application filed August 27, 1920. Serial Nd. 406,362.

.termed mang1es, and has tor its object the production. olf suoli a device, simple and effective in its operation. To this end it con sists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

ln the drawlngs, wherein like reterence characters indicate like or corresponding parts,

Figure 1 is a front View of my improved device;

Figure 2 is an end view ot the same taken from the right;

Figure 3 is a transverse vertical section taken substantially on line 3-3 et Figure 1;

Figure L1- is partial end view taken from the right illustrating a dierent position oit the parts;

Figure 5 is ;a partial end sectional View substantially the same Figure 3, showing the parts in a ditlerent position;

Figure 6 is a section taken substantially on line 6-6 of Figure 2f. and

Figure 'l' is a detail view.

ln the drawings, 1 represents a suitable support which niay be a table, or more conveniently a receptacle provided with doors 2 2 or equivalent construction as indicated in Figure 1. Upon the upper surface of the supportor table arranged my improved device, suitably supported by end pieces and Ll. llear one side or edge is provided a shoe 5 extending ported on a pipe 6, which serves to conduct a heating medium to the shoe in the usual manner. rThis medium may be steam in large machines. or preferably in smaller machines it is suitably constructed to heat the slice by a medium such as gas, electricity or gasoline.

il. rotatable cylinder 7 which may loe suitably padded is arranged substantially parsubstantially the jtullj l length of the table, preferably pivotally supallel to the shoe 5 and is mounted in such manner that the position of the cylinder in relation to the shoe may be controlled and regulated as desired. ln the preferred form shown, the cylinder' is mounted upon a suitable shaft 8 which has its ends positioned in slots 9 formed in the supports El and yl. Each end-of the shaft is also mounted in a trame 10 and retained in relative position therein by springs 11 arranged to resiliently press the shaft in a direction toward the shoe. The frames 1() are mounted upon the supports $5 and il so as to be slid-able relative thereto, and means are provided to torce the frames toward the shoe as desired. vrflic various elements are preferably duplicated at the ends with/the exception of the driving means which need be provided at one end only.

1n the preferred form shown, tilt revers 12-14 are pivotally supported on the supports 3 and 4 as at 13 having the end 1.11: bent upward and provided with ratchet teeth 15. A. cooperating pawl 16 isv pivotally supported on the support as at 17 so that as the part 14 is raised, the pawl will engage therewith and hold it in the elevated position. A link 1S is pivotally engaged with the part. 12 and extended downward, and is attached to a treadle 19 which constitutes a lever pivotedbetween its ends, so that upon depressing the outer end ot' the lever 19, the link 1S will be lifted, elevating the part 14. A spring 2i) connected to the part 12 and to some fixed part of the device. as at 21, serves to auton'iatically draw the lever 12-14 back to its normal position when the pawl 16 is released. Any preferred means may be employed to conveniently release the pawl. As shown, a board 22 extending parallel to and preferably about level with the top of the cylinder serves the double purpose of a sup-- port in passing and guiding the fabric upon the cylinder and as a releasing lever. As shown, the board may be pivotally supported to the frame as at 23 with a depending finger 24 extending beneath the -free end of the pawl 16. A slight lift of the lree edge of the board 22 will therefore disconnect the paWl from the ratchets 15, which will permit the lever 12k-14; to fall to its normal position. The spring 25 or other preferred means may be employed to resiliently maintain the paw] in lproper operative position. As an alten.

native construction, which, however7 may oe used in connection vwith the construction just described, the pavvl may be provided with an extendingv arni 26 which may be operated from the outside of the device and serve to release the pavfl Without disturbing the fable 22. Also as an alternative construolion, which, may, however. be used in connectioi'i With the treadle lever 19. a hand lever 2T. conveniently arranged. ma;7 be pivotally connected as at 28, engaging' Jdie link le? at 29. The operation of thislever will likewise serve to elevate the tilt, lever 12-14 as described.

The frames @wat their outer or free ends operatively engage or Contact with the le- Ver 12- lll, so chat as the latter is lifted in the manuel' described. lle shaft S will be forced Vforward in the slots l). carrjv'inn the cylinder 7 into proximity to or contact with the curvedface'o the shoe 5. This contact is resiliently maintained bv means of the springs l1. Upon the outer end of he shalt.

8.,.p`referably exterior to he support 3. is rigidly mounted a cog or `frear wheel 3l), clearly shown in VFigures 2 and 2. Nor molly, that is, when the lever l2-llis at the downward limit offis movement. the cog-Wheel 3() is disengaged. bul as il is forced forward with `the sha lit in the manner described, it automatically engages Wih a 'cooperating gear wheel B1 which may be driven in any preferred manner. )is shown. the gear wheell is connecred lo and i'orins a part of a gear wheel 32 meshing` with the Worin tgear 33 driven by a motor 8l.

lhile this is a very convenien ineans oi" driving the same. any other preferred means may be employed for that purpose.

:is thus described. it will be apparen thatA upon elevating the tilt-lever lil-ll. the cylinder 7 Will he caused to approach ixhe shoe, and the gear Wheel 3() lo engage he cooperating tCrear wheel 31 and be driven thereby. The cylinder is resilientlv forced agains' the shoe which is heated stared. and the fabric supporled upon lie shell' 22 and eX- tended to the cylinder between rile latter, and the shoe will be resilienllv forced against the smooth surface or' the latter as the cylinder rotates. rl`he pressure ma)v be regulated as desired bv the loot lever 19. The cylinder maav be instantly released b v disconnecting the pawl from the ratchet teeth l5 of the lever I4- in. either ol the ways described.

ln some cases it may be desired to control the operation of the device by the 'Foot lever 19 or hand lever QT withouithe use of the pawl 16. To provide For this. l. have arranged a latch 35 (Figures Il and 5) pro vided with a hooked end 3G which may be pressed downward to engage die end of the paWl 16 and hold the same -out ol operaiion. The pawl may be released by depressinghe eme Al'ree end of ihr later. as clearlyv shown. rl'hen lhe pavvl is thus held oui or operation. the cvlinder is held in position to smooth or iron the gfoi'ids by means of the 'foot or hand leve' alone. lf the former is used, it will leave both hands free o Inanipulae the goods, and die Inos'v delicaie manipulation is thus made possible. Upon releasing' the cylinder and its gear Wheel 30. the cylinder is easil)T roaed in lhe ren verse direction for ehe removal of the goods. The usual ball bearing or other anti-frie'ion devices n av be employed throng-honiy with rood ellecr.

ln soine instances it .mayv be desired lo move the shoe 5 bachY from iis normal posil'ion. lnasniuch as it is pivoally supporh ed upon lle pipe (j. this inaj' be readilj,T accomplished as shonn in dotted lines in Fig ure handles 3T upon he face of the shoe or equivalent means being` provided for core venience.

A simple larchor connecing member o an)7 desired construction inav be enr,"

lo hold the shoe in relative posiion for op f eration. The siniple means shown. more clearl'vv illusi'rated in VFigure l'. consists olf a huinb screw 3E? passing through the end supports and with its end engaging an apen ture in the end of lhc shoe Retracingr the screw will release the shoe and permii'` it lo be moved backward as indica el.

The til lever 'l2-li is pref,rablyduplicated at each end 'to secure reliable operation. and the 'arious levers and parls described preferably extend across lie Jfull length of the face oli the machine convenience in ruieratingr. so 'that at ivliarever poiul llie operator niajv eniplov these de vices.`thc operation will he elleced at each end ol rbc cylinde as desrrilied.
