SEAM-DAMPENING MACHINE.

T 0 all whom it may concern,

Be it known that I, BENJAMIN K. An.

snncHT, citizen of the United States, residmg at Rowayton, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in, Seam- Dainpening Machines; and Ido hereby declare the following to be a full clear, and] exact description of the invention, suchas will enable others skilled in the art towhich it appertaius-to make and use the same.

My invention relates to improvements in machines for dampening the seams of collars preparatory to bending the flap.

Fig. 11 is a broken View of a collar showmg the operative position of the feed wheels and guide rolls with respect to the collar during the dampening process; and

Fig. 12 is a broken view of a collar after leaving the guide rolls and where the collar is guided through the, feed rolls by means of a finger projecting from beneath the upper surface of the bed.

The feed roll shafts l and 2 carry the feed rolls :3 ands located with respect to, the machine bed 5 as shown in Fig. .7. .The shaft 1 carries the gear 6, Fig. 2,}to mesh with the gear 17 .on shaft 2. 8 is the continuous running driving pulley whose hub 9. Fig. 5, isrotatively mounted on the hub 10 of the gear 6. This pulley is cupped out to embrace and protect the gears which would other-wise be exposed and an accidentliable to result thereby. Motion is ,communicated from the pulley to the shafts by forcing the pulley against the intermediary friction washer 11, Fig. 2. This force is .effected by meansof the starting lever 12 with its lower endpivoted towthearm 13 and its intermediate portion embracing the hub of the pulley with the pins l l, Fig. 5,-engaging the slot 15 formed in said hub as shown in Fig. 2. 'l6.is a springcatch adapted tolock the lever in its advanced operative position.

The shaft 2 has .also a vertical movement or adjustment to adjust the distance between the feed rolls by reason of its passing through the block 17, Figs. 1 and 6, whose journals '18 are mounted to rock in the standard 19 secured to the machine bed. 20.

tionate to the position it occupies on thebar; The bracket 23, mounted on the standard 19,

carries the adjusting screw 2%: engaging the outer endof bar 20 to tilt the-shaft 2, I

and adjust the position 'offlthe feed 'roll 3 with respect to the lower feed roll l.

.25 is a sleeve journaled on the innerend oftheshaftl2 and 26 is an ;arm projecting therefrom and it carries theguidel roll mechanism comprising the hub 27 having theuprights 28 having the inner projections' 29 adapted to register with grooves formed in the arm '26,one of said grooves 30, is shown in Fig. 7,whereby the position of said hub is adjusted on said arm and is secured in any of its adjusted positions by the screw 31, Figs. land 6.

32 is a rod adjustably mounted in the hub 27 carrying the guide rolls 33 and 3t. The roll 33,. Fig. 9. isrotatably secured to the end of rod 32 by the screw 35. The roll 3% has the hub 36 rotatably mounted on said rod and is backed up by the spring 37 for the purpose presently to be more tullyerr plained. v

38 is a water tank mounted on the support 39 and said support is rotatably mounted on the 'arm etO,' which arm is adjustably mounted on the arml by means of the slot 42 and screw/t8, Fig. 6. at-i is a screw passing through a threaded hole in the lower arm 41 and also througha centralthreaded hole'in the busing t5 and contacts with the bottom of the standard $6 and thus adjusts the height of the water tank when the screw 47 is loosened; and. at the same time. the

'water tank can be horizontally adjusted orswung to one side.

v i V y l 1 48 1s a rod whose .upper end 1S pivotaliy I connected to thelever e9 pivotally support ed on the forked stud 50 FigLQ-fi', on top or thetank. The opposite end of this lever is pivotallysupported in theupperitorked end of the vertical rod 51 within the tank whose lowerend is pivotally supportedon one end of the lever Fig. pivotally mounted on the forked stud 53. This lever carries the valve 54: covering the opening tothe dis charge spout of the tank; The free end of therod 48, Fig. 1, carries the pin 58 adapted to be'engaged by illleiilllll 30 when a collar is i isert-ed. under the guide rolls 33-43%, and thus lift the valve 5% Within the tank and permit the "water to be discharged on the upper feed roll. The height of the pin from the arm 30 can .be adjusted for different thicknesses of collars by means of the setscrew 5'7. The same lifting effect of the valve is produced in the modified con-X struction shown in Fig. 10 where the lower stem 58 of the valve carries the small wheel 59 in close proximity to the upper feed roll sothat when a collar is inserted between the feedrolls, thevalve is opened bythe contact of the feed roll'with the wheel 59. The

be done. It too much water is used it will spread out beyond the bend ng point and destroy the gloss or finish previously imparted to the collar. It insuthcie'nt water isused, or the water is not'applied tothe upper teed before said roll contacts with the collaig-the" starch is simply broken up due to lack moisture. Y

means ofthe arrangement of the meh anism pre 'iously described, I am not only As the collar is first entered oughly covered with waterbefore the collar enters the feed rolls. Thereforefthepre terred arrangement for actuating the water supply is from the guide roll arm rather than from the'upperfeed roll as shown in Fig. 10. is the collars are passed rapidly through themachine, it is evident that when the valve is actuated by the insertion of. the collar between the. feed rolls it will havead- While onthe other hand, as betore mentioned, the valve is actuated inadvanceof the entrance o'f'the collar between the feed:

rolls by the arm 26.

When the collar'has guide rolls; Fig. 12, the plate .60 is released to bring the guide finger above the bed and against the edge 74 of the tab 75'to maintainthe seam of the collar against the face or" the upper teed roll until the collar is' clear of the feed rolls.

To ettectthe required working 'pi'essureiot' the guide. rollsagainstfthe collar, the triotion washer 76, Figs. 1 andb, is placed between the adjustingiscrew 77 and the outer end of the sleeve The swinging cover 'TS'covers an opening not. shown-nu. the top admission of water. Y In practice the position ofthe guide rolls with respect to the feed rolls and collar will advanced clear ofthe of the tank for g the vanced a considerable distance before the water can reach-the surface of the collar.

be such that the valve in the tank will be open during the entire time that the feed rolls are in contact with the collar.

Having thus described my invention, What I claim is 1. A seam dampening machine comprising two parallel feed roll shafts, gears connecting the shafts, a continuously running driving pulley rotatably mounted on the hub of one of the gears with its rim embracing the gears, and means for bringing the pulley in frictional driving engagement with the gear on Whose hub the pulley is mounted.

2. A seam dampening machine comprising an upper and lower feed roll shaft, means for rotating said shafts, a sleeve journaled on the upper shaft having an arm projecting therefrom, guide roll mechanism adjustably mounted on the arm, an overlying Water tank having a delivery nozzle or outlet overlying the upper feed roll, a valve above the outlet, and means connecting the valve With said arm so that said valve is raised when a collar is inserted under the guide rolls and Water supplied to the upper feed roll before said feed roll engages the collar and during the engagement of said feed roll with the collar.

8. A seam dampening machine comprising upper and lower shafts, feed rolls on said shafts, a sleeve journaled on the upper shaft having an arm projecting therefrom, a hub adjustably mounted on said arm and in advance of the feed rolls, a rod adjustably mounted in the hub, independently operating guide rolls rotatably mounted on said rod and under spring tension to accommodate for difierent Width of seams.

In testimony whereof I affix my signature.
