My invention relates to a mufiler cup assembling machine and I, declare the following to be a full, clear, concise and eXact description thereof suflicient to enable anyone skilled 5 in the art` to which 1t appertains to make and w use'the same, referencebeing hadto'the accompanying drawings in whioh'like reference l characters refer to like* parts throughout the specification. i

The object of the invention is to provide a machine adapted to aid in assembling the cups of a muflier used Vin connection with the eXhaust gasesof an internalcombustion engine of` automobiles. In multlers of the cup type, theseveral cups fit together tightiy Vat theirI contacting edgesto aid inholding them togetherfl Viththe aid of this machine p each suooessive cup' as it' is superimposed bottom-slde up upon the one next below will have its free peripheral edge forced into fit-V ting relation with the contiguous bottomsur"` The object Will be understood by referring to the drawings in which: o

Fig. 1 is a perspective view of the device showing parts lin section.

- Fig. 2 is a detailjviewsomewhat enlarged which are employed.

Referring more particularly to the draw'- v `ings the device emloodies aframefcomprising upright rods 1, 1 adapted to support at their upper ends a cross support or' strutv 2. The lower end` of each of rods v1 is held in a socket 3 that is made integral with floor standard. An adjustable shelf '6' is mounted on'rods '1, 1 some distance above standard 5. 6 has depending bushings 9, 9 that are fixed to rods 1,71 by set bolts 10, 10. w

A countersunk annular recess 11 is made Vin the upper surface of shelf6, which recess is, adapted for the disposition of the periphery of the first cup 12 turned bottom-side up. An enlarged central aperture is made through showing a rack in fragment and gear in mesh Shelf Vthe center of'shelf 6 for the projection therethrough of stay rods 15, 15 used to hold the several cups 12lof the'mufller togethenf The lower ends of rods 15, 15 rest in sockets made 'lin members :16, 16 formedintegral with verv tioally movable ;platform 20. p

Platform 20`has apertures at 21, 21 where- ,by it can slideZ on ,rodsA 1, -1 .andfisattached "'to ver'tically movable hanger.22,1ovV adjust- - able rods 23, 23, Sleeves ;24,24 are mounted to rods 23 in such inannerfthat rods 23,23 1

can slide therethrough, whereby there is per- .mitted a given amount of 'motionz of hanger 22 indepen'dent of platform' 20. .Hanger 22 I' is reducedatr25, 25 to provide thinner portions for the through. 'v

Hanger 22'is seou'i'e'dito .thelower end ofA gear'r'ack 30. The upper endof gear rack lprojection of rods 23, 23ftheref' projects through an open'recess in stationi" aryv cross strut 2, whereby itis' permitted to move in a Vertical plane. A cable is at- V'ta'ohed through an eyejbolt o'fixed to the upper end of rack 80 and passes overaipulley x 37 supported on'shaft 38 carried'in hangersj''` 39, 39vfastene'd to any overhead structure.V A'weiglit' 41 is attached to the free end of cable'35 whereby to aid in drawing gear rack O'normally upward.r In order'fto force rack 30 the pull of weight 'zlthere isprovideda gear 45 thatis inmesh with said rack 30.v `Grear45 downwardf against is oarriedto turn -with shaft havingbearand adaptedtoturn with 88 Whereby to'pullnornially upward support' vRods 15, 15 carried on said' platform 20 Awill work upward gradually ascups 12 are built upon each other to forma'muffier. Set

-bolts' 60, are screw mounted tosockets 61,

61 of platformlO andare adaptedto engage standards 1, 1 with more or lessdegree offriction, whereby lto govern the amountof'- freedom With which said platform 20 will slide on standards 1, 1. w

fIn operation platform 20 is forced dovvn- Ward manually. Stay rods 15,15 are disposed through central aperture 141 in stationary shelf B with their ends resting in socketsV made in members 16, 1 6 of platform 270. A

cup 12 is placed in recess 11 of shelf 6, bottom side up and'over stay rods 15, 15, which are permitted to move upv'vard Vthrough the correspon ding apertures madein the bottom suri face ofcup'12. A second cup V12 is then placed on the first .cup over stay rods 15,15 which have been allowed to move upward still furt-her. Hanger 22 is-then lowered into contact With the adjacent surface of second cup 12 by turning hand wheel 52 Whereby to force the fiared edge GO of said cup 12 over the contiguous bottom edge of the first cup 12 and intolclose adherence therewith. Then each cup 12 is piled upsucccssively on .its ad- 'jacent cup 12 until theI mufiier isl completed.

Platform 20 carrying stay rods 16, 16 in vertical position thereon Will move upward automatically, as cups 12 are built upward upon each other, under the influence of Weight 55, Whereby to be in position to project rods 16 through the corresponding apertures made in each cup v12 as each is successively placed on top of the next lowermost cup 12.

Set'bolts 10, 10 may be projeeted clear through sleeves 9 and standards 1, 1, whereby 'to make a very rigid support for shelf i Havingthus described my invention what I claim is nevv and desire'to secure bylLette'rs Patent is as follovvs 1. In a cup assembling` machine, stationary means for holding a cup, movable means for pressing a second cup into close contact with the firstnamed cup and means for projecting stay rods throughsaid cups.

2. In a cup assembling machine, a member for holding a cup, a` movable member for pressing a second cup into close contact with the first cup and a hangerrconnected to said movable means, whereby toproject stay rods through saidfcups.

3. In a cup assembling machine, means for` supporting' a cup, a. movable member for forcing a, second'cup into close contact with the first named cup, gear means for actuating said movable member, and means connected with z said movable member for projecting stay rods Vthrough said. cups.

. i 4. Ina cup assembling machine, means for supporting a cup, a movable member for forcing'a second cup into' close contact With the first named cup, means for actuating said movable member,fand other means connected With said movable member for projecting stay rodsthrough said cups.
