To all whom it may concern:

Be it known that we, Louis LAVEGK and ALPnoNsn M. ROY, citizens of the United States, residing at Fulton, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Machines for Removing Corset- Steels and the like, of which the following is a specification.

This invention relates to machines for re moving corset steels, and the like, the steels being exposed by grinding off the layer of fabric covering them by means of an abrading device comprising a belt or drum or revolving roughened surface of suitable character, against which the corset is fed. This invention also comprises means for spreading the fabric fiat upon the feeding table or bed. The abrading device is caused to move more rapidly and in the same direction as the feed roller, and mechanism is provided for the purpose of drawing the fabric, after being subjected to the abrading device, in one direction while the uncovered steels or stiifeners are directed and removed in another direction. Thus, the fabric and the steels are separated by the operation of this invention.

0f the accompanying drawings illustrating the construction and arrangement of the parts of this invention, Figure 1 represents a side view of all parts assembled, the feed roller and the edge of the table or bed being shown in section on the indirect broken line w-w of Fig. 2. Fig. 2 is a top plan view of all the parts assembled. Fig. 3 is an end view of the feed roller shaft introduced to show the movable bearing of the feed roller. Fig. 4 is a front view of the series of spaced blades for separating the fabric and steels after the action of the abrading device. Fig. 5 is a cross-section of the blades on the broken line w-a2 of Fig. i to show the edges of the blades all presented toward the same side. Fig. 6 is a cross-section of the end or termination of the bed next to the abrading belt, showing the yielding rubber edge portion over which the fabric and steels may bend as they pass the abrading contact. Fig. 7 is a top plan view of a yielding edge portion made of a number of blocks of rubber placed side-by-side, in

order that each may bend or yield independently of any other when one of the steels is stiffer than another. In this view is also shown the means for adjusting the yielding edge portion of the bed forward or backward. Fig. 8 is a side view of a modified construction of the yielding edge portion of the bed, comprising a spring rod or head that yields when pressure is applied that overcomes the force of the spring employed. In Figs. 3, 4, 5, 6, and 8 the scale of drawing has been increased.

Throughout the description and drawings the same numbers are used to refer to the same parts.

Considering the drawings, it will be observed that there are two side rails 1 and 1, and upon the rails near the left end are the bearings 2 and 3. These bearings are pivotal supports for twin vertical arms, such as the arm 4 shown in Fig. 1. At their upper extremities the vertical pivotal arms are provided with the bearings 5 and 6, and in those bearings are held the trunnions or journals of the upper drum 7. The drum 7 is one; of a pair of like drums, the fellow drum being the lower one and designated by the number 8, and held in the bearings 9 and 10 on the rails mentioned.

Connecting and encircling the drums is the abrading belt 11, the outer surface being supplied with any chosen abrading material or grinding devices. It is not the intention in this application to limit the invention to the use of the belt abrading device, as it is believed that other means of common knowledge could be used for the purpose. To hold the upper drum in its raised position as set out in Fig. 1, an inclined brace 12 is our ployed that has its upper end pivotally secured to the arm, and its lower end provided with teeth enabling it to engage the ratchet bar 13 on the rail 1. It will be understood that there is a second inclined arm on the other rail, as shown in Fig. 2, the same in construction and operation as the arm 12 de scribed. lVhenever it is necessary to apply tension to the belt 11 in order that it may be driven without slip, a bracket 1-1 is socured to the arm 4-, and a weight 15 hung from the outer end of the bracket. It is believed to be clear that, if desirable, the second vertical arm may be also equipped with a like bracket and weight.

As illustrated in Fig. 1, a motor 16 by means of a. chain 1? drives the main gear 18 and rotates the lower drum thus driving the abrading belt 11.

On the same shaft with 1 the gear 18 is a sprocket wheel 19, which by a chain 20 drives a sprocket 21 on the feed roller shaft. The feed roller 22 is thus driven, but at a slower rate than the belt 11. Any desired speed ratio may obviously be reached by suitably proportioning the sprockets. In Fig. 3 it will be noted that the bearing 23 for the reed roller shaft 24 is movable up and down, and inequalities of thickness in the material or article passed beneath the roller will not, therefore, stop the feeding.

The table or bed proper is referred to by the number 25, and, as illustrated in Fig. 6 the fabric or corset 25 and the steels or stiffeners 27 bend as they pass downwardly over the edge of the bed against the abrading belt. It is customary in practice to provide the bed with a yielding edge portion consisting of the rubber plate 28 extending along the edge. The yielding edge allows the steels to bend in passing and then to straighten out in a direction substantially tangential to the curve of the belt upon the lower drum.

As the fabric, with the upper layer of cloth ground off, and the exposed steels pass downwardly from the edge plate 28, the fabric encounters a series of blades presented edgewise and arranged vertically or slightly inclined, and spaced apart. The steels pass between the blades and are not materially diverted thereby from their normal path, but, the fabric is turned away from the abra'ding belt. The blades are designated by the number 29 and they are connected and supported by means of an edged backbone 29. After being turned aside by the blades the fabric passes between two extractor rolls 30 and 31, by which the fabric is drawn to one side of the partition 32 and deposited in a selected compartment, while the steels pass between the extractor rolls 33 and 34 and are deposited in another compartment.

Considering now, Fig. 7, it will be understood that the yielding edge portion of the bed or table 25 may be made up of a number of rubber blocks 35 arranged side-by-side and secured in place by means of the cover plate 36. The plate 36 has near its ends the

recesses

37 and 38, and by means of the

screws

39 and 40, the plate may be adjusted forward or backward in the recesses 41 and 42 in the rails.

Next considering Fig. 8, it will be understood that the edge of the bed may comprise a number of devices each having a head 43 and a shank or stem 44- encircled by a spring 45 seated in a suitable cavity 46. The shank or stem is movable back and forth in a bore 47 in the bed, and has a. ver tical slot 48 through which a screw or bolt 49 passes movably. It is believed to be clear that if pressure is exerted upon the head 43 by fabric drawn more or less tightly over it,

the head will yield backwardly when the force compresses the spring 45. Occasionally, it is most advantageous to have the edge of the bed formed of the independent, resilient sections described. Each section may then yield in correspondence with the thickness of that particular portion of the corset between it and the abrading belt, without affecting the yielding of the next sections. Where the thickness of the corset acted upon varies at different pointsor lines of its width the sectional edge is especially useful.

Again considering Fig. 2, there will be observed on the shaft 24 of the feed roller 22, a sprocket wheel 50 which is connected by a chain 51 with a sprocket wheel 52 upon the outer end of the extractor roller 34. The roll 34 is thus driven, and by means of the meshed gears 53 and 54 the roll 33 is also revolved. Also in Fig. 2 is shown a sprocket wheel 55 on the shaft of the feed roller, and a chain 56 thereon. By means of a sprocketwheel not shown, the chain 56 drives the extractor roll 31, and meshed gears similar to the gears 53 and 54 drive the fellow roll 30. The construction and operation'are alike in all respects to those described as relating to the extractor rolls 33 anc 34, and it is thought need no special explanation.

On the outer end of the feed roller shaft 24, as shown in Fig. 2, is a sprocket wheel 57 connected by a chain 58 with a sprocket wheel 59 that is in one piece or fixed upon a gear wheel 60. The sprocket 59 turns the gear 60, and the gear 60 rotates the gear 61 by whichis driven the angular gear 62 onthe diagonal shaft 63. One end portion of the shaft 63 is held in the angular bearing 64 and the other end of the shaft is rotatively supported in the upright block or bar 65 of triangular cross-section which is attached to the middle of the bridge 66 that spans the bed from rail to rail. A second shaft 67 extends also in a diagonal direction with respect to the bed 25, and at an angle with the shaft 63. The shaft 67 is journaled in the angular bearing 63 at its outer end, while its inner end is supported in the block or bar 65 already mentioned. Near the ends of the shafts 63 and 67 described as journaled in the block or upright 65, the shafts are provided with the miter gears 69 and 70, and the cylindrical spreading and feeding brushes 71 and 72 are thus driven. It is not the intention to limit this invention to the spreading and feeding brushes illustrated and explained, for the reason that other equally well known means could plainly be substituted to the same end. The revoluble brushes are convenient, adaptable and effectreated.

In the operation ofthis invention, be- 130' lieved to be now readily discernible from the drawings and the foregoing explanation, the corset or part thereof is fed upon the table 25 under the roller 22 and over the yielding edge of the table or bed against the abrading belt 11. The diagonal brushes 71 and 72 operate to spread the corset laterally as well as to aid its feed to the feed roller 22. The abrading belt grinds off the upper layer of cloth exposing the steels and permitting them to be removed. The series of blades 29 divert the fabric to the extractor rolls 30 and 31 by which it is drawn from the belt, while the steels straighten out and pass between the rolls 33 and 34 into another C0111 partment or receptacle.
