'TRUSSING-MACHINEL SPEGIFICATIQNforming part of Letters Patent No. 699,121, dated April 29, 1902.

v Application filed October 28, 1901. Serial No. 80 305. (EomodelJ To all whomz't may concern:

Be it known that I, LOUIsD. VOGEL, a citi- Zen of the United States, residing atOrnaha, in the county of Douglas" and State of Nebraska, have invented anew and useful Truss ing-Machine,of which the following is a specification.

My invention is an improved trussing-ma chine for use in the manufacture of tubs and other similar, articles; and it consists in the peculiar wconstruction-and corhbination of devices hereinafter fully set forthand claimed.

In the accompanying drawings, Figure 1 is a side elevation of a trussing-machine embodying my improvements. Fig. 2 is partly a front elevation of the same and partly a' vertical sectional view taken on a plane at right angles to that of Fig. 1. Fig. 3 is a top plan view of the same, -partly in section one. plane below the plunger and abovethe forms on the form-carrier. Fig.4 is a vertical longitudinal central sectienal view of the same, taken on a plane at right angles to that "of Fig. 2. Figs. 5 and. 6 are detail sectional views of one of the expansibleplungers.

On opposite sides of a'ba'sel are a pair of vertical brackets2,iwhich supports -p1ate 3,;

that bears on theirluppe'r sidesl' Braees. rare secured to the inner sides of thesaidbrackets and to the upper s'ide'of the'base 1.- 'fThe said brackets are provided with bearings for' a shaft 6 and for a power-shaft}, which is disposed to one side of theshaft 6L Thez lat ter has spur-wheels 8 secured on its ends, and

the powe :shaft has pinions 9, which engage said spur-wheels? A circular revoluble table 12,which carries a plurality of trussing-forms 13, is mounted on the upper end of a shaft 14, which revolves, in bearings in the base 1 and in theplateY The trussing-forms are disposed equidistaut apart; and thetab1e'12'is' previded in its peripherywith stop-notches 16, which correspond in number with the trussin'g-form's and are disposed inline radiallywith the centers thereof. A's'top 17 is ..provided to engage the stop-notches "successively to arrest "the "rota- "tion of the table and lock the same in position, and the said stop is provided with a suitable pedal 18. As here shown, the upper portion of the stop projects through and operates in a slotted opening -19, with which the plate?) is provided .on its rear side. It will be observed by reference to Figs. 1 and 3 of :the drawings that'fthe revoluble table 12 extends beyond the front side of the plate 3.

. Two pairs of vertically-disposed parallel guide-rods 2O hav'e'their lower portions disposedand securedin openings in the sides of the base 1' and plate 3. The, said guide-rods extend upwardly above the table 12 a suit- ,able distance, and their upper ends are connected together we cross plate or beam 21. The'satne is'secured to the upper end of the guide-rod byn'uts 22 and is provided at its ceu'terwith a vertical bearing 23, above which 'is' an oil-cup 24. "{Slide-yokes 25 operate vertically on the respective pairs of guide-rods 20, and'a crosshead 26 is operated by the said slide-yoke's. Thelatter are provided on their outer. sides with trunnions 27. The gear-wheels 8 have crank-pins 28, which are radially adjustable ;therein, and pitmen 29 connect the said trunnions of the slide-yokes toTthe said crank-piiisof the gear-wheels 8. In the form of my invention here shown each pitrnan is composed. of .a pair of heads 30, which areresp'ectively clamped on and form .bearingsfor one of the trunnions 27 and one of the crank-pins 2 8, androds 31, which connect the said heads together. I The-sections of the respective heads of the pitm'en are clamped together by'nuts 32,which are-screwed on the i newt Itwill he understoodfrom the foregoing that when the shaft 6 is in rotation reciprocating verticalmovement will bezimparted to the cross-head 26. The endsof the latter engage notch es. 3 3 ,in the innerisidesof the slideyokes. The'said notchesare of greater vertical extentthan the thickness of the. ends of the said cross-head, and thereby lostmotion is provided between the cross head and the slide-yokes; the latter at each limit. of :their stroke moving a slight distance independently of the cross-head while the crank-pins 28am passing the dead-centers of thewheels 8.

A vertically-disposed.plunger 'rod 34operates in the bearing-23 of the cross-plate 21 and passes through a central opening in the cross-head 26. The said plunger-rod has a collar 35 at a suitable distance from its lower end, which collar is adapted to be engaged by the upper side of the cross-head on the upstrokes of the latter, so that said plunger-rod will be raised by the said cross-head when the latter is moving upwardly. A cap-plate 36 is secured under the central portion of the cross-head by bolts 37. Cushions 38, which may be made of rubber or other suitable material, are interposed between the cross-head and the cap-plate, so that the latter is yieldably connected to the former, and the said cap-plate is provided on its lower side with an annular flange 39 of suitable diameter, the inner side of which is inclined upwardly inwardly, as at 40. The diameter of the capplate within its flange 39 corresponds with the exterior diameter of the upper edge of the tubs or other articles to be trussed by the machine. On the lower portion of the plunger-rod are apair of plunger-heads 41 42, the latter being lowermost and of less diameter than the former. The said plunger-heads are a suitable distance apart and are free to play vertically on the plunger-rod. The latter has a stop-collar 43 to limit the downward play of the plunger-head 41 and a stop-collar 44 to limit the downward movement of the plunger-head 42. It will be understood that the plunger-heads will be of suitable size to enable them to enter a tub or other article in one of the forms 13 on the downstroke of the cross-head.

Prior to setting the machine in motion to cause the cross-head to descend the table 12 will be locked in position to dispose a tub or other article in one of the forms 13 in position directly under the plunger-rod and the plunger-heads carried thereby. On the downstroke of the cross-head the plunger-heads enter the said tub or other article, expand the staves thereof within the hoops or rings of the tub,and move the staves downwardly to tighten the hoops or rings thereon. As the plunger-heads descend initially in the tub their descent is arrested by their engagement with the inner sides of the staves thereof, and the cross-head continuing to descend the flange 39 of the cap-plate 36 rides over the upper ends of the staves, the beveled inner side of said flange drawing the upper ends of said staves inwardly, evening the same and preventing the staves from splitting. Said cap-plate as it completes its descent with the cross-head levels the upper ends of the staves, as will be understood. Owing to the lost motion which is provided between the crosshead and the slide-yokes the cap-plate is caused to dwell on the upper side of the tub for an instant prior to the ensuing ascent of the cross-head.

I provide a vertically-movable arm 45 to release the plunger-heads and raise them in the trussed tub prior to the ascent of the crosshead. This plunger-arm is operated by an eccentric 46, which is fast on the shaft 6.

The plunger-heads are expansible radially,

being provided with radially-movable members 47, which are pressed outwardly by springs 48. This construction of the plunger-heads enables them to be raised and released from the trussed tub by the upward movement of the arm 45.

The revoluble table 12 has a gear 49 on its lower side, which is engaged by a pinion 50 on a shaft 51. A sprocket-wheel 52 on said shaft 51 is connected by an endless sprocketchain 53 to a sprocket-wheel 54 on a shaft 55, that is also provided with a sprocket-wheel 56. Said wheel 56 is connected by an endless sprocketchain 57 to a sprocket-wheel 58, which is loose on the shaft7 and has a clutch member 59. A power-pulley 60, driven by a suitable belt from a counter-shaft, isloose and capable of longitudinal motion on the shaft 7 and provided with a clutch member 59 to engage said clutch member59, and thereby impart rotary motion to the wheel 58, and hence to the table 12. Said sleeve has at its opposite side a clutch member 61, adapted, in coaction with a clutch member 61 on said shaft '7, to impart rotary motion to the latter, and hence to the shaft 6, when said sleeve is unclutched from the said sprocket-wheel 58. Hence rotary motion may be alternately imparted to the table and to the shaft 6, the latter, as before described, operating the plunger-heads when the table is at rest. An arm 62, which is connected to said sleeve and to the arm 18, automatically shifts the powerpulley into engagement with the wheel 58 to rotate the table 12 when the stop 17 is disengaged from the latter and reversely shifts said power-pulley into engagement with the shaft 7 when said step is in looking engage ment with the said table.
