CUTTER.

SPECIFICATION forming part of Letters Patent No. 773,563, dated November 1, 1904.

Application filed December 3, 1903. Serial No. 183,666. (No model.)

To ctZZ whom, it uty concern.-

Be it known that I, GEORGE E. GINN, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Cutter, of which the following is a specification.

The objects of my invention are to provide a machine for cutting carpet into very narrow strips as it is passed between the rollers of my device and, further, to provide cuttingblades which can be easily placed in position relative to the machine or removed from it.

A further object is to provide a device of this class which can be operated by hand or by power and rollers in which are so arranged that they will draw the carpet forwardly between them and against the cutting edges of the knives whose blades extend between the rollers.

A further object is to provide advancingrollers so arranged with a series of grooves in their peripheries that the blade of a knife can be inserted in these grooves and that as the carpet is advanced it'will be drawn against the cutting edges of the series of knives.

A further and material object is to provide a cleaner for each groove in the series of grooves which are capable of horizontal adjustment.

A further object is to provide a series of cutting-blades so arranged that their point of contact with the carpet advanced between the rollers can be changed at the pleasure of the operator.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a rear elevation of the complete machine. Fig. 2 is a cross-sectional view of the machine. Fig. 3 is a detail view of one of the cutting-blades. Fig. 4 shows in detail the number of the cleaning-blades and shows the way in which they are mounted.

Referring to the accompanying drawings, it will be seen that I have provided a frame comprising the end portions 10, the front side portions 11, and the rear side portion 12, connecting the ends 10. At each corner of the frame is a leg 13, designed to support the sides and ends of the frame. Extending upwardly from each end of the frame are two upright posts 14: and 15. Mounted between each of the posts 14 and 15 is a bearing 16, immediately above the frame of the machine. Extending longitudinally of the frame and having each end thereof mounted in the bearing 16 is a roller 17, having a series of grooves 18 in its periphery.

Slidingly mounted above the bearing 16 and between each pair of posts 14: and 15 is the bearing 19, and in these bearings 19 the roller 20 is rotatably mounted, said roller having a series of grooves 21 in its periphery corresponding to the grooves 18 in the periphery of the roller 17, and when the rollers 17 and 20 are in position that is, the roller 20 is above the roller 17the groove 21 and the grooves 18 will be in line with each other, so that a series of grooves is formed between the body of the roller 17 and the body of the roller 20. Mounted above each of the bearings 19 is a piece of rubber 22 or other springing substance, which is normally held in position by means of the screw-threaded shaft 23, which is designed to be operated by the wheel 24, mounted on its upper end. There is a screwthreaded shaft 23 at each end of the frame, and these shafts are so arranged that the upper roller 20 will be maintained in position relative to the lower roller 17 as the rollers are rotated, so that the upper roller can be moved upwardly very slightly and downwardly very slightly to admit a piece of carpet of greater or less thickness between the rollers at the pleasure of the operator.

Mounted on one end of the shaft 20 is a gear-wheel 25. Mounted on the corresponding end of the roller 17 and in mesh with the gear-wheel 25 is a gear-wheel 26, so arranged that as the roller 17 is rotated the roller 20 will be correspondingly rotated. Mounted on the opposite end of the roller 17 from that upon which the gear-wheel 26 is mounted is a large gear-wheel 27, which is outside of the end 10 of the frame which is nearest it. Near the side 12 of the frame and mounted above the frame is a boxing 28, in which the shaft 29 is rotatably mounted, having the gear-wheel 30 mounted on it and in mesh with the large gearwheel 27. Mounted on the outer end of the shaft 29 is the driving-wheel 31, which is designed to be driven in the ordinary way to drive the operative parts of the device.

Connecting the upper portion of the two posts 15 and extending longitudinally of the frame are the metal plates 32 and 33. Standing in a vertical position and attached to these blades is a series of forked knife-supports 34, there being one of these knife-supports 34 for each of the grooves in the rollers, and there is one of these knife-supports behind each groove in the roller 20. Connecting the lower extremity of the forked portions of the knifesupports 34 is a pivot 35. I have provided a blade 36, having the weighted handle 37 thereon, the blade 36 being attached to one side of the handle 37. In the lower portion of the blade 1 have provided a series of holes 38, designed to admit a staple 39 or other retaining means. There are series of these knife-blades 36, and one of these blades is inserted between the forked portions of each of the knife-supports 34, and it extends forwardly into the grooves 18 and 2-1 immediately in front of these knife-supports. These knives are sup ported by means of the pivots 35, and they are prevented from slipping forwardly by the staples 39, which rest against the forked portions of the knife-supports 34. The weighted handle 37, which is attached at the rear of the knife-blade 36, is designed to normally force the forward end of the blade forwardly.

Extending longitudinally of the frame and connecting the upper extremities of the posts 14 is a metal plate 40. Extending downwardly from this metal plate 40 are the supports 41. Attached at the lower end of these supports 41 is a bar 42, against which the forward ends of the knife-blades 36 are designed to rest and be prevented from being forced upwardly beyond a certain point by the weighted handles 37.

Mounted above the frame and extending from the front side of it which is adjacent to the front side 11 and extending to a point slightly between the front sides of the rollers 17 and 9.0 is an inclined platform 43, upon which the carpet is to be placed and moved forwardly to a position where the rollers take hold of it and advance the carpet. Extending from the under portion of the side 11 of the frame to the lower portion of the legs on the opposite side of said frame is a second inclined platform 44, upon which the carpet which has been cut falls, and the narrow strips are carried off to a position at the rear of the machine.

h Iounted in the end portions 10 and extending longitudinally of the frame is an angular metal strip. Attached to and between the side erases portions of said strip is a rod 46, upon which a series of cleaner blades 47 is mounted. There is one of these cleaner-blades 47 for each of the grooves 18 in the rollers 17, and these blades are so arranged that as the carpet is cut into small strips and dirt and other foreign substances are forced to the grooves 18, the cleaner-blades 47 will keep these grooves free from this substance, and thus keep the roller 17 always in condition for use.

In practical operation and assuming that the parts are assembled as above described, the operator places the piece of carpet which is to be cut into narrow strips on the platform 43 and moves it forwardly to a position where the rollers 20 and 17 causes it -to be drawn forwardly. Inasmuch as these rollers are r0- tated in opposite directions as these rollers draw the piece of carpet forwardly the cutting edges of the knife-blade 36 will engage the carpet and ,cause it to be severed into narrow strips, there being a constant drawing force to move the carpet forwardly against the cutting edges of said blades, inasmuch as the rollersare being constantly rotated while the device is in operation by means of the drive-wheel 31 and its connections. On account of the way in which the knives are constructed and the manner in which they are mounted if one knife becomes dull this knife can be easily removed and another one put in to replace it or the entire set of knives may be removed and replaced by other knives without taking the machine apart or doing anything to the machine except to withdraw the knives and put the others in their places. On account of my peculiar arrangement and construction of knives the liability of the knives being dulled is reduced to a minimum, inasmuch as the cutting edges of the knives do not engage anything except the material which is to be cut. In connection with the use of my device it may be said that the drive-wheel 31 may be operated by hand or driven from a power-machine.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is
