TO ALL WHOM IT MAY CONCERN:

Be it known thatl', WILLIAM RHODES ARNOLD, of Providence, in the county of Providence, and StateV ci' Rhode Island, have invented a new and improved Machine for Measuring and Lapping Tape and Braid; and I do hereby declare Vthat the following is a full, clear, and exact description thereof, which will enable others' skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in'whieh- Ifigure 1 is a-perspective view of my invention. v

Figure 2 is a detached front view of the muin driving-wheel.

Figure 3 is a central cross-section taken on the line a; zu, iig. 2.

Figure 4 is a detached view ofa guide-pin. i v Similar letters of reference indicate like parts.

The object of this invention is to measure tape, braid, bindingor other similar goods, into exact lengths for the trade, sayin piecesiive yards long, and at the same time form them into sticks by lapping or folding.v Upon a solid base, Aure secured two standards B B., upon and between which is hung a plate spur-wheel C, to bcturned by hand with the crank D. The spur-wheel C gears into a pinion, E, above on a lsliding-shaft, a, which has its bearings in thestandards B B. Just within thc periphery of the gear-wheel C, on the side of it, is placed a cam, b, which extends around nearly or quite one-half of the circumference ofthe wheel, as shown in iig. 2. The face of the cam b is in the plane of the side of the plate-wheel C, and projects above the plate-face one-half-incln as shown in iig. 3. One end ofthe cam is bevelled, and the other end has a nose or projection, Z1',` lto form a recess behind it. vOn the inside ofthe standard B, at the lower part, is fastened one end of a spring, e, which extends up and terminates in a fork, c', which clutches or clasps the shaft a between the ring-shoulders i :Zd that confine its uiovement'on the shaft..- A pin, g, having'a hooked outer end, z, is fastened on the spring c, so that the ends of the pin may strike the dat platefacc of the wheel O, and the hook 7i lie in the recess-behind the projection 5 on the cam I). The shaft a may be moved in its bearings lengthwise, so as to press the upper end of the spring c outward, and raise the pin y so that the hooked end h will lie upon the cam when necessary, as hereinafter described. On the end of the sliding-shaft a, outside of the standard B', is aiiixed a pair of lapping-bars, it', which for ordinary use are made about seven inches apart, and :is-the gear-wheel C is made proportioned to the pinion E, so as to give the shaft a fourteen turns in one revolution, a stick of ve yards of braid isformed on'the lapping-bars i z' for each revolution of the gear-wheel C.

When the machine is started, an end of the braid having been caught on ahook, c, on one of the lappingbars z', the shaft a is pushed forward so that the end of the pin g is mounted on the cum I) at the projecting end b. The gear-wheel C is then turned until the pin g slips off lthe cam at the opposite inclined end, when it coutinues to travel around on the face of the plate of the wheel O until the hook L passes into the recess behind the projection b', and thus stops the machine. It will be observed that during this revolution of the gear-wl1eel C, the turning of; the lapping-bars z'z'has folded or lapped around them a. piece of braid or tape of a definite length, fed from a suitable fra-me, as shown in red, and the length of braid thus folded or lapped has been formed in two parts, folds, or laps, by the action of the spring c, which has forced the shaft a backward in its bearings the thickness of the cam lb on which the 'guide-pin g travelled when the pin slipped from the cam. One of the laps or parts of the length of braid thus folded was made over one point or part of the lapping-bars z' i, while the pin g moved on the cam b, andthe other part while it moved the balance of the revolution of the gear-wheel C over its plate-face. The length is then made into what is known to .the `trade technically as a stick of braid by the operator cutting it off and turning one end under.. To start the machine again, the .gear-wheel C is turned back just enoughy to release the hook i of the pin g from the projection b of the cam b, when the shaft a is pushed forward, so as to raise the end of the pin g upon the cam I), for repeating the operation of lapping and measuring a piece ofihraid, as before described. v

Having thus described my inventi on,I claim as new, and desire to secure by Letters Patent* 1. lhc machinery for measuring and lapping braids, tapes,-&c., having a shifting and4 positive stopmotion, substantially as heroin described.

2. The sliding-shaft a, the spring c, thevpin g, and the cam b'on the gear-wheel C, combined and operatingY substantially as and for the purposes herein described.
