Application filed June 21, 1916. Serial No. 104,971.

To all whom it may concern:

Be it known that I, TRUMAN J. Pnn'r, a citizen of the United States of America, and a resident of Monticello, Jones county, Iowa, have invented certain new and useful improvements in Crimping-Machines, of which the following is a specification.

My invention relates to improvements in crimping machines, and the object of my improvement is to furnish mechanism adapted to'crimp the open end of a hollow cylindrical body to adapt the latter for use as a receptacle or for other purposes. This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my crimping machine. Fig. 2 is an elevation of the rear of the forward frame part of the ma chine, with the parts of the machine which are connected thereto sectioned away. .Fig. 3 is a like elevation showing certain moving parts in a different position. Fig. 4 is a rear elevation of said machine. Fig. 5 is aside elevation of the machine, with parts of the supporting structures'for the mechanism sectioned away. Fig. 6 is an enlarged detail view of the two parallel crimping rollers as employed in crimping a cylindris cal body, and showing the trip-lever about to be operated by the action'of the upper crimping roller on the crimped body. Fig. 7 is a perspective view ofthe hollow cylindrical body before crimping, and Fig 8 is a like view of said'body after one end of it' has been crim'ped.

Similar numerals of reference denote corresponding parts throughout the several views.

Myv improved device is primarily intended for use in crimping one open end of a hollow metallic cylinder to form the body of 'a' basket or other receptacle.

The supporting frame of my maoh1ne 4 comprises forward and rear corner standards 64 and 63. -The standards 64 are fixedly connected in front byfa plate 65, and the rear standards 63 are connected in the rear fixedly by a like plate 66. on each side,

the forward and rear standards are connected by'means of side plates 67, said forward, rear 'and side plates extending from the bottom of said standards only partly upwardly toward their tops. a 1

A i- L- p d brack t 5 is mounted on the upper part'of the forward plate by means of bolts, and has in its upwardly turned limb a vertical bearing socket in which is rotatably mounted the depending spindle 9 of thepinion 10 with concaved beveled teeth. On the under surface of said pinion are crown teeth 11.

Referring to Fig. 5, the numeral 1 denotes a shaft having diminished parts mounted rotatably in bearing openings in cross-bars between the forward and the rear uprights respectively, and on the rearwardly extending part of said shaft are fixedly mounted a gear-wheel 6 and the belt-wheel 7, and also a loosely mounted belt-wheel 8. On the forwardly extending end of said shaft is removably mounted a longitudinally crimped forming-head 2 and on the front end of said head is fixed an axial spindle having an enlarged end 3, said spindle and its enlarged part being rotatably seated at the'bottom of a T-shapedgroove' in said bracket 5 so that the forming head and itsLspindle may be dismounted from the bracket when desired. On the forwardend of the forming-head. 2 is a fixed gear 12 whose teeth mesh with the crown teeth 11 on the concave pinion 10.

The numerals l6'and 17' denote cross-bars mounted between the forward standards 64 and the rear standards 63 respectively. The cross-bar 16 has. on its ends (not shown) diminished portions which are seated in grooves on..the innervertical edges of the standards 64 to allow the cross-bar to be swung upwardly a shortdistance. The rear CI'OSSfbEtI 17 is placed between two vertical hangers depending from either end of the cross-bar 18, theends of the latter being diminishedto likewise slide in grooves on the inner edges of the rear standards 63, and the cross-bar 1 7 has oppositely extending pintles 62 mounted to rock in bearing sockets in said hangers. A shaft 13 has diminished 'parts mounted in bearing orifices in the cross-bars 16 and.17, and carries on its rearwardlv extending end'a gear-wheel 15meshmg with the gear-wheel. 6, the shaft 13' being arranged a little above the other shaft 1. On the forwardly extending end of the shaft13 is detachably mounted a longitudinally grooved forming-head 1e adapted to mesh or coact with the forming-head 2' when the shaft 13 is moved downwardly. Between the upper ends of the forward standards Stand the rear Standards 63, re-

spectively, are fixed the cross bars 22 and 19. A coiled compression spring 21 is engaged between the rear cross-bars 18 and 19, about alined pins 20, and serves to yieldingly push downwardly the cross-bar 18 with its con nected pivotal cross-bar 17 to retain the gear-wheel 15 in mesh with the gear 6. A

tension spring 23 is connected between the,

. meral 35 denotes a medial vertical slot in the lower part of the forward plate 65, and

a pedal lever 34 is passed 'rearwardly through said slot, and has its rear end pivotally connected to the eye on an eye-bolt 58 mounted in the lower end of the rear plate 66. Referring now to Figs. 2 and 3, in Fig.2 is shown the position of the up and down movable roll 13 when disengaged from the other roll 1.

The numeral 24 denotes Y a U shaped bar, whose upper endsxare bent forwardly and; secured to theupper edge of the crossbar 16 at opposite sides ofthe roll 13. A swinging arm .25 is pivotally connected at 26 to the middle of the loop of the U-shaped .bar 24, and has its lower end pivotally connected at 30 to the upper end of the bar 31 whose lower end is provided with a fork 32 which bestrides the middle of the 1ever34, and is pivotally connected thereto by means of a pivot-bolt 33. Aoshort swing-arm 28 has one end pivotedat 27 to the rear face of the plate 65 and has its other end pivoted at 29 to the lower part of the w swing-arm above the pivotal connection 30 of .the arm 31 therewith. When the said said rolls from each other.

arms are in the positions shown in said Fig. 2, the spring 23 has 'moved the cross-bar .16 and U-shaped bar 24 upwardly, disengaging rollsinto mesh, the pedal-lever 34 is pushed downwardly thus shifting the pivotallyconnected arms-25, 28 and 31 into overlapping alinement which places them ona dead center and holds the '1'01113 in its lowered position with the forming- heads 14 and 2 in'mesh. A stop-pin 47 in the rear plate 65 prevents the said arms from swinging too far in one direction.

I have provided mechanism for throwing said armsfrom their position of dead cen ter to permit the spring .23 to react and draw the former-head 14 out of .mesh with the former-head 2. A short rock-shaft 44' is mounted in a bearing orifice in the lower part of the forward plate 65 and has arock arm 51 fixed on its forward end/ A short lever 53 is pivotallyflconnected at 54 to the forward part of the frame, and has one end pivoted to the upper end of a link 52 whose To bringv said 7 of the lever arm is directed between the two forming-heads at one side thereof but so as to not interfere with their rotations.

Referring now to Figs. 2 and 3, the numeral *denotes a rock-arm fixed in an end of. the shaft 44 and has a tappet body 46 threaded on its free end. A curved arm43 is fixed on and depends from said shaft 44. The numeral 37 denotes aslide-plate having verticalslots'57 for the passage of securing screws 56 on which said plate is mounted to slide up and down on'the rear faceof the front plate The lower end of the plate 37 has an angular foot 39. A vertioal'rod 40 is mounted on the plate to slide up and down in staples 41, with its upper end under and adapted to engage the lower face of the foot 39, 'whenlifte'd. The flowerend of the rod 40 has a fork 42 bestriding the end of the curved arm 43. The upper end ofthe slide plate 37 is bent over downwardly .at 38, and said plate has an opening just below thet'ip of this bent-over part.

Referring now to Fig. 5, the nu'meral49 denotesa hand-lever pivoted at its lower end between lugs 48 on the front plate 65. Both the front. plate 65 and the rear plate 66 have horizontally alined bearing openings in which is movable a slide-rod 36 provided with a notch 59 in its. upper. edge. To the front end of the rod is pivotally con nected the hand lever .49. A belt-shifting arm 61 is fixed on the rear end of the rod 36, and a coiled compression spring 60 is mounted on said rod between the arm 61 and,

the T6511 face of the rear plate 66, and tends to yielding ly shift the rod 36 rearwardly. The upper curved end 38 of the slide plate 37 rides upon theupper edge of the rod 36,.since said .rod .passes through the opening in said slide-plate.

Operation; The moving parts of the machine being in the inoperative positions shown in Figs. 2, 3 and 5, when it is desired to operate the machine the pedal lever 34 is depressed, after the u'ncrimped, cylinder 68 has been mounted upon the upper forming body 14 This draws the rock arms 25, 28 and 31 into the dead center position shown in Fig. 3, stretching thespring 23 and drawing the roller 13 to its lower position. The

- hand-lever 49 is then swung forwardly causing the shifting-arm 36 to shift a drive-belt,

(not shown), from the loose pulley 8 to the tight pulley 7, which places-the intermeshed gears 6 and 15 in rotationwith their form- 1ng- heads 2 and 14, thus crimping the cylinder 68 to the form shown "in Fig. 8. When the rod 36 is drawn forwardly to said position, the bent tip 38 of the slide plate 37 drops into the notch-59, holding therod in that position.

Wh en the cylinder 68 is fullyacrimped at 70 the operation of the machine is automatically stopped in the following manner: The fold-over joint 69 of the cylinder, as

shown in Fig. 6, as the crimping operation is completed, rotates into engagement with and pushes down the finger 55 of the lever 53 thus causing the link 52 to rock upwardly the rock-arm 51, rocking the shaft 442 to swing the tappet body 46 against the swing arm 31. The arms 28 and 31 are then swung oil their dead center so that the spring 23 can react to rock upwardly the formingrhead 14 so that the crimped cylinder may be dismounted therefrom. Simultaneously, the rock-arm 4E3 pushes up the slide-rod 40 against the foot 39 on the slideplate 37, thus pushing up the slide-plate and disengaging its bent-over end 38 from the rod 36 so that the spring may react and shift the driving-belt back upon the loose pulley. I I

It is to be understood that various changes may be made in the forms, arrangement and operation of the coacting parts of my machine, without departing from the principles of the invention or the scope of its protection.

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