Specification of Letters Patent.

raten-teu Apr. 22, i913.

To all whom t may concern:

Be it known that we, JOHN SCHREINER and FRED KURZ, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Seam-Da1npeners, of which the following is a specication.

This invention relates to machines such as are employed in laundries for the purpose of dampening the seams of turn-over collars, after the collars have been ironed fiat, to permit the collars to be turned over or folded along the seams.

The object of the invention is to pro-vide machines of the kind in question with improvedv means for guiding the collars while they are under the influence of the feedingmeans, and particularly to render such guiding-means adjustable to adapt them for use with collars of various sizes and styles. To this end we employ, as one feature of the invention, a presser-roller which engages the collar in advance of the feeding and dampening means, this roller being adjustable in various directions and particularly in a manner to vary the angle of its axis of rotation to the line of feed so as to accommodate the machine to collars of dierent curvature. We also employ a device in the nature of a kick-01T, which frictionally engages t-he collar, and which is also adjustable in various -ways to modify its action upon the collar, and in connection with the presserroller and the kick-01T we employ a unitary device for supporting both of these members, together with connections permitting them to be adjusted independently of each other.

The invention will be more particularly described in connection `with the embodiment thereof illustrated in the accompanying drawings, in which- Figures 1, 2 and 3 are, respectively, a front-elevation, a plan-view andan endelevation of a portion of a seam-dampener embodying the present invention; Fig.` 4 is a vertical sectional view on the line 4 4 in Fig. 2; Fig. 5 is a diagrammatic planview, on a larger scale than the other iigures, illustrating the manner in which the guiding-devices coperate with a collar; Fig. 6 is a detail view of the kick-oii shown in vertical section on the line 6 6 in Fig. 4, looking from left to right in the latter ligure.

As the invention resides particularly in novel guiding or work-controlling devices which are applicable to seam-dampeners of various forms, the particular construction and arrangement of t-he feeding and dampening means in conjunction with which they are employed are illustrated only in so far as is necessary for an understanding of the invention, the invention being shown as embodied in a machine of the type disclosed in United States Letters Patent to Mattice, No. 851,541, dated April 23, 1907. The drawings illustrate the upper and lower feedingand dampening- rollers 10 and 11, respectively, mounted upon, and actuated by, shafts 12 and 13 which are journaled in a frame 14, the lower roller 11 dipping into water in a tank 15, all as in said patent, The machine is also shown as provided with the usual seam-guide, comprising members 16 and 17 operating through an opening in the table of the machine, the seam being guided in a channel 18 between these members. The scam-guide is carried by arms 19 which are pressed upwardly by a spring 20, and it is adjustable transversely by means of a thumb-screw 21.

In the machine of the Mattice patent the seam-guide constitutes a lower, yielding work-support, while the collar is held down, against the pressure of the seam-guide, by means of a presser in the form of an arm having a smooth stationary face which engages the upper surface of the collar directly above Vthe seam-guide. In accordance with the present invention, however, we employ, in place of this stationary presser, a roller 22 which is journaled in a fork 23. By' means of a screw 24 this fork is clamped against one arm of a bracket 25, and the other arm of the bracket is clamped, by means of a screw 26, to a block 27. The screw 26 passes through a slot 28 in the block to permit an adjustment which will be referred to hereinafter. The block 27 is in turn support-ed by a stationary arm 29 proj ecting forwardly from the frame 14 of the machine. This arm is provided with a slot 30 through which passes a screw 31 threaded into the block, and this form of connection permits both angular and transverse adjustments of the block for a purpose which will be presently described.

The construction and arrangement of the means just described for supporting the roller 22 permit universal adjustment of the roller. Upon loosening the screw 26 the bracket 25, together with the fork 23 and the roller, may be moved forwardly or rearwardly, thus varying the distance of the presser-roller from the feed-rollers in the direction of feed'. By the same connection the height of :the roller may be adjusted, thus regulating the cooperative relation between the seam-guide and the roller. By loosening the screw 24 the fork 28 may be rocked about the screw, thus providing an adjustment by which the roller `may be caused to have an even bearing upon the work, or by which compensation may be made for differences in the thickness of the two parts or fo-lds of the collar which engage the respective members 16 and 17 of the seam-guide.

Upon loosening the screw 31 the block 27 may be moved transversely, owing to the employment of the slot 30, thus adjusting the presser-roller transversely with respect to the line of feed, and, by swinging the block 27 around the screw 31, the angle of theaxis of-rotation of the presser-roller to the line of feed may be adjusted.

The adjustment last referred to is of importance as it enables the presser-roller to assist the seam-guide in properly directing the work through the machine, particularly by reason of the fact that there is more or less longitudinal vcurvature in a collar when it is ironed flat. As shown particularly in Fig. 5, it will be apparent that, by adjusting the presser-roller to the angular position shown, this roller, in addition to holding the collar down against the seam-guide, may be caused to have a tendency to swing the collar in the direction of its curvature, thus causing it to' move through the curved path necessary to enable the feedingand dampening-rollers to follow the line of the seam. In different styles of collars this longitudinal curvature varies greatly, but by 'changing the inclination of the presser-roller the machine may be adapted to operate upon all the various styles and sizes of collars commonly employed, feeding them with certainty and precision.

The arrangements for adjust-ing the presser-roller horizontally, both transversely and in the direction of feed, have utility particularly in connection with the means employed to prevent the machine from dampening the tab at the end of the collar. The machine is illustrated as provided with a device 32 which is familiar on such mais commonly designa-ted as a kick-off.

This device rests frictionally upon the upper surface of the collar and is mounted upon an arm 33 journaled upon a fixed shaft 34. The arm 33 and the kick-off arepressed downwardly by means of an adjustable spring 35 by which the pressure of the kick-off upon the collar may be regulated.

It will be apparent that as the kick-off 32 is located entirely upon the right--hand or inner side of the feeding and dampeningrollers it subjects thecollar to a friction or drag which tends to swing the collar to the right as it passes through the machine. This tendency isto some degree counterbalanced, however, solas to preventactual deflection of the work, by the presser and the seam-guide, which subject the collar to a frictional drag on the opposite side of the feedingand dampening-rollers. lVhen the end of the collar is reached, as shown in Fig. 5, `the outer fold 45 of the collar moves out of engagement with the kick-off 32, and, in order that the drag may be removed from the otherpart of the collar at' approximatelyy the Sametime, the presser-roller should be arranged at such a distance from the feedrollers that its engagement with the tab 46 of the collar may terminate as thelfold-45 leaves the kick-off 32. This arrangement is facilitated, in the-present invention, by the provision for adjusting the presser-roller toward and from the feed-rollers,'this adjustment permitting -the machine vto be adapted for use with collars of different styles having tabs of differentlengths. In the same connection the provision for transverse adjustment of the presser-roller is important, since thispermits the presser-roller to be adjusted in suoli position as properly to engage the tab whatever the form of the latter may be, some tabs being Varranged at a greater angle than others with the line of the seam 44.

It is highly desirable to prevent engagement of the feedingand dampening-rollers with the tab of the collar, in order thatA the latter may not be marked or defaced by the dampening action, and the kick-off 32 commonly employed in machines of this type is intended to accomplish this result. We have found, however, that it will not do so with certainty, andwe, therefore, employ anad- `ditional kick-o or frictional device which spring43, fixed at one end to the block 27, engages, at its other end, any one of a series of notches on the inner side of the stem 37, as shown particularly in Fig. 6, and this spring serves to press the kick-off 36 against the surface of the collar.

The construction just described provides for supporting the kick-off 36 upon the block 27 in common with the presser-roller, so that the kick-off and the presser-roller may be applied to the machine as a4 unitary attachment, but the connections, including the arms 39 and 41, provide for universal horizontal adjustment of the kick-o 36 independently of the presser-roller. Accordingly, the kick-off may be adjusted toward or from, or transversely with respect to, the n feedingand dampening-rollers, and it may also be adjusted angularly about its vertical axis.

In F ig. 5 the kick-off 36 is shown in such a position that it engages the outer fold of the collar, thus subjecting it to a certain amount of frictional drag which tends to assist the other parts of the machine in directing the collar properly. The effect of this drag may be adjusted in two ways. In the first place, t-he pressure of the kick-0H against the work may be adjusted by engaging the spring 4:3 with one or another of the notches in the shank 37. In the second place, the point of application of the friction may be adjusted transversely with respect to the feeding- `and dampeningrollers. With respect to this latter adjustment, however, the kick-off is preferably so located as to just clear the inner edge of the tab when the collar reaches the position of Fig. 5. Accordingly, when the outer fold 4:5 of the collar moves beyond the kick-off 36 the latter is depressed, by the spring 43, into engagement with the table of the machine. The kick-off 36 then acts as a positive stop or guide which may be engaged by the edge of the tab, and which will positively prevent the tab from passing between the dampening-rollers. In connection with this last function the angular position of the kick-olf 36 may be adjusted to correspond to the angle at which the tab projects from the body o-f the collar, thus causing the edge of the tab to be engaged evenly by the fiat lateral surface of the kick-off.

By the conjoint use of the presser-roller and the kick-off above described the seamdampener may be adapted to operate with certainty upon collars of a great variety of shapes and sizes. It will be understood, however, that while the invention, in its most complete embodiment, contemplates the conjoint use of these two devices, it is not limited to such use, and that the invention, in general, is not limited to the embodiment thereof hereinbefore described and illustrated in the accompanying drawings, but

may be embodied in various other forms within the nat-ure of the invention as it is defined in the succeeding claims.
