CLOTH-LAYING MACHINE.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed June 3, 1912. Serial No. 701,378.

To all whom it may concern:

Be it known that I, J osnrl-i EDWARD J UFE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Cloth-Laying Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved cloth layingmachine arranged to lay the cloth in any desired number of superimposed layers on a cutting table, and to hold the same thereon.

For the purpose mentioned use is made of a table provided with longitudinal runways having retaining means at the front and rear ends for holding transverse rods, around which the cloth is passed, the rear rods being adapted to travel over the runways from the front ends thereof to the rear ends thereof to lay the cloth, and means for moving the rear rods over the said runways from the front ends thereof to the rear ends.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the cloth laying machine; Fig. 2 is a plan View of the same; Fig. 3 is an enlarged side elevation of the head end of the machine; Fig. 4 is a transverse section of the same on the line 44 of Fig. 3; Fig. 5 is an enlarged side elevation of the rear end of the table and showing more particularly the means for holding the beginning end of the cloth in place on the table; Fig. 6 isaplan view of one of the long rods for carrying the cloth rearwardly; Fig. 7 is a similar View of one of the short rods for holding the cloth in position at the head of the table; and Fig. 8 is a side elevation of the front end of one of the runways and the means employed for raising and lowering the same on the table, the latter and the eccentric shaft being shown in section.

On a suitably constructed frame A is held a table B over which the cloth 0 is to be laid in superimposed layers, the beginning end C of the cloth being doubled up and clamped in position in transverse recesses B formed near the rear end of the table B, as plainly indicated in Figs. 2 and 5. In order to hold the end 0 of the cloth in the recesses 13 use is made of a transverse clampin bar I) held in clamping position by 1100(5 E secured on a transverse shaft E provided with a handle E and journaled in suitable bearings E attached to the under side of the table B. By the operator pressing the handle E downward the hooks E are swung rearwardly out of engagement with the clamping rod 1) to unclamp the end C after all the cloth has been laid in superimposed layers, as hereinafter more fully explained.

The table 13 is provided near the sides thereof with longitudinally-extending slots B (see Fig. 4) in which extend longitudinal runways F projecting a distance above the table 13 and terminating at their forward ends in upwardly-extending arms F provided at their outer edges with notches F for the reception of transverse retaining rods G around which pass the front ends of the layers of cloth, as indicated in Fig. 3. The rear ends of the runways F are provided with notches F (see Fig. 1), adapted to be engaged by long transverse rods G employed for carrying the cloth rearwardly and for holding the rear ends of the layers in position at the time, the said long rods G being seated in the notches F The rods G are made sufliciently long to project beyond the sides of the table B for engagement by levers II fulcrumed at H on carriages I provided with wheels I. mounted to travel roarwardly and forwardly on rails J attached to the sides of the frame A. Each lever II is pressed on by a spring H to hold the lever in an inclined position, as shown in dotted lines in Fig. 1. during the return movement of the carriages from the rear end to the head end of the table. The levers H are provided with angular arms I-I adapted to be engaged by catches K fulcrumed at K on the carriages I and pressed on by springs K to hold the catches in engagement with the arms II with a View to lock the lovers H in upright position against the tension of their springs H (see Figs. 1 and 3). The catches K are adapted to engage transverse tripping pins L held on the rear end of the frame A so that when the carriages I move into rcarmost positions the catches K engage the said pins L and swing the same out of engagement with the arms H to allow the springs H to swing the levers H into inclined position as shown in dotted lines in Fig. 1. When the carriages I near the end of their forward travel the levers H engage friction rollers N journaled on plates N adjustably secured by screws I N to the table B at the head end thereof, it

being understood that when the levers H move in engagement with the rollers N they are swung upward into vertical position and are re-engaged by the catches K to lock the levers H in vertical osition. The screws N pass through elongated slots N in the plates N to permit of adjusting the plates lengthwise of the tabe B to insure proper upward swinging movement of the levers H by coming in contact with the rollers N.

In order to impart a rearward and forward traveling movement to the carriage I, use is made of endless sprocket chains 0 arranged on the sides of the frame A and passing over sprocket wheels 0, 0 secured on shafts O 0 journaled in suitable bearings arranged on the main frame A. The forward shaft 0 is connected by pulleys and belt with a countershaft P driven by a suitable motor Q to impart a continuous rotary motion to the shaft 0 and a con tinuous traveling motion to the chains 0 in the direction of the arrows indicated in Fig. 1. On the chains O are journaled friction rollers 0 (see Figs. 1, 8 and i) adapted to alternately engage lugs I I attached to or forming part of the carriage I, it being understood that said lugs I and I are so arranged that when the friction rollers O are on the upper run of the chains 0 then they engage the lugs I to move the carriages I from the head end of the machine to the rear end thereof, and when the friction rollers 0 travel with their chains 0 around the wheels 0 then they move out of engagement with-the lugs I and into engagement with the lugs I to move the carriages I backward from the rear end of the machine to the head thereof.

The cloth C unwinds from a roll R journaled in a frame S which also supports the countershaft P and the motor Q and is arranged on the head of the frame A. The cloth after unwinding from the roll It passes between two feed rollers T and T, of which the shaft T of the rollers T is driven by pulleys and belt from the countershaft P, and the roll It is driven by pulleys and belt from the shaft T When it is desired to use the table without the runways F and the rods G, G, then the said runways F can be lowered in the slots B until the top edges of the runways are below the upper surface of the table B. For the purpose mentioned the runways F are engaged near their front and rear ends by eccentrics U mounted on shafts U journaled in suitable bearings arranged on the under side of the table B, and the said shafts U are adapted to be turned by the use of a wrench or other tool so as to either raise the runways F when using the machine for laying the cloth, or for lowering the said runways below the top surface of the table B whenever the laying device is not to be used.

The operation is as follows: Then the runways F are in raised position and the end C of the cloth is attached to the rear end of the table by the clamping rod D and the cloth is drawn forward over the table then a short rod G is placed on top of the cloth and is engaged with the bottom notches F so as to hold the first layer of cloth in position on top of the table B. The operator now takes a long rod G and passes the same under the cloth a short distance ahead of the short rod G in position in the lower notches, and then the operatorlifts this rod over the ends F and rests the arms of the rod G on the top of the runways F, with the ends of the rod projecting into the path of the levers H. The motor Q is now started so that the carriages I travel from the head end of the machine toward the rear end thereof, and in doing so the levers H engage the ends of the rod G and move the same along over the runways F thus carrying the cloth C along, as indicated in Fig. 1. When the carriages I reach a rearmost position the rod G is engaged with the lowermost set of notches F and at the same time the levers H are released by the catches K engaging the tripping pins L as previously explained, and the carriages I now return to position on the head end of the machine. In the meantime, the operator has placed another short rod G onto the top of the third layer and engages this rod G with the next notches F and then the operator passes a long rod G under the cloth C and shifts the rod over the arms F and engages this rod G with the runways F. As the levers H return they readily pass under the end of the rod G in position at the front ends of the runways F, but then the levers immediately engage the rollers N and are swung into vertical position and locked therein by the catches K, after which the carriages I start on their next movement from the head of the machine to the desired until the desired number of layers are superimposed one upon the other.

' The machine is simple and durable in con struction and is composed of comparatively few parts, not liable easily to get out of orc er.
