GEORGE GOLLIS, 0F DUBUQUE, IOWA, AS SIGNOR TO THE COLLIS COMPANY, OF DUBUQUE, IOWA, A CORPORATION OF IOWA.

FABRIC-SINGEING MACHINE.

'1' '0 all whom it may concern:

Be it known that I, GEORGE CoLLIs, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Fabric-Singeing Ma chines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to fabric singeing machines and more especially to those of the class which are adapted particularly for singeing hosiery and the like.

The object of my invention is primarily to construct a machine of the characterspecified which, though comprising a comparatively few parts and mechanisms, yet is capable of rapid operation, and this without the usual danger of the fabric being burned or scorched.

Another object of my invention is to provide a machine of this character which is largely, if not entirely, under the complete control of a single operator.

A further object is to provide such a ma chine with means conveniently located for controlling the operation of its parts and mechanisms and, whereby such operation may be carried on practically continuously.

Another object is to arrange the structures so that, for the most part, they extend vertically, and move in a substantially vertical plane, whereby valuable floor-space is saved, and, moreover, the heat and fumes from the machine are located above the head of the operator. a

With these and other objects'in view, the

invention resides in the novel combination and arrangement of parts and mechanisms, all as hereinafter more particularly described and claimed.

In the accompanying drawingswherein I have illustrated an exemplification of my invention as embodied in one form of machine (though it is to be understood that I may employ other embodiments following the general principles of my invention) Figure 1 is a view in side elevation of the machine embodying said embodiment of my invention; Fig. 2 is a similar view, from the opposite side; Fig. 3 is a view in rear elevation of the machine; Fig. 4 is a front ole- Specification of Letters Patent.

Application filed September 16, 1911.

Serial No. 649,726.

vational view thereof; Fig. 5 is a view in plan of the same; Fig. 6 is a fragmentary v1ew in vertical section, taken on the line 6 6 of Fig. 2; Figs. 7 and 8 are enlarged vlews, in perspective and section, of the machlne-drive; and Figs. 9 and 10 are fragmentary views of an upper portion of the machine.

In these drawings, the numeral 1 designates the base or bed of the machine, and 2, 2 upstanding supporting standards or upright-s mounted at one end of the machinebase. It will be understood that these two parts (the base and the uprights) are the main supporting structures of the machine. Said base is only of suiiicient length and width as to'sustain certain mechanisms (presently to be described) because it is a desideratum of my invention to conserve floorspace to as great an extent as possible.

The drive-mechanism (which I shall now describe) comprises a band-wheel 3, loosely mounted on a short shaft 4 suitably journaled in bearings in trunnions 5, 5, extending upwardly from the base, and which wheel is driven. from any suitable source of power, as, for instance, by a motor (not shown) or by shafting (not shown) as may be desired. By means of a train of gears 6 (Figs. 7 and 8) and a clutch-mechanism 7, said wheel may be clutched to its shaft. The clutch-mechanism is controlled bv a lever 8 pivoted on one of the uprights 2 and, through a vertical connecting rod 9, bellcrank-lever 10, and a horizontal connecting rod 11, is adapted to position a pivoted clutch-actuator 12 which is arranged to engage a spring-controlled clutch-pin 13 slidably disposed in the hub 6 of one of the train of gears aforementioned.

Keyed on the shaft. 1 adjacent one end thereof is a crank-disk 14v to which is concentrically connected a reciprocating rod 15. This rod connects at its other end with slide 16 having a rack 16 on itsupper edge. Adapted to mesh with and be driven by said rack is a pinion 17 keyed on a stub-shaft 18 journaled in trunnions- 19, 19, disposed at 'the end of the base opposite the trunnions 5, 5. Carriedby said shaft 18 is a two-channeled drive-wheel 20. It isto be understood that the band-wheel? is a constantly rotating element, whereas said second drivewheel 20 is only intermittently actuated and has only a partial rotation-first in one direction, and then in the opposite, as denoted by the arrows A and B in Fig. l-and this is because the reciprocation of the rod 15 and slide 16 effects a corresponding movement of said wheel 20.

It will now be understood that the structure already described constitutes the drivemechanism of the machine. I shall now de scribe the mechanisms which are driven thereby: Suitably secured to said drivewheel 20 and adapted to be wound upon the same (when revolved in one direction) in one of the channels thereon is a strap 21 which passes up over an idler 22 journaled in brackets 23 secured between the uprights 2, as shown. Also suitably secured to said drive-wheel 20 and adapted to be wound upon the same in the other of its channels (when said wheel revolves in the opposite direction) is a second strap 21 which passes down and over an idler 23 carried by brackets secured adjacent the lower ends of the uprights 2.

The uprights 2, 2, are formed as guides or ways. Adapted to slide up and down thereon is a cross-head 24 of any appropriate form and size but preferably such as that illustrated. To this cross-head, the straps 21 and 21 are secured, as shown. Upstanding from and mounted on said crosshead is a fabric-carrier 25 in the form. of a sustaining member or form, of suitable length to carry a stocking stretched to full length. The structure last described constitutes the stocking-positioning mechanism and is driven by the driving mechanism al ready set forth.

Mounted on the uprights and in the path of upward travel of the stocking-form 25, is a casing 26 open at top and bottom and provided at one end with a flue 27 and containing a series of singeing burners 28 which connect by means of a pipe 29 (controlled by turn-cocks 30) with a suitable source of supply of gas or whatever form of fuel is utilized. The casing is sufficiently elevated from the base to be above the plane of the head of the operator, and the flue thereon is adapted to remove the products of combustion and smoke caused by the singeing of the fabric. It will be observed that there is a series of pairs of the burners and that each of the pairs projects toward its com-v panion burner. In this way, a vertical battery of burners is provided, all incased in the housing or casing 26. A door 31 at one end of the housing permits access to the burners to light or clean them. The supply of fuel to these burners is conveniently regulated by means of the cocks or valves 30, already referred to. It will now be seen that, as the hosiery form is moved upwardly under the action of the positioning-mecluinism, as heretofore explained, it will be projected through the open bottom of the easing and in juxtaposition to the respective pairs of burners and be thereby singed. The casing and its contained burners, etc, therefore constitute the singeing structure of the machine. The upward travel of the hosiery form is not discontinued after it has passed through the singeing structure described. On the contrary, such travel is continued and for a purpose now to be explained.

Mounted at or adjacent the upper extremities of the uprights 2 is a snufiing structure comprising two juxtaposed snuffing rollers 32. Each of these rollers is carried by a stub-shaft 33. The shafts of these two companion rollers are preferably journaled in a bracket 33 mounted on the uprights and extending outwardly therefrom, as shown in Fig. 9. Superposed to these snufiing rollers 32 are two pairs of gripping rollers 34 and 35 carried by shafts 34 and 35 journaled in portions 35 of two twomembered brackets 36 and 36, carried by horizontally-extending arms 37 mounted at the upper ends of the uprights 2. As will be seen by referring to Fig. 9, the inner brackets 36 are fixed on their said arms, while the brackets 36 are adapted to have a limited sliding movement. Such movement is, in each instance, controlled by a spring 38 abutting against said bracket and housed at its opposite end in a socket-member 39. By the arrangement described, the outer series of rollers 34- and 35 is adapted to be spaced from their companion rollers. Such spacing is effected by means of the following structure: A pusher-arm 40 is pivoted at its inner end to one of the uprights and. has its outer end provided with a cammed enlargement 41 adapted to have cooperative engagement with a stud or extension 34:" carried by the shaft 34 of the intermediate rollers. An elongated actuating-rod .42 is connected at one end to said pusher, and, at its lower end 43, is pivotally connected to a bell-crank-lever 44:, to which is also pivotally connected a horizontal arm To this arm is pivoted a link 46 fulcrumed at 47 and carrying at its opposite end a roller 4-8 adapted to travel on the periphery of the crank-disk, already referred to, and upon which is formed a cam 3. As the disk rotates, it will, at one portion of its revolution. cause said cam to engage the roller-provided link 46 .and rock the same on its fulcrum. Such a movement actuates the connecting rods and the intermediate bell-crank-lever to rock the pusher on its fulcrum, and this effects an outward movement of the rollerbrackets and their rollers, whereby they are momentarily separated. They are returned to normal position by the spring 38.

In order to eifect a simultaneous rotative movement of the several rollers described, each is provided with a gear, as 32 and 349, each gear meshing with its juxtaposed gear. These gears are driven by a pulley 49 mounted on one of the shafts 34 and which shaft carries a gear 50 adapted to drive, by a chain-gear 51, the upper rolls. is driven by a belt 52 operated by a suitable power-device (not shown).

The rollers 34 and 35 are designed to pull the stocking off the hosiery-form. When so removed therefrom, a deflector or plate 53 (suitably secured to the extremities of the uprights) guides the stocking onto a belt 5a which passes around the upper inner roller and, also, around a pulley 55 suitably supported on a depending bracket 56 slidably mounted on an extension 87 of the arm 37, and which bracket, under the influence of a spring 57 (encircling said arm and abutting against an adjustable collar 58) tends to maintain said belt taut. Also depending from said extension 37 is an inclined chute 59, onto which said belt delivers the stockings after they have been removed from the hosiery-form, in the manner already explained. This chute feeds the finished stocking into any suitable receptacle (not shown) or the like.

Preliminary to positioning the stocking into and through the singing structure, as explained, said stocking 1s passed between companion brushes 60 and 61 arranged in the path of upward travel of the form. The elements 60 and 61 may be rollers, if desired. Qne of the rollers 60 (and the smaller of the two) is loosely journaled in a bracket underlying the burner-casing 26. The other and larger roller 61, is likewise journaled in said bracket, and is driven by a belt 62 connecting with the source of power of the machine.

Operation: Assuming that the singeing burners are lighted and that it is desired to subject stockings, or the like, to a singeing, the operator moves the control-lever 8, whereby the band-wheel is clutched to the crank-disk. In the manner already described, this actuates the drive-wheel 20 to cause it to have a partial revolution in the direction indicated by the arrow A. Thereby, by means of the strap 21, the cross-head and the stocking-form (with the stocking thereon) are elevated and positioned between the brushing rollers 60 and 61. These serve the dual function of brushing up the fuzz and, also, of acting as a guide for the upper end of the form. The rotation of the brush-roller 61 aids in the fuzz-brushing operation. If desired, this roller may be loosely mounted as is its companion roller. The continued upward movement of the form then positions it in the. singeing structure wherein the fuzz is singed off. The further upward movement Said pulley of the form then positions it between the shutting-rollers whlch are so formed and constructed as to snuff out any ignited part of the surface of the stocking. The form will then move to its limit of upward travel and, thus, will have carried the stocking between the uppermost rollers which then operate to pull it off the form, whereupon, by the aid of the deflecting plate, it is guided onto he conveyer-belt and thence onto the chute. During this entire upward movement of the form and its stocking, the drive-wheel will have been revolving in the direction of the arrow A, as aforementioned. In the interim, the cam 8 on the periphery of the crank-disk will have caused the op eration of the roll-separating mechanism, as already described, and, thus, effected a separation of the snuffing rollers, etc. And this will have been effected just at the moment that the stocking is to be passed be tween the snufiing rolls and just before it is to be drawn off the form. By this automatic and predetermined separation of the rollers, the stocking-covered form is not made to force the rollers apart because, if it did, the fabric of the stocking (and, especially, if the stocking is of fine goods) would be broken at the toe and the form roughened. As soon as the form has passed between the rollers, they are permittedby reason of the position of the separatingmechanism, as controlled by the cam on the crank-disk -to close upon the fabric so that, when the hosiery-form begins to move downwardly, the stocking will be held from similarly moving downward with the form; but, under the action of the conveyer-rolls, it is caused to travel upward and, finally, is delivered onto the conveyer. When the form has reached the limit of its upward travel, the rotation of the drive-wheel 20 is reversed and, in revolving in the direction indicated by the arrow B, causes the drive 21 to draw downwardly on the cross-head, and thereby it and the form will be lowered to starting position. The operation is then continued as before.

It will of course be apparent that, instead of moving said hosiery form-or carrier, I maymake it stationary and move the singeingvstructure, snuffing device, etc., in relation to it. This can be accomplished by mounting the same so as to slide on said uprights, similarly as does the cross-head and form.

It is'a feature of my invention to carry on the operations hereinbefore described by moving the stocking in a substantially vertical plane, as distinguished from the usual manner of doing this, namely, either in a horizontal plane or by a rotary travel of the stocking. By reason of the particular way in which I accomplish these movements,the entire stocking is subjected to the singeing operation and at a predetermined speed.

My machine is, of course, adapted for singeing fabrics other than hosiery and the like.

While I have herein described my invention in detail, it is to be understood that the same is none the less susceptible of variation and modification; and I do not, therefore, limit myself to such details except in so far as they may be specified in the claims.
