I TAKE-UP MECHANISM F A LOOM.

' To all whom't't may concern:

' 'Be it known that We, LAWRENCE B.

JENoKEs and EPPA H. Bron, both citizens of the United States, residing atXVorcester, 1n the county of Worcester and State of Massachusetts,' havejointly. inventedc'ertain new and useful Improvements in a Take- Up Mechanism of a Loom,' of which, the following is a specification.

' Our invention relates to a take-up mech.

' anism of a loom, and the object of our invention is to improve upon the take-up mech anism as ordinarily made, and more particularly to provide, improved means for disconnecting the gear of the cloth-roll from either one of the other gears of the take-up mechanism, and'also to provide an improved friction drive forthe gear of thecloth-roll.

Our invention consists in ce 'tain novel loom sufficient to illustrate our: improvements applied thereto.

Referring .te'the drawings Figure 1 is a rear view of a take-u mechanism with our improv znentsa'pplie thereto, looking in the .tion of arrow 1), same figure.

direction of arrow a, Fig. 2. Fig. 2 is a sec: tion, on line 2, 2, Fig. 1, looking in the .d-irec- Fig. 3 shows some of the parts shown in Fig. 2, detached, and in an opposite position; the loom frame is broken away inthis figure, and, Fig. 4 is a section, on line 4, 4, Fig.3, looking in the direction of arrow '0, same figure, showing the-friction drive for the cloth-roll.

In the accompanying drawings, 1 is a detached portion of a loom frame end or side,' 2 is the breastbeam, 3 the take-u roll fast on the shaft 4 mounted in suitable iearings 5 on the upright frame 6, secured at its upper end to tie breast-beam 2, and at its lower end to a transverse bar on the loom, not shown.

7 is a gear fast'on the take-up roll shaft 4,

v which shaft is operated through a gear not shown on the other end thereof, by a train of gears, and a pawland ratchet, operated from some moving part of the loom in the usual way. On the shaft 4 of the take-up roll 3, in this instance between the hub of the gear '7 and the bearing 5 of the shaft 4, is in this instance looselymounted the hub 8 of an arm 8, having an elongated slot 01' opening Specification of Letters Patent.

. S." theretlirough, to receive a stud 9 on which is loosely mounted a gear 10. By meansof the elongated opening 8" in the arm'8, the stud 9 may be raised or lowered therein, to adjust the p'ositionof the gear 10, and then secured in an adjusted position by means of anut 9,see Fig.1.

The swingingarm .8 has aside extension 8 thereon, and extending down from, and in this instance integral therewith, is an has secured 'thereto a stud- '11, which is adjustable in an elongated'opening in theextension 8, and is secured in an adjusted,' position by the nut 11', see Fig. 1.

The stud 11 has loosely-mounted thereon V the hub 12 'of,a latch 12. The latch 12 has an engaging end or rejection 12"- to operate said latch, and said atch has in this instance an opening 12' therein, with two recesses 12'? leading out therefrom, to receive a stationary stud or pin 13 secured to the stand 6. a On the swinging arm 8 is an adjusting crew or bolt 14, turning in a lug 8 on said m, and adapted to engage with its inner 'end the outer-edge of the" stand 6, as shown in Fig. 2, to'li nit the inward movement of the swinging arm 8.

Extending in the same vertical plane as the gears 7 and 10, is a third gear 15,' in this instanceloosely mounted on an extended end i p The gear of the shaft16 of the cloth-roll 1 7. 15 is in this instance yieldingly attached to the shaft 16 in a rotary direction, by a disk 18 splined on the shaft 16, see Fig. 4, and a four spring 19 having its hub 19 also splined on the shaft 16, and bearing against a bearing 20 for the shaft 16, see Fig. 1. The spring 19'fore'es the disk 18 against a friction surface 15 on the gear 15, and the revolution of the gear 15, through its frictional engagement with the disk 18, rotates the shaft 16 and the cloth-roll 17.

of a nut 21 turning on the, threaded end of the shaft 16. The nut 21 bears'against a collar 22, loosely splined on the shaft 16,

and'intermediate then'nt '21 and the hub of 105,

the gear 15. A pin 23, actuated by a spring 24 which extends within a recess within the nut 21, has a tapering end which extends within a correspondingl shaped recess in the collar 22, and acts to ho d the nut 21 in 110 65 'operating handle 8 The side extension 8 position after adjustment, and prevents it from becoming loose onthe threaded end of the shaft 16. There will be'a series of recesses 22inthe collar 22 to receh e the pin 23.

By mean'sof the swinging arm 8 carrying the gear 10, the gear 10 may b moved into mesh with the 'gear as shown in Fig. 2, to

drive said gear, through the rotation of the gear 7 and the gear 10, and is held in mesh by the latch 12 engaging with the pin 131, as shown in Fig. 2. By means of said swinging arm 8, the gear 10 may be moved out of mesh with the gear 15, the engaging end 12 of the latch 12 being depressed to raise the inner end of the latch and disengage the outer recess 12 from the stud l3, and allow the inner recess 12? to engage with said stud 13, as shown in Fig. 3, and hold said gear 19 out of engagement with the gear 15, so that the cloth-roll 17, through the handle 17 thereon, see Fig. 1, may be turned fr aly in either di-', rection.

, The advantages of our improvements will be readily appreciated by those skilled in the art. They are of simple construction and operation, and may be readily applied to loom take-up mechanismsof ordinary construction. By means of our improvements the cloth-roll can be readily disconnected from, and connected with its operating gears. It will be understood that the details of construction of our. improvements may be varied if desired. 4

Having thus described our invention, what we claim as new and desire to secure by Let I ters Patent is -1, Ina take-up mechanism of a loom, the combination with the cloth roll shaft, of a friction clutch member. attached thereto, to

move lbngitudinall y thereon and rotate therewith, a spring for moving said clutch member in the direction of the length of the shaft, a

second clutch member loose on saidshaft and in engagement with the other clutch member,

one of said clutchmembers being a'drivengear, and means for regulating the frictional engagement-between said clutch members,

said means com rising a nut turning on the threaded end 0 said shaft, and carrying a spring actuated. pin extending in a p1ane parallel to said shaft, and the engaging end of,

said' pin adapted to enter in a collar loosely frictional engagement between said cutch members, said means comprising a nut turning onthe threaded end of said shaft, and carrying a spring actuated pin extending in a plane parallel to said shaft, the en aging end of'said pin adapted to enter in a collar loosely splined on said shaft, and said collar, intermediate said nut and the hub of one clutch member, said nut and collar located on the opposite. side of the clutch members from the actuating spring.

3. In a take-up mechanism of a loom, the combination with a driving gear on the takeup roll shaft, and a driven gear on the clothroll shaft, of an intermediate gear, and a swinging arm for supporting said intermediate gear, said arm adapted to be moved to carry said intermediate gear out of mesh with one'of the other gears, or into mesh with one of said gears, and means for moving said arm and means for locking it inposition, said locking means comprising a pivoted latch to he moved by the operator and engage a stationary pin or stud.
