lowing 1 especification.

invention relates to sheet metal forming'jmachines and has more'especial refer-.

ence too. machine adapted to out metal sheets-'finto, strips of a predetermined size and corrugate the strips thus out.

The object of my invention is to provide a sheet metal forming machine which will.

automatically cutinetal sheets into strips of a predetermined size and corrugate the stripsin asingleoperation.

further object is to'provide a machine of this character into which sheets of va-' rious sizes may be fed and which will automatically discard'the scrap cut from the corresponding parts through the several sheets and discharge the finished strips into a separate receptacle.

With. these ob ects 1n VleW the invention consists'im the novel construction and arrangement of parts, hereinafter described.

illustrated in the accompanyingdrawings,

and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions. size and minor details of construction may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

The side frames l and 2 are supported upon suitable legs 3.

A table 4 is supported at the front of the machine upon a suitable bracket 5 carried upon the side frames 1 and 2, said table extending in'hetween the side frames to a point The lower feed roll vided with a reduced portion 7 which extends through the side frame and a pinion 8 is mounted thereon, said pinion meshing with a pinion 9 carried upon the reduced portion 19 of the'upper feed roll 11. The upper feed roll is mounted in slidahle bearings 12 of the usual construction which are adjusted by means of the customary screw 13 and a pressure spring '14 is interposed for the purpose of normally holding the rolls together and allowing; a slight movement of the upper rolls-to accommodate any varying thickness in the sheets.

A. pair of splitting rolls are located adjacent the feed rolls and in a position to receive the sheets as they pass from the feed width. Each of the splitting rolls is provided with alternate collars 15 and restricted portions 16 of a width equal to the desired width of the strips to be cut and the collars of each splitting roll register with the restricted portions of the other splitting roll, thus performing a splitting action when the' sheets are passed between said rolls, splitting the sheets into strips of a width equal to the collars on the splitting rolls. The lower splitting roll 17 is journaled infthe side frames 1 and 2 and is provided upon one extremity with a pinion 18. which meshes Specification of Letters Patent. ianigti SQpt. 28, 1915.

.rolls and split the same into thedesired 24, carried upon a oar 25 extending transversely between the side'fiangessextend into said grooves for the purpose" of guiding the sheets from the feed rolls into the splitting rolls.

A fixed shear blade 26 is located beyond the splitting rolls and is preferably mounted upon the blocks 27 by means of screws 28, said blocks being carried in the side frames of the'machine.

A screw 29 is passed downwardly through engagement with the fixed shear blade 26 as will be hereinafter explained.

-An arm 34 is pivoted to each of the side vframes 1 and 2 as at 35 and each of said arms is provided with a roller 36 which bears upon the lower edge of the reciprocating shear blade. a I A roller 37 is provided 11 on the extremity of each of the arms 34, sai rollers normally resting upon the shaft 38 and adaptedto be glrligitged by the cams 39 provided upon said a 20 Each of the arms 34 'is provided with a recess 40 adapted to receive the cams 39 as they are moved into the raised position, thusallowing a quick return of the recip-. frocating shear blade.

A tension spring 41 is connected tothe reciprocating shear blade andattach'edfiin an suitablemanner to the frame of the machinc, preferably to a rod 42 connected between the side frames.

In some instances it is desirhble to punch the strips at spaced intervals and for this purpose the upper roll. 52 is provided with pins 66 which are removably placed around V the periphery thereof, said pins being adapted to register with the conical de ressions 67 in the lower roll 53 as said rol rotate. When it is desired to produce the strips withoutpunching the pins 66 mav be removed from the-u per roll .52. As thestri a pass from the ro 52 and 53 they are eposited upon alchute which carries them to suitable corrugat rolls. This chute is preferably form of a series of narrow plates,68 which are held in an inclined pothe-l rackets 69 which are carried betweenthe sideframes and partitions 7-70 are secured between the edgesiof each of'saidplate s. A finger 71 is secured to thejbrackets'69 adjacent the verof said finger tical'walls' 72, the extremity mm roll 151 spring 741 being pro- .vide'd rornormny holding said finger in contact with said corru roll.

of said parts beingloosely mounted uponthe shaft 50. Y

The fixed clutch member 89 is fixedly con nected to-the shaft 50 by means of a key 90 and is formed wit-h an annular groove 91 T he' locking member 92 is slidab'ly mounted in a longi: tudinal slot 93 in the fixed clutch member, a

, recess 9% being provided in the loose clutch member for the purpose of receiving the ex tremity of said locking member.

The locking member 92 is provided with a slot 95, one face of which is rounded at 9-6.

An expansion spring 97 is located in a suitable channel 98 formed in the fixed clutch member engaging with a pin 99 carried by side frame 2, the extremity of said lever be said cam being adapted to contact withthe ing provided with a shoulder 103 and with a tapered finger 101i adapted to engage with the rounded edge 96 of the locking member. A spring pressed" 'rod 105 is slidably carried in abracket 106 and is held in contact withthe extremity 107 of the lever 101 'by meansof a compression spring 108.

A cam 109 is provided upon the shaft 38,

extremity 107 of the lever 101 as the shaft '38 rotates, thus throwing the finger 10a of said lever out of engagement with the looking member 92.

A sprocket wheel 110 is carried upon the shaft 38 and is connected to a sprocket wheel 111 upon the shaft 7 4: of the lower corrugat ing-roll by means of a sprocket chain 112, thus continuously driving the corrugating rolls.

The operation of the device'is as follows: The sheets to be out into and corrugated, and, if desired punched, ar placed upon the -table 4t and fed between the fee'drolls 6; and 11 which carry said sheets through the splitting rolls splitting the sheets intostrips of the desired width and feeding them into the shears. The device is so timed that as the strips have passed through the shears, a proper distance, the shaft- 50 will have rotated into a position, bringing the locking member 92 upon the fixed clutch member into engagement with the finger 10i of the lever 101, the face 96 of the locking member engaging with the tapered-face of the finger, thus drawing the locking member out of engagement with the recess 9i in the loose clutch member the shoulder 103 upon the lever engaging with the side face of the locking member as shown in Fig. 2 of the drawings bringing the feed rolls and splitting rolls to a stop at which time the shears are operated cutting the strips the proper length. As the shaft 38 rotates, the cam 109 will then engage the extremity 107 of the lever throwing the finger 104: out of engagement with the locking member 92 allowing the locking member to again engage the recess-.94: of the loose clutch member and causing the feed rolls and splitting rolls to again rotate, the strips.

being passed through theifeed rolls 52 and 53 and upon the vibrating chute 68, the vibration imparted to this chute by means of the finger 71 contacting with the lower corrugating roll 73, causing the strips to be easily separated and dropped into their place, each strip sliding between two of the partitions 70. The strips then pass through the; corrugating rolls where they are corrugated -and the finished strips as shown in Fig. 8 of the drawings are discharged upon the inclined plate 8i and passed from the machine upon the inclined tracks 82, any strips of scrap which are too narrow for use being dropped between the tracks 82.
