,- improved garment pressing machine of small compact size adapted to be hand or foot pressure by improved power means.

Another principle object of the invention is to produce a pressing machine having correspondingly equal sized pressing jaw members possessing a novel movement to provide extended visibility of the work and easy access thereto without at the same time raislngv the press head high of the buck, the object being to combine this feature with operating means, power driven if desired, all parts of which are locatedwithin the frame of the press to avoid the ordinary present dayrearwardly extending horizontal and weighted press lever which usually vrequires considerable ioor space to swing up and down to the rear of the press frame. To this end one of my improvements relates to a vertically disposed press lever, the movement of whichdoes not extend beyond the boundary of the presslng machine frame,

and my machine therefore requires no more space than the frame itself requires; and the novelty of this feature. rests in pa'rt in the combination thereof with improved operating mechanism. 1 p

Another object of the invention is to produce an improved pedal and toggle of less number parts than ordinarily employed, and to use in connection therewith motor'means for producingdnal pressure; and a feature of 1 my invention is the combination of a diaphragm with a lever to impose high pressure beween the press jaws. n

My invention further relates to .improvements over the pressing machine invention described in my application Serial Number 687 `765, filed January 22, 1924. v

The accompanylng drawings illustrate a preferred embodiment of the invention and it is understood how changes in construction and .mode of operation may be made without departing from the scope and principle of the invention.

Figure 1 shows a side view of the pressing to permit the old style lever machine with the press head open. The dotted outline indicates closed position of the press dotted lines, and the motor means, being the improved diaphragm pressure developing element., is shown at rest just prior to expansion to apply final pressure to the press jaws. This view also illustrates a toggle and pedal element of composite structure which is characterized in that an extension of one 'of the toggle links forms the pedal.

Figure 2 shows a side view of the lower portion of the press with the motor means and toggle in .high pressure position with the pedal 30 also omitted for clearness.

Figure 3 shows a cross sectional view as developed along the line 3-3 of Figure 2, and the pedal 30 is left off in this view as well..

Referring further to the drawings for a detailed description of the invention, there is shown a pressing machine frame 10 having the usual table 11 and back plate 12 to vprevent the garment from falling olf of the table to the rear; and a legged type frame is shown but it is to be understood that a pedestal frame may be employed if desired. The frame supports a press buck 13, and both pressing jaws, the buck 13 and head' 15,' may be heated by suitable means Such as steam or electricity. The heating means, however, is not illustrated because my. invention particularly relates toan improved construction in press operating mechanism intended to reduce the size of pressing machines in general and simplify their construction.

The pressing head 15 is carried on the upper end of a -vertically disposed ress lever composed of an upper yoke or arc 16 and a lower arm 17 4integral therewith. The lever is pivoted at 18` on the press frame 10 and hooks over or curves around the plate 12 and reaches forwardly to carry the press head 15 back and forth up and down on the buck; and

jaws but with the pedal 30 omittedin' surface ofthe buck to extended visibility to provide an unobstructed view of the work. furthermore in my pressing machine it is not necessary to lift the head 15 so high as with the usual style of pressing machines for the reason that the said head 1s moved rearwardl while in present day pressing machines the head must necessarily undergo long movement to gain visibility and access to the work which leads into complicated operating mechanism for performing such high head lift. Instead of operating my press jaws by simple angular movement, which after all s till leaves the large size press head poised directly over the buck, I combine rectilinear motion therewith which imparts to the head a rearward throwback action simultaneously with the angular rising movement; and to accomplish the results named it is noted that the lever fulcrilm point 18 is placed below the meeting or pressing jaw plane and to the rear of the longitudinal axis of the pressing jaws. In carrying out'the foregoing mode of operation I am enabled to remove the usual rearwardly projecting lever arm with exposed counteralance weight and install it inside the press frame together with a new toggle pedal locking means, the separate elements of which do not wholly constitute my invention, for that more particularly is in thescombination.

rIhe lower arm 17 of the press lever projects downwardly in a substantially vertical direction and is adapted to swing in and out of the frame as shown in the two positions in Figure 1. An improved feature of my invention is the compact design of the operating mechanism whereby the press lever 17 is caused to remain within the bounds of the frame and not permitted to swing beyond the limits thereof for the reason that to do so would take up space and be wasteful of Hoor area such as now is so common of pressing machines on the market. My machine is intended to be operated by hand or by pedal for closing the head thereof, and immediately after the pressing members have made contact, the power means is manually turned on or automatically turned on, as the case may be, for the purpose of applying inal pressure by power means to save unnecessary labor on the part of the operator. Preferably the head of the press is closed by hand, and for this purpose a handle 19 is provided on` the head by which the operator pulls the head forwardly and downwardly, but it will be shown how a foot pedal may be used in this connection as well.

A counterbalance weight acts against the press lever to equalize the weight of the head 15, and to this end a bell crank 21 is pivoted at 22 on the frame and on one arm thereof a weight 23 is ixed while the other arm thereof is pivotally connected by a link 24 to the press lever 17 rI`he weight and appliedleverage of the counterbalance member 23 acts to poise the head 15 in such a manner that an operator may readil pull the head downwardly and forwardly y hand in contact with the buck 13, but theweight 23 may if desired overbalance the head to automatically open the press at the end of the pressing period.

A toggle locking and pedal closing mechanism consists of a link 26 pivotally connected to the press lever at 27 and pivotally connectedv at 29 to a companion link 28; and the link 28 has the other end thereof pivotally mounted upon a power lever as will be described. A removable pedal 30 has the inner end 31 bolted onto the link 26 and reach- Y es around the link 28 and projects forwardl of the frame where it is 1n convenient position for the operator to place his foot thereon to facilitate the straightening of the toggle 26-28. TheA pedal 30 may of course be integrally formed with the link 26, but in the present disclosure I have illustrated 4it as being detachable from the toggle link 26 for the purpose of removing the pedal entirely' from the pressing machine thereby permitting the press to be closed by hand powe'rn only. 'Ihe pedal 30 is only shown in up position, the press being open, and is omitted from other views for clearness.

A bell crank having lever arms 32 and 33 is pivoted at 34 to the frame l0. The arm 32 is made considerably longer than the depending arm 33 for the purpose of producing leverage. The lower end of the short arm 33 pivotally supports the lower end of the short toggle link 28, and the bell crank 33 thereforeV acts as a support for one end of the toggle 26-28. A pivot pin 35 pivotally connects the toggle link 28 to the bell crank arm 33 and acts more or less as a fixed support against which the toggle 26--28 pushes or rIhe pivot pin 35 also carries a kick-off ped l al comprising a foot piece 37 with a rear arm 38 carrying al lug 39 reaching underneath the pivot pin 29 connecting together the two toggle links 26 and 28. The kickof pedal'normally rests against a frame stop 40 and stands in position ready to thrust upwardly against the toggleto break its locked position to open the press. The operator is required to exert only slight pressure on the kick-off pedal 27 to break the toggle causing the head 15 to rise.

The long lever arm 32 of the power bell crank reaches rearwardly and is acted on by motor means for the purpose of producing final pressure; and in this instance I have ysa produced an improvement in power presses, for rather than use an electric motor, or a steam or air cylinder, I employ an improved diaphragm or fluid pressure motor for moving the arm 32 through a short distance under is securedV to the frame 10 by a bracket 43.

-The bellows or diaphragm 48 has its lower end anchored to a head 44. The head is lprovided with a locking lug which rests in the housing 42, and a steam or air pipe connection 46 is established with the head 44 to supply steam or air to the motor means from a pipe 47. The diaphragm 48 has its upper end anchored between a concave head 49 and a screwed on -cover plate 50. The part 50 may project over the rimof the housing 42 if desired to completely enclose and rotect the bellows element 48. A post 51 1s made integral with the bellows head 49-50 and reaches up to engage the endof the lever 32. The bellows unit 48 stretches out under fiuid pressure admitted thereinto to swing the longer arm 32 upwardly which correspondingly swings the short bell crank arm 33 rearwardly to produce a thrust through the over-straightened toggle linkage 26-28. The steam-pipe 47 is equipped with a valve 52 which is providedwith an exhaust port 53. A valve control rod 54 connects with the stem ofl the Valve 52 and reaches forwardly of the frame where the front end of this rod is equipped with a double acting valve control member having opposite foot pieces 55 and 56. When the operator depresses the pedal end 55, the fluid pressure is exhausted from the diaphragm 48 out through the exhaust port 53; and when the operator de- A presses the other end 56 of the foot pedal,

steam or fluid pressure is quickly admitted from the pipe 47 into the pipe connection 46 to expand the bellows and produce high pressure between the pressing jaws as explained.

In the operation of the machine, the oper- I ator spreads the work upon the buck 13 and draws the head closed by using the handle 19 or by depressing the pedal 30, or by using both such means if desired. By the time the head 15 reaches engagement with the work, the toggle 26--28 has reached straight line position and has sli htly overstraightened itself to produce a loc ed condition such that the said toggle 26-28 stands'out in a slightly overstraightened condition .under the strain and thrust imposed therethrough by the bell crank arm 32 when the high pressure motor means acts.

The operator next depresses the pedal 56 which oscillates the rod 54 to open the valve 52 thereby admitting fluid pressure under the motor head 49 of the unit whereupon the diaphragm instantly expands upwardly to that position shown in Figure 2, the result of which is to impose extremely high pressure between the pressing jaws. After the pressing period has been prolonged a suitable tlme, the operator depresses the other side or end 55 of the motor control pedal to cause the pressure to discharge fr'om the unit 48 thereby permitting the bell crank arm 32 to gravitate downwardly which quickly and noiselessly removes high pressure from the head, whereupon the operator depresses the kick-off pedal 37 which breaks the toggle 26-28 upwardly thereby permitting the head 15 to quickly rise as it is lifted by the counter weight 23. v

My improved motor means saves the exense of manufacturing the piston and cylv lnder elements necessar1ly employed in fluid pressure motors heretofore used. Furthermore its use eliminates the leakage of water and oil which always occurs around the ordinary fluid pressure motor such as an engine or a pump. Very little expansion or movement is required of the motor 48 for the reason that the pressing jaws are brought into close Contactin engagement before the diahragm acts. inal pressure is imposed by introducing a strain throughout the operating mechanism which is carried out without .apparent motion of parts. Theonly appreciable moving operating parts is the short upward stroke of the outer arm 32 and the bell crank which travels a very short distance due to "the fact that the head 15 has already engaged the work and buck prior to starting the motor means. Furthermore, my improved power press and its motor means is very economical in fluid pressure such as steam for the reason that the head 49 is concaved into the element 48 which fills up the entire space ordinarily present in the bellows and thereby requiring a relatively small amount of fluid pressure to operate the motor means.
