' Referring to the drawing, 1 representsthe bed of a punch press, 2 the reciprocating punch head and 3 the head way.
Certain features of my improvements as V illustrated are adapted as an attachment,
the parts being mounted on a bed plate 4 adapted to be attached to the of machine screws 5.
The bed plate 45 has a. way'6 therein for the work carriage 7, this carriage being manually reciprocated, in thestructure'illustrated, by means of the lever 8 which is pivoted at 9 and connected to the carriage by means of the link 10.
bed 1 by means The work holder 11 is rotatably supported in the carriage by means of the spindle 12. This work holder is adapted to receive the hexagon head of a castellated'nut blank, as 13.
' Mounted in opposed relation to the carriage is an anvil 1 1 having a'curved work rest or eeat115 on. its face. This anvil is V supported in'a block 16 having a bore there in to receive the anvil which is cylindrical p in form, the anvil being' held in the block by means of the set screw 17.
supported in operative relation to the punch The"die 18 has a slot 19 in its'end,' thedie being supported ina bore 20in the anvil. to project over the seat 15 and being thus NVith the parts thus arranged, thework 13 is presented by the carriage so that it is supported by the seat-15 with the die enteringthe bore of the nut. To facilitate the clearance of slugs from the die the rear wall 24E of the slot 19 is rearwardly inclined. The
slugs are thus directed "into and through the nut into the passage 25' extending through charged from the rear end of the spindle into'a trough 26. I r
The work holder is rotated with a step by step movementin synchronism with the actuation of the punch by means of a star wheel the spindle 12' so that the slugs are dis 27 on the rear end of the spindle which v v coacts whenthe carriage is in its advanced position with the tappet 28 which is connected to the sprocket gear 29 driven from the chain 30. i
The details of these connections are not shown as, it is believed, they will be readily understood by those skilled inthe art.
To prevent overthrow, I provide a friction shoe 31 coacting with the spindle 12, this friction shoe being adjnstably supported by means of the set screw 82.
f When thecarriage is retracted, the work is automatically stripped from the die by means of the stripper rods 33, there being a pair of them in the structure illustrated which are projecting from each side of the die, as shownin Fig. 'r. These stripper rods are connected by the crosshead 34 at the rear of the anvil, the crosshead being ongaged'by the adjustable tappet 35 on the arm 36"which is pivoted at to the anvil supporting block and connected by the link 38 to'the carriage, so that when the carriage is fully retracted, the work is ejected.
The blank being placed in the work holder,
, the carriage is advanced to position the work V work advanced and retracted.

in proper relation ,7 to its supporting anvil and the die. These operations, in the structure illustrated, are performed manually, that is, the work placed in the holder and the Themeans for controlling the operation of the punch are not illustrated as they form no part of this invention; a a
"My improvements as I have embodied them in nut castellating machines'are highly efiicient,the work being supportedso that the punches-are light and strong and very durable. Also, the machine is of large ca;
pacity. .i
I have not attempted to illustrate or describe various modifications and adaptations which I contemplate as I believe'these disclosures will enablethose skilledin the art to embody or adapt the'same as may be de- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l r i f 1, In a punching machine, the combination of a reciprocating punch, an anvil provided with an upwardly facing segmental work rest, a slotted die projecting from said anvil above said rest, the rear wall of the slot of the diebeing rearwardly inclined, saidanvil havinga slot extending upwardly from said slot in said punch, a reciprocating work carriage adapted to position the work carried thereby upon said work rest with said die entering the work, a work holder rotatably mounted on said carriage, said work holder having a-spindle with a longitudinal opening permitting the discharge of slugs therethrougl1,.means for rotating said work holder comprising a star wheel on the spindle of the work holder, a tappet co acting with said star wheel when the carrlage is in 1ts ad vanced position, and a friction brake coacting with said work holder spindle to pre vent overthrow thereof. 7.
