(Cl. 38-v-36) 11 Claims.

This invention relates to a press for laundry and dry cleaning establishments.

The chief object of this invention is to provide a-press with mechanism whereby the cooperating pressing parts are positionable in pressing relation and in released relation by hand operation and more especially the locking and pressure is capable of application in one operation.

,A press of this character requires no supplei mentary source of power, such as air or steam pressure nor does it require another source of power such as a motor, thereby reducing installation, maintenance and operation costs.

The chief feature of the invention consists in providing a press with mechanism of relatively simple character which can be readily operable by hand and which can be adjusted for any desired pressure application and which has the operating characteristics and all the advantages before mentioned.

Another feature of the invention consists in a multiple lever arrangement having a toggle type connection therebetween.

Other objects and features of the invention will appear more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a side elevational view of a press embodying the invention, the parts being shown in the pressing position.

Fig. 2 is a top plan View of the lever operating parts of the invention.

Figure 3 is a partial side elevational View on a slightly reduced scale, and illustrating the relation of the parts when the press is in open position.

In the drawings I0 indicates a foot structure which is provided with a counterbalance spring anchorage II and suitably secured to the central portion of said foot structure and extending upwardly therefrom is a pedestal I2 of any suitable outline and the same supports at its upper end a base portion I3 which is provided with a rearwardly and upwardly and outwardly inclined frame structure I4 provided with spaced portions Ida, each of which includes a pair of openings I5 Iand I6, these openings in the two spaced portions I 4a being aligned and constituting pivot bearings for levers hereinafter to be described.

Suitably secured as at I'I is a buck support I8 of any conventional character, which in turn supports a buck i9. Suitably supported by mechanism hereinafter to be described and in super-.

posed relation relative to the buck I9 is ya cooperating pressing head 2D carried 'by a support portion, in turn carried by the main lever, to which reference will be had shortly.

In order to protect as well as support the garments being handled by the press, there is provided an apron structure 22 of any suitable conformation and the same terminates in a forwardly and downwardly directed marginal portion 22a for operator protection. The apron 22 may be suitably secured as at 23 either to the buck structure I3 or directly to the base I3, as desired, or to the frame structure I4, whichever is the most convenient, or to all of same, as desired.

The buck and head may have suitable connections to air and steam pressure, if the press is to be an all purpose press, as is well understood in the industry. rIhe invention, however, is not directed to the aforesaid but is directed to the operating mechanism whereby the head is caused to move into position immediately adjacent the buck and is then caused to exert pressure on the garment between the buck and the head and is held in that position until it is released and upon release and following initiatory return movement, manually effected, the head structure may be raised to what may be termed the open position through the counterbalancing arrangement, hereinafter t0 be described, or by any other suitable means.

Referring more especially to the upper portion of Fig. 1 and to Fig. 2, it will be noted that the head supporting lever includes near the right hand end-see Fig. 2-a pair of spaced arm portions E. These arm portions include a pair of aligned socket type pivots 25 adjacent the end. At the end there is provided a pair of aligned sockets 26. The same is adapted to seat the opposite ends of a shaft 21 `and each end of the shaft is drilled and tapped as at 28 to receive the threaded portion of a bolt 29, the head of which bears on a retaining washer 3l). In this manner the shaft 28 is suitably secured at each end between the two spaced portions 24 of the head supporting lever and at one end thereof.

A suitable shaft means 3 I-see Fig. 2-is seated in the sockets 25 and is mounted in the openings I5 of the frame structure I4. It will thus be notedsee Fig. l-that the extreme end of the portions 24 of the head supporting lever project rearwardly beyond the frame structure I4.

A spring 32 has its lower end, which is in the form of a partial loop, secured or anchored in the opening II in the foot structure. The upper end of this spring is suitably secured to an anchor member, see Fig. 1, 33 apertured as at 34 to threadedly receive the threaded stem of the elongated bolt having the head portion 36. A locking nut 31 cooperating with the spring anchor member 33 adjusts the effective length of the counterbalancing spring arrangement and also adjusts the force thereof, the greater the length of the tension spring per se the greater being the counterbalancing force exerted on the head supporting lever. The shaft 21 previously mentioned, is suitably apertured as at 38 and the portion 35 of the elongated bolt structure extends through this opening and the head portion 36 of said bolt bears on the shaft. A washer, if desired, may be interposed between the bolt head and the shaft.

The two spaced portions 24 of the head supporting lever are joined or suitably connected together as at 39 and projecting oppositely therefrom are two arm portions 40, and the same form a suitable anchorage for connecting the head support 2| to the head operating lever, as shown in Fig. 2. The central portion 39 of the head supporting lever is suitably apertured and medianly as at 4| and this aperture is threaded.

Another lever structure, angular in elevation, see Fig. 1, is also provided and it includes two side Wall portions 42, see Fig. 2, from which at the vertex of the angularity projects two apertured bosses 43 apertured as at 44, see Fig. 1. portion of the lever at the right hand end is indicated by the numeral 45 and connects the two side portions 42 and this portion is suitably apertured as at 46, see Fig. 1. The portion 45 is nestable between the two arm portions 24. The opposite end of this pressure adjusting toggle lever is indicated by the numeral 41 and connects the other ends of the side members 42 together. Provided therein is an opening 48.

A threaded stem 49-see Fig. l-mounts at its upper end, a handwheel 50 and is threaded in the opening 4| in the head supporting lever. It projects through and beyond said lever and has its lower end extended through the opening 48 and on its lower end mounts a retaining member in jv the form of a nut 5|. l

Interposed between the portion 41 and the boss portion 4| and concentric with the member 49, is a spring 52, the force of which is adjusted by means of a collar 53 locked on said member 49 as at 54. The collar is threaded and can be readily raised and lowered when the locking member 54 is released. f

A hand lever, see Fig. 2, includes two side portions 55 which at their outer and forward end,

are apertured as at 56 and mounted therebetween is a handle portion 51 which is provided for operator engagement. The side portions are suitably connected intermediate their ends as at 53. The opposite ends of the side portions 55 are suitably connected together as at 59 and the same are apertured as at 6|] to receive a. shaft 6|. The shaft 6| has its ends seatable in the openings I6 in the frame structure I4. This constitutes the pivotal support for the hand lever. It will be noted -see Fig. l-that the side portions 55 extend upwardly and terminate in the connecting portion 59. f

Positioned slightly forwardly of said portion 59 and below the same, are two inwardly directed bosses 62 apertured as at 63. In eiect, therefore, the hand lever structure is T-shaped in elevation.

An open, rectangularly shaped link 64 is suitably connected as at 65 at its upper end to the bosses 62 and at its lower end as at 66 to the boss The body portions 43 of the toggle lever structure previously described. It will be noted that the toggle lever structure lies within the outline area of the opening in the head supporting lever and the handle lever lies within the outline area of the head operating lever. The frame lies within the same while the link lies Within the outline area of the hand lever, see Fig. 2.

The operation of the device is as follows: After the various lever structures are associated together as described, and the counterbalancing is adjusted, the toggle structure is adjusted by means of hand wheel 50 so that the desired pressure is effected between the buck and the head when the handle lever is in the position shown in Fig. 1. It will be noted this toggle structure does have a yielding connection by means of the spring 52. The pressing and holding position is the oncenter position of the toggle structure, described, and Fig. l illustrates the parts in that position. It might be slightly overcenter but this departure beyond center is very slight. When the desired pressing interval has elapsed, the operator lifts the hand lever which breaks the toggle joint, as it were, and the hand lever moves upwardly and rearwardly, and the head supporting lever also moves upwardly and rearwardly by means of its counterbalance and the toggle connection continues its collapsing movement. The range of angular travel is such, as the parts are herein illustrated, that the hand lever has greater angular movement than the head supporting lever and by reason of the adjustable toggle connection, any desired pressure within the range of the adjustment can be obtained between the head and buck.

The open work character of the handle lever permits the hand wheel 5i) to nest within the handle lever opening when the handle lever is positioned immediately adjacent the head supporting lever. The handle lever construction is apertured as at 10 and in said aperture may be suitably mounted -a cushion or bumper structure 1| so that the hand lever has cushion contact with the head supporting lever when the parts are in the pressing and holding position, as shown in Fig. 1. This cushion construction may be of any suitable character.

Mounted upon the inner face of each arm |4a is a bumper 8| for engagement .by shaft 21 upon movement of the head into open press position.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in char'- acter.
