:SEAM-PRESSING iirAci'iiivE. I

Application filed May 22,

The present invention relates to. seam spreading and ironing machines wherein the flaps of a seam may be automatically turned back preparatory to the pressing operation,

' of the work by the operator as it is being pressed.

Another object of my invention i s to provide a pressing iron having a spreading nose of novel shape to spread the work, and a pressing surface to fit'the feed roll.

Other objects of my invent-ion will be apparent upon reading this specification, taken in connection with the accompanying drawings, in which Y F 1 is a front elevation view of mymachine;

Fig. 2 is a side elevation View thereof;

is a cross-section of the feed roll;

Fig. 4 is a top view of a. pressing iron used in my machine;

Fig. 5 is a side view, partly in cross-section, of the iron;

Fig. 6 is a cross-section taken along the line 6-45 of Fig. 5, looking in the direction of the arrow 7 is a perspective view of the nose of the iron Fig. 8 is a perspective view showing the nose, opening up a seam;

Fig. 9 is a view of the seam fully opened up and in process of being pressed; and

Fig. 10 is a cross-section of the upper part a of a modified form of feed roll.

Referring now in detail to the drawings, 10 represents a table having the top 11 on which is secured the supporting frame 12, the feed roll assembly 13 and theelectric motor 14;

Mounted on the frame 12 is a combined pressing iron and seam spreader. This com-' bination consists of the pressing iron 15 which is provided with a nose 33, the underside of which is of arched construction having a central projection 34 therein adaptedto enter between the flaps of the seam. The arch of 1926. Serial 130,116 904."

the nose is gradually modified untilit reaches the vanishing line in the cylindrical surface of the iron. a

The iron'is provided with a frame portion 36 adapted to fit over the pressure vplate 37.

This pressure plate .is intimately connected PATENT O C with the iron'by screws 39, and covers the heating element 37. cured to'the pressure plate 37 by the screws 40. The operative fpart'of the iron is reduced at 38 for the purpose of centralizing the heat The frame 36' is so and directing the same to the place where it is needed,name1y, at the planes of pressing, the breadth of the reduced iron part 38 being governed by the size and character of the work for whichth'e'sa me may be specifically made. Current issupplied to the heat unit through electric terminals 41 in the usual manner. v

The iron assembly is provided with an attaching lug 42 which is secured to the re} ciprocable rod 16 mounted to slide in suitable hearings in the frame 12 of the machine. A

spring 23 is mounted on the rod 16 and adjustment nuts 24 are in threaded relation with said rod for the purpose, of adjust ing the compression of the spring 23/ Swiveled in the frame of the machine 19 is an arm 18to which is linked the upper end of the rod 16, through the link 17. At the upper end of the arm 18 is swiveled a rod 20 embodying a turn buckle 21 and operated by a treadle 22. The spring 23 normally holds the iron 15 in raised position away from the work and from the feed roll 27. 7

The feed roll 27 is mounted to rotate with the shaft28. This shaft is energized from an electric motor 14 having a pulley 46 on its armature shaft over which the belt 142 travels, driving the pulley 29 with the shaft 30. A chain of reducing gears in the gear box 31 is driven by the shaft 30 which gears transmit motion to the shaft 28 and through it, to the feed roll 27. A shaft coupling 32- is includedin the shaft 28. i

The feed roll'27 is composed of a resilient,

smooth material having a supporting hub 43.

. material is adapted to serve as an element in effectively pressing the seam and, at the same time, permits theretarding of the work between the pressing iron and the feed roll without imparting an undesirable shine or gloss to the work. The feed roll is secured to and reinforced bythe hub 43 which is keyed to the shaft 28.

In Fig. 10 the feed roll is shown as composed of a wheel having a grooved periphery 4:7 with a feed ring 48 of fiber or other suitable material seated in said groove. A clamping member 4L9 is secured to the folly of the wheel, as by screws 50,and forms one side of the groove a7. The feed ring 48 is made of such width as to be held snugly in the groove &7 when the clamping member 4:9 is screwed in place, thereby preventing the feed ring from accidentally leaving the wheel or shifting in the groove.

The feed ring 48 is preferably composed of ordinary unwoven vulcanized cellulose fiber. Materials made of a canvas or paper base and bound by a phenolic condensation product, and also any material other than'paper or canvas belonging to the general fibrous group, which is distinguished by strength and ma chinability, may be used.

Inorder to open and press the seam on my machine, a pressing iron is heated in the usual way and the work is fed between the revolving feed roll 27 and the iron 15. A treadle 22 is then depressed between a fulcrum M and a rod connection 45, bringing the pressing iron in contact with the work. The projection 34 of the spreaderentersbetween the flaps of the seam and separates the seam, and the modifying arch of the spreader continues such separation until the spread seam arrives at the vanishing line of the arch and projection in the operative portion 35 of the iron when the side flaps are fully turned back. The work then continues through the machine between the pressing iron and feed roll. The degree of pressure may be regulated by the operators foot for such purpose. The revolving feed roll 27 carries the work past the depressed iron upon the seam in its travel and successively presses the work, which steps are continuous and Without any clearance or relief in the iron between the opening of the seam and the pressing of the work,

thus obviating any tendency of the seam closing again before the ironing thereof takes place. The smoothness of the feed roll promotes shifting or retarding of the work by the operator when desired, without the work being glossed thereby.

I. have described and shown what I believe to be the best embodiment of my invention. I do not wish to be limited to the em bodiment shown, but what I desire to cover by Letters Patent is set forth in the annexed claim.

What I claim is:

In a seam pressing machine, the combination with a feed roll, of a pressing iron having a pressing'surface complementary to the surface of the feed roll, and also having a tip portion in advance of the pressing surface adapted to separate the seam and to flatten it and to guide the seam tothe pressing iron, said tip including a thin pointed nose having lateral faces which are substantially vertical and parallel at the forward end of the nose and which incline increasingly outward toward the rear of the nose, and finally merge into the pressing surface of the iron.

In testimony whereof I have affixed my signature to this specification.
