' PREssmc mesma Filed July 25, 1949 2 Sheets-Sheet 2 mwl Nw INVENTOR /zz//m/ Keer/42 ATTORN EY United States Patent Oiice 2,807,894 Patented Oct. l, 1957 PRESSING MACHINE Application July 25, 1949, Serial No. 106,565 Claims. (Cl. 38-10) This invention relates to the method of and a machine for smoothing, pressing, ironing, and compressing folded garments, to give them a more appealing appearance and to facilitate packaging.

Heretofore pressing operations were effected by the use of small presses which required a press operator and a folding operator for Veach press. The garments were folded and placed on a roller that carried the garments over the ironing surface of an electrically heated shoe arranged in vertical position and let the garments drop out vertically at the lower end of the press.

One of the main objects of this invention is the provision of a method of pressing folded garments which consists in arranging garments folded by a number of operators, atwise in a horizontal plane, in transporting said garments horizontally ilatwise into a pressing region, in pressing said garments and in delivering the pressed garments horizontally fiatwise in front of packaging operators in a packing region.

Another main object of this invention is the provision of a machine which will automatically transport garments folded by a number of folding operators, flatwise horizontally through a single automatically operating pressing mechanism and deliver the pressed garments horizontally flatwise in front of a number of packaging operators to be placed in envelopes, to be cellophane wrapped and/or otherwise packed in small containers.

It is a more specific object of this invention to employ a continuously moving horizontal carrier belt providing a long receiving apron or table on one side of a pressing mechanism and a long delivery apron or table on the other side of the pressing mechanism and preferably providing transversely a plurality of zones in which folded garments may be placed, whereby a slow moving carrier belt may be employed to transport the garments folded by a number of folding operators on each side of the machine through the pressing mechanism. i

Another object of this invention is the provision of improved means for supporting a presser shoe over a carrierbelt' including readily adjustable means for raising and lowering the presser shoe to accommodate folded garments of different thicknesses such as light and heavy weight goods and for setting the shoe at an angle with respect to the horizontal to apply increasing pressure on the folded garments in the course of their travel under the shoe, and the provision ofmeans for yieldingly opposing the upward movement of the shoe under the action of the folded garments tocontrol the pressure of the shoe on the folded, garments and thereby the compactness of the pressed folded garments. f

Numerous other objects and advantages will become apparent from the following descriptionof the invention made with reference to the accompanying `drawings in which; i

p Fig. l shows more or less diagrammatically in plan the general layout of the machine and associated operators tables; Y v v 1 Cil Fig. 2 is a side elevational view of the machine shown in Fig. 1;

Fig.l 3 is a vertical cross section through the carrier belt and table at the rear lof the presser shoe taken on the line 3-3 on Figs. 2 and 4; and

Fig. 4 shows the presser shoe in its relation to the table and carrier belt when viewed as indicated by the arrows 4-4 in Fig. l.

The drawings illustrate a preferred mechanism for practising the method according to this invention.

The machine includes, Figures l and 2, a long and relatively wide main table generally indicated at MT provided with a smooth table top on which -is supported the upper horizontal course of a carrier belt B that passes over rollers 5 and 6 mounted at the ends of the table top and rollers 7 suitably journalled below the table top as shown to support the lower course of the belt. The roller 6 may be journaled in a guard bracket 8 as shown.

The roller 5 is driven counter-clockwise, Figs. 1 and 2, at any desired suitable speed by any well known motor reduction gear mechanism such as indicated broadly at 10 to give the upper course of the carrier belt B a continuous movement at any desired speed toward the left as indicated by the arrow thereon, tocarry folded garments under and past a presser shoe S, the construction of whichwill be described later. A smooth faced plate 11 is preferably alxed in the top of the table directly under the presser shoe S.

The right hand section of the upper course of the carrier belt, Figs. land 2, constitutes a receiving apron or table upon which the folded garments are placed. The carrier kbelt is preferably made wide enough so that folded garments may be arranged thereon in a plurality of rows for the convenience to folding operators on opposite sides of the table and for increasing the capacity of the machine. It is made long enough to accommodate a'plurality of folding operators on each side of the machine and preferably a folding table 12 is provided for each folding operator. These folding tables may be arranged in staggered relation to save space and for the convenience of right and left handed operators.

Each folding table 12 may be rectangular as shown providing an area for receiving a pileor stack 14 lof unfolded garments and a working area on which the garments may be folded as indicated by a folded garment at 16. The 'inner end of each folding table 12 may be suitably supported on the edge of the main table by any suitable hinge construction 17 and its outer end by legs 18 which may be hinged thereto (not shown) and resting preferably on a base rail 20 as indicated. The folding tables 12 may be separably mounted on or integrally connected to the main table as desired. It is preferable to mount these tables with their upper surfaces substantially in the plane of the carrier belt so that the folded garments may be removed from the folding tables and placed on the carrier belt by a horizontal movement to prevent any disturbance of the folded condition ofthe garments.

As shown in Figs. l and 3, the wide carrier belt B may be divided by demarcations, such'as threads 21 in a Woven belt, into a plurality of zones, and if desired folded garments may be placed and arranged in these zones to approach the presser shoe in the order shown in Fig. l so that the folded garments are carried in succession under the pressershoe successively in different transverse zones, thus facilitating uniform heating of the presser shoe and uniform pressing, ironing and compressing of the folded garments.

The folded garments so arranged or placed on the carrier belt or in any otherdesired or casual arrangement are carried Without being disturbed under and past the presser shoe into a packaging and packing region at 3 the left Vhand end of the machine, Figs. l and 2, where they are removed by packaging operators stationed on each side of the main table for the convenience of which long narrow working or boxing, tables 23 may be provided formed on or secured to the main table in any suitable manner. It is desirable for the convenience of the packaging operators to arrange the top surfaces of these tables substantially in the plane of the carrier belt B. This also permits the pressed folded garments to be transferred atwise horizontally to the packaging operators tables.

It is clear now that the folded garments are always moved atwise horizontally from the folding tables to the continuously moving carrier belt to the packaging or boxing tables. The entire pressing operation as will appear more clearly later is automatic thereby avoiding the necessity of employing las heretofore, operators for starting and stopping the machines for each folded garment pressed.

A stock table 24 may, left hand end of the machine to support a supply of envelopes, etc., or packaged goods as desired.

The method can be practised best and the advantages of the system can be obtained more fully by the use of a presser shoe S shown in detail in Figs. 3 and 4.

Referring to Figs. 3 and 4, the presser shoe S, which is rectangular in plan as shown in Fig. l, may be of any suitable construction and could be a single solid block of any material, of metal in case it is to be heated by burner jets playing on its upper face. It is desired however to make the shoe hollow to receive any suitable preferably electrical heating elements 25, Fig. l, regulated from any suitable known control box 26 as indicated. It may comprise identical side members 30 and 31, Figs.

3 and 4, a back piece 32, and a bottom smoothing plate 33, integrally cast or connected together in any suitable manner, and a removable top cover plate 34.

The lower edges of the side members and the lower face of the smoothing plate are preferably curved at their forward ends as shown in Fig. 4 to press the folded garments against the carrier belt B, the surface of which is preferably rough, to be carried by the carrier belt against and under the smoothing face of the presser shoe to be smoothed, pressed, ironed and compressed thereby without disturbing the folded condition of the garment as byy pushing back the front end of the folded garment. The presser shoe S is preferably longer than thewidth and length of the folded garment so as to press on the entire area of the folded garment at some time during its movement under the presser shoe. By the means about to be described, the presser shoe may be raised and lowered for different thicknesses of folded garments and may be inclined to the rear so that the pressing pressure will irtilcrease as the folded garment is moved past the presser s oe.

The presser shoe S, Figs. 3 and 4, is supported on plates and 41 located laterally of the sides of the presser shoe supported respectively on compression springs 42 and 43 seated in recesses in the table MT and surrounding bolts 45 and 46 suitably anchored against'the upward movement in the table MT and pasisng loosely through apertures in the plates 40 and 41. The upper ends of the bolts are equipped with nuts 47 and 48 as shown bearing on the upper faces of the plates to lower the presser shoe against the expansion of the springs to provide the proper spacing of the presser shoe from the carrier belt for folded garments of different thicknesses and to position the front end of the presser shoe farther from the `carrier belt than its rear end to prevent pushing up the forward edges of the folded garments as they `are carried below the presser Vshoe and to increase the pressing pressureras the folded garments are carried toward the rear end of the presser shoe. i

In lorder that the presser shoe may be `lifted by the folded garments to prevent pushing together of the folded garments and in order also to regulate the pressure of if desired, be provided at the the presser shoe on the garments, the presser shoe S is indirectly supported on the plates 40 and 41 by means of plates 50 and 51 resting on the plates 40 and 41. Each plate 50 and 51 is provided with perforated lugs 52 and 53 to support rods 54 and 55. The rod 54 is supported in the lugs S2 and extends through apertures in the side Walls of the front end of the presser shoe and the rod 55 is supported by the lugs 53 and extends along the rear end of the presser shoe and under lugs 56 on the rear ends of the side plates of the presser shoe. The presser shoe is connected to the supporting plates 50 and 51 by any quickly releasable hook lock connection 58 pivoted on a rod 63 supported in upstanding ears 64 on the upper edges of the rear ends of the side plates of the presser shoe and movable into and out of the locking engagement with the rod 55 carried by the rear ends of supporting plates 50 and 51. By means of this constructon the rear end of the presser shoe may be lifted away from the carrier belt to prevent overheating of the carrier belt at the con clusion of a run of the machine, and for inspection and cleaning of the smoothing surface of the presser shoe. Any suitable means (not shown) may support the presser shoe in raised position.

The supporting plates 50 and 51 are held against movement longitudinally respectively by the bolts 67 and 68 suitably anchored against upward movement in the table MT as shown and passing loosely through alined apertures in the plates 40 and 50 and 41 and 51, and which at their upper ends are threaded to receive tension adjusting nuts 70 and 71 for adjusting the tension of springs 73 and 74 to regulate the pressure of the presser shoe on foldedgarrnents being pressed. The springs 42 and 43 are strong enough to raise the presser shoe under control of the nuts 47 and 48. The springs 73 and 74 are weaker to permit the presser shoe to rise as a folded garment is carried under it and are so adjusted as to press the presser shoe against the folded garment with the pressure necessary to produce the desired appearance and compactness of the folded garment.

The machine is prepared for operation for pressing a run of folded garments of the same weight by raising or lowering the presser shoe S as required. The front end of the presser shoe S is positioned under control of the springs 42 and 43 and the adjusting nuts 47 and 48 at the front ends of the supporting plates 40 and 41, to receive the folded garments and press them against the carrier belt B without disturbing the folded condition of the garment. The rear end of the presser shoe S is raised or lowered by means of the springs 42 and 43 and the adjusting nuts 47 land 48 at the rear ends of the supporting bars 40 and 41 to incline the presser shoe toward the rear to cause the folded garment to be compressed under increasing pressure as it is carried along the lower surface of the presser shoe and to limit the degree of compacting that may be effected by the presser shoe.

The springs 73 and 74 engaging the front ends of the supporting plates 50 and 51 are then adjusted to yield to permit the presser shoe to be raised by the moving folded garments without disturbing the folded condition of the folded garments and at the same time slightly compress the folded garments and press them into frictional engagement with the carrier belt B to be carried thereby under the presser shoe S. The springs 73 and 74 engaging the rear ends of the supporting plates 50 and 51 are `adjusted to control the final pressing and compacting pressure of the presser shoe S on the folded garments.

It may be necessary to set or reset thecontrol box for the heating elements 25 to heat the presser shoe S to the temperature best suited for the weight or character of the garments to be pressed and the rate at which they are pressed. ALikewise it may be necessary or desirable to adjust the speed of travel of the carrier belt B to control the length of time during which the folded garments are subjected to heat and pressure by the presser shoe. The presser `shoe S may be pivoted away from the carrier belt as it is brought up to the desired temperature. In

, Aany event, the carrier belt should be in motion whenever the presser shoe is in operating position to prevent injury to the carrier belt.

After the machine has been started, the folding operators fold the garments on the folding tables and transfer them horizontally flatwise onto the slow moving carrier belt in any spaces available or in spaces and zones to each folding operator. The carrier belt then carries the folded garments horizontally llatwise under and across the smoothing face of the presser shoe into the delivery region where the packaging operators remove them preferably horizontally atwise from the carrier belt to package or pack them as desired. 'Ihe pressing operation is entirely automatic requiring no press operator and no attention from any of the folding or packaging operators, except to start and stop the machine and pivot the presser shoe away from the carrier belt at the end of a run.

The invention has been described in detail with reference to a specific embodiment of mechanism well-adapted for attaining the objects stated.
