CLOTH-MEASURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,567, dated January 17, 1882.

Application filed O.-tober 13, 1881.

To all whom it may concern Be it known that I, ALBERT WINTER, of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Cloth-Measuring Machines, of which the following is a specification.

My improvements relate to machines of the class in which revolving drums are used for measuring cloth as unwound from rolls, and have for their object to insure accuracy, for which purpose I employ devices for clamping the cloth to the drum, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

In the drawings, Figure l is a plan view, partlysectional,oftheimprovedmachine. Fig. 2 is an end view, with the frame of the machine removed. Figs. 3 and 4 are detail sections in larger size, showing the clamping devices; and Fig. 5 is a cross-section ofthe mandrel for holding the roll of cloth. I

A is a hollow drum or cylinder on a shaft, a, sustained by end frames, B B. At one side of the drum the frames B are fitted with mandrels b b, that receive between them the roll of cloth, and at the other side of the drum is aroller, c, for receiving the cloth, which roller is preferably collapsible l'or conveniencein removing the cloth. The drum is provided with clamping devices that are pressed upon the cloth at the feeding side and released therefrom when they reach the opposite side or point at which the cloth leaves the drum, as next described.

(I d are bars extendinglengthwise ofthe drum and through its heads in elongated slots adja-' cent to shaft a, as shown most-clearly in Fig. 3, the ends of the bars being bent or cranked, and terminating near the periphery of the drum.

6 e are rods connected to bars at by slotted heads (1, and extending radially through guides or boxesf, that are fitted between platesf in the surface of the drum, so that the boxes can be adjusted to suit the width of cloth. 0n the outer ends of rods 0 clamps g are pivoted to collars h, that are secured to the rods, and the collars arealso fitted with friction-rollers ion the sides toward the ends of the drum.

lclr are segment-plates fixed on the cross-bars (N0 model.)

of the frames B, such plates extending from the feed side in aline horizontally with the axis of the drum to a point beneath the drum at the delivery side. The plates k are positioned for contact with the friction-rollers on the collars h, so as to give a quarter-turn to the rods 0, and thereby turn the clamps outward and outside the edges of the cloth. The rods e are swiveled in their heads d to allow this turning movement, and the return movem cut is accom plished by a spiral spring, I, on the rods, between the heads d and boxes f, which springs act by torsion to turn the rods 6, and also by expansion to move rods 6 and bars d inward to their normal position. On the rods 6 are pins m, which take outside the boxes f, for retaining the rods projected. The boxes are grooved at f, as clearly shown in Fig. 3, to receive the pins m, so that the springs l may act to move theclamps inward as soon as the rollers 2' clear the plates k and the rods and clamps turn.

The cranked ends of bars dare provided with friction-rollers n, and upon the end frames, B, on the delivery side there are cam-pieces o fixed for contact with rollers a, and shaped to force the bars (I, and consequently the rods 0 and clamps, outward. This occurs in the rotation of the drum, just before the rollers i on the rods 6 reach the plates k, and the cams 0 retain the rods eoutward untiltheclampshavebeenturned outward by the said plates, after which the pins m come into position for entering the grooves of the bearings, at the same time that the rollers on the ends of the bars (1 are released from the cams 0, when the rods 6 are drawn inward and the clamp 9 turned to clamp the cloth.

In operation the cloth from the roll takes upon the drum at or near the horizontal plane of the axis, the clamps g at the feed side being at that time turned upward. By the continued movement of the drum the rollers z clear the ends of plates k, and the springs l, acting first by torsion and then by expansion, turn the clamps inward and draw them down upon the edges of the cloth. The cloth is thus held and is carried by the drum, without risk ofslippiug or displacement, until the clamps reach the opposite side, when the cams 0, by acting on the bent ends of bars d, move the clamps outward,

and the plates 70 turn them downward, and the cloth is free to pass to the winding-roll. At

the moment, orjust before, the cloth is thus released the opposite clamps 9, having reached the feed side, are released and clamp the cloth. The cloth is thus continuously clamped and delivered in lengths of about half the circumference of the drum. A suitable counter will be connected to the drum for registering the revolutions, and the circumference of the drum being known the length of cloth in the roll can be accurately determined.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a cloth-measuring machine, the combination, with a drum, of radially-sliding clamps, and means, substantially as shown and described, for operating the said clamps, as set forth.

ALBERT WINTER.
