Application January 28, 1954, Serial No..406,74 1 7 Claims. (Cl. 38*15') This invention relates to a pressing device which has particular application to the problem of pressing belt loops after they have been prepared by the blindstitch type? of sewing machine. While the device is -particlk larly important in this application it is not limited thereto and-can be used in' other applications.

Belt loops for trousers are conventionally prepared by doubling a piece of fabric bringing thedoubled portions together at about the center line. The loose ends are then sewn together by a blindstitch machine. This type of stitch causes the ends to be secured together but causes no visible stitch marks to show onthe upper side ofthe belt loop. The conventional process thusproduces .a. long: strip of belt loop material. which is then cut into convenient lengths and sewn in place upon a pair of trousers. I 7

It has been found, however, that the strip of belt. loop material, as it leaves the machine, is in unpressedconditionand cannot be directly applied to the pair of trousers. It has therefore been common. practice to press thebelt loop strip as it is taken from the machine and then, after pressing, to cut it into convenient lengths.

The conventional sequence of' steps, however, involves three separate operations which, in these times of high labor costs, are unsatisfactory. V

The present invention permits a strip of belt loop material to be manufactured and'pressed in one operation,

and, where the novel cutter of this invention is also used, to also cut the strip of pressed belt loop material into the sizes required. The operation-is completely automatic and'can be performed with only semi-skilled labor.

Since the various fabrics of which belt loops are made have different temperatures at which they should be pressed the device is also provided with temperature controlling means as will be subsequently explained.

Briefly stated the invention comprises a feed member, a plate member provided with an. opening therein adapted to emit steam, a heating device adjacent to the plate member, and a presser member in operating relationship with the plate member. The invention may. also include a cutter member spaced from the plate member and in operating relationship with the feed member.

In the preferred modification of this invention the heating device is in abutting relationship with the plate member and temperature controlling means are provided in operating relationship with the heating device. A steam control valve is also provided in the preferred modification to control the emission of steam through the opening in the plate member.

It is preferable to drive the feed member by means of the sewing machine to which the pressing device is secured so that positive action may be obtained.

The invention will be further described by reference to the accompanying drawings which are made a part of this specification.

} sewing machinell is adapted to form belt loop -12 by the conventional. blindstitch process. Belt loop 12 passes through openinglll inshield member 14 which is secured to plate rnember' 15. Plate member 15 is of appreciable thickness and is provided with

intercommunicating steam channels

16, 17, 18, 19 and 20. Steam channel 20' is provided withopenings 21 which communicate both with steam channel 20 and upper surface 22 of plate member 15. Plate member 15 is also preferably provided with cut-out portion 23 and openings 21 communicate with cut-out portion 23. Belt loop 12 is adapted to fit into cui=out portion 23.

Presser member 24- overlies plate member '15 and is adapted to produce pressing action upon belt loop 12. Presser-member 24 is normally ept in operating relationship with plate 15 by means of' springs 25 which are supported upon screws 26. j I

In order to prevent damage to the belt loop passing between plate'member 15" and presser member 24 presser member 24 is formed with ears 27 at each end thereof. Steam passes through steam channels 16-20 from a steam producing device of conventional type (not shown). The passage or the steam into channels 16.20 and thence thrtilig'h openings 21 is controlledby, valve 28.. Valve28 operated by theidownward movements of arm 29'which is seeuredto arm. 30 which in turn is secured to a foot treadle (not shown). Arm 31 bears spring 32 which causes arm 29 to return to its normal position when the pressureon the foot treadle is released. Adjusting screw 33 is. provided to; control the tension ofspring 32.

29is' pivo'tedabout support 34v and is held in place by screw/ 35. A drain valve is located at the lowermost point or channels 16-20'. Cock-91 controls the opening and closing thereof. Valve 90 isnormallj' theinvention hown closed but is opened whenever it is desired to drain the if condensed water from channels 16-20.

Feed roller 36 is driven by shaft 37 which in turn is secured to bevel gear 38. Gear 38 is secured to bevel gear 40 which in turn is secured to" shaft 39. Shaft 39 is secured to gear 41 which is driven by worm 4 2. Worm 42 is secured to shaft 43 which also bears pulley -44 Pulley 44, which is a drive roller, is driven by belt 45 which is driven by the sewing machine 11. Shaft 39also bears gear 46 which drives the cutter ofthis invention as will be subsequently explained. "Shaft 39, gear 41, worm 42, and shaft 43 constitute a speed reducing device.

Feed roller 47 abuts feed roller 36 andbelt loop 12 passes between

rollers

36 and 47. Roller 47 is secured to arm 48 which is pivotally movable upwardly about pivot 49a. Arm 48 bears link 49 which is securedwithin recess 50. Link 49 is also secured to link 51 which is secured to presser member 24. i

Presser member 24 and feed roller 47 aremoved out of operating relationship with plate 15 and feed roller 36 respectively by the upward movement of arm 48. Spring 52 is supported upon shaft 53 and its tension is controlled by adjusting screw 54. Operating handle 55 raises and lowers arm 48.

Support 56 is also provided to hold belt loop 12 in place and cause it to flow smoothly'into a receptacle (not shown).

Plate member 15 is preferably formed with an additional cut-out portion 57 at the underside thereof. Heating device 58, which is preferably an electrical heating element, is disposed within cut-out portion 57. Heating element 58 is secured to a conventional thermostat 59 which is preferably of the compound bar adjustable ,type. Handle 60 varies the spacing of the contacts of the compound bar within thermostat 59 and thus controls the temperature that the heating device may assume. The heating element and thermostat are secured to a conventional power line (not shown).

The pressing device of this invention may also be equipped with a novel cutting device as shown in Figs. 13, 14 and 15. If this device is used the belt loops provided may be cut into the lengths desired in one operation. In this modification cutting table 61 is provided. Reciprocating cutting blade 62 abuts against cuttingtable 61 and cuts the belt loop as it moves downwardly. Cutting blade 62 is secured to shaft 63 which in turn is secured to arm 64. Arm 64 is in turn secured to arm 65 which is secured to operating member 66 of solenoid coil 67. Switch 68 actuates solenoid coil 67. Swith 68 is actuated by contact 69 which is moved into and out of engagement by cam roller 70. Cam roller 70 is driven by drive gear 46 which is driven by shaft 39 as previously explained. Drive gear 46 is changeable so that the speed of engagement of cam roller 70 with contact 69 can be controlled and thereby control the number of times that blade 62 moves downwardly. Since belt loop 12 is moving at a constant rate the size of the belt loop produced can be simply controlled.

While the operation of this device has been made clear by the foregoing description a graphic illustration of the operation of this device, including the cutter, will now be given.

Sewing machine 11 is operated and forms a continuous belt loop by the blindstitch method. As the loop 12 moves from the machine arm 48 is moved upwardly placing presser member 24 and feed roller 47 out of operating relationship with plate 15 and carrier roller 36. Prior to the operation of sewing machine 11 drive gear 46 which engages cam gear 70 and thus changes the period of reciprocation of cutter 62, has been selected of a size and number of teeth adapted to produce the size of belt loop desired. In addition thermostat 59 has been set to the fabric of which the belt loop is composed so that the correct heating temperature of plate 15 is produced. I V t With arm 48 in its upward position belt loop 12 is placed between

rollers

36 and 47 and plate 15 and presser member 24. After this is done arm 48 is moved to its normal downward position so that belt loop 12 is moved by the action of

carrier rollers

36 and 47 and is pressed by presser member 24 bearing against plate 15. Steam valve 28 is then actuated by the depression of arm 29. Steam then flows out of openings 21 and smooths out the irregularities in belt loop 12. Immediately, however, the heat'of plate 15, which has been produced by heating element 58, dries the belt loop and removes the con densed water from the belt loop. The belt loop is also simultaneously pressed by being passed between presser member 24 and plate member 15.

As the pressed belt loop leaves plate member 15 and presser member 24, and after it passes between

carrier rollers

36 and 47 it passes over table 61 and then comes in contact with cutter blade 62 Every time cutter blade 62 moves downwardly it cuts off a portion of belt loop 12. The reciprocating downwardly movement of blade 62 is controlled by gear 46 which meshes with gear 70 and thus controls actuator 69 which opens and closes switch 68 actuating solenoid coil 67 and causing operating member 66 to move reciprocatingly. When switch 68 is open return spring causes shaft 66 to move to its open position. Thus, as shown, the machine carries out the intended purposes.

The foregoing specific embodiments of this invention as set forth in the foregoing specification and drawings are for illustrative purposes and for purposes of example only. Various changes and modifications can obviously be'made within the spirit and scope of the invention and would occur to those skilled in this art. The scope of the invention is determined from the appended claims.
