A TTORNEYS Patented Apr. 5, 1932 UNITED STATES PATENT OFFICE EMIL A. WINNEWISSER, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK REVERSIBLE PRESSING ELEMENT FOR PRESSING MACHINES Application filed May 22,

This invention relates to pressing machines as garment and laundry presses, and has for its object, a machine having one of its pressing elements provided with pressing faces of different character on opposite sides thereof and reversible to bring either face in cooperative relation with the other pressing element.

It further has for its object, a simple and eflicient construction by which a gaseous fluid as steam or air, or both, may be selectively projected through or from either of the pressing faces of the reversible element with the control means therefor so that the fluid can be passed only through the pressing face in operative position when the operator is standing in his usual or proper position in front of the machine.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are fragmentary front and side elevations of a machine embodying my invention.

Figures 3 and 4 are respectively vertical, cross and longitudinal sectional views through the reversible pressing element.

Figure 5 is a plan view on a reduced scale of the pressing head.

Figure 6 is an enlarged detail view of one of the steam control valves.

Figure 7 is an enlarged fragmentary view of the means for locking the reversible element in either of its operative positions.

Figure 8 is a side elevation on a reduced scale of a complete pressing machine.

The invention comprises in a pressing machine, a reversible pressing element having pressing faces of different character on opposite sides thereof and reversible to bring either face into position opposed to the other element.

In the illustrated embodiment of the invention, the pressing elements are arranged one above the other and the upper pressing element or head 1 is reversible and also movable 1929. Serial No. 365,182.

toward and from the lower element or buck 2.

The buck 2 is supported in the usual manner on the frame 8 and the head 1 is shown as carried by the usual frame or yoke lever 47 pivoted between its ends at 5 in the rear of the as actuated bya cylinder 7 having a piston.

therein, the rod 8 of which is connected by motion transmitting parts to the rear arm of the yoke lever. The motion transmitting parts here shown are an angle lever 9 and link 10. the press is opened when the pressure in the cylinder is released by countersprings 11. The flow of motive fluid, as air, to and from the cylinder, is controlled by suitable valves operated by a push button 12 to close the press and by a release lever 13 to open the press. The actuating means form no part of this invention.

The head 1 is provided with a rough ironing face 14; on one side thereof to give one are complementally concave. Also, the buck is provided with the usual pad 16.

The head 1 is pivotally mounted on its support or yoke lever 011 an axis extending lengthwise thereof between its front and rear edges, that is, transversely of the ma chine. The head is shown as formed with trunnions 17, 17 at its ends journalled in bearings 18 in the arms of the yoke lever 4. Obviously, thehead 1 can be reversed or somer-saulted about its axis to bring either face 14, 15 opposed to the buck 2.

The head 1 is provided with handles 19, 20 on opposite edges to facilitate the reversing. The head is held in either of its adjusted positions by impositive locking means as spring pressed balls or poppets 21 located in sockets 22 in the yoke arms and held in the sockets by plugs 23. The balls press or snap into shallow sockets 24 in the head. The poppets are located at the ends of the arms of the yoke lever 4 in front of The piston is single acting and.

dividual thereto and formed ma transverse strip or bar 33 in the chamber and intersecting the bar 30. The steam is supplied to the passages 31, 32 from the chamber 25,

, and the supply controlled by slide valves 36 and 37, respectively, which are formed with. passages 34 or 35 therein and operated by handles 38 and 39 respectively. The passage 34 and 35 communicates with the chamber 25 and with the passages 31 and 32 respectively through passages 42, 43. The valves 36, 37 and the valve handles 38, 39 are located at the opposite front and rear sides or edges of the head 1.

, The steam is conducted to the chamber 25 from a supply pipe 44 through the trunnion 17 which is hollow, out through the other trunnion 17 back to the source of supply or boiler. The outlettrunnion is provided with a coupling having four branch pipes 45 running part way round the top and bottom walls of the chamber 25, it being un- V ders tood that either of the walls forms the top or bottom of the chamber, depending upon which face 14 or 15 is opposed to the buck. The pipes 45 are open at their ends so that water or condensation is carried out 7 with the steam.

In operation, when the work is to have a rough finish, or the nap of the goods is to be 7 raised, the head is positioned with therough face 14 downward; this brings to the front of the head the passage 34 in handle 38 con- 7 trolling the flow of steam through the valve 36, passage 31, conduit 26 andjet openings 28. When the rough face is down and the handle 38 is in front and the other handle 39 isat the rear of the head where it can not be conveniently operated.

The rough face 14 is usually provided. :with a fine wire mesh screen, not before specifically referred to.

\Vhen a shiny or smooth ironing finish is desired, the operator takes hold of the handle 19, now at the front of the machine and starts to reverse or somer-sault the head and completes the reversing action withthe handle 20 when it comes within reach. When the, smooth face 15 is down or opposed to the buck, the work can be steamed by operating the valve handle 39 which is now at the front of the machine, so that steam passes from the chamber 25, through passage 42,

passage 35 in valve 37, passage 32, conduit 27 and jet openings 29.

WVhat I claim is:
