terial on a continuous sheet. These short sections of perfect material are rolled on a remnant roll, sometimes three or four pieces being placed on the same roll, depending upon the length of the individual pieces.

While inspecting sheet material in the past, it

has been found necessary to cut out the short pieces, roll them individually, and stand them aside. When a sufiicient number of short pieces were on hand, they were unrolled, reinspected and then rolled on remnant rolls. of pieces per roll varied, depending upon the size of the pieces. This was an extra operation in the inspection of sheet material.

In order to overcome the disadvantages out- 7 Claims. (01. 242-58) The number lined above in the inspection, rolling, and packaging of sheet material, the device illustrated and described herein was developed. I

An object of this invention is to provide an elevator for storing a remnant roll, the top of said elevator forming a portion of the inspection table surface during the normal use of the inspection table.

Another object of this invention is to' provide a storage space forremnant rolls inwhich the roll is convenient for use when necessary but does not interfere with the workman.

A still further object of this invention is'to provide an arrangement whereby short remnant pieces of sheet material are inspected when encountered, rolled, wrapped, and labelled, thereby eliminating the necessity for performing the subsequent operation of inspecting, wrapping, and labelling. I a

In order that my invention may be more readily understood, it will be described in connection'with the attached drawing in which:

Figure 1 is a diagrammatic view of the roll-up end of a sheet material inspection table with the remnant storage elevator in its down or inoperative position;

Figure 2 is a diagrammatic view similar to Fig ure 1 except that the elevator is in a partially raised position so that theremnant roll is accessible for, adding an additionalpiece jofniaterial thereto Figure 3 is a diagrammatic view similar to the other views showing the elevator in its partially raised position, and the roll-up stand is in its raised position; and 1 Figure 4 is a diagrammatic view showing the elevator in its fully raised position with the rollup stand also in its raised position.

Referring to Figure '1 there is shown an inspection table 2 over which the sheet material 3, such as floor or wall covering of the linoleum type, passes while it is being visually inspected for defects. The numeral 4 designates a roll of linoleum on a roll-up device 5 on which the material is rolled after it has been inspected. The bearing for supporting the spindle 6 of the roll is shown The roll-up stand 5 is on a hydraulic lift I so that the finished roll of sheet material can be lifted from the roll-up bearings 6' and removed from the roll-up device. This is accomplished by the platform 8 on the top of the hydraulic lift engaging the roll of sheet material and lifting it from the bearings. Figures 1- and 2 show the roll 4 in its position with respect to the platform 8 when the roll is supported in the bearings.

When the spindle 6 passes through the center of the roll 4 supported in the bearings of the rollup device, the roll is lower than the portion of the table between the roll-up device and the wrapping device 9. In order that the finished roll may be easily rolled by hand from the roll-up device 5 to the wrapping station 9, the section of the table Iii disposed immediately adjacent the roll-up device 5 is attached to the roll-up stand by means of a hinge-joint 8 so that, as the rollup device is raised and lowered, the end of the table It is raised and lowered, pivoting about a hinge-joint H on the other end of the table I0.

' Disposed between the roll-up device '5 and the wrapping device 9 is an elevator, l2, the top l3o'f which forms a portion of the table surface between the roll-up device 5 and the wrapping device 9 when the elevator is in its lowered position. Below the top surface l3 of the elevator l2 there is provided a shelf I4. The top l3, shelf I4, and guide surface I5 of the elevator define a chamber suitable for storing an auxiliary or remnant roll it of the sheet material on which the short remnant pieces are rolled. The elevator I2 may be hydraulically operated. However, it will be understood that any other means may be used for operating the elevator.

In order that the roll of sheet material It may be conveniently transferred from the elevator I2 110 the roll-up device 5, it is;- necessary that the elevator be capable of risingrashfgh as the roll- 3 up device 5 when the same is in its upper position. This is necessary because, if the sheet material in the roll [6 is linoleum or the like, it is too heavy to roll up the inclined surface N by manual force. To overcome this difiiculty the table portion I is mounted in slide bearings at the side adjacent the elevator. Attached to the bottom of the table by means of hinge-joints is a pair of rods or pins I! which pass through the bearings 18 secured to the table support 19. Attached to the bottom shelf [4 of the elevator I2 is a pair of hooks 20 which engage the underneath portion of the table [0 and raise it with the elevator until the table portion in is level. When this condition exists, the roll I6 is easily rolled by hand from the elevator l2 to the roll-up device 5. Figure 3 shows the roll-up device in its upper position and the elevator l2 raised to the point that the hooks 25 engage the under portion of the table II]. Figure 4 shows the elevator l2 in its uppermost position with the portion level between the elevator and the roll-up device 5.

The interior of the remnant roll housing of the elevator I2 is lined with a sheet material lining 2| which is rounded to prevent the roll from be ing damaged by striking the sides of the housing.

In the operation of this device, when a short piece of perfect material is encountered between defects in a continuous piece of sheet material, the 'short piece is rolled on a remnant roll. To accomplish this operation using the present invention, the roll-up; device 5 is elevated to its top position for removal of the completed roll of material. In order to have access to the remnant roll, the elevator 12 is raised to the position shown in Figure *4. The raising of the elevator l2 also raises the end of the table [0 which is engaged by hooks 20 which raise the pins I! in the slide bearings 18. The remnant roll is rolled from the housing formed in the elevator over the table ID to the roll-up device 5. The roll-up device is lowered so that the spindle in the center of the remnant roll rests in the bearings on the roll-up device 5. After the remnant has been placed on the roll, the roll-up device is again elevated to remove the spindle from the bearings. If it is desired to return the remnant roll to the elevator, the roll is rolled across the portion 10 into the housing and the elevator lowered. When the elevator is lowered, the end of the table II! drops again until it engages th support l9 at which point the dropping of the table stops and the elevator continues its downward movement until the top of the elevator is even with the end of the portion I0. 1

If the remnant placed on the roll is the last remnant to be placed on that particular roll, the elevator is lowered before the roll is removed from the roll-up device 5 and the roll is rolled from the roll-up device 5-onto the wrapping device 9. This arrangement corresponds to that shown in Figure 3, except that the elevator is in-the down position.

It will beclear from this disclosure that I have developed a remnant elevator in which the remnant roll is kept convenient to the roll-up device during the inspection and wrapping operation. However, the remnant roll is fully out of the way of the workman and, therefore, does not interfere in any way with the normal functioning. of. the inspection operation.
