To all whom it may concern: I

Be it known that I, GEORGE A. KIMBER,

- 'a citizen of the United States, and a resident of the city. of Chica o, in the county of Cook and State of I inois, have invented certain new and useful Improvements in Pressing-Machines; and I do hereby-declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

This invention relates more particularly to that class of pressing machines sometimes used in large tailoring establishments for pressing garments. v

The Ob]90t: of this invention is to afford a balanced construction whereby the iron is normally supported above the' boardto af ford a large clearance for the handling or manipulation of the work, but which permits the application of the iron at any point within its range of movement with maximum efliciency' It is also anobject of the invention, to afford a construction permitting wide range of movement of the iron both longitudinally of the board and transversely thereof with the iron at all times supportedfito conform to the surface to be pressed.

afford a construction in which the iron is moved rapidly and with slight application of power into engagement with the work after which the fina maximumpressure is applied with slight travel crease 1n pressure.

It is an ob'ect of the invention also to afford mechamsm insuring instantaneous release .from the article being pressed and to permit regulation of lpressure with the great est nicety to meet t 0 requirements of the work to be accomplished.

The invention consists in the matters hereinafter described and more fully pointed out and defined-in the, appended claims.

illustrating the means for adjusting pres sure and travel of the iron. Fig 5 isa section on line 5-5 of Fig. 2. Fig. 6 is a section on line 66 of in elevation. I

As shown in the drawings: A suitable under frame of cast metal or any suitable construction is provided embracing in the construction shown rear legs 1, and front legs 2, and horizontal rails 3, connecting said front and rear legs. Arranged between the 'pairs of legs is a triangular frame em bracing arms 4, which extend from near the middle of the back of the table'forwardly to near the front legs thereof and to which and the rails is firmly secured the tabletop 5,

.by means ofscrews, bolts, or other suitable means. As shown also, said frame is connected with the rear legs of the table frame proper by means of a rail 6, in the construc tion shown integrally united with said legs, and serving to bind all parts of theframe rigidly together. Extending downwardly from said triangular frame 4, at its rear is a sleeve7, integral therewith if desired, and rigidl -bolted on the rear side of said sleeve is a fi th leg 8. Rotatably jourhaled in said sleeve. is a tubular shaft 9, provided with a retaining nut 10, which bears against the I lower end of the sleeve and at its upper end It' s also an object of the invention to flanged peri herall and S11 orted u on ball or other einti-fricti'on bearir igs 11, ini erposed between the same, and the upper end of said sleeve to permit easy rotation of said shaft in said sleeve. Extending'rearwardly 1provided at Its rear end with a vertical s eeve 13, in which is slidably engaged a slip shaft 14, which at its upper end is provided with a transversely apertured knuckle'15, adapted Fig. 2, with the springs t4: receive therethrou h the pintle 16, which' extends through'said nuckle and the lateral lugs .17, at the rear end of the lever 18,:upon which the iron is carried. As shown, said slip shaft 14, is threaded-at its upper end and secured thereonisa spanner or any suitable nut 19, whereby saidslip shaft may be adjusted vertically-in the sleevejtherefor.

. Extending forwardly from the upper end of the sleeve 7,, above the roller bearing therefor, is a bracket 20, on the forward en of which is secured an upwardlyand rearwardly. directed "bracket 21. The lever 18, extends upwardly'and forwardly toward the front edge of the tableand for-the major portion of its lengthfrom I the front end thereof is tubular, as shown in gaged a short coupling 28.

bottom of said coupling extends a connect-' "ing rod- 29, provided with a flat head 30,

within said coupling whereby a slight rota- Fig. 2, to receive'therein the cylindric arm 22, on which the iron 23, is rotatably supported, as shown in Figs. 1 and 2. Extending through said lever at the rear end of said tubular portion thereof, and as shown, slightly atthe rear of the middle of said lever, is a pivot pin 24, on which is jour naled a bell crank-25, one arm of which extends downwardly to a point adjacent the rearwardly curved end of the bracket 21, and is movably connected therewith by means of a short link 26, the other arm of said bell crank lever is directed rearwardly and pivotally engaged thereon is a link 27, on the lower end of which is pivotally en- Through the tional movement of the coupling is possible with -.respect to said connecting rod. Said rod extends downwardly through the tubular shaft 9, and at its lower end is connected with a foot lever 31, which isfulcrumed 0n the leg 8,and extends forwardly beneath the horizontal frame bar 32, and is provided at its outer end with an enlarged foot plate 33, which projects sufiiciently beyond the edge of the table to enable the operator to apply his weight thereto.

Extending. through the downwardly extendin arm of the bell crank slightly at the rearo a line drawn from the pivot pin 24, to the pivotal engagement of the link 26,

with said arm, is a pin 34, and pivotally engaged on said pin are upwardly extendin rods 35, one on each side of said bell crank and which extend through the lever 18, and are each provided with a strong spiral spring 36, the compression of which is adjusted by means of nuts 37 threaded on the upper ends of said rods.

Supported at the front edge of the table and centrally, is the ironing board or buck 38, which, of course, may be of any desired or usual construction and is supported at a height for the most convenient application of the iron thereto. Supported on said lever '18, conveniently within reach of the operator is a cup or bowl 39, which may contain any of the accessories used by the operatorsistance until the iron is brought into en gagement with the material upon the board 38. At this point the lower ends of the tension rods 35, are brought more nearly into vertical alinement with the pivot pin 24. The iron now resting upon the material, the link and the pivot bearing on the bell crank therefor swings under the pivot bearing therefor on the bracket 21, affording a powerful knuckle or toggle and when pressed by the bell crank to the position shown in Fig. 3, enormously increases the pressure exerted by the iron-upon the board. When pressure on the lever 31, is released, the springs 36, under maximum compression, act to swing the bell. crank u wardly on the pivot pin 24, inasmuch as t e.tension rods 35, are connected out of vertical alinement with the pivot pin-24, and the lower end of the bell crank with the result of instantly swinging the iron upwardly to the position shown in Fig; 2.

Owing to the construction described any portioir of the board may be conveniently reached by the iron and the iron may be adjusted outwardly or inwardly in the tubular end of the lever 18, inasmuch as the cylindric arm 22, slides freely in the sleeved end of said lever. Inasmuch as a ball bearing is provided to support the tubul' r shaft on the sleeve 7, it follows that the ron may be swung from end to end of the board wit the utmost ease, and, owing to the construction described, may be brought into engagement with the material at any point on the board with very slight pressure and then by means of the bell crank before described the pressure may be enormously increased to the maximum efliciency required.

Obviously the machine may be adjusted for any thickness of material, inasmuch as the limit of downward movement for the iron may readily be regulate b the adjustment of the slip shaft 14, in its earing. Should the nut 19, be set up to slightly elevate the slip shaft the iron is then adjusted for thinner material. Should the slip shaft be lowered slightly in its hearing by the opposite rotation of said nut the maximum ownward limit of travel of the iron is decreased. Obviously the utmost ease of adjustment is thus afforded to suit the machine for the requirements of its use.

ossible Of course, I am aware that numerous dehave therefore shown but one of many possible embodiments of my invention. I do not, however, purpose limitingthis ap licatlOIl for patent otherwise than necessitated by the prior art as the exact embodiment of the machine to permit wide clearance when out of operation, rapid movementof the iron with a slight expenditure of power to engage the material and then enormous increase of pressure after such engagement may be efiected in numerous ways without neeted therewith and extending through the departing from the principles of my inventubular \shaft and having a swivel connection. tion with the-pressing mechanism.
