20 Claims.

This invention relates to a garment press of a new type, which I name the turret press.

The invention further relates to presses that press a shirt, waiters coat and such like garments in one operation as to the body of the garment with the sleeves, collar and cuffs being otherwise ironed.

I am aware that it has been proposed to construct a machine with vertical pressing jaws, one of which is relatively fixed with the other movable towards and from the first named jaw and to pass bucks, roughly shaped like a human bust between them to form press a garment thereon, ironing'both the front and rear at the same time.

In pressing garments of the kind, the first problem is varying sizes, say from size 14 to 18. Two bucks of different sizes do not lend themselves to proper draping and ironing of all sizes; three is much better but still somewhat inadequate. A further problem is that one pair of press jaws must be a compromise and being adapted to work on several sizes of bucks cannot closely fit any ofthem, hence does not perform the highest class of work. -5 The object of the present invention is first, adequate production with a relatively long period when the press jaws are actually ironing a garment inplace on a buck that fits the jawsin each case, hence doing the very best quality of work.

Another object is a machine that is adapted to first quality work, with a comparatively low steam pressure for heating the press jaws, hence wide adaptability as few laundries have high pressure, high heat boilers.

described, the production rate of which is limited, not by the time limit necessary to dry and iron a shirt with one pair of press jaws, but only by the skill and dexteritycf the operators, attained by reason of having at least two heated pairs of press jaws in active pressing service at all times when the press is in service. Longer contact time permits effective ironing with lower pressure temperature steam than with a single pair of jaws.

A further object is a multiple pressing machine assembly that is capable of utilizing the production line principle that has made modern automobile and other production methods so effective, that of moving the work to the operator at predetermined speed instead of depending upon the individual operative to set the pace.

Other and more specific objectswill be. apparent-to those skilled in the artto which this in- A further object is a machine of the class vention appertains as the specification and the drawings hereinafter described-are considered.

The drawings are of a preferred type of a machine according to the present inventionbut are shown by way of explanation and not intended as 6 a limitation since I do not choose-to be limited save by the claims hereto attached. I believe that I am entitled toclaim this type of machine broadly, hence the drawings will be taken as illustrative only and the nature of the invention and scope thereof are to beascertained from the claims.

Fig. XII is a section taken at.XIIXII, Fig. II.

In the drawings, l is a. base upon which a turret 2 is revolubly mounted. In operation the turret will be kept revolving at such speed as may be desirable to allow two operatives to drape and undrape the bucks as the several pressing machines carried by the turret press the garments and open successively for that purpose.

Mounted on the turret 2 and revoluble therewith are four identical pressing machines, save that preferably the bucks and cooperative pressing jaws for'each buckwill be arranged for vary -ing sizes of garments.

These pressing machines are shown in Fig. I at top, bottom, right: and left positions on, the drawings, though two. of them are broken away somewhat to accommodate. the drawing to the 65 sheet.

dicia.

Each pressing machine comprises a pair of cooperative pressing jaws J, which are concaved to fit a buck B and substantially enclose it with its own motor devices to open and close the jaws. This construction is shown in the sectional views, Figs. VI to XI inclusive, and it will be understood that the shapes there shown are diagrammatic and may be varied quite widely so long as the buck is roughly in the form of a human body, provided with a neck portion, and without any provision for sleeves. Sleeve supports will be provided but they are old and deemed unnecessary to delineate in these drawings.

It is thought that clarity of this specification can be improved by describing one pressing machine in detail, it being understood that save for variations in size of the external outlines of the several bucks and the corresponding concavity of the cooperative pressing jaws, the same description may be applied to each and every one of the other pressing machines. With the exceptions stated. the same patterns and finished dimensions will be used to build them.

The bucks B will be made of any suitable material, which may be laminated wood, spruce, or any other wood that is not pitchy can be used; or the bucks may be hollow castings or formed in sections of strong sheet metal and autogenously welded together. The bucks will be covered with a jacket of resilient rubber about one-half inch thick, outside of which will be the close woven cotton cover according to the known art.

As shown in plan in Fig. I, hinge lugs 4 are equally spaced around the turret 2. These hinge lugs are provided with bores within which the pins 9 are mounted to hingedly engage swinging press supporting arms of the kind shown detached from the machine in Fig. IV.

In the drawings there are four pairs of these swinging press arms, which being identical except that they are rights and lefts, are given the reference numerals 6 and I for right and left respectively.

The lower hinge lugs that cooperate with these swinging arms are for the most part hidden by other apparatus, but it will be understood that they are in precise alignment with the upper ones and will be given the same number with the subscript a.

Though the swinging press arm indicated by the numeral 1 in Fig. IV will be of composite construction, it will be regarded as a single unit and has cooperating hinge parts la and lb, a distance piece 1c and pivoted mountings 1d and 1e wherein are mounted the pivots Illa and lflb of the press jaw J.

These swinging arms, especially the top and bottom parts thereof, are preferably made of steel castings and have cams made rigid therewith, which cams are indicated by l2 and I3 (see Fig. I).

A yoke I5 is provided with a pair of cam rollers It so spaced that they span the distance between the cams l2 and I3 and roll in them. This yoke is reciprocable under the influence of the double acting expansion motor l! which contains a piston l8 and a piston rod l9, which is connected to the yoke l5, as shown in Fig. I.

An identical arrangement is reversely placed on the under side of the swinging arm, and the two motors being identical are given the same number, IT, and the lower motor assembly is They are not given distinguishing incontrolled to reciprocate in unison with the upper motor assembly.

It will be noted that the cams l2 and I3 are two stage, having a relatively great angle in the portion marked 12a and a relatively small one in the portion marked I21), and all other cams are made the same way except that they are right or left as delineated.

It will be observed that while the cam rollers 16 are traversing that portion of the cam marked l2a, a rapid opening or closing movement results and while they are traversing the other portion which has a relatively small angle, as shown in the other views where the pressing jaws are together, a very high pressure will result tending to close the press jaws firmly over the bucks.

The press jaws are steam heated, having steam spaces marked 20, Fig. IX, which are connected to the metal hoses 2| by what is known as the single pipe heating system, that is the steam goes in and the condensate out ofthe same pipe; hence drainage must be arranged for. The hose is connected to the swivel 22 Within which the turret 2 is supplied with steam by the steam pipe 23 and a condensate trap not shown will be attached to the steam pipe 23 at a convenient point to dispose of the condensate.

Rigidly attached to the turret 2 is a buck supporting arm 25, there being one for each pressing machine.

A buck carriage 26 is slidably mounted on the arm 25 and a buck B mounted thereon is reciprocable into and out of pressing position between the jaws under the influence of the double acting expansible type motor 21.

The buck carriage 26 has a very important auxiliary, that is the offset pivotal mounting or pin 28 which is pivoted at 29 to the carriage and at 30 to the buck B.

This mounting permits a rocking motion of the buck B or a yielding of the buck B in either direction. If perchance the pressure of the jaws be not applied to the buck absolutely simultaneously, then the ofiset mounting will yield or the buck will turn slightly on the pivot 30 so that no damage is done.

A compressed air supply pipe 40 is axially disposed with respect to the turret 2 and connected to a supply of compressed air remotely situated and not shown. It is supplied with a swivel 4| from which pipes 42 lead to control valves such as 43. These valves such as 43 are operated by push rods 45 and the push rods 45 are controlled by a cam 45a. The followers 46 on the end of the push rods 45, are constrained to follow the surface of the cam by influence of the springs such as 41.

A cam 50 simultaneously controls a valve 5| by moving a pushrod 52 according to its contour. The pushrod 52 is constrained to follow the cam by the spring 53 and appropriately furnish compressed air to one end of the motor served and exhaust the other end. The same thing happens with respect to the motors I! which are supplied concurrently with air at the same end and ex-' hausted at the other end. There is a full complement as above for each machine, all governed by the same cams.

It will be noted that all of the air motors are double acting and that when the pressing machine is in service there is no neutral position. One end or the other of each motor is always under air pressure. To prevent slamming, the exhaust openings will in all cases be provided with a throttling cock or similar regulating means, hence the exhaustedend of ajmotor serves asa cushion for the active one. This is an old and well known expedient hence it has not been deemed necessary to further complicate the drawingsby showing it.

Turning now to Fig. XII, the broken line A represents the point where a pair of press jaws open and'immediately following that, motors such as 21 will be energized from the end next the turret 2 and'the buck B will beejected from between the jaws J to the position shown at the lefthand end of the sheet in Figs. I and II.

Returning to Fig. XII, the broken line B represents the. place where first the motor such as 21 will be actuated in an opposite direction, pulling the buck B'into pressing relationship with the jaw J, immediately following which the pair of motors such as I! will be energized from their inside ends with the other end placed in exhaust.

It is intended that an operator shall be present to undrape a buck of its pressed garment immediately it opens and the buck is ejected at point A and that another operative will be present and drape a damp garment on the buck just undraped in time for it to be drawn into position for pressing when the pressing machine reaches the point B. The turret carrying the pressing machines will revolve at one revolution in four minutes, more or less.

It will be immediately apparent that by shifting the earns and 50, the machine is in effect turned around; hence there is no such thing front or rear and it may be made'to open and close at any point on the given zone of operation represented by the curved lines with arrow points in Fig. XII. By changing the lengths of the cams 45a and almost any variation in operating sequence may be obtained.

The bottom of the turret 2 is supplied with a rigidly attached bevel gear 60, meshing with the bevel pinion El and a broken shaft 62 receives power of appropriate amount and at a speed suitable to the operation as described. This delineation is diagrammatic.

It will be understood that while I have described only one pressing machine that the same description as mentioned before serves for all of them because they are identical in every part save for the curved outline of the bucks and the contra curved inside surfaces of the press jaws J.

A great many details appearing in the drawings have not been given reference numerals or described, but their purpose is obvious and the drawings are somewhat diagrammatic especially as to the pipe work that supplies the different motors with compressed air. This pipe work has of necessity been brought out into sight where it can be referred. to, but actually it is copper tubing that lies in most cases close to the turret or other relatively fixed parts and is prop- 1.
