Reference is made to the above-mentioned patent to Stevenson and also to his patents numbered 1,164,026 and 1,164,028 .for purposes of, comparison and determination'of the character and scope of the present invention. It should be.

noted that in substantially thetime required for the passage'of one bar through a punching machine a pair'of car center-sill sections are completely punched not only with .alined holes through the web and all of the flanges, but with web holes out, of alinement and with the perforations either in the web or the flanges being of different diameters if desired,

Referring now more particularly to the drawings and to the;

- Construction of the machine in' general A heavy duty multiple punch A has a base 10,

spaced side, housings 11 connected by a top crossbeam 12 which carries the bearings for an op-- erating shaft 13. The punch has; upper and lower., jaws l4and, 15 respectivelyand a punch slide 16 mounted for vreciprocation in the side housings and a consequent up-and-down movement inthe vicinity. of the upper jaw 14. Fixed in the lowerjaw 15 is a bed plate 17. The construction as thus far described, together with the operating motors, power transmitting devices, eccentric 18 and connections between the eccentrio and slide 16, are allof conventionaldesign.

Although the work may be fed through the machinaby hand, nevertheless it is preferred to use one of the various conventional automatic work feeddevices such as indicated at 19. As is well known such'a device may be a simple friction feed of the work against limiting stopsor. it may involve automatic spacing arrangements,

or templates, or both. Insofar as the present invention is concerned the particular type of automatic feed isunimportant." V The upper and'lower punch-and die plates associated mechanism A lower plate or table B is securely bolted and to the bed plate or block '17 and remains fixed throughout the operation of the machine An upper, plate 0 is securely bolted to the bottom face of slide 16 and reciprocates therewith. At the rear it carries fixed brackets 20 pivotally connected to arms 21which have their rear ends 22, arranged byfpinand slotconnections 23 with ears 24 projecting rearwardly from the opDOSite side housings 11. -The arms 21 accordingly'have pivotal movement from their rear ends in accordance with the up-and-down movement, of'

.the slide 16 and the upper plateC fixed thereo The purpose of this movement will be described later.

The lower plate or table B has rearward extensions on opposite sides of the center line, one of which is indicated at 30. These are suitably connected with pedestals 31, the upper ends 32 of which are bolted toextensions 33 on the main frame of the punch A. This provides additional support and reinforcement for the rear portion of the table B which overhangs the bed plate 17.

The lower plate and associated mechanism The lower fixedplate or table B is of generally rectangular form and has arranged thereon on each side of its transverse center line a series of dies. 1

Commencing atthe forward end of the machine (see Fig. 2) the first set of one series is indicated at-40. The dies 41 are vertically disposed and are of different diameters. They are set in'a die-block'42 which is fixed on the table B by a T-bolt 43 and nut, the bolt being arranged in slot 44 allowing for rearrangement vbetween successive operations if desired. The rear end of the block 42 is shouldered at 45 and held table B as indicated at 47.

in position by a'shoulder block 46 bolted tothe The second die set is shown in Fig. 2 at 48 1 comprising 'a slidable die-block 49 containing a pair of difierent sized vertically arranged dies 50. This die-block is arranged in a T-slot 51 cut 'in' the table B and is movable to various positions longitudinally of the table and laterally of the work by reason of its connection,

with a rack bar 52 meshing with a gear. 53..

The gear 53 is rotated from a hand wheel 54 through a pinion 55 cutv in the lower end of a vertical. sleeve 56.f This pinion meshes with a gear 5'7, mounted for rotation on a stud 58 projecting. from'the upper surface of the table B, and which'in turn meshes with. the gear 53 also loosely mounted on'a similar stud 59 set in'the table. As shown clearly in Fig. 5 of the f drawings, the sleeve 56 is extended vertically above the hand wheel 54 a considerable distance and on thisextended portion, gear-teeth 60 arev cut and meshed with a gear 61 so that a rack bar 62 is driven through a trainv of gearing attached to the lower face of the upper plate C for the purpose of moving an adjustable punch block in the upper plate in synchronism with the movements of the adjustable die-block in the fixed table. The sleeve 56 is rotatively mounted on a spindle 64, the lower end of which is fixed in the table B. v

The two die sets 40 and 48 are for cooperation in the punching of holes in the web of the work. The next set of "dies is for cooperation in the punching of the flanges of the web. For this purpose a guide-block is secured in position on the top surface ofthe fixed table B. This guide-block has an exterior configuration in cross section corresponding to a channel- -shaped portion of the work to be punched, so .that in passing through the machine the bar lies with its web in a horizontal plane, one of its lower flanges and the opposed top flange projecting downwardly over the slightly tapered walls of the guide-block 70 (see Figs. 6'and 7). The forward end of the guide-block 70 is provided with sets of horizontally arranged dies 71 and 72 oppositely faced to contact with the inner faces of the flanges as the work passes over the block. Inasmuch as the single flange Theaupper plate and associated mechanism The'upper plate C has fixed to the lower face thereof sets of vertical punches 130each comprising in the present embodiment two, punches of different diameters in a punch block 131, the. latter being positioned by shouldered engagement with the plate as, indicated at 132 and secured by a T,-bo1t'133 in a slot134 in the plate- The punches ofthese setsfcooperate with the vertical dies 41gof the fixed diesets on-the lower plate or, table B. H r H Each of the rack bars .62, previously'mentiong ed, carries a punch block 136 slidably arranged in a T-slot 137 inv the movable plate C. This block, .in each instance, carries a pair of verticalpunches 140, of different diameters which are maintained in cooperative relation with the dies of. die sets 48, .inthe lowertable, by the upper and lower rack bars 62 and 52 movable back and forth in unison by the gearing previ-'- ously described, underthe control of the, hand wheel 54. 1

IA. traveling rig 150, best shownin Figs. 4 and .12 of the. drawings,.is mounted for longitudinal movement on the plate C, that is. a movement transversely of the. direction of 'feed of the work. This rig comprises a bracket 151 upturned at'its forward end and having a sliding connection in a T-slotted plate 152 fixed to the forward edge of the plate C. Thevbracket 151 extends rearwardly and downwardly to a level 149 where ithas bolted upon it a housing member 153. The housing is positioned.directlybelow and" centrally of the rack bar 62 which carries the laterallyadjustable punches140. Bolts154 pass through the housing 153 and'tap into the rack bar.6 2 as clearly shown in Figs. 11 and 12. The housing 153 provides two pockets 155 and 156. Within the pocket 155 a segmental orfan gear 157 is fixed ona hollow key stud 158 which" also has secured to, it,; exteriorly of the housing, 'a

beveled pinion 160. The stud 158 isrotatively mountedin the housing 153 and may be rotated in either direction by the beveled pinion 160. The segmental gear l5'7 engages a rack member lfil which extends toward the center line of the machine and carries at its inner end a gag' member 1'62 which provides for the selective operation of vertical punches'140. Thesaid rack member carries a pointed pin 163 of a detent mechanism which alsov comprises aspring pressed plate 164' positioned in the pocket 156 and having three spaced indentations 165 for three different positions of the gag member. A's shown in Fig. 11'

the gag is in neutral position whereby actuation of the plate C allows both punches 140 to recede upon contact with the work without effecting perforation. 'Diagonally opposite corners of the 60 ;member 162 areraised at 166 and 167'to provide gags movable into and out. of position between the plate C and one or the other .of punches 140. The segmental gear 157 is con-, trolled as to 'rotative movementby a handle 170 .fixed. on a shaft 171 journaled in brackets 172 'fixed to the top surface of plate C near the forward edge thereof. The shaft 1'71 extends to the. end of the movable plate C asfshown in Fig. '4 of the drawings and there is connected .by chain and sprocket transmission 173 to another shaft 174 journaled in suitable end bearings 175 on the underside of the plate C at the rear thereof. The shaft 174 is splined as indicated at 176 to allow a beveled pinion' 177 to .ride longitudinally thereon. This pinion is rotatively driven. by the shaft 174 and rotatively supported on asmall bracket 178 fixed to a side' wall of the housing 153 "so asto be in a continuous mesh with the beveled pinion 160 connected to the-fan gear 157. The plate 152 may be provided with suitable-template indicat-.

ing 'chart cooperative with apointer or other mark carriedby theupturned end of thebracket 150 so that the operator may readily set the moving punches across the work to desired position."

" The splined The rig and'actuating mechanism as above described is duplicated on the opposite side of the machine for the adjustable punches of the other series. I i

Thevamou s' 'gags selective operation of the I 1 punches I i The gags for operating the adjustable vertical punches have already been described. Gags 180 for selective operation of the punches of fixed sets 130 each comprise-a slotted plate 181 strad-' dling the securing bolt 133which holds the punch block'131 in position'. The plate isprovided with a downwardly extending handle 182 and may he slid from a position outof engagement with tions over either punch.

The gagsfor the horizontal punches, which are either of the: punches of a set to inward posibest shown in Figs. 2, 6 and 7 of the drawings,

comprisehandles and operating pins 191;

the latter being arranged in slide bearings 19 2- a'nd'carrying gag blocks 193. By movement of the handles the gag blocks are located in back of the punch which it is intended to-operate and each gag block isbacked up by a member 194 gags are similar for the punches of the upper horizontal level as well as all of the punches of the lowerlever. Another gag 200 and operatingihandle 201 therefor is shown at'the top This selectively conof Fig. 3 in the drawings. trols the operation of the automatic feedshown in-Figs. 1 and2i'nvo1vin'g a rack bar 202, gear 203, shaft 204 and transmission devices 205 connecting to a pawl andratchet mechanism'206.

' Operation As anexample of the operation of the ma-' chine A. R. A. car center-sill sections of right and left form are fed into the machine over the respective guide-blocks '70 on opposite sides of the center line. The fixed vertical dies have been set and bolted inpr'oper position on the table B and their cooperative punches bolted in 5 position on the plate C. The webs of the sepa rate car center-sill sections rest respectively on the'tops of the die-blocks in each series and the downward flanges straddle these blocks-and also" the hold-down block 46. It is usual construetion to provide a large number of perforations in the web which are in longitudinal alinement.

The fixed dies 41 and their cooperative punches relation'of the'shaft 174 and the pinion 177 allows the entire rig to be moved in accordance with actuation of the rack bar 62- so'that in adjusting'the vertical punches 140 the traveling rig'is also adjusted and in any positionof adjustment it is "capable of operating-the gag member162 for-selection of the proper punch.
