IRA ANDREW POWELL, 0F ST. LOUIS, MISSOURI.

GASKET-MAKING MACHINE.

Application filed March 13, 1916.

T 0 all 'whom t may concern:

Be it known that l, IRA A. POWELL, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Grasket-h/laking` Machines, of which the following is a specification.

One of the principal objects of my invention is to provide an improved machine for making gaskets or washers, incorporating means for shaping the gaskets, stamping or compressing the same, and then re moving them from the die.

Another object of the invention is to provide a gasket making machine which will be extremely simple, durable, eflicient in operation, and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction1 combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which like characters of reference indicate like parts throughout the several figures, of which- Figure 1 represents a view in front elevation of a gasket machine constructed according to my invention. Fig. 2 represents a side elevational view thereof. Fig. 3 reprcsents'a view in section taken horizontally on the plane indicated by the line 3-3 of Fig. 1. Fig. 4 represents a fragmentary view partially in section, showing the position of the parts after the gasket has been shaped on the die. Fig. 5 represents a view similar to Fig. 4, showing the position of the parts at the completion of the compressing operation.

Referring more particularly to the drawings, the machine includes a pair of spaced vertically extending parallel standards 5, which may be formed of lengths of I-beam, the standards being secured by means of angles 6 to the gtioor of the shop, and at their upper ends being connected together by means of plates 7. Secured by means of angle irons or brackets 8 to the uprights 5, is a horizontally arranged table or plate 9. lt is partly supported by means of the legs 10 secured at their upper ends to the table, and at their lower ends bolted or otherwise fastened to the Hoor. The table is provided with an opening 11, through which a die 12 carried on the upper end of a vertical shaft 13 is adapted to pass. This shaft 13'is'slidably and rotatably journaled Specification of Letters Patent.

in abearing 14 carried by the uprights 5 beneath table 10, and the shaft has a bevel gear 15 slidably keyed thereon, said gear being supported upon a cross piece 16 carried by the legs 10: A bearing 17 secured to the' cross piece, slidably receives the shaft 13. A, spring 18 interposed between the lower end of the shaft and the floor normally maintains the shaft at the upper end of its path of movement, so that the guide 12 will be positioned vabove the table 10.

A horizontally arranged main shaft 19 is journaled in bearings 20, between the uprights 5 near their upper ends, and is adapted to be coupled by means of a clutch 21 with a pulley 22 driven by means of a belt 23 from a suitable source of power. A pulley 24 operated from the pulley 22 drives belt 25, which in turn drives a pulley 26 carried on a shaft 27 which is journaled adjacent the lower `ends of the standards 5 in bearings 28. This shaft 27 carries a pinion 29 which meshes with the pinion 15, whereby the die 12 may be driven in a rotary manner. f

A crank arm 30 carried on the shaft 19 is connected by an adjustable rod 31, with a pin 32 carried byv a vertically arranged squared rod 33 which is guided for reciprocationin bearings 34 carried by the uprights 5. The adjustable rod 31 comprises segments connected by a turnbuckle 35 which may be operated `for drawing the seg ments toward each other, or for shifting` them apart. ln this manner, the path through which the pilot 36 carried at the lower end of rod 33 reciprocates, may be varied. The pilot 3G is circular, being arranged above the die v12, and is tapered at its lower end as at 3 7. A circular flange 38 is carried near the upper end of the pilot.

A stripper 39 in the nature of a plate having an opening therein through which the pilot 36 may project, and having upstanding arms 40 at its rear portion, which arms lie against the uprights 5, is provided. The arms 40 of the stripper have slots 41 cut therein, and bolts 42 carried one by each of the uprights 5 project through these slots and guide the stripper in its up and down movements. A lever 43 having a bifurcated inner end between the prongs of which a corrugated roller 44 is journaled, is pivoted as at 45 to the table or plate 9. The lever 43 may be moved in one direction or the other, for bringing said rollery 44 toward or away from the die 12. This die is circumpath of movement, for stripping the gasket from the pilot.

3. A gasket making machine, including a table, a die arranged above the table and adapted to be vertically reciprocated through an opening provided in the table, said opening being of a diameter substantially equal to the diameter of the die, means for compressing an unfinished gasket against the die whereby to impart the configuration of the die to the gasket, a pilot arranged above the die, said pilot being of a diameter substantially equal to the diameter of the die, means whereby the pilot may be vertically reciprocated for moving the die through the opening in the plate, resilient means for returning the die to its normal position, a stripper arranged between the die and pilot and having an opening through which the pilot is projected when moved downwardly, said pilot being provided with a flange for engaging the stripper whereby to move the latter downwardly with the pilot, and means for limiting the upward movement of the stripper prior to the arrival of the pilot at the upper end of its path of movement, whereby to strip the gasket from the pilot.

4. A gasket making machine including a table having an opening therein, a circumferentially corrugated cylindrical die arranged above the plate in alinement with the opening and adapted to be shifted downwardly through said opening, means for re turning the die to its normal position, means for rotating said die, a circumferentially corrugated vertically arranged roller adapted to be moved toward and away from the die for imparting the configuration of the die to an unfinished gasket arranged on the die, a pilot arranged above the die, means for reciprocating the pilot in a vertical path at will, for driving the die through the opening in the plate whereby to Compress the unfinished gasket against said plate, said pilot at its lowerpend being of a diameter substantially coincident with the diameter of the die whereby the pilot may advance through the gasket for imparting the proper internal diameter thereto, and means for stripping the gasket from the pilot as the latter moves upwardly.
