roll and which serves to nip the fabric between said nip-roll and said feed-roll. Below the feed-roll. there is a pair of supple mental feed-rolls, one of which is a driven roll and the other of which is a spring pressed nipsroll, whereby the fabric ,is also nipped between said supplemental feedrolls. Vith this eonstructionthe fabric, ,which hangs loose below the supplemental. feedrolls referred to and .which therefore becomes more or less wrinkled `or crinkled at that point, passes, when the, travel of the fabric kis reversed, between the several spring-pressed rolls referredto and their companion rolls in such wrinkled or crinkled condition, which has the effect to press or iron the wrinkles into the. fabric, so to speak, and so that it is very dil'lieult. if not impossible. to thereafter remove them.

A further feature of the invention consists inproviding' means whereby the'several nip-rolls referred to may be moved away from their companion rolls and out of contact with the fabric when the travelof the fabric is reversed. and so that the fabric in tra veling backward will .simply dragl over the companion rolls referred to, and so that the wrinkles in the fabric, instead of being,r pressed or ironed into the fabric, will be smoothed or ironed out by beingthus dragged over these rolls and without being nipped at such points.

A further feature of the invention consists in providing a` brake or drag for the feed-roll. with means for applying such brake or drag to said feed-roll when the travel of the fabric is reversed,

'lhe invention further consists in certain combinations and arrangements of parts hereinafter described and claimed. A

Referring to the drawings, Figure l is a side elevation of the forward end of the ina-- chine and showing the parts in the position which they occupy during` the forward feed of the fabric. Fig. 2 is a similar side elevation of the for\ 'ard end of the. machine, but

The general construction and organization of the machine is the same as that shown in said pending application, and inasmuch as the present improvements are .all embodied in the forward. end ofthe machine, it has been deemed necessary to show in the accompanying drawings only the forward endl ofthe machine in which the several features.of improvement are thus embodied. v

The machine comprises a sultable frame 1 in which the several operating parts are mounted. The-.fabric travels through themachine in the form of an endless web.. The fabric 3 after the race has been cut 1s carried down on to a t-ravellng endless apron or lattice (not shown) at or near the bottom of the machine where it drops in folds, and

in this. form is carried by the travelingfrom.

apron to the rear of the machine.

' the` apron at 'the rear of the machine the l idler-roll. From the feed-roll 14 the fabric passes around the nip-roll 15 and thence fabric is carried up 'over a, feed`roll and down an incline. .At th-e footof this incline the fabric'is'carried upward over two `fixed bars `at the top of the frame. From the `fixed bars at the top of the frame the fabric travels down another' incline 8,` around an idler roll 9, up over a belt driven roll-10, preferably rubber covered, downaround another idler roll 11, then -forward around. a nip-roll 12, and around the drag-roll 13. After passing nearlyV around the entire periphery ofthe drag-roll 13 the fabric is passed around ,the idler rolls 13, '1?b, ar-

ranged as shown lin the drawings, and from' the idler roll 13" the fabric passes to the feed-roll 1l. will be seen, the roll 13h serves to locate the fabric for presentation to the knife, and also serves toi'su'pport the fabric-in proximity to the point of cutting, the knife (not shown) being' located between said idler roll 155- andthe feed-roll 14, and with its cutting portion arrangedto engage the fabric at a point in proximity to said downward between a pair of supplemental 'feed-rolls 16, 17, the roll 16 being beltdriven and the roll 17hffi`ng movable toward and from said roll 16 vand acting as av niproll, and 4thence'down 'on to the. traveling apron above referred to.- l

'.l`he necessary tension at the cuttingr point lis producedby means of the rolls 13 and rl`he feedroll 14 is positively driven,-

lfl'. while the .drag-roll 13 is provided with fa friction .device whereby a friction or drag may be .put on said roll.

rI'he main driving shaft 19 is provided with a pulley 20V driven. by a belt 21 leadi'uiiglm from a motor. or other source of -pmverz On the-opposite end of the driving shaft lflis 'a pulley 22 from which a belt 23 extends to a'pulley 24 on the left hand end of the feed- V roll 14. l On the driving shaft 19 adjacent to the main'driving pulley 2O is a pulley .from which cross belt 26 extends to a loose 'pulley 27 on the feed-10H14.. The

pulley 27 is a two-step cone pulley, and from roll 10. Thus,

the right hand end of saidroll 10 are two' pulleys 36v and 37. .From the pulley 36 a.

belt 38 extends to a pulley on the right hand end of a feed-roll, which is located at the hi-pper rear end of themachine.

Pivoted to the clutclrlever 48 is a latch bar 68 provided with a shoulder 69 adapted 4 to engage the bracket 70, through a slot in which bracket the end of, the latch-bar G8 extends. When the clutch 47 is thrown in to connectthe pulley '22 with the shaft 19,

the upper end of the'clutcli-lever 48 is moved away from the bracket 70, and so as to draw the latch-bar 68 outward and into a position "where the shoulder G9 on said latch-bar will It is desirable in machines of this charac i ter to provide means to reverse the machine and the travel of the fabric, in orderthat if thev knife should Hyout of the race, or any other `accident happen, the fabric may be' run back a short distance for the purpose of reinserting the knife inthe race. This reversal of the machine is effected by-means of the erossLbelt 2G running on one of the steps of the cone-pulley 27 on the feed-roll 14.

This` cross-belt 2G isdriven by the pulley 2 5 which is loose on the main driving shaft, but which is provided with a clutch 71 adapted tobe operated by a lever 72 for clutching said Vpulley to said driving shaft. Preferably a spring 72 is connected to the lower end of the clutch-lever 72 acting in a direction to throw out the clutch 71, and an .adjustable Stop 72b is provided to limit the movement of said clutch-lever under `the aetion of said spring.

When the fabric is caused to travel backn ward it is desirable vto provide a brake or drag vfor the feed-1101114, and in the present .construction suchv a brake or drag is provided with means for controlling thesame by the movements of the handdever 78. The

I brake 122 is pivoted to the frame at 123 and is curved to iinderlieitlefeed-roll 14, as

i shown in Fig. 1./"The movement of said brake into and out of engaging position is :effected by a pair of toggle-levers 124-, 125,

A connecting When the fabric is being the free end of the brake 122 and the lever 125 being pivotally lconnected to the frame. rod 126 connects the lever l with the arm 86 of the hand-lever 78.

The operation of these parts is as follows: fed forward and the lever 78 is in the position shown in Fig.v

`1, the toggle levers 121 and 125` are broken' v.and the brake 122 is out of engagement with the feed-roll 14. When now the fabric is to be caused to travel backward and the lever 78 is pulled forward into the position shown in Fig. 2, ther movement of said lever through the connections referred to serves to straighten the toggle levers and thereby f force the brake -122 upward and into vengagement with the feed-roll.

The voperation ofthe several parts has been already sufficiently described, and `it will not be'necessary to repeat such descripytra tion.. 1t will 'be seen that when the lInacliin'e is to l-be vrun in the reverse direction and the fabric thus caused to travel backward, the proper manipulation of all the parts. for this purpose is effected solely lby Y the movement ofthe l1and-lever 7 8, and that when said hand-lever has been so moved all ythat remains to be done is simply to depress the foot-treadle 5G, thereby throwing in the.

Wn -in V2 the link 119i vfabric as the same is performed, viz., the sliding rod is moved into proper position to engage the latchbar 811 connected to the reversing clutch' i to move toward the roll. 10 and to nip the fabric between said rolls;-the binding rolls 12, 15, and 17 areea'ch moved .away from their companion Vrolls, and 'the fabric released 'at each` of'said points; and finally the brake is applied to the feed-roll.k Thus :when the machine is reversed for the hackwardtravel of the fabric, the movement of thehanddever referred to serves to release the fabric at the lseveral points where it was nipped during theforward feed, and also serves to nip the fabric at the/driven roll locatedat the rear of the drag-roll, and so that the backward travel of the fabric will be caused by the reve-rse rotation of lsaid driven roll. As said driven roll is llocated at the rear of the drag-roll there isno jliabilit of any slack between said rolls during the lloackward travel of the fabric. '.It will be further seen that as the nip of the fabric' is released at thefeed-roll and at the supplemental feed-rolls locatedv below the same, any wrinkles which may form in lthe fabric as it lhangs-loose below said feed-rolls, in-

n stead of being 1ro-ned or pressed into the the lever 124 being pivotally' connected to fabric, will be smoothed or ironed out of the about which it passes. l f
