lRoNlNG-MACHINE.

SPECIFICATION forming part of Letters `Patent No. 624,755, dated May 9, 1899.

Application filed September 18, 1897. Serial No. 652,110. (No model.) A

machines operated by steam-power, and has for its object to construct a machine for ironing collars and smoothing cloth.

. With the above and other objects in view the invention nally consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed out in the claims. r

In describing this` invention in detail reference is had to the accompanying drawings,

forming a part of this specification, and` wherein like igures and letters of reference indicate similar parts throughout the several views, in which- Figure 1 is a front view of my improved ironer. Fig. 2 is a side view of the same. Fig. 3 is a top plan view. Fig. 4 is a top plan view with the iron and ironing-board removed. Fig. 5 is a rear elevation. Fig. 6 is a rear view of the iron.

Fig. 15 is aside view of a modified form of rockerarm.' Fig. 16 is a perspective view of a modified form of burner. Fig. 17 is a front view of a modified form of table-operating mechanism.

Referring now to the drawings by reference numerals and letters, 1 indicates a frame for the machine,which is mounted upon a suitable base 2. Secured to the top of the frame 1 is a 1ing of the plates.

vertical shaft 3, the upper end 4 of which is reduced in size and has mounted thereon a rocker-arm 5 for operating the smoothing-iron. This smoothing-iron is somewhat segmental in form and is composed of an underneath plate 6, forming a smoothing-face, and a top plate or cover 7, which are secured to the sides 8, thus forming a space between the top plate or cover and the underneath face, in which is Varranged a gas-burner, by means of which the iron is heated. This burner consists of a tube 10, provided with openin gs 11, and is arranged `within apipe 14E, having a cut-away portion 15 ladjacent to the openings 11, which permits the gas to escape from the pipe 14 as it emerges from the openings in the tube 10 and allows the same to become mixed with air within the iron, and also with the air which may be allowed to enter through the end 17 of the tube 10, while the gas enters from the opposite end or end 19 of this tube 10. The tube 10 is supported by two blocks v12, which are arranged between the top plate 7 and the under plate 6 and which are provided ou their one face with the groove 12fl to receive `the securing-bolts 13, passing through the top plate 7 and engaging the under plate 6. This construction serves to bind the two platesv firmly against the sides and prevents warp- Q Rigidly secured to the upper face of the top plate 7 is a block 9, which may also have a bolt 13 passingfthrough the same and through the plate 7 and engaging in the plate 6 for the same purpose heretofore described. This block 9 is adapted to receive one end of the rocker-arm 5, while the other end of the said arm is rounded, as at 5", anc has journaled thereon a swivel 5f. l

Secured in the rear plate of the frame is a stationary shaft 30, having journaled thereon the bearing-block 29,in the upper end of which is pivotally mounted the shaft 23, having a bifurcated end 28, that engages the swivel 5a for operating the rocker-arm 5 of the smoothin g-iron. Connected to the sides of the block 29 at their upper ends and to a block 32 at their. lower ends are the bars 31, forming guides forthe sliding block 39, which is mounted upon the wrist-pin 33a of the crankarm 3S, said crank-arm being connected near its other end to a shaft 33, which is journaled IOC in the two sides of the frame 1. This shaft 33 has mounted thereon within the frame a gear-wheel 34, which meshes with a smaller gear 35, mounted upon a drive-shaft 36, likewise journaled in the frame near the base thereof, and which has mounted on its one end the drive-pulley 37.

The ironing-table is operative vertically, so as to be elevated into contact with the smoothing-iron when desired. The table consists of the plate 27which may be provided with a suitable padding on its upper face to receive the article to be ironed andis supported by means of -shafts 20, journaled in the frame 1 and projecting beyond one side thereof. On each of these shafts is mounted a pair of cams 21 22, which support t-he table, the latter being prevented from lateral movement by means of lugs 26, secured to said table and projecting downwardly therefrom outside of the shafts 2O and between each pair of cams 21 and 22. Rigidly connected to said shafts 20 outside the frame 1 is a pair of levers 23,

the lower ends of which have pivotal] y connected thereto a horizontal bar 24, and pivotally secured to this bar 24, at a point centrally of the same, is a curved lever 25, to the end of which is likewise pivotally connected the lever 25, to which is attached a treadle or other operating lever. (Not shown.)

In order to hold the table irmly in position and also to assure the returning` of the same to the lowered position, I attach to the under side of the table and to the base 2 a retracting-spring 26a.

In Figs. 12, 13, 14, l5, and I6 I show a modified form of smoothing-iron and gas-burner. In this construction the iron consists of a plate 44,which acts as the smoothing-face, and atop plate or coverl 45,which is supported -by the sides 46 and connected by bolts 47 or other suitable means. The ends of this form of iron are closed by plates 50, the ends of which are beveled to conform to the curvature of the sides 46. At the front of the iron these beveled ends abut against the inner face of the front side 46, and at the rear of the iron the inner face of the plate 50 abuts against the ends of the rear side 46 and are held in engagement and in their position by means lof springs 48 49, connected at their one end by a common rivet 48. The springs 48 lie in engagement with the outer face of the rear side 46 and with the rear end of the end plates 50, while the springs 49 are curved so as to bring their free ends into engagement with the outer face-0f the said end plates 50. This construction permits a ready removal of the end plates 50, if so desired, and to facilitate such removal I provide the end plates 50 with suitable handles 51. B y forcing these ends rearwardly it will be observed that the ends maybe at once disengaged and removed from the iron. In order to provide means for lighting the gas at the burner without removing these end plates and to permit the heat to escape, I provide said plates with openings 506, as shown. In this form of iron the burner is composed of a cup 53, with which engages the pipe or burner tube 53. This cup is provided with interior screw-threads to receive the sleeve 54, passing through the top plate 45 and having formed integral therewith a flange 54h, by means of which the sleeve may be secured to the top plate. Connected to the upper end of the sleeve 54a is a gas-supply pipe 51, and connected to the side of said sleeve is an air-supply pipe 52. The collar 54C is connected to the shaft 54 and is pivotally mounted on the sleeve 54a.

ith either form of iron shown I may employ a friction-roller 55,whieh is mounted on a shaft 54, secured to the collar 54C or to the block 9 and travels upon a segment-shaped -track 456, that is supported by standards 57,

mounted in the top of the frame. This friction-roller serves to prevent binding of the iron when a heavy thickness of material is placed between the same and the ironingtable.

In Fig. 17 I have shown a modified form of operating mechanism for elevating and lowering the ironing-table, which consists of a pair of levers 40, pivoted at their upper end, as at 4l, to the frame 1 and carrying cams 42 to engage said table. The lower ends of these levers 4l are pivotally connected by a rod or bar 43, to which is rigidly and centrally connected an angle-shaped lever 43, and pivotally connected to the other end of this angleshaped lever 43a is a treadle or other suitable operating-lever 44, which may be pivoted, as at 44, to the frame.

In order to impart a forward movement to the table 27 simultaneously with the upward movement of the same, I secure to the underneath face of the said table a pair of hangerrods a and connect the same at their lower extremity by a bar a2, to which is secured an arm a3, which is inclined at a pitch of about forty-five degrees. Secured to the frame 1 is a standard a4, and journaled in this latter and the frame 1 is a shaft a5, upon which is rotatably mounted a roller a6. (Shown in dotted lines.) When the cams are operated to elevate the table, this roller rides upon the inclined arm (t3, and thereby imparts a forward movement to the table simultaneously with the upward movement or elevation thereof.

It will be readily observed that upon revolving the drive-pulley 37, which is rigidly attached to the shaft 36, carrying the gear 35, the gear 35 will operate the gear-wheel 34, which, being rigidly mounted to the shaft33, carrying the crank-arm 3S, to which is pivotally secured the slide-block 39, will move the sliding block in the guide-bars 31. On the circular movement of this sliding block 39 it will rock the bars 31, and owing to the bifurcated end of the shaft 28, which is pivoted to the upper part of the bearing-block 29, and the swiveled end of the rocker-arm, which operates in the bifurcated end of the shaft 2S, it will give to the rocker-arm an os- IOO lrol

Geerts i a cillating motion, thereby operating the iron in the same direction as the rocker-arm.

The operation of the adjusting means for the table can be readily understood from the foregoing description thereof, taken in connection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

l. In an ironing-machine, the combination of a suitable frame, avertically-reciprocating table, cams for operating said table, a support secured to the top of the frame, a rockerframe whereby the crank-shaft is operated, substantially as shown and described. y

2. In an ironing-machine, the combination of a frame, a shaft 3 secured to the top of said frame, a rocker-arm mounted on said shaft, a smoothing-iron removably connected to one end of said rocker-arm, a burner arranged in said smoothing-iron, a pair of shafts journaled in the frame near its upper end and projecting beyond the same on one side thereof, a pair of cams mounted on the pro'- jecting portion of each of said shafts, a table supported by said cams and carrying lugs to engage between each pair of cams and retain the table in position, means connected to said shafts for operating the same and the cams to elevate the table and bring the same in contact with the smoothing-iron, and retracting means for said table, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
