IMPRo-vEMENT IN cLoTH-Ml-:Asunmc APPARATUS.

To all whom it may concern Y Be it known that we,BENJAM1NM. HAR- Ron and FREDERICK N. OGDEN, both of the city of New Orleans, in the parish ofOrlean's and State of Louisiana, have invented a-new and useful improvement in machines forv tallying and making into rolls bagging and other fabrics, which improvementis fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a side elevation; Fig. 2, a back view of our machine. Fig. 3 is across-section of the tallying-cylinder, and Figs; 4,- 5, 6,7, and S-aredetailed views of parts of our f -i-nvention. Y

lhe nature of our invention consists in certain constructions and combinations `of parts, hereinafter described and specifically claimed, whereby the following objects are attained-*1A First, the fabric to be measured andpnt up into given sized rolls or bolts can betaken -in large rolls directly from the loom or other place, and placed in our machinewith'the greatest convenience and facility.

` Second, the quantity ofI material placed in each smaller roll can bebme'asured whileA the .fabricis being rolled from thelarge roll in'tothe smaller rolls, and the quantities in each roll can be regulated at the will` of the operator 5 and when the determined quantity is rolled upon thfe roller-shaft, the fact will llbefindicated to'the operatorby a sound.

Third, the edges of fthe'. fabric are Y'caused to pass to the roll in lines at right angles to the axis of the roller-shaft, and thus the ends ofthe smaller rolls are kept perpendicular with the axis of said roller from center to circumference.

Fourth,the small rolls can be taken from the roller-shaft with facility, and said shaft used repeatedly for the same purpose, and while this is the case the shaft is strong and not liable to Vbecome deranged or inoperative.

In the drawings, A represents an open frame of simple construction, the basis of which is extended toward the front to serve as a support for the'feed-rollers B, upon which the fabric C' is received as it comes from the' D D are friction rollers, and E is a measuringcylinder, the circumference of which is equal to a yard, or any other unit of measurement, and the surface of which is lprovided with pricks or pins e, whereby the sliding of the fabric over the said cylinder is prevented, and both the fabric and cylinder are compelled to move at exactly the same rate of speed. The shaft of the cylinder E is provided with a single cog, e', which revolves with the said cylinder, and at each-revolution thereof'engages a tooth, f, of a counting-wheel, F, and pushes it forward. The said wheel F is pivoted to .the frame A, at a, and is prevented from casual movement bythe springpawl G, which is fastened to the" frame A, and by its wedge-shaped headjg takes'in between the teeth f of the said countingwheel. The wheel F is also provided with a cam, H, terminating with a step, h. Upon the said'cam El a spring, 1, fastened to the frame A, is made to bear, so that when it arrives at the. step -h of the cam H it suddenlyslips oif and comes down upon the-face offthewheel F with a snapping sound, thereby indicating the finishing of the intended measurement. Tlleffabric is passed from the `roll G to the rolls D D I), and rol-ler or cylinder E, and therefrom between guides K toLa shaft, J.

The said guides K are plates or boards supported by horizontal sliding screw-bolts L, which are passed through the frame A, and screwed into the guides -K, and which are provided with heads l outside Yof the frame. `A number of tension-sprin gs, 7c,- are fastened between the frame A and the guides K, whereby the heads l are kept close against the frame and the guides are kept at the proper distance from each other. The bolts L, may be screwed a greater or less distance into the guides and thereby made to adjust them to the width of the fabric. The springs k, areof such a tension as to yield to any slight variation in the width of the fabric, but not to a deection from a right course.

The shaft J is composed of two equal halves, which are inversely the counterparts of one another, and both halves have a head, M,

with a socket, m2. The halves are formed with matching-surfaces j j and j j] those portions j j of said surfaces being parallel, and those j j being of a wedge form. The

wedge surfaces are formed outside of the parallel surfaces j j of the respective halves, that of one of the halves of the shaft being inversely the counterpart of the other half thereof, and the highest parts of these Wedgeshaped edges tit against the lowest parts of the said edges, and thus when the two halves are placed upon one another and their free ends inserted into the sockets m2, a solid and longitudinally-braced shaft, which is tongued and grooved together and presents no gaps or projections, is produced.

In the cross-sectional views, Figs. 7 and 8 of the roller shaft J, the manner in which the halves lit in one another is clearly shown, and in Fig. 4 the wedged edges on the respective .halves are plainly indicated. This shaft J has journals m m and cranks m connected rigidly to the heads M M, and by constructing ,it in the peculiar manner specified it is made to possess great strength, as the lighter ends of the respective halves are strengthened by lthe heavier ends thereof; and facilities for withdrawing the said halves from the roll of fabric are alforded as the friction against the wedged edges diminishes very rapidly in the .diccticn in which the halves are pulled apart, and this friction is very slight at all times on account of the narrowness of these edges. When the halves of the shaft are united, the journalsm thereof exactly fit the open journalbearings N ofthe brackets n on the frame A, and thus the said shaft can be easily placed in and removed from its position as eircum .stances require.

Operation: It' a piece of cloth or other fabric is to be measured off it is placed on the feed rollers B. The number of yards or other units of measure represented by the circumference of the cylinder E is counted olf on the cogs f of the Wheel F, beginning ata point back of the step h of the cam H. The cog e on the cylinder E is then moved back until it touches one of the cogs f of the wheel F, and the fabric is passed over the cylinder E up to the shaft J. The fabric is then Wrapped around the sharp corners of the shaft J, which is then turned by means of the cranks m', the guides K in the meantime keeping the fabric straight, and thereby insuring its being wound up straight and evenly on the shaft. As one tooth j' after another is moved ahead by the cog e on the revolving cylinder E, the cam H slides under the free end of the spring I, and gradually lifts it until the spring arrives at the steph, and falls from said step and announces by sound the nishiug of the measurement. The fabric is now cut o' on the cylinder E, at the point where it is desired a new measurement shall begin.

Having thus described our invention, what we claim as our own, and desire to secure by Letters Patent, is-

1. A tallying and rolling machine, cornbining feed-rollers B, tension-rollers D, measuring-rollers E, having a cog, e, a counting- Wheel, F, having a cam, H, spring I., and pawl G, adjustable guides K, and shaft J, all coustructed and operating substantially as hereinbefore set forth.

2. The combination of the measuring-cylinder E, having pins e, the counting-wheel F, having a cam, H, with the step h, the spring I, and the pawl G, operating substantially as and for the purpose set forth.

3. The lateral guides K, the tension-springs k, and the adjustable sliding bolts L, having heads l, all constructed and operating substantially as and for the purpose set forth.

4. The shaft J, upon which the fabric is rolled, consisting of the halves j, having the wedge-shaped edges j', which are outside of parallel matching or tongued and grooved portions of the shaft, and the journaled heads M, having the sockets m2, all constructed and operating substantially as and for the purpose set forth.

Witness our hands in the matter of our application for patent for improvement in machines for measuring and rolling cloth, fabrics, &c.
