COLLAR-STRETCHING MACHINE.

Application led July 12,

Our present invention relates to improvements in collar stretching machines by means of which collars, cuits, collar bands, etc., may bestretched and shaped before iinal completion and attachment to a shirt. As is well known in the craft or trade, the collars, cuiis, collar bands, etc., after having been sewed about their outer edges and ready for completion, or Jfor attachment to a shirt, are in a more or less wrinkled condition, and therefore require pressing to eliminate these objectionable features. We find in actual practice by the use ot our machines involvingl the present invention, that the collars etc. may be stretched to eliminate the wrinkles and properly shaped' to provide accuracy and uniformity in sizes and styles, and at the same time impart to the collar or other article the necessary pressed appearance.

These desirable results are attained together with a saving in time, labor, and the number of machines employed, as compared with the present practice ot pressing the collars or other articles, thus materially reducing the cost of manufacture ot` these articles.

The invention contemplates the employment of a machine employing a pair of complementary, relatively movable templets or dies and their carriers, together' with suitableV control and operating means, whereby the templets of selected shape are adapted to stretch andproperly condition a collar or other article carried thereby. The pairs of templets are interchangeable ior use with the 'machine thus permitting the employment' ot templets complementary to collars, cuffs, and collar bands, and corresponding to the size and style ot the article to be stretched and shaped. y

- The invention consists in certain novel combinations and arrangements of parts for accomplishing` the above .indicated results as will hereinafter be more fully pointed out and claimed. Y

In the accompanying drawings we have illustrated one complete example ot the physical embodiment of oui-invention, together with several templets, wherein the "0 parts are combined and arranged according to one mode that has proven highly successtul in actual use, but it will be understood that changes and alterations may be made in the application of the principles ot our invention, within the scope of our claims,

Figure 8 is an enlarged plan view of an interchangeable cuff-die or templet, and Figure 9 is a similar view ot an interchangeable collar-band die or templet for use with the machine.

The machine is designed tor use in stretching and shaping both detachable, and attached, collars andy cutis, as well as tor use Y with collar-bands and other articles, but Yfor convenience of illust-ration and description we have shown and will hereinafter refer to the machine in connection with the per- 9 0 ot collars. .In Figure 5 a collar is indicated at C with an open, incomplete seam at its inner edge, and shown supported in proper shape and position on the pair ot complementary left and right teniplets l and 2. '95 These templets are preferably made of brass and fashioned in this instance to conform to the shape and size Vot a fold-collar that mayV either be attached to a shirt. or when completed `be worn as a detachable collar.y Y

The templets are used in interchangeable, complementary pairs, each die or t-empletl ot a pair being horizontally disposed for use and fashioned as a flat .plate with an end notch 3 and angular inclined edge hand 105 au inwardly curved edge, ,which parts are adapted to receive and retain the Vcollar C as indicated in Figure 5.

In the process of stretching and shaping the collar these templets are relatively moved, outwardly, from position of Figure 4 to that of Figure 5. Each machine is equipped witha set or suitable number of interchangeable templets, the templets of the selected pair being detachably secured, as by screws or bolts 6 at the upper ends of a pair of upright carrier- plates 7 and 8 fashioned from suitable material, preferably brass. Each carrier plate is formed with a top, horizontal flange 9 to which the dies are secured by the screws or bolts 6, and the plates extend downwardly through a pair of slots 10 and 11 in the wood tabletop 12. A pair of metal guide plates 13, which are slotted to conform to the slots of the table top and attached to the upper face of the table top, are used to guide the carrier plates and retain them in proper position at all times.

The table top, which is located at a convenient elevation from the floor for ready access by the operator of the machine, is supported upon a frame or stand 11i here shown as made up of pipe sections and including corner legs or posts, horizontal braces, base plates and attaching plates for the table top. The spaced slots of the table top and the complementary slotted guide plates for the carrier plates, extend along the longitudinal center of the table top, and the carrier plates which are supported from beneath the table top are designed for relative movement along the longitudinal center of the machine.

For this purpose the lower ends of the carrier plates are fashioned as carriages and each provided with a pair of spaced, grooved rollers 15, journaled in the plates at 16 and alined to travel in contact with and between the upper and lower, horizontal guide rails 17 and 18. These guide rails are provided with brace bars and form a frame attached to the underside of the table top, and the bars are of the required length to permit the necessary outward and inward travel of the carriers for the templets. By means of a spring 19 attached at its ends to the complementary flanges 20 of the two carriers, the latter are normally pulled inwardly toward the longitudinal center of the machine, and a double-end bumper or shock absorber 21 is secured to the rail-frame at the center of the table in the path of movement of the carriers to receive impact from adjoining rollers on the two carriers, cushion the movement, and act as abutments for the carriers when the templets are in contracted position.

or other suitable flexible connections, are attached, as at 26 to the opposite sides of the pedal, and extend upwardly toward the center of the table top, and over a pair of groored guide pulleys 27 and 28 journaled in bearing brackets 29 fastened at the underside of the table top. From the center of the machine the chains extend outwardly and pass over guide pulleys 8O and 3l which are journaled in suitable bearing brackets as 32 fastened to the underside of the table top near its ends. From these guide pulleys the respective chains extend inwardly and have at their ends attaching rings 33, hooks, or other suitable means for fastening to the perforated ears or lugs 3/1 fashioned at the outer ends of the two carriers. The spring is of sufficient tension to exert the necessary pull on the carriers for pulling them in toward the center of the machine, holding the chains taut, and elevating the pedal to its normal position as'shown in Figures 1 and After the collar has been slipped over the adjacent templets 1 and 2 and properly adjusted thereon, by depressing the pedal 22, the two carriers and their templets, through the instrumentality of the draw chains, are gradually separated or moved outwardly in opposite directions from the center of the table, to extend, stretch and properly shape the collar to conform to the shape of the templets, the collar being adjusted and fitted to the templets by the operator as the stretching proceeds. The desired movement of the templets is governed by the operator who quickly becomes skillful in manipulating and adjusting the collar and operating the pedal to insure the proper set, shape and finish of the collar.

After the desired treatment of the collar, the pressure on the pedal 22 is released, the spring automatically draws the carriers to the normal position against the shock absorber or abutment 21, and the operator simultaneously slips the Collar off of the templets, replacing the first collar with a second one, and continuing the operation of stretching and shaping the collar. yFor different styles or shapes of collars, different templets may be used, and these are readily interchanged by removing the screws or bolts 6, adjusting the desired or selected templets on their carriers, and replacing the screws.

For stretching and shaping a cuff, a pair yof templets, of which one templet is designated 35 in Figure 8, is used, and attached .by the screws 6 to the attaching flanges 9 of the carrier plates.

In Figure 9 a collar-band templet 36 is shown attached by screws 6 to the attaching flange 9 of the carrier plate.

The various pairs of templets are thus interchangeable and may with facility be changed as desired to enlarge the scope of the work performed on the machine, and

enable the operator to produce various kinds of work on the same machine.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is l. In a machine as described the combination with a pair of relatively movable carriers, means for extending` said carriers, and automatic means for returning said carriers to normal position, of a pair of detachable, complementary templets, whereby an article may be stretched and shaped, as set forth.

2. The combination with a. slotted table top and slotted guide plates, and spaced rails supported belen1 said top, ot' a pair of relatively movable carriers supported on said rails and resilient means connecting said carriers, templets secured to said carriers, and means for extending said carriers in opposite directions.

3. In a machine as described, the combination with a support-ing table having a car rier frame and a pair of relatively movable carriers on said frame, of resilient means connecting said carriers, means for impart-- ing a separating movement to the carriers against the resistance of the resilient connecting means, and a pair of complementary ternplets attached to said carriers.

t. In a machine as described, the combination With a slotted table, a carrier frame attached at the underside of the table, and a pair oi alined, Wheeled carriers Ion said frame, of a spring connecting the carriers, a. pedal, means connected to each of the carriers and to the pedal for separating said carriers against the tension of the spring,

and a pair or' complementary templets carried by said carriers.

5. In a machine as described, the combination with a table top having spaced slots Vand alined, slotted guide plates, a supporting frame including a rail rigid With and located beneath the table top, and a pair of Wheeled carriers on said rail, of a spring connecting the carriers, a. pedal, a chain attached to each of said carriers and to the pedal, guide pulleys for the chains, and a pair otl complementary, detachable templets attached to the carriers above the table top.

In testimony whereof We have aHiXed our signatures.
