GARMENT OR IRONING PRESS Filed July 28, 1928 2 Sheets-Sheet 2 INVENTOR James arm/ad ledeller 1 ATTORNEY Patented Apr. 19, 1932 UNITED STATES PATENT OFFICE JAMES CAMROD LEDBETTER, OF NEW YORK, N. Y., ASSIGNOR TO THE PROSPERITY COMPANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK GARMENT OR IRONING PRESS Application filed July 28,

This invention relates to pressing machines and more particularly to garment presses and laundry or ironing presses.

An object of the invention is to produce a press having wide opening jaws, one of which has a compound motion including a laterally forward and backward motion and a vertical compressing action to produce jaw compression on the work between the jaws.

A further object is to produce a press having wide opening jaws, say of the type wherein the buck or lower pressing member or jaw is ordinarily stationary while the other pressing member, say the head or upper jaw is movable; and the jaw opening action is wide to afford a clear view of the buck so the work may be easily placed thereupon.

Though the invention is susceptible to being converted into many forms, the accompanying drawings show one example of the press serving to illustrate the principles involved and wherein:

Figure 1 is a view of the press in closed position with the jaws under compression; and Figure 2 is a side view of the press with the jaws in open position and ready to receive the Work.

In carrying out the purposes of this invention there is provided an upright swing link pivoted on its lower end in a frame under the jaws and attached at its upper end to the head jaw. In this way no counterbalance weights are employed. Improvements in operating means to produce jaw compression as well as regulating means to vary the jaw pressure forms a part of the invention.

Any suitable press frame 4 is employed which may carry one stationary jaw, as the buck 5, together with a table 6. A headsupporting arm or lever 7 is pivoted in the frame at 8 and any suitable means such as a spring 9 is arranged to normally urge upwardly the lever 7 so as to separate the jaws for release ofthe compression from the Work and followed by opening motion as will be explained.

A head or jaw support swing link 11 is pivoted at 12 on the arm 7 and extends rearwardly from the frame and extends vertically upwardly and then forwardly over the jaw 5 where the head support 11 forms a bracket to 1928. Serial No. 295,951.

mount a handle 13 by which the operator pulls capscrew or other means 16 is screw threaded intothe frame or into the upright llias the case may be. By properly adjusting the cap screw 16, the jaws 14 and 5 are caused to properly align one over the other so that the head comes to rest in its forwardly limited position in registration with the buck 5. The adjustable means 16 therefore provides a stop for the heacLcarrying swing link 11 and Which is at the same time adjustable.

Operator-actuated means are provided to produce jaw compression after closing the press. An example of this operating means is shown in the form of a toggle or pedal mechanism wherein-a pedal 17 is integrally formed with an arm 18 to make a bellcrank 1718 which may for convenience be pivoted at 12. The bell crank arm 18 in fact comprises one link of the toggle 1819, the two links of which are. pivoted together at 20 and the upper end of the togglebeing pivoted at 21. When the pedal 17 is down, the toggle 1819 rests in straight line position or its center 20 is in slightly over-straightenedpositionto, lock the jaws together under compression. When the pedal 17 e is up the toggle 1819 is broken to relieve the jaw compression and to permit jaw separation which re-. sults when the head 14 is swung rearwardly to expose the buck. A stop is provided to limit the forward straightening actionof the toggle 18-19 and may comprise ahand adjustment screw 19a'mounted in a bracket 4a carried on the toggle. i

The upper end of the toggle 18-19 is piv-r otally swungon the frame 4 and therefore has a normally stationary pivotal support while the lower end of the toggle swings at 12 on the support arm 7 and thus has a movable support. Toggle adjustment means is provided by which the upper end of the toggle 19 is adjustably carried on the frame and when the machine is under pressure.

pression regulating means movable parts remain clean.

' the frame at 30 and its inner end ing means comprising is moved'vertically in relation to the frame 4, the result of which is to similarly adjust the upright 11 by which jaw compression is regulated to a greater or less degree.

An example of the adjustment means comprises a worm wheel 23 engaging a worm 24: fixed to a shaft. The shaft 25 is journalled in the frame 1 and has a hand wheel 26 on the outer end thereof under the table6 convenient to the-reach worm wheel 23 is fixed to the shaft 21 and a cam 27 is fixed to the shaft 21. The cam 27 is journalled in a bearing formed in the upper end of the toggle 19. In otherwords the toggle swings from the cam 27. The operator turns the hand wheel 26 to rotate the cam 27 to adjustably move the upper end of the toggle in vertical relation to the frame 4. Since the upper end of the toggle swingson the cam 27 it follows that by moving the cam 27 upwardly thru the agency of the hand wheel 26, the lower pivot 12 1S correspondingly elevated to provide more clearance and less pressure between the jaws 5 and 14. By rotating the cam 27 downwardly the opposite result is obtained and greater compression is produced;

The toggle pivot points 21 and 12 may be arranged vertically under the buck 5. If desired, the two pivot points 21' and 12 are disposed in vertical alignment in the plane of the mean longitudinally center of the jaws when closed or thus arranged in that relation to the stationary buck 5. The jaw com- 26-27 is mounted in the upper part of the frame under the table and hence high above the floor where, these The adjusting mechanism includes relatively few parts-and is simple in construction.

In operation, buck 5 and the operator forwardly, whereupon he depresses the pedal 17 which over straightens the toggle 18'19 thereby delivering a thrust on the lever arm 7 and consequently drawing downward on the upright head swing link 11 to produce jaw compression between the pressing members 14 and 15. r

A kickoff or release pedal29 is pivoted on the under edge of the compression pedal 17 pressing the kickoff 29, the pedal 17 is raised and-hence-the toggle 18-19 is'broken rearwardly and the spring 9 lifts up the operatthe several parts and hence. lifts the head so the latter may fall backto open position.

1 The press opening and closing motion is by lateral action, while compression and re lease thereof is by vertical action. f Thehead therefore swings directly back out of the way rather than by a risingaction. The maof the operator. The
