Figure 9 is a view in .side elevation of the device shown in .Figure 8.

Referring to the drawings, and particularly Figures 1, 2, 3 and 4, the. base 1 has mounted thereon the hollow frame 2 having'an outwardly extending arm 3, thus defining a U-shapedframe forsupportinga pressing head 4 and a bottom roll'5 for pressing seams therebetween. The outer end of the arm 3 is provided with a vertically disposed extension 6 provided with a guide slot in which a guide 7 on the pressing head 4 is vertically'reciprocable. Up and down motion of the pressing head is obtained by reason of its connection at 27 with one .end of. the lever 8, which lever is fulcrumed or pivoted at-9 on the frame. arm 3, the other end of the lever 8 being pivotally. connected at 10 with an operating rod llwhich is vertically reciprocable through an opening 12. in therbase 1. The operating rod 11 has an eye 13 to which may be connected a chain for hand operation, orknown treadle. linkage for foot operation, or suitable knownconnection's for knee operation. A spring 14 surrounds the operating rod 11 for part of its length and is adjustably compressed between abutments defined by thebase 1 and a washer 15 and nut 16 and lock nut '17 threaded on the upperthreaded portion 11 of the operating rod. 11. By manually adjusting the nut 16', the pressing head 4 may be varied in' its pressure when in its down or pressing position.

Connected to the trame arm 3 at a pivotal connection 18'is an element 19 having a threaded end 20 carrying nuts 21 and 22 movably adjustable thereon. A lever arm23 has an opening or hole on one end thereof through which the threaded end 20 of the element 19 passes and thus slidably connects elements ,19 and 23. The other endof arm 23 is pivotally connected at 24 to an upstanding bifurcated extension of the portion 25 integral with the block 26. Carried by the arm 23 and affixed thereto is an element 28 having a stud 29 defining one end of a valve stem 38 which has a tapered lower end 31 adapted to seat in the opening of valve seat 33 in opening 61 of the block 26. The portion 25 is provided with a gland 32 to prevent steam leakage around the valve stem.- The block 26 is provided with the steam opening 61 which communicates with the steam coil 34in the head, which latter is supplied with steam through the inlet pipe 35. A narrow duct 36 in the block 26 communicates with an elongated duct 37 which passes through the head adjacent its outer edge and terminates in the .extravasation openings 38. The steam coil 34 is surrounded with electric resistance elements 39 and tilsuitably electrically insulated therefrom.

The roll-5 is covered by felt or other suitable material 41 and rotates on the shaft 42 journalled and supported intrunnions 43. Power to rotate the shaft 42 is transmitted from shaft 44 through the gearing defined by gears 45, 46, shaft 47, and gears 48 and 49, respectively. It will benoted that gears 45, 46 and 48 are all housed in the hollow frame 2 which may be suitably supported with its base -1 upona pedestal or other suitable means (not shown) at the socket 58. By known clutch control, the power through the gearing described to the roll 5 may be supplied at the will of the operator.

The pressing head 4 is in the form of a hollow box with a straight side 50 having a tapered portion 51 which terminates in a relatively small bottom 52 of slight curvaturehaving openings38 where contact is made with material to bepressed. The head 4 has a side 53 opposed to side 56, the side 53 terminating with an inclined face 54 which ends atan abutment 55 perpendicularly disposed with respect to the bottom 52. A seam spreader is shown at 59 located above the apron 60.

Referring to Figures 8 and 9, the roll 5 is supported to rotate in a direction at right angles to the direction of rotation of the roll in Figure 1. This roll is driven by translated motion of worm gears 56 and 57 from rotating shaft 62, and this roll arrangement is convenient for press ing seams in garments that may not be conveniently seampressed by the arrangement shown in Figure 1.

It will be observed from the figures, and particularly Figures 4, 5, 6 and 7, that the steam supplied from any suitable source enters the head through the pipe 35 and circulatesthrough the helical steam coil 34 until it reaches the valve, which controls the steam supply that enters the opening 61 and passes through the duct 36. The pipe 35- is provided with a manually operated valve (not shown) to cut oif the steam supply entirely, if desired. The. electrical resistance heating means surrounding the steam coil is adapted to superheat the steam in the coil and/or to heat, or add heat to the pressing head. The electrical heating means is manually controlled by any suitableelectrical switch arrangement (not shown) to give low, medium or high heat, or to be switched off altogether, as desired. The valve means associated with the block 26 controlling the steam is preferably pre-set by adjustment of 21 and 22 and/or thread 29 on valve stem 30 allowing a minimum of steam vapor to flow through the head continuously thereby keeping the head continuously heated; when the head is down on the work, more steam vapor is supplied to the duct 36 and its terminal outlet 38.

The operation of the machine will be evident from the description herein. The seam to be pressed is inserted between the head and roll by pulling the operating rod 11 downwardly against the action of the spring 14, which tends to maintain the head 4 in down position under suitably adjusted spring pressure. Power derived from any suitable source such as an electric motor (not shown) is caused to rotate the shaft 44, through the medium of any suitable known clutch control, thereby causing positive rotation of the roll 5, which feeds the seamed material between the roll and head. Where steam pressing is desired, steam issues from the openings 38 in the pressing face of the head, the amount of steam issuing through the pressing face being controlled by presetting the valve in the block 26, which valve functions to open when the head is in down position and to close when the head is in up position. When valve stem 30 is in open position, steam enters pipe 35, circulates through the coil 34, then through the opening in the seat 33, then through the duct 36 and emerges at openings 38. When valve stem 30 is in closed position, the

' tapered portion 31 is seated on valve seat 33, and steam is trapped in coil 34 until the operator brings valve 30 in open position again.

With the head 4 in down position, the unseating of the valve stem at its tapered portion 31 opens the port of the seat 33, and the steam can then pass into the duct 36 and ultimately issue through openings 38. The valve stem 30 may be pre-set to permit proper operation of the valve for steam supply. Where superheated steam is required, electrical current is supplied to the electric resistance elements 39 and 40, and their proximity to the steam coil 34 effectively superheats the steam passing therethrough. Where steam pressing is not desired or required, hot pressing alone may be done by cutting off the steam supply before it enters the pipe 35 and heating the pressing head by the electrical heating means contained therein.

The lever arm 23 may be disconnected from the element 19 and thus permit the steam valve to be operated entirely by hand separately from and/or independently of the head reciprocating movement.

The seam pressing machine herein described and claimed is a compact, simplified structure capable of scam pressing with dry heat, steam alone, or superheated steam. Its simplicity lends itself to economical manufacture and its operation is flexible, economical, and easily carried out and controlled, thus effecting economies including substantial labor-saving.

Suitable modifications and variations may be made in the details of the various elements and in the machine without departing from the spirit and scope of the invention as defined in the accompanying claims.
