GARMENT SLEEVE IRONER Filed NOV. 5, 1938 Patented Nov. 21,1939 n WGABMENT SLEEVE mom John H. Leef, Minneapolis, Minn. Appuuon November s, 193s.. semi No. 23am z clam. (ci. zza-v3) l My presentinvention relates to improvements onI ironing machines of the type employed for ironing the tubular leg and sleeve portions of garments; and is in the nature of an improvement on or modification of the ironing machines disclosed and claimed in prior Patents 1,937,656 and 2,022,210; the former of which was issued jointly to myself and George H. Leef on December 5, 1933 and the latter of which was issued jointly to myself and said George H. Leef on November 26, 1935. Generally stated, the invention consists of the novel devices, combination of devices and arrangement of parts hereinafter described and dened' in the claims. f

In the said prior patents and in my present improved machine, there is provided a relatively ilxed and a relatively movable boot, the movable boot being connected to the ilxed boot by an interposed link. In the prior machines the means for moving the movable boot toward and from the xed boot was a device or devices operating directly on the movable boot but not operating through the link, In these prior arrangements the means forpresslng the movable boot toward the xed boot are to some extent interfered with and prevents the free oscillation of the movable boot on the upper end of the interposed connecting link. In my present machine this objection or feature is eliminated by applying the boot operating action directly to the interposed link, thereby leaving the movable boot perfectly free to oscillate on its pivotal connection with the link and to adapt itself to the outline or divergence of the garment leg, sleeve or other tubular article telescoped over the boots to be ironed thereby.

The commercial form of this machine is illustrated in the accompanying drawings wherein like. characters indicate like parts throughout the several n views. 1

Referring to the drawings: Fig. 1 is a perspective with some parts broken away and some parts sectional showing the improved machine;

Fig. 2 is a section taken through. the relative iixed and movable boots on the vertical axes thereof, some of the cooperating parts being broken away;

Fig. 3 is a perspective showing in detail an actuating foot pedal anda portion of the machine frame; and

Fig. 4 is a section taken approximately on the line 4-4 of Fig. 3.

Mounted on a common supporting table which consists of a topl and a frame-like leg structure v9, are pairs of cooperating hollow pressing boots.

movable boot I0. A leaf-like link II is, at its. lower end, pivotally connected at I2 to the base or lower portion yof the fixed boot 9. and at its upper endis connected at I9 to the intermediate portion of the movable boot I0. The boots 9 andIIl on their abutting or adjacent faces are recessed respectively at 9a and Illa to clear the link II when the cooperating boots are forced together.

These hollow boots will be supplied with steam through suitable delivery pipes Il and exhaust pipes I5, the arrangement of which need not be considered here further than to state that the connections to and from the movable boot will be flexible or such as not to. interfere with the free movement of said movable boot.

In accordance with" this invention the link II is provided with a depending and extended portion, which together with the link..forms a sort a of bell-crank structure pivotally mounted at its elbow. This extension, as shown, is formed by a at bar I6 and a projecting arm I1. The bar I6 is rigidlysecured at its upper end to the lower part of the link II by riveting, soldering or otherwise; and at its lower end said bar is rigidly se.

between and secured to the lower portions of thel sides of the frame 8. The lower ends of the connecting rods are provided with forked heads'that embrace the ends of the arms of the pedal I9 3 and are connected thereto by pins 2I that work in longitudinal slots 22 in the arms of pedal I9.

` Each paix` of boots involves a xed boot 9 anda thereby. aiording a slip connection, the imporv tance of which will presently be noted. The uplock lug 21 that is engageable with alock detent or flange 28 on a ilxed portion of the frame 8. The/.foot pedal I9 has afoot plate 29 that is notched at 30 to allow the foot plate 29 of the lock dog to work therein. This foot plate 2B is narrower than the foot plate 29 so that it can be engaged and disengaged by the foot on the plate 29 simply by lateral movement of the foot.`

When the foot on the plate 2S is pressed downward, the movable boots will be pressed toward and against the cooperating fixed boots. In performing this operation the pivot pins 2| will slip downward and backward in the slots 22 as far as they will go, thus causingthe two movable boots to be pressed closely against the cooperating boots. When this operation is performed while the lock dog 25 is released,'the latter will engage the detent 28 and lock the boots together as indicated.

To unlock the movable boots for separation from the cooperating fixed boots, it is only necessary to press the foot on the plate 26 of the lock dog, thereby releasing said dog from the detent 28. When this is done, the movable boots, under ,the action of gravity, will move away from the cooperating fixed boots, The extent that the movable boots thus move away from the fixed boots will depend on the: size and form o f the garment leg or the like that is telescoped over the cooperating boots; and in this action it is important to note that the movable boots pivot freely on the pivots I3 so as to adapt themselves to the shape and divergence of the article being from the cooperating fixed boots due to the fact.

that when one of the iixedl boots has engaged and adapted itself to the particular garment leg or the like, the pivot pin 2l, at the lower end of the connecting rod I8 can slip outwardly and upwardly in the slot I22. 'I'his permits the movement of the one movable boot away from its cooperating flxed boot to be interrupted before the other movable boot has completed its movement away from 'its cooperating fixed boot. 'I'he movement of the movable boots away from the fixed boots under the action of gravity when the lock dog is released is, of course, due to the location of pivots I2 forward of the centers of -gravity of the movable boots.

Adjustments of the pivot pins 23 at the upper ends of the connecting rods 'I8 not only permits variation in the throw of the arms l1 but permits ,independent adjustments of the two arms and,

hence, of the movements of the movable boots away from the fixed boots.

From the foregoing it will be understood that the device described is capable of modicatlons Within the scope of the invention herein disclosed and claimed.

What I claim is: I

1. In a device of the kind described, a supporting frame, a pair of fixed boots mounted on said frame, relatively movable boots cooperating with said fixed boots, links independently pivoted to p said xed boots-at the lower ends and independently pivoted to said movable boots at their upper ends, said links having laterally projecting arms, a foot pedal pivotally mounted on said supporting frame,r and connecting rods independently connecting said foot pedal to the arms of said links,\and-in which structure the lower ends of said 'connecting rodsA are independently connected to said foot pedal by slot and pin slip acting connections that operate positively to force the re spective movable boots toward the fixed boots but slip to permit diierential movements of the two movable boots away from their cooperating xed boots.

2. In a device of the kind described, a supporting frame, a pair of flxecl boots mounted on said frame, relatively movable boots cooperating with said xed boots, links independently pivoted to said xed boots at their lower ends andindependf ently pivoted to said movable boots at their upper ends, said links having laterally projecting arms, a foot pedal pivotally mounted on said supporting frame, and push linkage independently connecting said foot pedal to the arms of said pivoted links, said push linkage involving independent connecting rods each pivotally anchored to and interlocked with the common foot pedal at its lower end and pivotally anchored to and interlocked with an opposite of said arms at its upper end, the linkagebetween said foot pedal and each of said arms involving limited slack motion connections, whereby the movable boots will be simultaneously moved toward their respective fixed boots under lifting pressure exerted on the pedal but will be free for limited differential movement away from their respective fixed boots when the pedal is relieved of lifting pressure.
