pUNITED STATES PATENT OFFICE Tomas e. JASPER, or BROOKLYN, NEW YORK rmissme Maonms machines, and more particularly to themeans for taking upthe'stress and strains developed in such machines durlng the various pressing Owing to the enormous strains developed in pressing machines during the pressing pheavy and to add heavy castings to brace and rigidly tie the supporting frame of such machines together while in operation. This excessive weight adds considerably to the cost of the machines as Well as to the difiiculty in the handling during transportation and installation of such machines. Likewise it limits the number of machines that can be safely installed upon afloor and despite the precautions taken, the breakage of pressing machine parts is not eliminated.

The main object of my invention is to overcome the above undesirable features inherent in the present day garment pressing machines.

Another object of my invention is to provide a resilient bed plate that will take up the 1 strains and stresses developed during the pressing operation and at the same time act as a support for various parts of the machine and effectively tie together the balance of the supporting structure of such machine, thus permitting the various parts of the machine to be made substantially light in Weight.

Another object is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to de scribe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests Application filed February a, 1932. Serial No. 591,277.

a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint. 55 The inventive idea involved is capable of receiving a variety of mechanical expressions, eratlons 1t has been the custom to make the -various parts of such machinesabnormally one of which, for the purpose of illustration, is shown in the accompanying drawings, in which 7 Figure 1 is a side View of a pressing machine partly in section in which one form of my invention is shown, and

Figure 2 is a top plan view thereof, with parts broken away for the sake of clearness. 35 Referring now to the drawings in detail, 5 indicates the lower or supporting framework of a pressing machine to the top of which is secured'by means of bolts 6, a resilient bed plate of comparatively light weight. A table top 8 usually made of wood overlies the said plate and is suitably secured to the frame.

Secured to the rear of the plate 7 by means of bolts 10 is a bracket 11 provided with ears 12 in which there is. suitably .j'ournalled a shaft 13 upon which there. is pivotally mounted ajlever 14; to the lower arm 15 of which there. is connected a connecting rod 16 in operative engagementiwith a depressible foot lever 17 pivoted at 18, said lever being maintainedcin. upper position by a spring 19. The lever 14: isprovided at its upper end with an arm20 terminating in upper and lower bearings 21 and 22' respectively. Between the said bearing there is swingingly supported on a rod 23, a. bracket24 having a slidewa-y 25 in which there is slidably supported a bar 26.

The said slidebar terminates at its forward end in a hub 27, through which passes a stud 28 which pivotal ly supports a pressing iron 29' adapted to be pressed against a pressing buckBO, secured by means of bolts 81 tothe plate 7 the base of said buck passing through an opening in thetable 8.

= By depressingthe foot lever 17 against the tension of the spring 19 the lever 14 is rocked about its pivot 13 causing the iron 29 to be brought. down against the buck 30. It will be; seen from the drawings that due to the connections '14:, 24a and 26 a comparatively large leverage is produced, especially so if the bar 26 is extended so as to bring the iron into pressing position at either of the ends 80a or 3012 of the buck. This large leverage greatly multiplies the pressure exerted by the foot lever 17 and the iron 29 exerts an enormous pressure against the buck which in the present day machine transfers the said pressure to the supporting structures as well as to the various other parts of the mechanism connected torthe pressing iron; Due to this-- pressure and the lack of resiliency of the prestil i and act as a spring bumper.

that will effectively take up ent day pressing machines, one or more parts of said machines becomes impaired after some use, and eventually snap or break during a pressing operation.

In my improved machine, however, this is impossible, as any pressure-exerted on the buck will cause the resilient plate 7 to give or'spring and cause a breathing or heaving action of the said plate and carry with it the bracket 12 as ,well as the connections 14, V 24 and 26, thus relieving the said'parts of any excess strain or pressure. I

It is to be understood that the table top 8 is not securely fastened down to either the plate 7 or the frame 5,, but merely lies on the late and held against lateral movement only hy any suitable means. The said table is only utilized to support garments to be pressed and may entirely be dispensed with if desired. The buck 30 however as previously stated is fastened to the plate 7 which is preferably thin and resilient, consequently when pressure is exerted on the buck at either end 30a or 30?) thereof, a'great strain is put on the plate which strain is not'transferred to the frame or any rigid'part connecting the said frame, but is taken up by the resiliency of the plate causing same to warp temporarily From the foregoing it will be seen that I have provided means in a pressing machine any undue stresses and strains from the supporting structure as well as the operating parts of the machine and prevent the said parts from becoming impaired and eventually breaking when the machine is being used. 7

It will further be seen that due to thismeans the operating parts, as well as the supporting structure, may be made comparatively light in weight thus eliminating the disadvantages and objectionable features of they present day pressing machines.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a pressing machine, a supporting frame, and a resilient pressing-apparatus' ver operatively connected to the said plate, pressure applying means connected to one end of the said lever, and a movable pressing iron carried by the other end of the said lever and adapted to be brought into pressing engagement with the buck.

3. In a pressing machine, a supporting frame, a resilient bed plate connected thereto, and pressing apparatus carried by the said plate and adapted to move therewith when pressure is applied thereto.

In a pressing machine, a supporting frame, a resilient bed plate connected thereto, a pressing buck at one end of the said plate, a bracket secured to the said plate at theend opposite to the pressing buck, a lever pivotally supported on the said bracket, a

movable pressing iron pivotally carried by the said lever at one end thereof, the said iron belng adapted to be brought into pressing contact with the buck, and pressure applying means connected to the other end of the said lever.

In testimony whereof I hereunto afiix my signature.
