Specification of Letters Patent.

Patented July 23, 1918.

Application filed June 25, 1914. Serial No. 847,302.

To all whom it may concern:

Be it knownthat I, OBERLIN SMITH, of Bridgeton, in the county of Cumberland, and in the State of New Jersey, have invented a certain new and useful Improvement in Presses, and do hereby declare that the following is a full, clear, and exact descri tion thereof.

y invention relates to presses employing a reciprocating tool-carrying ram and in particular to presses in which a plurality of operations may be simultaneously performed, and the object of my invention is generally to improve the construction of presses of this class in. such matters as ease and convenience of access to the tools, multiplication of the number of operations that may simultaneously be performed, increasing the strength or stiffness of the structure, while at the same time rendering it compact, and simplifying and lessening the cost of construction, and to attain this object and provide a press having other advantages which those skilled in the art will readily appreciate, my invention consists in the press having the construction substantially ashereinafter specified and claimed.

As it will be recognized my invention may be embodied in structures of various forms, but it will sufficiently illustrate my invention to show one embodiment thereof, and in the accompanying drawings- Figure 1 is a front elevation of a press embodying my invention;

Fig. 2is a side elevation thereof;

Fig. .3 is a vertical section from front to rear;

Fig. 4 is a top plan view;

Fig. 5 is a horizontal section on the line 5-5 of Fig. 3, in a plane just above the diecarrying dial, a portion of the latter being broken away to reveal the structure below;

Fig. 6 is a detail view in vertical section of the cork feeding device, the press shown to illustrate my invention being one for the manufacture of the familiar bottle closure composed of united disks of sheet metal and cork.

Referring to' the drawings in connection with a detailed description of the press shown, it will be found that the bed or frame 10 is in the form of a vertical standard to the top of which is secured a table 11. Upon the top of the table is journaled a horizontally rotatable dial 12 having a circular series of holes 120 each for the reception of the blank or work, beneath which the bed is provided with a circular series of dies 13, the press shown being one in which the tools consist of cooperating punches and dies and the punches being carried by a ram 14. The ram 14 passes centrally through the dial and table having above the dial a head 15 in the form, as shown, of a disk with a series .of radial notches, or slots in its periphery,

or circumference, each of which is adapted to detachably hold a suitable punch,,or tool to cooperate with an alining die below. The ram has a body, which for convenience of construction is preferably cylindrical, which has a sliding lit in a bearing in the upper part of the standard, said bearing being in the form of a sleeve 16 which is mounted in the upper part of the standard and externally has a tapering, or conical form so that When a nut thereon is moved longitudinally (it being a split sleeve) it may be adjusted to secure the desired bearing fit and to compensate for wear. As the ram-reciprocating means is below the dial supporting table it will be seen that there is no frame structure required that conceals, or obstructs access to the tools, but the latter above the dies and punches areso completely exposed that the fullest possible access thereto is possible and the number of tools that may be provided is not diminished, or reduced, as would be the case with such an arrangement of the frame structure, as would house, or cover portions of the toolcarrying head and dial.

Since the bearing body of the ram is cylindrical in the case of the press shown, I provide a stud or post 17 which is attached to the ram head and passes through a hole 18 in the table which it slidably fits and thereby the punch-carrying head is prevented from rotating. Obviously, if the ram body were given a rectangular, or other flat sided form no device, such as the stop or post would be necessary to prevent it from rotating.

A very important advantage from my construction is the possibility of making the ram of great length compared with the height of the press, that is to say, without enlarging the size of the press, but on the contrary providing a very compact structure,

the ram can be of such great length as greatly to add to the stifiness of the structure and preclude laterial lost motions of the ram.

i'The ram-reciprocating crank shaft Q'Ois 10urnaled 1n horizontal bearings an the press frame, being provided at oneend with a pui l ey andfly wheel 1'9. 'Moun'ted on the erank portion of the shaft is a pitin'an .bloek 21 ito which :i'ssecured arod that projects on opposite sides t hereof right angles to the crank shaft, and slidably engages openings in the shank, -'or stem of the pensatefor defects ofconstructionsothat nc greatpains need be taken *by the work man-- for' accurate constructionby machining parts, for other olose work so that ;nothing beyondgordinary workmanship is required. The dial is rotated step my step to carry -the =workfroni die to die, and for this purpose its periphery is provided with ratchet teed-i 23 -agd'a pted' to be engaged by a feed pawl-124 carried by" {a "rocking 'lever 25 mounted to rock on a horizontal pivot-26 projedting from the side oilf the standard. llhe'lo'wer end 27.01? the lever is slotted and theslot is a crank pin 28 upon the crank 'sh'a ft 2t). i 'As' hasbefore'beenstated, the-;press illustrating one einbodiment of my invention is used in the ina r'iufacture of bottle closures. These are ina'de of -disks-of metal, ai aX p aper and/"cork; f l lre ;paper -i%n strip form Wound into a rol liis fsu ppor'ted by a reel, the strip being carried from the latter and passed between a "pair of feed rollers, 29 journaled horizontally inbearings on'the top of the table, and for operating the feed rollers {one ofthem hasupononetend a rat'chetwh'eel -30 adapted to be actuated by a suitable pawl 13d. :Said-pa-Wliscarriediby a rocking arm '32 which by arod or ;pit1nan 83 is connected ivi tlrthe" dial'f-dndeXing-ilever25. The strip of 7 paper after ;passi'ng 3beyondthe feed rollers isfdelivered" in pos'ition to be operated upon by apunch'and its'cooperatingdie so asto form the disk. Mea'nsmre providedfor ing devices which may have the form and -=arrangement best shown in -Fig. 5. The

table 11 of the press immediately below the dial has two segmental recesses in which, respectively are placed -a' curvi l i=near heating pipe 34' that is-suppliedwith steam'and a curvilinear cooling pipej'345'0 which is supplied :with cold water. The disks by the rota tion oftihe dial are earried above the heating and/cooling pipes, -and are thereby subjected to their influences so that, first, they are heated, and thereafter are cooled.

The eork .disks eareplaced. in a stack, or pile in a vertical tubular reservoir 35, "which is supported on the top of the press table with its 'l-owerend {in position to diseharge a. i cork disk at a time to the stop of the dial in position'to be engaged by a reciprocating feed bar, or slide 36, which engages the lowerinost cor-k and slides" it into "position b'e'-,

I Said slide is engagedby one arm of a bell crank "lever 87 pivoted to a-n arm -or "bracket 38 rising ffrom the t able; whose other arm has a socket which receives the lower end of a pitinan 39iwh'oseupper end engafges a socket 40 in arm 41 carried by the rain;sothatnp'on the descent of the-rain the bell: cranklever wilfl-be moved i-n-thekdirection to retractthe sl i'de while upon the; ascent of the ram a spring eonnec'ted with thebelflf crank lever andwith the ram arm "Q1 will rock the latter in v the reverse. direction to}impart a cork-disk "feedi'irgfi'noveme'nt *tofth feeding slide.
