2 Claims.

1 My invention relatesto improvements in end guides for rug rolling machines.

The object of my invention is to provide a device that will guide the ends of rugs tokeep the rugs from creeping while being rolled between rollers.

Another object of my invention is to provide a device of the character described that will center itself so as to be in direct alignment with the rug while it is being rolled.

Still another object of my invention is to provide a device that may be retrieved from contact or brought into engagement with the ends of the rug simultaneously and evenly at both sides.

Another object of my invention is to provide a device that is constructed in a manner to eliminate interference during the application of a wrapper on the outside of the rolled rug.

A still further object of my invention is to provide a device that is adaptable for use as an accessory to an existing rug rolling machine.

It is manifest to anyone familiar with the art of rolling rugs on a machine such as covered by my Patent No. 2,215,174 and by my improvements covered by my pending application, Ser. No. 777,754, filed October 3, 1947, now Patent No. 2,573,188, dated October 30, 1951, that it is advantageous to guide the end of the rug being rolled so as to prevent it from creeping-in the rolling operation. It is imperativehowever, to provide a device that will not interfere with the rollers and as the diameter of the rolledportion of the rug increases it is necessary to raise, the end guides in proper proportion to the diameter of the rolled rug, and keep it in alignment with the center of the rug being rolled. Then too, the arrangement must be such as to prevent interference with the paper employed as an outer wrapper to cover the peripheral surface of the rolled rug.

The device specified, illustrated and claimed herein provides all these requisites in an efiicient manner at a nominal cost of construction, and in a way to permit ready adaption to any existing equipment.

Other and further objects of my invention will become more apparent as the description proceeds and when taken in conjunction with the drawings in which:

Figure l is a fragmentary cross-sectional view of one end of the rug rolling machine showing the device in an engaged position and contacting the end of the rug as it is being rolled.

Figure 2 is a similar view with the device engaging the one end of a rug that is rolled completely, and is encased in a paper sheet extend ing outward from the edge of the rug.

Figure 3 is a fragmentary cross-sectional view of the device asshown in Figures 1 and 2 and.

outwardly extending flanges mounted on a shaft H, which is journaled in bearings i2,and which bearings are slidably guided in a vertically disposedslot I3 within the frame member [4 mounted onto a base forming a part of the assembled machine. The roller I0 is brought downward towards the rollers l5 and I5 by gravity and is arranged to be raised by the rug shown as It, as it is being rolled to a cylindrical shape by means of contact with the flanges on the rollers l9, l5 and I5. There is also shown a piston and cylinder arrangement I! which is employed to raise the roller l0 above the rolled rug l6 when the rug is completely rolled and is to be ejected from the machine. 7 i

The bracket l8 attached to the side of the frame M has a pair of vertically disposed apertures [9 arranged for slidably supporting a pair of vertical rods 20 which are equipped with bearings 2| at their upper ends. A slidable shaft 7 member 22 is shown engaging the bearings 2i and extending horizontally in alignment with the rollers ill, l5 and I5. The inner end of the shaft 22 is equipped with a disc 23 having a convex face, and rotatably attached to the shaft 22 by means of the hub member 24. The shaft 22 is also equipped with a pulley member shown as 25 which is slidably attached to the shaft 22 at a point between the bearings 2| and the outwardly depending end of the shaft 22 is provided with a pin 26 which extends outward therefrom and engages an elongated slot 27 in a link member shown as 28, which is hingedly supported and pivoted at 29 to an outwardly extending member 30 forming an integral portion of the bracket l8. The lower end of the link member 28 is pivotally attached to a piston rod 3| forming a part of a piston and cylinder assembly shown as 32 which may be hydraulically or pneumatically operated and which is supportedon the base shown as 33 which also forms an integral portion of the bracket 3.

There is an outwardly extending member 34 shown attached to the frame M at its extreme upper end. This member is provided with an attaching means 35 to support one end of a cable 36 disposed on the outer peripheral surface of the pulley 25 and which has its other end rotatably attached at 37 to the inwardly extending end of the shaft H which supports the top roll Hi.

In operation the device functions as follows:

The rug [6 is fed between the three rollers I 0, I5 and I 5' and is caused to assume a radial contour to form the base of the rolled rug l6,

and as the diameter of the rolled rug increases it will cause the top roller Hi to rise upward by the sliding action of the bearings I2 within the vertical slot l3 in the frame 14.

When the rug I6 is inserted and the rolling operation is started, the piston and cylinder mechanism 32 is brought into operation, and as vacuum is applied to the cylinder in the pneumatic operation, it will causethe piston tobe retrieved, thereby actuating the linlrZBv and forcing the shaft 22inward so that the disc 23 contacts the edge of the rug I 6, and as the diam eter of the rolled rug increases the top roll I0 will be raised, thereby causing the cable attached to the end of the shaft H to draw the pulley 25 upward and raise the shaft 22 in proper ratio, to maintain alignment of the shaft 22 with the center or core of the rolled rug l6. It is manifest, of course, that this arrangement applies to both ends of the rug and is attached to both ends of the machine. It can be operated simultaneously with one source of pneumatic or hydraulic power.

Obviously, the paper wrapping shown as 38 is wider and extends outward from the end of the rug [6, and the discs 23 are of a diameter somewhat smaller than the diameter of the finished rolled rug so that the discs 23 d8 not interfere with the application of the paper 38. After the operation of the rolling and wrapping is completed the pistons are again brought into operation and force the piston rods 3! outward from the cylinders and will bring the link levers 28 into position as shown in phantom in Figure 2, thereby causing the discs 23 to be brought out of the Wrapper and permitting the rug to be removed fromthe machine by the .action of the piston and cylinder arrangement I? working on the lever 39.

In the chosen embodiment of my invention there are features not heretofore described in the prior art, and although I have shown a specific arrangement of the component parts constituting my device, I am fully cognizant of the fact that many change in the form and configuration of these component parts may be made without effecting their operativeness, the spirit of my invention or the scope of the appended claims.

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

1. A device of the character described to be used in combination with a rug rolling machine having a pair of horizontal bottom rollers and a top adjustably and rotatably mounted roller,

the form of a cable, attached at one of wits ends.

to said base, said cableextending around said horizontal shaft and attached at its other end to said vertical adjustable top roller.

2. A device of the character described to be used with a rug rolling machine having two rotatably mounted bottom rollers and a vertically adjusted top roller, rotatably mounted on a base, a frame supported by said base, said device comprising vertically adjustable bearings mounted on said base, a pair of horizontal shafts slidably mounted within said bearings in direct alignment with the point of contact of said top roller with said bottom rollers, means for moving said shafts horizontally, each of said shafts being equipped with a vertical disc on its inwardly disposed end, said horizontal shafts being equipped with rotatable pulleys, and cable means attached at one end to said frame and the other end to said top roller, said cable being disposed over the pulley on said horizontal shaft, thereby causing said horizontal shaft to be raised and loggered with the raisingand lowering of said top ro er.
