 12 of the frame. The said yoke 6 is also provided with an apertured boss 14, through which extends the rod 15, connected at 16 to the under face of the table 4, the lowerend of said rod being attached at 17 to a coil-spring 18, connected at 19 to the foot-lever 9.
The reference-numeral 20 represents a yoke having a round or oval central portion 21, this yoke being pivotally secured at 22 23 to the upper extremity of the upwardly-extending arms 5.
The reference numeral 24: represents a toothed rack which is suitably secured to the connecting-piece 25 of the standards 3, the latter being adapted to engage the foot-lever Qand retain the same in position.
The reference-numeral 26 represents apertured lugs arranged at each side at the rear portion of the table to receive the frame 27 of the cutter, said cutter being provided with a down wardly-extending curved arm 28, said arm being engaged by the end 29 of the lever 30, which is fulcrumed at 31 to the side of the table, the forward end of said lever carrying a handle 32. This lever has an inwardly-projecting portion 33, which is adapted to engage the toothed rack 34 and retain the cuttingframe in an elevated position when desired.
The reference-numeral 35 represents a cutter arranged to the forward end of the cutting-frame, the latter being operated in the usual manner.
The operation of my improved oval-cutting machine is as follows: A number of layers of mate that are to be out are placed upon the table under the yoke 20, foot-pressure applied to the foot-lever, and the same locked in the toothed rack. The lever 30 is thenraised, thereby lowering the cutting-frame and also the cutter. The operation is then performed in the well-known manner, the cutter penetrating through a number of layers in one operation, and the ovals produced by this 0peration can then be readily removed by the use ofa knife or any sharp instrument through the round or oval portion of the yoke.
The many advantages obtained by the use of my improved device Will be readily apparent from the foregoing description, as it has been heretofore a difficulty to obtain a firm grasp upon a number of layers.
It Will be noted that in case square mats are to be cut in lieu of the oval yoke square clamps may be employed that will firmly engage the upper face and sides of the mats and retain the same in the proper position. Further, it Will be noted that various changes may be made in the details of construction without departing from the general spirit of my in vention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In an oval-cutting machine, the combination of a suitable frame and table mounted thereon, upwardly-extending arms extending through said table, a yoke secured to said arms, a foot-lever connected to said arms, a cutterframe, means to raise and lower said cutter-frame, and acutter arranged upon said cutter-frame.
2. In an oval-cutting machine, the combination of a suitable frame carrying a table having openings therein, upwardly-extending arms arranged in said openings, a downwardly-extending portion connecting said arms, a foot-lever secured to the lower extremity of said downwardly-extending por- 35 tion and pivotally connected thereto, said foot lever being pivotally secured to the crossepiece of the frame, a rod secured to the under face of said table, an apertured boss scoured to the yoke, said rod extending through 0 said boss, a spring connecting said rod and foot-lever, a cutter-frame pivotally secured to the rear end of said table, a downwardlyextending arm arranged and carried by said cutter-frame, an operating-lever adapted to 45 raise and lower said cutter-frame and operate against the lower face of said curved arm, a yoke pivotally secured to the upper extremity of said arms, and a cutter rotatahly secured in said cutter-frame and operating in 50 JOHN N. CUNNINGHAM.
