Application filed June 2, 1921.: Serial No. 474,342,

To all whom it may concern: 7

Be it known that I, CHARLES J. MoGnn, a citizen of the United States of America, and resident of Osceola, in the county of Mississippi and State of Arkansas, have invented certain new and useful Improvements in Cloth-Cutting Machines, of which-the following is a specification.

This invention relates to means for cutting textile fabric and is intended for use more particularly in connection with the cutting of bagging or jute into appropriate lengths when they are arranged in superimposed layers.

An object of this invention is to provide novel means for permitting the movement of the webs of jute or fabric in order that they may be drawn over a table, means being also provided for clamping or holding the fabric while the cutting operation is being performed.

A still further object of this invention is to provide a cutter and cutter operating mechanism adapted to be moved transversely of the fabric support while the said material is being clamped to prevent the material from being disarrangcd while the cutting operation is being carried on.

It is furthermore an object of this invention to produce a power machine designed to be operated by the drive shaft of any power plant, as an independent unit.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a View in elevation of one end of the machine showing the manner of operating the cutter; V

Figure 2 illustrates a side elevation of the device with the cutter operating mechanism omitted;

Figure 3 illustrates a plan view of the cutter;

Figure 4 illustrates an enlarged detail view of a tensioning device;

Figure 5 illustrates a plan view of the embracing one embodiment-of the invention,

and the mechanism includes an elongated table 10 havingtransversely arranged guides 11 and 12 under the top thereof which form altrack for the cuttingtframell which cutting frame has anzoperating handle 14: by; which it may be pulled to carry the knife 15 transversely of the table. As shown, the knife 15 is mounted on a shaft 16 having a pulley 17' engaged by a'belt 18 and the said belt travels with the carriage from one side of the table to the other. Any suitable means may be provided for driving the belt by power applied to the shaft 19. Ashaft 20 carries a pulley 21' and a pulley 22 is mounted on the shaft 19. The shaft 20 is applied to an arm 23 hingedly mounted as at 24 to a post 25 so that the said arm mav rise and fall, as shown in the full line and dotted line positions. It is intended that the weight of the pulley 21 and parts associated with it, shall, be sufficient to cause movement of the carriage to return it from the dotted line position shown in Fig; 1 to the full line position shown in Fig. 1, it being understood that after the carriage receives momentum,

it will travel to the said full line position.

The jute, bagging or fabric to be cut may be stored on rolls 26 and j 27 rotatably mounted ona post 28, and of course, a greater number of rolls may be mounted so that the webs or material therefrom may be drawn into interposed positions on the table, in order that a greater number of layers of material may be cut at one operation, but the foregoing illustration will, it is thought, suflice as an understanding tothose skilled in the art. As a means for preventing the displacement of the layers of fabric while the cutting operation is being carried on, a clamp is mounted in operative relation to the table, and in the present embodiment of the clamp, a post 29 is supported in vertical position from the table at one. side, the said post having a bracket 30 with an idler or sheave pulley 31 thereon. A flexible member 32 operates over the idlerand connects to the outer end of the clamp, as shown at 33. The said clamp in the present embodiment in cludes two clamping elements at and 35 held in'spaced relation to each other by the combined yoke and handle 36 at the outer end, the inner ends of the said members 34: v and 35 being oscillatableo-n a shaft 37 with heads suchas 38 pressed down bysprings position shown in Fig. 1.

such as 39 or rods 4L0 applied to a supplemental frame 4:1, The flexible member 32 has a Weight 42 Which app-roximately counter-balances the Weight of the clamp, and it.

is effeotive to hold the clamp intheelevated The clamping members are provided with a latch &3 which engages the lug 4.4 for holding the clamp in operative relation to thetop of the table While the cutting operation is carried on, and the said clamping members are returned to their elevated position by the Weight 42.

20 ual pull on the handle of the cutter carriage,

the said carriage, as stated, being returned automatically to normal position by the Weight of the elements associated With the oscill'atable arm 23. i

I claim: e In a cutter for cloth in superimposed layers, a table, guides transversely arranged in'spaced relation to each other under the table, a carriage mounted for movement on the guides, a shaft rotatably mounted in the carriage, a cutter on the said shaft, a belt operating over the shaft for driving the same, pulleys over which the said belt is operative, a hingedly mounted pulley engag ing the said belt, means fornroving the carriage in one direction and elevating the hingedly mounted pulley,-the saidpulle-y being operative to return the carriage to its normal position. i p

CHARLES J. MOGEE.
