AUTOMATIC FEEDER.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed March 21, 1919. Serial No. 284,006.

'10 all whom it may concern:

Be it known that I, MAX PoE'rzsoH, a citizen of the United States, and a resident of Clifton, in the county of Passaic and State of New Jersey, have invented a new and Improved Automatic Feeder, of which the following is a full, clear, and exact description.

This invention relates to feeding devices, and particularly to an automatic feeder for various kinds of machines, asfor instance drying, tentering, selvage neutralizing and carbonizing machines.

The object of the invention is to provide an automatic feed which willcause an auto .matic adjustment of the various parts whereby the cloth as it enters the machine will properly engage the pins, clasps, or other cloth engagingmembers so that'the cloth will be stretched, dried, and otherwise operated upon without any action on the part of an operator.

Another object of the invention is to provide an automatic feed which will auto matically shift the cloth'engaging members as described so as to properly engage the cloth and cause the same to fit into the machine in a proper manner and will sound an alarm in case the cloth gets beyond the control of the mechanism. 7

A still further object of the invention is to provide a feeding device which is readily applicable to various machines now on the market and which may be also adjusted for various widths of cloth.

In the accompanying drawings:

Figure 1 is a fragmentary side view of the front part of a tentering machine showing an embodiment of the invention applied thereto.

Fig. 2 is a fragmentary front view of the structure shown in Fig. 1, with the invention shown in operative position thereon.

Fig. 3 is an enlarged fragmentary sectional view through Flg. 2 on line 33.

Referring to the accompanying drawings by numerals, 1 indicates the frame of a tentering machine, which machine maybe of any desired type and supplied with the usual chain 2 having needles, pins or clamps 3 for engaging the edge of the cloth so as to move the cloth through the machine and stretch it at the same time. As the tentering machine is old and well known no particular description thereof will be provided, especially as the invention resides merely in the automatic feed therefor, which will cause the cloth to be properly fed to the needles 3 without the use of an operator. The members 3' on the drawing have been shown as needles or pins, but it will be evident that clasps, hooks or any other desired form of cloth engaging members may be used without departing from the spirit of the invention.

In producing a structure of this kind a reciprocating rod 4: is provided as shown in Fig. 2, guided by any suitable guide and continually reciprocated by a link 5 eccentrically mounted on the rotating disk 6, wherebyas said disk rotates during the operation of the machine the back and forth movement of rod 4 will be maintained. This rod may freely move back and forth, but cannot rotate. Adjacent the opposite ends of this rod, sets of teeth 7 and 8 are provided, the teeth at each end facing in opposite directions so as to engage at the proper time a locking plate 9, which plate is preferably a disk except for the cutaway portion 10, whereby the bar may slide suffi ciently near to be engaged by the projections 11 and 12 when the disk is turned. It will be noted from Fig. 2 that the teeth 7 and S on bar 4 are arranged so that the teeth 7 at the right end will face to the right and at the left will face to the left, while the teeth 8 at the right end will face to the left and the teeth 8 at the left will face to the right. This arrangement is provided so that when the disk 9 engages the teeth 8 from -either end of bar 4 the disk and the parts comiected therewith will be moved inwardly toward the center, while if the disk 9 engages the teeth"? on either end of the bar all of the parts will be moved outwardly or away from the center of the machine.

The disk 9 is loosely mounted on a shaft 13 which is connected with the side walls of a housing 14, which housing is rigidly secured in any desired manner to the sub stantially U-shaped bar 15, as for instance by screws 16. Bar 15 may be-supported in any desired manner on the frame 1, and in is provided with a slot 20 through which a pin 21 extends, said pin being connected with the plate 22 formed integral with disk 9. The disk 9 would ordinarily move down pivotally under the action of gravity until the projection 12 should engage thev tooth 8 but for the action of the cloth entering the machine. The cloth in passing over the teeth 19 of bars 18 and 22 engage the same somewhat, namely sufficiently to hold the projections 11 and 12 out of engagement with bar 4. The selvage of the cloth has a less tension than the body of the cloth so that when the cloth is being properly fed into the machine the selvage scapes overthe teeth 19 and merely holds the parts in position as shown in Fig.3, but in case the cloth should move too far over on to'the teeth the body of the cloth would engage the teeth and being tighter would swing the plates, including the disk 9 upwardly nntilthe projection 11 was in engagement with oneof the teeth 7. movement in a direction away from the center of the'cloth. This lateral movement is communicated, of course, through'th'e frame 14 to the U-shaped bar15 and from thence" through 'the 'arm xtl tomeniber 39' and also to the yoke 42 which fits into the groove in the hub of wheel 40" whereupon the sprocket wheel 40 and the chain 2 carried thereby are Inovedtothefedge of the cloth so'that they will engage only the s'el' vage. The same operation takes place on both sides of the machine so thatthe'cha'ins 2 the plates 18 and 22 the tension of the cloth" would cause an engagement with the teeth 19 so that the plates 18 and 22 would swing upwardly and rotate the disk 9' a suiiicient distance to cause the extension 11 to engage one of the teeth 7 on bar 4. hen this takes place the bar or rod 4 will pull the plate 9 and associate parts including arm 41 so that the sprocket wheel 40 and the chain 2 carried thereby will be moved to a position beneath the sclvage, the movement being in a direction away from the center of the machine. The pulling action provided by this mechanism will be repeated until the ma chine has been moved to a proper position for the pins or needles 3 to engage the selvage. This occurs on either side of the machine as may be necessary. In case the cloth This would cause a lateral- Laramie moves toward the center of the machine and consequently moves entirely off of the teeth 1.9 plates 18 and 22 will drop downwardly and thereby rotate the disk 9 so that the projection 12 will engage one of the teeth 8. As bar 4 is continuously moving this will cause bar 18 to move plate 9 and all parts associated therewith including arm 41 and sprocket wheel 10, the movement being toward the center of the machine. This movement is repeated until the needles 3 are brought beneath-the selvage.

As the cloth being fe'dinto the machine is arranged in apile or on a roll at a given point adjacent the machine the movement of the cloth will naturally be very small and consequently the adjustment of the machine will be but small, but in any event the needles 3-will' follow the selvagein either direction and'thereby not in anyway damage the cloth, while at the same time automatically acting to engage the cloth at the right point. It';- i"s,'-of; course-, to be understood that aftcr' the selvage has been hinged on the needles 3,01 otherwise engaged by the members carried by the-chain's 2' it will move into the machine and become stretched in the usual manner determined by the way the 'i'naehine' is set;

As theclbth is fed into the machine it passes through suitable guiding shoes 23 and 24 pivota=l-ly mounted on arms 25 and 26-, which arms are rigidly secured to sleeves 27 and 28. These sleeves and associate parts are identical, so that the description of one willap-ply to both. A post 29', for instance. is connected with the sleeve 28', said post having an arm 30 pivotally connected therewith, said arm havinga pivotal bar 31 as shown in Fig, 1, which bar in turn carries a roller -32. Adjustable contact members 33 and 34 are connectedto the bar 31, and suitable electrical connections are connected with these contact members, said connections being also connected with a sounding device, whereby when these contact members are brought together the current will be closed for'operating the'sounding device, which may be any desired kind, as for instance an'ordinary electric bell. These contacts are held apart by the weight of the roller In case the cloth should move over to a position beneath the roller said action will raise the roller 32 suiiiciently to cause the contacts tobe engaged, whereupon the alarm will be sounded and an attendant may come and're-adjust the machine if same is desirable, thougliordinarily the bar 4, plate 18 and associate parts will re-adjust the machine auton'iatically.

As another safety appliance, a second alarm is connected to the contact points 35 and 36. Contact 36 is connected with a stationary post 37, which may be supported in any suitable manner, as for instance by a bar 38 secured to the supporting frame 39. i-This frame in turn is supported by suitable anti friction means and-atransversebar 40:";Th movable contact '35 lSCOI1I16Ct8(1j-i;0 l7lI6 swinging feelerbar '35=', :which -is pivotally mounted on the post 37', and'normally rests on the cloth rollimmediately above the needles so that when'theclothmoves oif of the needles feeler 35- will zswingi downwardly under the action of 'gravit'y-andmove com tact 85 into eng gement with contact 36 for sounding'analarm I v When any-operator inthe viciiii'ty'hears either of the alarms above mentioned'they are supposed to look the feedingapparatus over and re-adjust the cloth or the machine if the same is necessary. By the mechanism j ust, described alarms are sounded when the cloth'mo'ves laterally in one directiomor lat erally in another direction. -"In"-"=additio1i mechanism has been provided for actually pulling chains adjacent either edge, where'- by the chain is automatically maintained in the proper feeding-position for the needles 3 to engage the seli age as the cloth enters the tentering machine. Heretofore one, two or more operators were necessary to feed the cloth into the tentering machine in order that the needles would engage the selvage properly, so that the cloth could not only be dried, but stretched during the drying action, and thereby caused to assume the proper shape and to present the proper appearance. It will be noted that when a strip of cloth is passed into the machine properly none of the automatic mechanism is operated except rod or bar 4, which continually reciprocates at all times. If the cloth moves to either side one of the plates 18 or 22 begins to pull the chain back and if the movement is appreciable one of the alarms will be sounded. The par-ts are set, preferably, so as to give the automatic part of the mechanism a chance to adjust the chain, but the signals are arranged to sound before the cloth has moved to one side a sufficient distance to do any injury.

Heretofore usually two persons were used to feed cloth into one tentering machine, but with this automatic structure for shifting the chain back and forth one attendant may cause the feeding mechanism to properly operate in a number of machines,

or rather oversee the feeding of a number of machines. It is, of course, evident that the feeding arrangement may be adjusted back and forth to take care of different widths of cloth, which is also true of the centering machine forming no part of the present invention.
