To` all whom fitmay concern:

` Be it known that I, JOSEPH' GROSS, a citizen` of the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented a new and useful Improvement in Machines for lPressing Clothes, of which the" following is a specification.

This invent-ion relates to a machine forl pressing clothesand similar articles.

rllhe object of the invention 1s to give great power tothe pressing mechanism and correspondingly increase the strength of the parts to properly sustain the application of this power while at the same timepreserve lightness, simplicity 1and cheapness of construction; andfurther to give a nice` ad# justment to the iron and to the power .mechanism by which it is operated.

The invention consists substantially in the construction and arrangement hereinafter described and more particularly pointed out inthe claims.

Like reference letters designate the same parts in theseveralgures of the drawings, in which,

Figure 1 illustrates `the machine in side elevation and at rest. Fig; 2 illustrates t-he l machine in side elevation with the parts in `active position. Fig. 3 is Ta transverse vertical section of the table and operating mechanism beneath the same on the line c, a, Fig. 1`. Fig. t is atop plan view of the machine. Fig. `5` is a detailed. view-of the inside elevation of the iron. Fig. 6 `is a frontvelevat-ion. of the iron with its joint inl verticali` section on the line el, d, Fig. 5, and showing the dillerent positions in solid and dotted lines. Fig. 7 is-a` horizontal section on the line e, e, Fig. l, showing the toggle joint in the plan from the top. Fig.

8` is `an enlarged detail view of a part of the rocker` arm and its connection to `the table and to the middle arm.V Fig. "9 is an enlarged detail sectional view ofthe connections between thetreadle bar and theevener link. FignlO` is lan enlarged detail View in perspective of the evener link;*aindFig. llis a detail viewk of thenpress buck` with the` table in section and. the ends of the buck. broken away.

InFig. l ofthe vdrawings.there is show-n in plan" theseveral parts of the machine, and. it `will be 'noticed' that theA press buckis wider at one-end than lat: the `other andl in the present instance this pressingbuck is made reversible, `that is, it can be turned:

by adjustment the smaller end maybe pre sented to the operators right hand, thus making it very convenient for him in the operation of pressing different parts of the garment and a great saver of time. f This reversal is epected in the present instance by loosening the thumb nut shown in Fig; l1. It will be seen that the thumb `nut g is arranged tobear upon the walls 7L ofan elongated slot in the base of the supporting frame of the press buck C, and is adjusted on the threaded end of the bolt-z' which is secured to the table Dand passes up through the slot in the base of the press buck. By loosening this nut the base of the buck, to-

gether with the buck, may be reversed and clamped to the table by tightening the nut. This is manifest-ly a very simple operation, which the operator can perform almost instantly, and thus adapt theposition` of the board to his convenience. Of course, in pressing garments the necessity for reversing the press buck arises very frequently and the ultimate saving of time in the course of a dayl by the easy manipulation of this `press buck, in the manner indicated, will be very considerable.

The table D is supported in any well known manner, but preferably upon an angled iron frameA, such as isV shown, and it in turn supports. the press buck and the bracket for the rocking arm, aswill be hereinafter more particularly set forth. The bracket, which is designated by the letter E, is bolted `to the table and has'one arm eX- tending beyond and slightly above the rear end of" the table, as shown, and upon this arm is pivoted the rocking arm B; and said brackety is further made in the form` of a clamp'to embrace that edge of the table and` has its lower branch extended underneathl the table, to a1 ointslightly beyondthecen`- ter, so astoza ordi a support fromwhichlto hang several parts of the operatin'g'mechanism, as will be setforth.` 8 illustrate the construction of thisy bracket and means of attachingit to the table,`and

Fi Us. 1,2, and` latter to projecting lugs from the rocking arm B. In this machine, the power for applying the iron is very great, and, therefore, the movable joints through which this power is applied to the iron must be of unusual Substance, and, accordingly, I have devised special means to reinforce these joints without` adding materially to the weight of metal. By referring to Figs. l, 2 and 4 of the drawings, and especially to Fig. 4, it will be seen that at each joint of the rocker arm and on one of the sections there is provided a reinforcing lug 7c which is cast with the steel of the arm and curved on one face to rest against and snugly fit and turn upon the projecting lugs of the rocking arm and the middle arm, respectively, which projecting lugs are the bearings for the pivots and are rounded at the point upon which each lug bears. In short, the reinforcing lugs are concaved upon their faces which bear against the convex surface of the supporting lugs. A similar reinforcing lug 761 is provided on the arm at the point where the iron is pivotally connected thereto and which cooperates with the projecting portion of the pivot of the iron. It will be, therefore, observed that when power is applied to the rocking arm by any suitable means, and consequently the upper end of such arm is thrust forward and downward, these reinforcing lugs act as abutmentsto prevent the slipping of the pivot lugs so as to strain them or fracture them, which otherwise has been found in practice to result after the bearings of these lugs are worn, and permit certain movement on the pivots. This is especially necessary in a construction like the present one where a toggle lever is employed to apply the power, for, as is well known, a toggle lever is one of the most powerful mechanical instruments to apply power. And it must be understood that when the iron is upon the press buck, and is thus supported, the thrust of the operating mechanism is upon these joints or pivots between such iron and the rocker arm, and at this time these reinforcing lugs come into play most advantageously. The lower end of the rocker arm is secured by a pivot to the outer end of a short link of the toggle lever, the other link of which lever is pivoted at its outer end to the center post I-I, the latter being provided with a forked end for the purpose. The short link of the toggle lever is designated by I and the long link by I', and the inner ends of these two links are pivotally joined by a short shaft which extends through them and is also extended through the two upright bearing lugs m of the evener link K.

It will be observed, by inspecting Figs. 2 and 7, that the shorter link I of the toggle has a yoked end which connects it to the rocker arm while the longer link I of the toggle lever, is connected by a plane end to a yoke end of the center post, but this long arm of the toggle lever has in its turn a yoke at its inner or central end which incloses a plane inner end of the shorter link ofthe toggle, and thus the two fill the space between the vertical lugs m, m, of the evener link K. This evener K has centrally on its under side a depending lug n forming a bearing for the pivot which joins it to the yoked upper end of the draw bar L, and the lower end of which draw bar is threaded and passes through the main operating bar M, which, in this instance, is shown as a treadle bar, but, of course, may be operated by any suitable power, if desired. On the under side of this operating bar there is formed a semi-circular recess, as is best shown in Fig. 9 of the drawing, and in this recess is placed a semi-sphere N, through which the draw bar also passes and on the under iiat side of which rests the nut which holds' said draw bar in place and adjusts it. There may be also provided an additional nut as a lock nut, as shown. The upper side of the operating bar is cutaway angularly to permit movement of the bar on the draw rod. The evener link has hooked to each end of the same a spring O and the upper ends of these two springs are secured to the spring holder P, which in turn is adjustably supported from thebracket on the under side of the table by boss bolts r, 1, which pass through this spring holder and are secured to it by nuts arranged on the under side to engage such bolts. The tension or pull of the springs is adjusted by these nuts and boss bolts with the consequent action of holding up the iron at its proper normal position above the press buck and also holding the operating lever in its normal and proper position against the cross-bar of the frame. It is evident that if the springs became slack, and there was no means of adjustin them, the evener link would drop, as woiidd also the draw bar and the operating bar, which would cause the toggle levers t0 be straightened and the iron to approach too closely to the press buck, thus preventing the manipulation of the garment or goods to be pressed. Again, the movement of the operating lever may be variedby means of the nuts on the lower threaded end of the draw bar, which likewise effects a similar and additional adjustment of the position of the iron and of the several parts connecting it with the operating bar.

From the foregoing, it will be understood that the adjustment of the springs 0 upon the bolts fr', fr, will adjust the iron to the desiredvposition above the press buck, so that the goods being pressed may be manipulated by the operator properly and conveniently, and will at the same time hold the operating arm at its proper position for a state of rest. The adjustment of the draw bar through thefoperating arm will cause the springs to act in a particularly quick and easy manner, thus giving the desired tension to such springs and returning the parts to the proper position. It will also be seen that the co-action of the toggle levers and springs in applying the iron 'to the press buck avoids the jolt or jar which would re.-

sult injuriously to the operator when the iron contacted with the press buck through the means of a more positive movement, and

r at the same time any desired and necessary pressure may be given through the medium of this powerful mechanism now employed. What I claim and desire to secure y Letters Patent is,-

l. In a machine for pressing clothes the Y combination with the iron andv mechanism for operating the same, including a toggle lever, alink 1n which the arms of the toggle are pivoted at their inner ends and providing also a point of connection for the operating lever and for a pair of springs,

' springs secured to such link and supported from the frame, and means for adjusting such 4springs.
