HARRISON GARNEIT, OF NORRSTOWN, FENNSYLVANIA.

Original application filed September 14, 1921, Serial No. 500,518.

rarest No. 1,431,449. Divided and this application filed August 21, 1922. Serial No. 583,458.

To all whom t may concern:

Be it known that I, HARRISON GARNn'r-r, a citizen of the United States. residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Improved Measuring and Marking Device for Beaming Frames for Looms, of which the following is a specification.

My invention relates to devices used for automatically measuring and marking off certain lengths of yarn or warp as it is wound onto a loom beam from a reel or other source. The length marks may be made on the warp at required or predetermined distances for instance every forty, sixty or any other number of yards.

While my improved measuringr device may be used in connection with all kinds of beamingT frames or other similar machines, yet it is especially adapted to be used in connection with Lthe combined beaming frame and press for looms for which an application for U. S. patent was filed September 14:, 1.921, under Serial #500518, of which this application is aI division.

My invention consists of the combination of a drum having a certain diameter and upon which the beam receivingr the warp is loosely mounted or pressed, and mechanism operated from the drum shaft to actuate a chalk-cup at predeterminated intervals.

My invention will be more fully understood. taken in connection with the accompanyinnr drawings in which:

Fig. l is an elevation of a part of a beamingr frame and showing the measuring device applied thereto, and

2 is an end view of Fig. 1.

Referring now to the drawings for a further description of my invention, D is a drum of wood or other suitable material and having a shaft d fastened to the drum; the shaft is journalled in standards and is driven by suitable gearing not shown. On top of the drum is loosely mounted in slotted bearings b3 the beam B, and this beam receives the yarn from a reel not shown. in the usual or any preferred manner, and in its travel it passes over the rod or shaft e.

0n the drum shaft Z is secured a crosshead mf. in which one adjustable pin m1 is secured. to oscillate the lever 'm2, hinged at m3 and held back by the spring m4. At the upper end of the lever m2 is adjustably secured a pawl m5, which engages a ratchet wheel `m6 having anumber of teeth. A pin m7 in the face of the wheel m6 is provided to tripa lever m8 once at every revolution; and this lever fulcrumed in a slotted connection at m has a chalk cup m10, which may be raised or lowered by turning the two nuts m11. Whenever the lever m8 is tripped, the chalk-cup m10 is thrown up against the passing warp and leaves a mark on said warp.

The operation of my device is as follows: The drum is preferably made to measure two yards in its circumference and therefore as it makes one complete revolution two yards of yarn have passed from the reel onto the beam B. The crosshead m shown in Fig. 2 is provided with only one pin fm1, and the lever m2 with pawl m5 is therefore actuated only once at every revolution of the drum D, if now the ratchet wheel me has forty teeth then the pin m7 will trip the lever m8 once in forty revolutions of the drum or after 80 yards of yarn have been wound onto the beam B. If the passing warp is to be marked every 4() yards another pin m1 is inserted in the crosshead m or another pin m7 in the face of the wheel me; and if any other number of yards are to be marked off, another wheel with the required number of teeth is used as will be readily understood.

It will be understood by those skilled in the art that modifications may be made in the arrangement and use of other mechanism without departing,r from the spirit of the invention, and having thus fully described the nature and objects of my invention what l claim as new and desire to secure by Letters Patent is:

1. In combination with a beamingf frame for looms having a drum, a measuring and marking device comprising' a ratchet wheel liournalled on a stud of the frame, a lever with chalk-cup adjustably pivoted also to the frame, a pin or projection on said ratchet wheel to trip said lever, and means to rotate said ratchet from the shaft of said drum.y ubtantially as and for the purpose set orti.

2. In combination with a beaming frame pawl on the other end of said lever, a spring i to hold the lever towards the said pin, a ratchet wheel pivoted to a support and actuated by said pawl, a pin in one face of the ratchet wheel, and a tilting lever having a marking cup and operated by said pin at each rotation of said ratchet wheel, substantially as and for the purposes set forth.

3. In combination with a beaming frame for looms having a drum, a shaft lixecl to and rotating` with said drum, a beam to receivethe warp and resting on said drum, a measuring device for said warp consisting of a tilting lever adjustably hinged to a support, a challocup on one end of said tilting 15 `fiver, a ratchet wheel, journalled on a fixed HARRISON GARNETT.
