PRES S ING MACHINE Filed June 14, 1937 Patented Got. 11, 1938 UNITED-STATES PATENT, oF-FicE 4 Claims.

My invention relates to pressing machines, and more particularly to those designed for the pressing of collars and cuffs of shirts and the like, and my main object is to provide an improved press which will double the output of the work.

A further object of the invention is to provide a novel arrangement for the head and buck of the conventional pressing machine, whereby'to permit the collars and cuffsof two shirts to be ironed at one time. 1

Another object of the invention is to utilize the basic structure and mechanism of the conventional pressing machine in the adaptation of the novel head and buck arrangement, whereby to require no changes in the fundamental structure of the press. An additional object of the invention is to construct the novel head and buck arrangement along lines of extreme simplicity and without requiring any material changes in the balance of the press.

With the above objects in view, and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing in which- The figure is a perspective view of the head and buck constructed in accordance with my invention.

In the operation of the conventional collar and-cuff press, the attendant can only apply the work from the front, one shirt at a time. Thus, with the shirt held in upright position between the attendant and the press, the collar is laid over the collar bucks 5 of the buck frame 6 specifically indicated in the drawing, while the cuffs are laid over the cuff bucks lb opposite the ends of the collar bucks. The head 8 equipped with the corresponding bucks 5c and 1c is now caused to descend upon the work and press ,the same. Ordinarily, approximately five seconds are required for the attendant to adjust the collar and cuffs upon the bucks; and thirty-five seconds are usually required for the ironing opera tion and before the work can be removed for the introduction of the next shirt. The conventional forms of the prior art differ from mine in that the axis of curvature of the several bucks are at right angles to the transverse axis of my bucks. It has therefore been my intention to change the structure of the ironing bucks whereby to accommodate two shirts at one time and thus speed up the work.

In accordance with the foregoing, reference to the same manner.

the drawing shows the head 8 and buck frame 6. It is noted that the bucks of the conventional machine have been swung in a horizontal plane through a quarter turn, to appear as at 5b and 1b so that the lengths or curvatures extend from the front to the rear, instead of from side to side. Similarly, the head 8 has been developed with the bucks 5a and la in directions to correspond with the bucks 5b and lb, so as to appear as at 50 and 10. Also, the bucks 5b and lb, as well as their counterparts 5c and 'le are considerably Wider as seen from the irontthan in theconventional instance.

With a head and buck arrangement constituted as just described, it is seen that the attendant may apply one shirt from the right, and another shirt from the left. Thus, dotted lines indicate the upper portion of the first-mentioned shirt at I0, the cuffs thereof laid side by side on the bucks lb as indicated at II, and the collar laid H over the right hand portion of the buck 5b as indicated at l2. The corresponding parts of the shirt at the left are applied to the buck in Then the application of the head 8 procures the pressing of both shirts at one time.

I have calculated the average time of the attendant to apply the cuffs and collars of the two shirts to be eight seconds and often less, while the pressing time for both shirts is no longer when treated simultaneously than the time previously mentioned for a single shirt, namely thirty-five seconds. My method therefore procures a marked reduction in the time necessary for the ironing of the collar-and-cuff sets in 35 shirts. However, the efficiency of the method is more strikingly represented by the fact that two shirts are delivered from the machine in almost the time that it previously took to deliver one. This circumstance is of great value for the work dealing with the balance of the shirt. Since the material of the collar and cuffs is usually of double-ply, the ironing time is necessarily long to assure thorough drying. However, the other parts of the shirt are of the single-ply or relatively thinner material, so that the ironing time for such parts is much less. Therefore, it will be appreciated that the demand for shirts is more frequent where such other parts are being treated and is therefore supplied two shirts at one time by means of the improved press instead of a single shirt at a time, as in the conventional press. Therefore, the progress of the shirt through the ironing operations is so accelerated that it may be safely assumed that the speed of pressing shirts by machine will be doubled on account of my improvement.

Despite its advantages as just related, it is apparent that the bucks required by my improvement are quite as simple as before and need only minor variations in the construction of the head and buck frame in order to adapt these units to them. The balance of the machine is not changed in the least, and all the functions and mechanisms ofthe press are utilized as before. Thus, no special expenseis required to redesign or remodel the existing presses, nor is the attendant or operator required to learn different methods of control. The operator need only be shown how to apply the collar-and-cuff sets of the two shirts, and should become proficient after a little practice.

It will be evident from the above description that I have developed an improvement for existing pressing machines which, although exceedingly simple, attains an important if not radical advance in efficiency. At the same time, the new arrangement is compact, safe and handy to approach and use.

While I have described the invention along specific lines, various minor changes or modifications thereof may be made without departing from its principle, and I consider all such changes and refinements as coming within the scope and spirit of the appended claims.

I claim:

1. A pressing machine for simultaneously pressing the collars and cuffs of two shirts, comprising a frame mounting a substantially semi-cylindrical convex medial buck and a pair of substantially semi-cylindrical convex side bucks, one of said bucks being on each side of said medial buck in spaced relation thereto, the axis of curvature of all of said bucks being transverse of said machine, said medial buck being adapted to receive in laterally spaced relation the collars of two shirts, and each of said side bucks being adapted to receive both cufis of the shirt belonging to the adjacent collar on the medial buck.

2. The structure of claim 1, a head for said machine, said head carrying a set of concave forms complementary to said bucks.

3. A pressing machine for simultaneously pressing the collars and cufis of two shirts, comprising a frame mounting a substantially semicylindrical convex medial buck and a pair of side bucks, one of said side bucks being on each side of said medial buck in spaced relation thereto, the axis of curvature of said medial buck being transverse of said machine, said medial buck being adapted to receive in laterally spaced relation the collars of two shirts, and each of said side bucks being adapted to receive both cuffs of the shirt belonging to the adjacent collar on said medial buck.

4. The structure of claim 3, a head for said machine, said head carrying a set of forms complementary to said bucks.
