DHV/D GoLoBL-RG FirToR/VIEY of the work-blank the machine is suitably secured to the top of 1 a table T and comprises a supporting frame I on which is mounted a base'mernber II which, Y
more particularly shown in Figs. 2 and 5, lisr provided with a relatively largel opening I2 of suitable size and shape to receive and have loosely fitted thereinto an upwardly movable pressing or ironing plate I3 which is preferablyv of similar shape and is adapted to be suitably heated asl hereinafter more particularly specied. Saidi opening I2 and plate I3 in the instant embodiiment of this invention are rectangular in shape and are of sufficient size or area to enable the ironing or pressing of work-blanks such as shown inFigs. and 11.
Mounted in the machine in superposed and spaced relationship to thebase member II is a top member I5, a horizontally disposed space I6 being thus provided between the members III and I5, and the top member I5 is provided with a blank-receiving opening II (see Figs. 2 1and 3) registering vertically with the opening I2 and the pressing or ironing plate I3 but of smaller size. The opening I1 is preferably formed `in the general shape of a work-blank I4 such as illustrated in Fig. 10 but is contracted and somewhat smaller than theblank I4 in order to enable the proper positioningwithin the said opening of the blank I4 with the edge IIIa thereof (see Fig. 1l) in raised or upright positions, which "edges are' subsequently to be folded as hereinafter specied. `This opening I1 is adapted to receive and perkmitthe downward and upward movement therethrough in substantially flat or'horizontal posiltion of a thin clamping plate I9 adapted in de- 'pressed position within the machine to clamp the work-piece or blank `AIII against the pressing or ironing plate I3. The clamping plate I8 is also of a shape'and size substantially corresponding 'with' the outline of the folded work-piece as shown inFig. 1l and with the outline of said opening jI'I and is the member about which-the edgefolds in the work-blank are made. Said plate I8 closely fits said opening I'I, space preferably being left at its edges only for the thickness of the fabric of the work-blank.
As shown, the clamp plate I8 is suitably mountedon and movable with a pivoted or hinged manually depressible and spring-raised-operating lever I9 hinged as shown at I9a at the rear kside, of the machine and adapted to be elevated orl raised and to benormally held in elevated position by a spiral spring stretched between a fixed point 22 on the frame of the machine and arr-'adjustable hook 2| to enableV regulation of the tension of the spring 20. In Fig. 1, the operating lever is shown in elevated position and in Fig. 2 it is shown in depressed position, 'a handle or knob I9b being provided at the end of the lever for manual engagement by an operator for movement of the lever from raised position of Fig. l to the lowered position of Fig. 2. The clamping plate I8 per se has .its central portion unitarily mounted on and fastened to a mounting or carrier member Ifl with its edges free. I8b-I8b, andsaid` plate I8 together with said vmounting screws or studs 23,- 23f yare -at their -lower endsA secured tosaid plate ZIB and to its mounting or carrier member I8L1 and blocks I8b,
, I 8b, and these studs are then passed through registering holes in a lever spacing block I9c and in said lever I9, said slight shifting relative movement being obtained by making the holes in the Said carrier plate has spacer blocks lever and its spacing block slightly larger in diameter than the, shanks of the studs 23, 23 and said resilient holding being accomplished by positioning spiral expansion spring 23h-23" on said studs or screws 23-23 between heads 23a-23e thereof and the upper surface of the lever I9. The raising movement of the lever I9 `by the spring 2li4 is, as shown, cushioned by 'fastening an outwardly curved spring 24 on the frame of the machine and providing an adjustable stop member 25 on said lever I9 which is positioned on an extension I9d of saidv lever and ,extends at the opposite side of the hinge pintle I9=1 so as to engage' said spring 24 at the end of the upward movement lof the lever I9.
Edge-folding mechanism comprising flat plates 25, 25EL are s lidably mounted in the space I6 between the members II and I5 andabove the pressing or ironing plate I9 and these plates are adapted to slide above or overfthe edges ofthe clamping plate I8 to produce the edgefolds I4a in the blank I4 and to engage and vre'- leasably lock said clamping plate in'its depressed position. As illustrated, the sectional folderplate members v25--252L have overlapped sections adjacent to the ront'of the'machine and a pusher-plate 25 is so positioned in the space I6 at the front of the machine as to cause its rear edge to engage the folder-plate members 25, 25 'and move them into contracted positions to fold the edges of a blank and to move, as more particularly illustrated in full lines in Fig. 5 and in dotted lines in Fig. Bywhile its forward edge extends beyond the forward edge of the supporting frame I0 and is provided'at said forward edge with a downwardly extending flange 252L arranged inualignment and operative engagement with one end of an voperating lever element 2Gb pivoted'betwee'n itsendsA and having on its power arm a cam surface engageable by treadle-actuated operating vmechanism adapted to move this pusher-plate'26 inwardly' to force the plates 25, 25a'into fold-making and clamping plate engaging position andl this inward movement of the pusher-plate 26 by the lever 26b is arranged'in suitably timed relationship with theV dnvnward movement of 'a treadle-actuated ,operating` leverk for causing the upward movement of .y they presser plate :asv hereinafter more particularly'specified. f 'j' y In initial position ofthe plate lmembers 25, 25a, the edge-sash; 25e-25d andzse will be positioned in substantial yalignment withthe edges of the opening lI'I'and the overlapped sectionsA preferably comprise. transversely overlapping neck` portions of reduced thickness to provide thin slidably engaged neck flanges 25f--g25 as shown in Fig. 9, which t vwithin the space I6-and are movable therein Without binding,

The pressing and ironing plate I3 'is normally `held and supported on'Y the endsV ofadjustable studsor screws 32, 32 in a horizontal lposition and partially extending into theopening l2. A transverse beamz member 33` suitably connected to the baseimemberby spacers-34 and screws or studs' 35 supports-the screws132', 32. Said pres- 'sing' plate` I3 is forcibly moved orv pressed upwardly into ironing position by an operating lever-3|. This 1ever'3l ispreferably'mountedat the middle ofV the machine in alignment with the flange 26e-of thefpusherplate-and, as shown, is pivotally and adjustably mounted between its ends on a stud 3'6 having V mounted `thereon a spring 36 and washer 36b adapted normally to maintain said lever 3`=I in horizontal position,A and iid-provide a relatively shortA rearwardly extending" pressureapplying arm 3Ia` anda forwardly extending depressible power arm 3|b extending to` and beyond the front supporting members of themachine.

In the preferred embodiment of my, invention shown, the' current to the electrical heating elements is' capable* of being turned` on" and" olfand also suitably modified torregulate the heat by a conventional switch and regulating element S. Suitable stationary blank guiding strips y, y', g2 and g3 are positioned at the forward end and sides of the blank receiving opening and in parallel alignment with the edges thereof and a movable end strip g? is slidably and adjustably mounted onk the side strips g, g to enable adjustment of the length of the work-blank.
In operation, the heating switch and regulating element are iirst operated to heat the pressing plate, and assuming the yparts to be in the position illustrated in Fig. 1, the work-piece is properly positioned in the work receiving opening |1 and in relationship to the blank guiding strips g, Ag', g2, g3 and g4, the lever I9 is depressed by the hand of the operator to move the clamping plate into an initial lowered position to engage the work-piece, and while holding this lever and plate by hand, foot pressure by the operator on a conventional treadle (not shown) will through the chain 39 swing the combined lever and double-acting cam 38. Movement of this double-acting cam will in a single continuous movement but in proper successive sequence move the cam-lever to move the pusher-plate inwardly and also will depress the control lever 3| for the ironing plate. The movement of the pusherplate, in turn, causes the folding plates to move over the clamping plate and to fold the work- 1 piece. Depression of the lever 3| raises the ironing plate into tight ironing or pressing engagement with the Work-piece. Movement of said lever 3| is preferably guided in a slot IBC in an apron plate Illb at the front of the machine. During depression said lever 3| will thus engage the inclined slip-nose of the spring-actuated oscillating hook to oscillate the same on its pivot 4|a, and to move the integrally connected extension lever arm 42 against the action of the spring 431. Upon movement of the lever 3| below the slip-nose of the pivoted hook, the said spring 43b will press the hook into engagement with said lever 3| to releasably hold the same in its lowermost depressed position, with the ironing plate forced upwardly into tight ironing engagement with a work-piece beneath the clamping plate. Upon Vsuch engagement of the oscillating hook 4|, the
lclamping and ironing parts of the machine will be held in ironing position; manual pressure will `be removed from the treadle and the cam member 38 will be returned by springs 40 to the position shown in Fig. 1 to free the path of return movement of the lever 3|b when engagement thereof by said oscillating hook 4| is released. l
Such ironing usually requires a period of time, and during this time period the operator is free to proceed with other operations or with work on another machine if desired. When the pressing or ironing operation is completed, the operator merely depresses the knob 43 against the action of the spring 43b to release the oscillating hook from the control lever arm 3 |b of the ironing plate. Manual tension on the cable-acting cam l38 having been theretofore relieved, and
said cam having been automatically moved upwardly by the springs 46 out of the path of the lever 3|, the inner power-applying arm of said lever 3| will be moved downwardly by the spring 36a to release the pressure through the stud 31 against the plate I3, thus permitting the ironing plate to move downwardly away from the workblank. .The stress by the cam member 40 on the operating lever 26b of the pusher-plate having l been relieved by the upward' movement of the double-acting cam38, the spring 26x will move the pusher-plate 26 and its operating lever 26b to'their outwardly extended positions. The upward'movement of the lever 3.8C of the cam member 38 is limited by projection 44a on the xed forwardly projecting plate 44. The outward movement of the pusher-plate 26 having moved itsoperating lever 2,55b outwardly, the movement of these parts will be limited by a fixed pin 44b on said forwardly projecting plate 44. The edgefolding plates will simultaneously be moved to theirV extended positions by their operating springs 25g thus releasing the clamping plate I8 and permitting the lever I9 carrying said clamping plate i8 to be automatically raised into the normally inoperative position shown in Fig'. 1 by spring 20.
