CLOTH-MEASURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,672, dated February 15, 1887.

Application llcdMarcli 26. 1886. Serial No. 196,636. (No model.) I

.To @ZZ whom, it may concern:

Be it known that l, N ELs W. HAwKnNsoN, of Litchfield, in the county of Meeker, State of Minnesota, have invented certain Improvements in Cloth-Measuring Machines, of which the following is a specification.

The object of the present invention is to furnish a light, simple, and inexpensive machine for measuring cloth, and the invention consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part-ol' this specification, Figure 1 is a side elevation of my improved machine. Fig. 2 is a plan of the same. Fig. 3 is a transverse vertical section on line m x, Fig. 2. Fig. 4 is an enlarged detail of the registering mechanism; Figs. 5, 6, and 7, details of the chucks.

The machine comprises a supporting-frame, standards supporting the reels for the clot-h, measuring-rolls mounted between the reels, a casing that surrounds and protects these rolls, and a registering mechanism that is operated by the rolls.

In the drawings, 2 represents the supporting frame or base of the machine, upon which the other parts of the machine are supported.

lAt each end of the frame or base is a cross plate or sill, 3, having a slot or way therein, in which two standards, 5 5 and 7 7, are supported, being free to move longitudinally therein. The lower ends of the standards are provided with screw-threaded holes, and rods 9, having right and left screw-threads thereon, are mounted in bearings at the ends ofthe ways and pass through the threaded holes in the standards. The rods 9 are provided with handles 11, and by turning these rods the standards are moved equally toward or from each other.

In the upper end of each standard is mounted a chuck, 13, for holding the cloth reel or board. One of these chucks is provided'with .a handle, 15, and each is of substantially the construction shown, having a central groove, 16, to receive the end of the cloth-board, and four sharp points, 17, that may be forced into the end of a roll when it is desired to wind the cloth upon a roll or unwind it from one. Two of the chucks are also provided with springhooks 19, that are centrally mounted in the `which the rolls are arranged.

cross-groove 16. Vhen a board is placed between the parts of the chuck, the spring-hook is forced outward beyond the surface of the chuck into position to have the cloth hooked thereon. When the board is removed by moving the chucks away from its ends, the spring-hooks are retracted and release the cloth.

Mounted upon the base or frame 2, between the standards, is a two-part casing, 21 23, in Thelower part, 2l, of the casing is open at the top, and is otherwise inclosed by the end walls, 22 22, the bottom 24, and the side walls, 26 26. The upper part, 23, of the casing is secured by hinges 2O (see Fig. 2) to one edge of the lower part. lt is open at the bottom and consists of the end walls, 27 27, the top 28, and the sloping side walls, 30 30. In the side walls are openings, that may be closed by doors 31, that are hinged to the upper edges of the side walls of the lower part ofthe casing. Then the doors are closed, as in Fig. 3, the rolls are entirely inclosed in the casing, and are thereby protected' from dust and injury from other causes.

The upper or central measuring-roll, it will be seen, is mounted in the hinged portion of the casing, and the lower or holding rolls are mounted in the stationary part of the casing. rlhe part 23 of the casing may be turned-up on its hinges 20,carrying the measuring-roll with it above and away from the other rolls. The doors 31 being open, a clear passage is formed through the casing between the upper and lowerrolls,and through this the cloth may be passed from one reel to the other. After the cloth has been passed through the casing the hinged part is turned down again toits former position. The light paper roll is mounted in the hinged part of the casing, and does not add materially to its weight.

It is necessary in cloth-measuring machines in which the measuring-roll is turned by the friction between its surface and the surface of the cloth that the roll be very light, in order that the friction upon its journals may be reduced to the minimum. Heretofore there has been much difficulty in these machines in preventing the cloth from slipping over the roll. The paper roll used by meissolightthatthere is very little friction upon its bearings,and the ICO paper surface does not gloss and wear smooth, but always presents a surface to which the cloth adheres closely. Vith this roll thereis no liability that the cloth will slip and the measurement be inaccurate.

Mounted in bearings in the upper part of the casing is a measuringroll, 33. rlhis roll is preferably just eighteen inches (one-half yard) in circumference, and I prefer to form it of a hollow shell of paper, or similar light material, that is supported by a central shaft, which maybe composed of ordinary gas-pipe, and longitudinal supporting-bars. The roll, as thus constructed, is exceedingly light, and turns easily in its bearings.

Mounted in bearings in the lower part of the casing, upon opposite sides of the roll 33, are the cloth-holding rolls 35 and 37. The axes of these rolls are a little below the axis of the roll 33.

The roll 35 is preferably solid, and it is supported in boxes that rest upon springs 39, that press this roll against the roll 33.

Aregistering mechanism is mounted on the upper part of the casing, and is connected with the roll 33 and actuated thereby. lThe construction and arrangement of this mechanism is as follows: Secured to the end of the upper part of the casing is a small casing, 41, that incloses the parts of the registering mechanism. A gear-wheel, 43, is mounted on the end of the shaft of roll 33. A gear,45,having twice the number of teeth of the gear 43, is mounted on ashortshaft, 47, iu the casing 41. Theshaft 47 projects through the casing 41 and carries a pointer, 4H. The circle traversed by the end of the pointer is marked 0 at the lower point, and with suitable marks to indicate the quarter, half, and three-quarter yard points. A mark, 36, is also placed on the circle to indicate the point at which the pointer should be set to allow for the amount of clot-h at the beginning between the rolls and the standards carrying the board upon which the cloth is wound.

Below the gear 45, outside the plane thereof, are the units and tens wheels 51 and 53. These wheels are mounted upon studs that turn freely in bearings in the walls of the casing, and have upon their outer ends the arms 52 and 54. Numbers from 1 to 0 are marked on each wheel near its edge, the Os being under the arms. These wheels turn freely in either direction, and by taking hold of the arms they may be turned in either direction to set them at any desired points.

rllhe unitswheel 51 has ten ratchet-teeth or notches upon its edge, and the tens-wheel 53 has a similar number on its edge. The wheel 45 has a lug or pin, 55, that is adapted to engage the notches of the units-wheel and to move this wheel one notch for each revolution of the gear 45. The wheel 5l has alug thatis adapted to engage the wheel 53 and to move it one notch at each revolution of the wheel 51.

The gear-wheel 45 will make one revolution while the roll 33 makes two, and will thus indicate the measure of one yard. The pointer 49 will show the fractions of yards, and the units and tens wheels will register the number of yards.

rIhe units and tens wheels may each be turned freely in either direction, and thus may be set by simply turning their arms 52 54 toward each other.

Vhen a rollof cloth is to be measured, it is placed with its board or roll in the chucks on the standards at the left hand in Figs. 1 and 2, and the upper part of the casing is turned up on its hinges, carrying the roll 33 above and away from the other rolls. rllhe doors being open, the cloth is then carried under the roll 33 and over the other rolls. The end of the cloth is attached to the hooks, and the roll 33 is returned to its normal position. The units and tens wheels are set with their arms pointing toward each other, and the pointer 49 is placed over the mark 36. The cloth is then moved through between the rolls and wound upon the board or roll that is held in the chucks in the standards 7 7.

The standards may be moved to adjust them for cloths of different widths.

A special advantage is obtained from using the light paper measuring-roll with the solid bearing-roll, as the cloth is firmly held against the light roll, which carries the cloth with it, and, owing to its lightness, does not slip over the cloth.

I claim as my invention 1. The combination, in a cloth-measuring machine, with the base and reelsupporting standards, of the twopart casing located between said standards and consisting of the stationary part 21 and the movable part 23, hinged to said stationary part, the rolls 35 37,

journaled in said stationary part, and the roll 33,journaled in said movable part between the rolls 33 and 35.

2. In a cloth-measuring machine, and in combination with the base and standards, the two-part easing consisting of the stationary part 21, the movable part 23, hinged thereto, the doors 31, the rolls 35 37journaled in the stationary part 21, the measuring-ro1l33, journaled in the hinged part 23, and registering mechanism connected with said measuringroll, substantially as described.

3. In a cloth-measuring machine, a holdingchuck having a cross-groove adapted to receive the end ofa board, and spring-hooks in said grooves adapted to be pressed outward to engage the cloth when the board is in position, substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of March, 1886.
