RUG-CUTTING MACHINE.

Specification of Letters Patent.

, Patented J an. 11, 1916.

Application filed June 22, 1915. Serial No. 35,635.

, fabrics, or other material.

The invention is particularly adapted for cutting oil cloth, linoleum, or rugs printed on machines which feed the fabric, or bordered material, intermittently, the impres sion being made while the material is at rest. Consequently, in this type of machine a certain'length of material is'prin'ted and the designs are of this length or a multiple thereof.

One object of the present invention is to design a cutting machine so that it will automatically feed the material and will cut it into proper lengths.

A further object of the invention is to provide means for'cont-rolling the feed mechanism and the cutters.

A still further object of the invention is to provide means for adjusting the mechanism to allow for shrinkage or expansion of the goods.

In the accompanying drawings: Figure 1 is a side View of my improved rug cutting machine; Fig. 2 is a plan view; Fig. 3 is a.

transverse sectional view on the line oa, Fig. 1; Fig. 4 is a sectional View on the line bb, Fig. 1; showing the feed clutch; Fig. 5 is a sectional viewon the line co, Fig. 4; Fig. 6 is a sectional plan view on the line cZ-cZ,,Fig. 5; and Fig. 7 is a diagrammatic sectional vlew through the longitudinal center of the machine.

Referring to the drawings, 1 is the frame of the machine, which has an extension 2 on which is mounted the bearing 3 for the spindle of the spool 4 on which is the roll of fabric to be cut. The fabric, in the present instance, has a felted base and a printed surface and is the type'of oilcloth, or linoleum, which is now commonly used.

5 and 6 are two feed rolls mounted on shafts 7 and 8 respectively, adapted to bearings in the frame 1.

9 is a presser roller located ab'ove'the feed roll; 5, and 10 is a presser roll located above the feed roll 6. On ashaftll located above the presser roll 9are eccentrics 12 and these eccentrics are located in the box 13 carrying the spindles of the rolls 9 so that on turning the shaft by the hand wheel 14 the boxes13 will be raised and will lift the rolls clear of the feed rolls 5, allowing the operator to place'the ends of the goods between the two tively, around which passes a drive chain 17 by which the shaft 8 is driven from the On the shafts 7 and 8 of the feed 4 shaft 7, which is driven from the driving shaft 18'through a pinion 19 on the said shaft 18 which meshes with an intermediate gear 20 on a stud 21 and this intermediate gear meshes with a gear wheel 22 looseon a shaft 23 on which is a pinion 24 meshing with an intermediate gear 25 which, in turn, meshes with a gear wheel 26 on a sleeve 27 mounted on the shaft 7. A clutch 28 is arranged on the shaft 23 so as to throw thev gear wheel 22 into and out of engagement with the said shaft.

On the driving shaft 18 are theusual fast and loose pulleys, as shown in Fig. 2. The clutch is preferably made as in Figs. 4, 5, and 6, and has an annular groove therein and also has a longitudinally arranged bolt 28 which is forced toward the gear wheel 22 by a spring 28". The bolt is adapted to enter a notch or recess 22? in the face of the gear wheel and is withdrawn by a lever 29 having a beveled end, as shown in Fig. 4. This lever'rests in the annular groove in the clutch and is arranged to enter a notch in the bolt 28 so that when the clutch is turned and-the'lever is in the groove the bolt will be withdrawn as it comes in contact with the lever, stopping the rotation of the shaft 23 and the feed mechanism controlled byjthe shaft. The lever 29 is pivoted at 30 and is connected by a link 32 having an arm 31 mounted on a shaft 31 on which'is a hand lever 83 sothat on moving the hand lever and shifting the lever 29 it canbe' moved toward and from the clutch. Consequently the feed of the mathe present machine designed to work in'v connection with a prlntmg machine. in

terial is under the control of the operator which the blocks are eighteen inches in Width. Consequently, the mechanism must be arranged so that the material will be fed to the cutters either eighteen inches, or a multiple of eighteen inches, in order to bring the cuts at the proper parting lines.

34 is a reciprocating cutter, shown clearly in Fig. 3, and has a blade 35, which is vertically adjustable and is arranged at an angle so as to make a shear out against the fixed blade 36 mounted on the fixed beam 37 forming part of the frame 1. The reciprocating cutter has vertical members 38 adapted to guides 39 on the frame of the machine and is actuated by cams 40 on each end of a shaft 41, the cams bearing against shoes 38 on the vertical members 38 of the cutter. On the shaft 41 is a clutch 42, which is arranged to engage a gear wheel 43 loose on the shaft 41. The clutch 42 is similar in construction to the clutch 28 and, therefore, need not be described in detail. The gear wheel 43 is driven from the main shaft 18 through an intermediate gear 44 and the clutch is controlled by a clutch hand lever 45, which is connected by a link 46 to one arm of a shifting lever 47 so that when the hand clutch lever 45 is moved it will throw the clutch in and this clutch will turn the shaft one revolution, causing the cutters to make a shear cut and to sever the material. The clutch is so designed that it will be automatically disconnected when the blade 35 is in its raised position, and the blade will remain in this position until the hand clutch lever 45 is again operated. Consequently, while the elements work automatically, they are, nevertheless, under the control of the operator, as in some instances, the designs will vary, some being eighteen inches wide and others multiples of eighteen inches, so that the operator standing at one side of the machine and knowing the clesign, can actuate the lever 32, which operr ates the feed mechanism in order that the cut will beat the proper position on any particular design. If, for instance, a rug fifty-four inches has been printed on the fabric, then it will take three operations of the hand lever, which operates the feed mechanism, to feed the rug from the out at one end of the rug to the opposite end of the rug where the cut is to be made, and, when it reaches this point, the operator shifts the cutter lever and the cut is made. If the next-design is only eighteen inches, then" one shift of the lever will bring the line on which the cut is made in proper position for the cutter to sever the goods at this point.

The cutter is preferably counter balanced and this is accomplished by the levers 48 pivoted at 49 to the frame of the machine and connected by. a link 50 to the vertical 5 members'38' ofcutting frame. le

vers 48 are duplicated at each side of the machine and are connected by a bar 51 on which are the weights 52.

c In some instances, it is desirable, to slit the material into longitudinal lengths before severing it. For instance, a strip of material may be of a width so that a series of three foot rugs and a three foot runner can be printed side by side and as it is de sired to cut the rugs apart and to allow the runner to continue until its end, as the run ner may be of a length equal to four or five rugs, I provide a slitter for separating the runner from the line of rugs and direct the runner strip under the lower beam of the cutter so that only the rugs will pass through the cutting mechanism. This slitter is c0nstructed, as follows: 53 is the lower cutter shaft which is mounted in fixed bearings in the machine and on which are the lower cutting disks 54. 55 is the upper cutter shaft on which are the cutting disks 56. The shaft 55 is mounted in vertically adjustable bearings 57 arranged to slide on standards 58 projecting from the frame of the machine and is actuated by vertically arranged feed screws 59 which pass through nuts on the bearings 57. feed screws are bevel gears 60, which mesh with the bevel gears 61, and the transverse shaft 62, which can be turned by a hand wheel 63 so that on turning this hand wheel the cutters 56 can be adjusted toward and from the cutters 54. The cutter shaft 55 has a pulley 64 around which a belt is passed from the power shaft. 65, 66 and 67 are guide rolls for the fabric. The guide rolls 66 and 67 are located below the lower cutter and the material, which it is not desired to sever by the cutter, is passed around under these guide rolls and under the cutter instead of between the blades.

It will be seen from the above description, that am enabled to cut the printed fabrics in given lengths, or in multiples thereof, as the feeding mechanism will feed automatically a given length and then by repeating the operation the length can be multiplied any number of times before .the cutters are actuated to sever the material and that the material can be slit so as to allow certain portions thereof to pass through the transverse cutters, while other portions of the 1 material will pass under the cutters.

I claim:

1. The combination in a cutting machine for fabrics, of a frame; feed rolls mounted on the frame; means for intermittently operating the feed rolls; a hand lever and clutch for controlling the operation of the feed rolls; a cutter for cutting the fabric; a clutch mechanism and a hand lever for con-'1 trolling the cutter, whereby the fabric is On the upper ends of these the beam 37 of r fed ag vesistance toward-the eaters-ate 5 driving said feed rolls in unison; presser rolls; a driving shaft; a clutch located between the driving shaft and the feed rolls; hand operated means for releasing the clutch to allow it to throw in gear so as to 10 turn the feed rolls, means for automatically withdrawing the clutch at a predetermined point; a transversely arranged cutter; a cam shaft; cams thereon for operating the cutter; a clutch; and a hand lever for releasing the clutch; and automatic means for withdrawing the clutch so that the cutter will make one stroke and will automatically stop.
