UNITED STATES PATENT OFFICE ROBERT N. WEST, OF MAPLEWOOD, NEW JERSEY MACHINE FOB PRESSING FABRICS Application filed March 4, 1931. Serial No. 520,011.

- This invention relates to a combined press buck has a saddle 9 cast integral therewith and reciprocatory ironer, particularly adaptwhich is bolted to a corresponding saddle 10 ed for use in laundries and garment pressing of a weight member 12 so as to tightly emestablishments and has for its principal obbrace a sleeve member loosely mounted on the jects the provision of a compact and inexpenbuck supporting shaft 11 interconnecting the IS sive machine wherein the work is preferably opposing spiders and centrally positioned held in a horizontal plane throughout the thereon between the opposing collars that ironing operation and preferably a relative splined or otherwise rigidgy secured to said reciprocatory motion is provided between the shaft whereby said buck an oscillate freeheated chest and the buck, either when em- 1y on said shafts 11 and is continually main- 60 ploying the machine as a press or as a reciptained in a horizontal position during the rorocatony ironer, besides other advantages tation of the spiders. hereinafter set forth. Inthe'accompanying At the top of the machine is a heated chest drawings, in which I have illustrated a pre- 13, which has hollow guard members 13 soferred embodiment of my improved mechacured thereto, the same being spaced from 08 nism, and projecting across the ends of said chest Figure 1 is a vertical section, partly in eleand serving to prevent contact between the vation of such mechanism; hands or arms of an operator and the heated Fig. 2 is a front elevation of the same chest during the operation of the machine-,be-

2o mechanism; sides also serving to protect the face and body 7 Fig. 3 is a detail elevation partly in secof the operator from heat radiated from said tion of a modified form of counter balanced chest. The chest is provided with terminal buck; extensions or lugs 14 which are apertured to Fig. 4 is an end elevation, partly in section, receive piston rods 15 that are carried by pisof a still further modification, wherein means tons reciprocating within air or steam cylinare provided for transversely reciprocating ders 16, the latter having ports 17 and 18 for the heated chest during the pressing of the the alternate admission 0 fluid effecting the work, the chest being shown elevated; and vertical reciprocation of said piston rods.

Between said tion and in contact with a buck, the arms are 1. end plates is a rotary buck-supporting memmoved to an intermediate position between ber, the same comprising opposing spiders 3 said nuts, so that the chest rests by gravity 40 which are keyed to a shaft 4 that is mounted upon a buck and is not forcibly held thereon at its respective ends 'in bearin s in said by the upper nuts a. Said chest, if steam frames 1. An index plate 5 is ri-gi 1y secured heated, is rovided with an inlet and outlet to one end of said shaft 4, the same being conduit. 0 or the introduction of and withapertured at intervals and spring-pressed indrawal of steam from said chest in the well dex pins 6 are adapted to project into aperknown manner, although obviously an electures -7, spaced at 90 intervals around said trically heated chest may be employed, if deindex late, whereby the difi'erent positions sired. i

Each plished manually by means of handles (1 proof the fluid pressure medium from the pressure elevating cylinders 16.

In the construction shown in Fig. 3, the enlarged balancing weights 12, corresponding generally to the weights shown in Figs. 1 and i 2, are employed, said weights having down- 8. Such movement is positively 8.0001111 wardly projecting terminal lugs m that have flat bearing surfaces, which while preferably of the same thickness as the thickness of the weight from which they project, may obviously be greatly reduced in width since they are adapted to rest directly on the shaft 4 when each buck rides-into its uppermost position under the chest 13 and thereby the pressure imparted by the steam chest, when resting on such buck, is imparted directly to and borne in the first instance by said. shaft 4, thus relieving the shafts 11 from excessive central stresses. Obviously, however, as each buck leaves its uppermost position and commences to rotate between the framesl, the In :17 slide off and out of engagement with the shaft 4 and will not re-engage the same until such buck has .again attained its uppermost position beneath said chest 13.

In the construction shown in Figs. 4 and 5, I have provided means for causing a slight reciprocatory movement of the chest across the buck in a direction parallel to the axis of the shafts 11, while the chest is in contact with the work carried by the bucks, and thereby an extremely smooth sheen or finish is imparted to such work similar ,to that obtained when ironing with friction ironers or by hand. This latter construction is essentially the same as that shown in Figs. 1 and 2, except that the lugs 14: are provided with slots 6, which admit of the slight transverse movement of the chest with respect to the bucks plished by means of impulses imparted to the opposite ends f of said chest by'the'piston rods '20 that are carried by pistons within fluid pressure cylinders 21 which are rigidly mounted on the vertical piston rods 15. As shown, when one of said piston rods 20 is projected to the limit of its stroke, the other is retracted. Preferably the piston rods 20 are continuously operated in opposite directions during the ironing operation, irrespective of whether the heated chest is in an elevated or lowered position, as thereby the possible displacement of the work carried by the bucks 8, as might otherwise occur, due to excessive frictional engagement of the chest and buck, were the chest to be first lowered into contact with the work prior to the commencement of the transverse reciprocation of the chest, is avoided. In order to interconnect the piston rods 15 so as to maintain the same in parallelism, I provide a stay bar 22 which is secured at its opposite ends to the top ends of said piston rods 15. Said fluid pressure cylinders 21 which are well known equipment for supplying fluid pressure for various purposes, are provided with outlet ports gin the manner well known for the admission and escape of fluid during the respective strokes of the iston. s
