PRESSINGi-MACHINE.

To all @kom 1f/may concern:

Be itlrnown that I, HARRYPRIGE, a subject oi'- the Czar of lRussia, and a resident of Bostonlyin the county of Suiolk and State of Massichusetts, have invented certain new and useful Improvements' in Pressing- Machines, ot which the following is a specification.

ThisY invention relates to improvements for use of tailors in pressing fabrics usually made-up into garments, the machine beingequipped with a press bed and with a pressing iron or tool similar'to an ordinary tailors goose, and with mechanism for supporting the iron in such manner that the tailor may move it freely about by the use ot' his hand and may exert downward pressure upon it bythe use of his foot.

The invention has for its object to provide improved means for supporting, guiding, and applying pressure to the movable iron. The invention consists in the improvements which I will `now proceed to describe and claim.

Fig. 18 represents a section -on line 18--18 of Fig. 1. l

The same reference characters indicate the same parts in all the figures. l

The supporting frame of my machine includes 'a base 12 and supporting legs 13`and 13a. The base 12 is provided with a guide 14 in which' an upright Spindle 15 is vertically movable Another guidelG is preferably attached to the supporting legs 13'* and is formed to receive and guide the lower end portion of the spindle 15. The upper end portion 15a of the spindle is reduced and screw-threaded, and with said reduced portion is engaged a stop nut 17 adapted to be adjusted vertically on the spindle extension'15a. l

18 represents a l vertically and rotate on the spindle 15. The upper end of the sleeve bears on` the stop nut 17. Y v

An upwardly pressing spring 19 bearing at its lower end on the base 12 and at its upper end on a collar 2O interposed between it and the sleeve 18, exert-s a continuous upward pressure on the sleeve and on the spindle 15, the spindle and sleeve being, therefore, normally supportedyieldingly in the raised posit-ion shown by'Fig. 1.

The sleeve 18 is provided With a teleleopic arm composed of an inner member 21 forned on or attached to the sleeve, and an outer member 22 which is slidable in the inner member 21 and is provided with means for .enga-ging a pressing iron or tailors goose 23. The collar 20, which is interposed bLet-ween the spring 19 and the sleeve 18, is adapted to slide vertically on the spindle 15, and is :termed as a ball race to support, a seriesl of aiiti-'trictioinll balls 24 interposed between it andthe sleeve 18, as shown,by Fig. l.` Rotation ot' the collar 20 is preferably prevented by a stop arm 25, Fig. 18-projeeting -between the brackets 13".

`The lower end portion of the spindle 15 isprovided with a seat for a rider on the. treadle lever hereinafter described, said seat being preferably formed by a circular roll 26 mounted to turn freely on a truunion 27vattael1ed to and projectingr laterally from the spindle 15. As shown by Fig. 4, the spindie is prmfidedwith two rolls 26, these being sleeve adapted to move ler;

soY

forming a two-part antifrictionallrider seat. 28 represents a` lever pivoted or fulcrumed at 29 above the rider seat to the supporting frame at one side of the spindle, said lever extending across the spindle and being provided at its opposite end with a foot rest 30 adapted to be depressed by an operator standing in, position to manipulate the iron 23. The lever 28 is provided with a rider 31 which is located below the fulrum 29 and bears upon the rider seat 26, the rider being preferably composed" of an anti-frictional roll having trunnions 32 which are journaled in bearings in the treadle 28, there being preferably tw.o of vthese rolls, as shown by Fig. 4, these constituting a two-partrider which is supported by and is movable upon the rider seat. i y

The spindle 15, normally held yieldingl in an elevated position by the spring 1 causes the rider seat 26 to exert a constant upward pressure against the rider 31 and'4 vated position shown by full lines in Fig. 1, the frame being provided with a stop 33 adapted to limit the upward movement of the lever and therefore the upward movement of the spindle and the arm carrying- Athe pressingA iron 23. The iron is thus yieldingly supported above a press bed 34 which. is supported, as hereinafter described, by

the base 12, the height of the iron above the press bed being determined by the stop 33,' s t The arrangement of the lever 28, its fulcrum 29, and rider` 3l relatively to the spindle and the rider seat 26 is such that when the lever.is ,raised the rider vbears on the rider #seat at one side of the highest part of latter, as shown by full lines inkFig. 1, and

when thelever is depressed the-rider moves in a downwardly inclined path.v When. the operator `depresses the treadle 30, `the rider is caused t'o move downwardly over the rider seat and to depress the latter until the rider reaches the highest part ofthe rider seat,` the, spindle 15 and the iron 23 being thus depressed and the ironcaused to beartirmly on the fabric. placed on the press bed'g34. lt will 'be seen by reference to Fi s. 1 'and 6 that wlieuthelever'28 reaches t evext'reme of its downward movement, the point of contact between the rider 31 and the seat 26 is transferred. from one side of the seatto kthe opposite kside sol thatwhe'n the lever `is fullydepressedLthenpward pressure of the seat againsttheI rider tends vto hold'the levery and the iron 23 depressed, so that the operator may removefhis f (ipti from the trea- -dle without releasnfgthe iron. Pressure of their-'on upon the abrio may thereforebe maiiitaineowi-thout tlie aid 'fthe operators foot. Then it is desired to release and raise the iron, the-operator may exert upward pressure on the treadle in any vsuitable Way until the rider has moved back over the seat sufficiently to permit the upward pressure of the spring 19 to raise the spindle, iron, and lever. I have here showna supplemental treadle lever 28a whereby the operator may press the lever 28 upwardly. The 'antifriction character of the rider and rider ets 13b. Said weight acts as an adjunct of' the spring 19 in exerting upward pressure on the spindle and the associatedparts yieldingly supported by the spring.

The spindle is prevented from rotatin inl its bearmgs by suitable means 'such asv s ots or openings 38 in the lower guide 16, the vertical sides of saidopenings bearing on the rolls forming the rider seat and actingv as guides'for said rolls and as sto s to pre-y vent rotary movement of the spindle.

The normal height of the iron 23 may be varied by adjustin the nut.l l'l' vertically and also,by' similar y adjustingthe stop 33 which limits the upward movement ofthe lever 28.

means of a horizontal elongate burner 39 (Figs. 11 and 12) which receives a mixture of air and gas, the gas being su plied .through anipple 40 connected by a exible tube 41-(Fig. 12) with a `source of gas supply, 'said nipple delivering a mixing chamber 42 having air inlets 43. The mixture of air and gas passes through a short tube 44 connecting the'mixing chamber with the burner 39. The bed 34 is preferably a Hat metal plate to the under' side of which the burner 39 is attached, as shown by Fig. 11, said late having a marginal flange or rim 34 o the form shown by Figs. 11 and 12, said rim forming portions of a combustion chamber under the press bed.

I prefer to secure the bed 34 to the frame on the machine in such manner that it can' be readilyremoved and also can be swung horizontally on one of its end portions. To this end I rovide the" supporting :trame with a'pair of c ampinO' jaws 45 and 46 which are pivoted at 47 to ih engaged with an arm 49 attached to the base 12.' The jaws 45 and 46 are provided 'with rearwardly extended inclined arms 50 beltween which is interposed a wedge block 51. Said'block is adjustable by means of a vscrew 52 to close the jaws upon the bed 34 or to release their pressure thereon.

The outer end portion' of the bed 34, or

t-he portion opposite that engaged by the the gas to e screw-threaded stud 48- The press bed 34 is preferabl heated byl jaws 45 and 46, is sustained b an adjustable support composed of a be piece `53 at tached to a bracket 54 on the base 12 and having ratchet teeth 55 on its upper side, a 5 block 56 bearing on the under side of the bed, a link 57 pivoted to the block 56 and bed piece 53, and a pawl 58 pivoted to the link and adapted to engage the ratchet. teeth 55 and support the block 56 at different heights. 'The block 56 is provided with an upwardly projecting tenon 59 (Fig. 14) which is adapted to enter the slot formed by the inner edges of longitudinal strips 60 on the flange of the bed 34, (the s ace between these strips forming an outlet or the products .of combustion from the combustion chamber formed by the .body portion and ange 34a of the .press bed) When it is desired to remove the press 'bed from the machine the jaws 45 and 46 are'separated to release their hold on the bed and the bed is lifted from the block 56. The described supports enable the bed to be held atany desired height above the base 12 and t-o be inclined, if desired, from a horizontal position.

The outer member 22 of the iron-carrying arm is provided with a socket 61 (Figs. 9 and 10) adapted to receive a spherical enlargement 62 on a shank 63 ailixed to the iron 28, the iron being thus adapted to oscillate on the center of the enlargement 62. A pin 64 retains the shank 63 in the socket. The iron is provided with a handle 65 by which it may be manipulated.

In practice, the lever 28 is provided with two side portions located at opposite sides of the spindle 15, as indicated by Figs. 4 and 5. In Figs. 4 and 5 I show the lower guide 16 provided with vertical ribs or guiding keys 66 which enter grooves formed for their reception in the lower'portion of the spindle 15 and prevent said spindle from rotating in its bearings.

Ittwill be seen that the elevation of the spindle 1.5 is limited by the abutment of the lever 28 against the stop 33. The stop nut 17, which is virtually a party of the spindle, does not limit the elevation of the spindle but enables the iron-earrying. arm to be adjusted vertically independently of the spindle. lt is obvious that any other suitable means may be substituted vfor the stop 33 for limiting the upward movement ot the spindle.
