Be it known that I, JOSEPH' 1V. Sononnnn- LEX, a citizen of the Unitedstates, resid ng Improvement in Sheet-Gauging Devices for Presses, of which the following is a specification. Th's invention has to. do with punch presses by .whichpiecesof suitableform and size are cut from metal sheets for use'in the making of can ends, or the like, and the particular improvement provided is for the purpose of properly gauging' the sheetsin their various operative positions as they An important object of the gauging dev ce which may be placed upon presses of standardform and construction Numerous other objects and advantages I of the inventionwillbe apparent as itis .better understood 1 scription, which,

from the following. detaken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

- Referring to the drawings, a

Figure 1 isaside elevat on of a standard press upon which a device embodying my invention is employed, being partially broken away to better illustrate some ofthe operating elements; p

Fig. 2' is a front end elevation, taken substantially along the line 2-2'0f Fig. 1; Fig. 3 is a plan viewof the bed of the press, being taken substantially along the broken line 3-3 in Fig. 1; and

Fig. e is a detail perspective view of the device of my invention, shown apart from the other mechanism.

The general organization of the machine, which has been shown on" the drawings for purposes of illustration, is well-known and n ed not-be d s ribed i P ticular d tai in the county of Weber and State of Utah, have invented a new and useful U invention is f theprovislon of a device for this purpose, which is automatically operable in synchronisin with the of the sheets and the action ofthe'punch; I v V i A further object is the provision of asheetv tune-, tion without likelihood of breakage, or the necessity for. frequent repair complicating the structure, or

A frame 11 supported from, base members 12 and has mounted 'in the upper part thereof a crankshaft 13 which carries a drivingpulley 1 4,across-head 15-and brake mechanism 16. -An upper slide 17 issuspended from the cross-head 15 andcarries a'punoh .18 adapted ito' cooperate with a die member (notshowny mounted in a die block 19, whichln JGU-LEII'IS supported by a ,bolste'r'plate resting upon an extension bcdplate'22 upon the frame 11. A feeding. table 23is provided above the*die :block 19.nnd is supportednat its front end by means of a bracket 2a secured to the,

bed plate 22, the rear end of said table being supported ,by means 'of a web '25] extending; between the sides of the press frame. v I

Referring now in detail to the mechanism provided by my invention, it will be noted thata short shaft 26 is mounted in bearings 27 and 28 secured to the side of the feeding table-23 and is adapted to be rotated by nean'sj ofa spiral gear 29 meshin with a spiral gear 31Ylmounted on the end of a' transverse j shaft. 32, which 1s journaled in a bearing 33and is driven from the crank shaft 13"by"ineans of a sprocket chain .34 taking over sprockets '35 and 86 mounted respectively onflthe shaft-s" 32 and A plurality ofequally spaced fingers 37 r for a purpose which will here inafter appear.

'are mounteduponthe shaft 26 and pro- A side guide" 38 is provided upon the table Qt-land a retaining bar 89 extends laterally therefrom andis adapted toprevent upward displacement of the sheets as they are successively .fed through the machine For the purpose of feeding said sheets, I employ a described. A short transverse shaft 41 is journaled in a bearing 42'secured to the edge of the table 23 and carries on its toperiodically engage and advance asheet is accomplished sprocket connection'with the" shaft 32.

mechanism which will now be" inner end an eccentric 43, which is adapted c nnection mp es mane taki g over sprocket 4'? mounted on the shaft 18 so that the sheet is advanced one step for each stroke of said punch, it being understood that the advance takes place while the punch is in its raised position.

YJhen the sheet is in position for the first cut, its forward edge rests against the forward finger 37, which at this time extendsver-tically downward and forms a stop accurately ocating said sheet in desired position; The shaft 26 rotates in such timed relation thatit makes a quarter turn at each Stroke of the punch and each revolution of the shaft 41. Upon the next feeding action, therefore, the forward edge of the sheet is brought into contact with the second finger 37, which. has by this time assumed the downward position and the sheet is held for the second stroke of the punch. Further rotation of the shaft 26 results in stopping the sheet at the proper positions for the remaining cuts to be made (there being in the present instance four cuts in the length of the sheet) and when these are completed, the sheet discharged from. the machine, f: f by gravity to any desired place of s Time the sheets are properly gauged and brought to restvat the successive operative positions by wholly automatic mechanism and without the necessity of any manual handling.

' I t is thought that the inventionand many of its attendant advantages will be under- "stood from the foregoing description, and

it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material. ad vantages, the form hereinbeforedescribed being merely a preferred embodiment thereof.

I claim:

l. A sheetgauging device for presses and the like, comprising a rotatable element arranged longitudinally of the path of travel of the sheets and having a plurality of projections thereon adapted to be successively disposedin sheet obstruction position during the rotation of said element, a transverse shaft having a camrto bear intermittently on the tops of the sheets, and means connecting said transverse shaft and rotatable element for operation in timed relation to each other.

2. A sheet gauging device forpresses and with punching dies and means foradvancing sheets of tin plate, or the like, into the sphere of action of said dies, of a rotatable element having a pluralityof projections disposed along the lengththereof and extending radially-therefrom in different directions, said projections being successively projectable into the pathof a sheet to position it at the various operating-positions, and a transverse shaft geared with said rotatable elements a second transverse shaft having a cam for intermittently propelling the sheets against said projections, and mechanism operating said transverse shafts and the punching dies. 7

4. Ina press, the combination of recipro eating dies, means comprising a cam which bears intermittently on the tops of the sheets for feeding tin sheets, or the like, into the sphere of action of said dies, and means automatically operable in timed relation .with respect to theaction of said feeding means to stop the sheet at a plurality of different points to permit the takingof successive cuts therefrom in exact predetermined order.
