Referring to these drawing: it will be seen that the press comprises a base plate 10 having upwardly extending: flanges 11, this plate being formed to support in- Patent-ed Stand "5, llilii h tit) strumentalities which will be later de-- scribed. Mounted upon this plate, in any suitable manner, is the base, designated generally 12, which is illustrated as approximately rectangular in cross section and with sides extending upward and inward, these sides bein preferably cut-away so as to make the iase relatively light and permit access to the parts inclosed within the base. Mounted upon the base in any suitable mam ner and either bolted thereto or formed integral therewith, is the bed 13 of thepress. This bed is relatively thick and solid and is formed with a centrally disposed cylinder 14 within which a piston 15 operates in the usual manner.

Extending upward from the bed on each side of the press are a pair of uprights 16, the inner faces of which uprights extend vertically upward. The two uprights 16 disposed at the front of the press are formed with transversely extending lugs 17, for a purpose which will be later stated. The

outer faces of the uprights 16, which uprights constitute guides for the buck-head and piston block, are inwardly beveled as at 18 and then outwardly extended to provide lugs 19, which project beyond the edge faces of the uprights, the upper faces of -these lugs being rounded. The bed is also formed with an outwardly projecting flange 20 at its front, the upper face of the flange l)\.' ing coincident with the upper face of the bed and this flange being perforated as at 21 for the passage of limiting bolts 22, the purposeof which will be later described.

Extending rearward and upward from the bed are the arms 23, which at their upper ends are transversely recessed for the purpose of supporting the bearing blocks 24, which are provided with suitable ournal hearings forthe extremities of a transverse shaft 25. The buck-head, wh ch is designated generally26, has 'a rearwardly and downwardly extending arm 27, the shaft 25 constituting 'trunnions for said arm, resting in the bearings 24 and to the outer extremity of this arm 27, there is pivcally attached a link 28 and pivoted to this link is a counterweight 29, the upper end of which is bifui'rcated for the passage of a bolt 30, which connects the link to the counterweight.

the link 28, which is held to the arm by the bolt 31. The side faces of the counterweight downward and inward, so that when the counterweight is in its extreme lowered po- The arm 27 is also bifurcated for the reception of the upper end of this rib and resting upon the upper fa e of the buck-head are the forward and rear yokesBG and 37. These yokes extend transversely of the machine and are bent over at their outer ends, as at 38; and then bent inward as at 39, these inwardly extending ends forming lugs which are so shaped as to engage beneath and have snug engagement with the lugs 19, in the manner illustrated in Fig. 1. These yokesa're connected to each other-by a pair of longitudinally extending bolts 40, ,each of these bolts being threaded in opposite directions, these threaded portions passing through the front and rear yokes and being provided on each threaded portion with the clamping nuts flush with th forward face of the buck-head but extends rearward beyond the rear. edge of the buck-head and over the arm 27.

For the purpose of longitudinally shift-- ing the yokes 36 and 37, I provide a bracket 42, which extends out from the front of the buck-head at the middle thereof and mount on this bracket an upwardly extending operating lever 43, which is connectedby links 44 to an ear 45 projecting out from the yoke 36. It will be obvious now that by shifting the lever 43 in one direction or the other, the yokes will be shifted from a position in engagement with the lugs 19 to a position out of engagement, that is, to aposition be tween the uprights 16. The rib is pro vided with a stop 46. which limits the rearthcrmost positi m,-they will be in staggered relation to the uprights 16' and, therefore, the bucloliead is entirely released from its engagement with these uprights and the counterweight will act to draw the buckhcadup, When, however, the lever is thrown in a contrary position, the'yokcs will be drawn in alinement with the uprights 1(3 and the lugs 39 and 19 will be interlocked with each other. 7

For the purpose of locking the b u-lchead in its raised position and preventing any aicidental descent of the buck-head, due for instance to the breaking of the pivot bolts which connert the counterweight to the buck-head, I provide latches 47. There are on each side of the arm 27. these latches bemg each provided .with a rearwardly prothe arm 27 with the link connected to the counterweight. The latches 47 are pivotally mounted upon a: bracket 49 projecting out from the base and are shown as being pivoted upon a bolt passing through the bracket and through the two latches. The two latches are connected at their lower ends by a cross bar 50 and this cross bar extends downward and forwardjn the form of a curved arm 51 and is pivotally connected to ears on a transverse cross bar 52. Depending from the under face of the bed are guides 53, through which transverse rods 54 pass, these rods being connected to a cross 1 bar 52, in turn connected to the arin 51, and

" lower the buck-head under these circumprovided with a treadle plate.

pivotally supported upon a bracket 56 is a bell crank lever 57, the upper end of which has a cross bar which is connected to the two rods 54., and the lower end of which is connected by a link 58 to a treadl'e lever 59 pivoted at its rear end upon upstanding ears 60 and extending out through an opening in the front wall of the base and Springs 61 surround the rods 54 and bear against the guides 53 and thus urge the latches -17 downward'and outward into the path of movement of the pivot pin 31, [which pivot pin or bolt extends out laterally beyond the coacting ears on the arm 27. f

Now when the buck-head is raised, the connecting bolt or pin 31 moves downward and sliding against thebeveled faces of .the

lugs 48 forces the latches inward until the pivot bolt 31 has passed below the lugs, whereupon the springs '61 force the latches outward. Now. if an attemptbe made to stances, the. pivot pin or bolt will bear against the detent lugs 48 and the buckhead cannot be lowered. Thus if the coun terweight is released from its engagement with the buck-head by the breaking of bolts or pins, the buck-head cannot drop because of the latches. If it'is desired to lower the buck-head it is only necessary to depress the treadle lever 59 and this withdraws the latches out of the path of movement of the bolt, 21 and the buck-head may be lowered. Itwill be seen that when the buck-head is raised, these latches lock automatically and that they are unlocked by the foot lever.

The piston 15 as illustrated in Fig. 2, is formed at its bottomwit-h a. circumferem tial groove or channel 62 and a metal plate' of the channel 62. This channel is designed for the carriage of a piston ring. The upper face of the piston has a pair of screwthreaded openings 63 by which the piston block 64 is held to the piston. This piston block G l-is formed with an annular recess 65,'on its under face, within which the upper end of the piston is disposed. Mounted upon the piston block 64: is the adjusting plate 66 perforated at its forward and rear ends for the passage of the adjusting screws 67. The piston block and the adjusting plate are provided with a plurality of pas{ sages as will be later stated. The bed ot' the press is provided with an opening 68 connected by a pipe 69 to a valve .which will be later described, whereby water may be al- I lowed to enter the cylinder to force the piston up or be allowed to escape from the ryl inder to permit the downward movement of the cylinder. The buck-head and thepiston block both carry platens '70 and 71 constructed as will be now described.

The lower platen 7 O is illustrated in detail in Fig. 6, and comprises a bottom. plate 72 and a top plate 73. The top plate is formed with a central screw-threaded hub 74 which screws into a central opening in the plate 72,

and this hub is bored entirely through the plate and the upper face of the plate is formed with a counterbore 7 5 wherein is disposed a plug 76 having an overhung annular 'ange 77 and a central pin 78, which is rounded and forms the pin whereby the guide or matrix is centered on this die plate or platen and whereby the upper die plate and die are centered with relation to the approximately concentric grooves 82 forming circulating coils arranged as illustrated in Fig. 4, the open sides of'these grooves being closed by the plates 72. Preferably there are two series of these grooves, both merging into each other at the center of the disk and ending at diametrically opposite portions of the platen.

- Adjacent the center of the platen there is a passage 83 with which brth series of grooves connect, this passage '88 being connected to an outlet duct or pipe and at diametrically opposite portions of the platen and communicating each with one of the series of grooves-are inlet passages 84 and 85, each connected toga source of water and to a source of steam, the entrance of steam and 12s the entrance of water'being controlled by a valve which will be later described. By this means, either steam may be allowed to travel through the concentric channels, or 'cold water may be allot led "to travel through the channels to thus intermittently heat the platen or chill it.

For the purpose of holding a die or matrix upon the upper face of the plate 73, I form upon the upper Iace of the plate an annular .recess 86, the innerwall of which is screwt-hreaded and I provide a ring 87, which has screw-threads to engage with the screwthreads ont-he inner wall of the recess, this ring being formed with an overhanging flange 88 corresponding to the overhanging flange 77 on the plug 76 and the die or matrix is disposed beneath this overhanging flange S8 and held in place by the ring or by the plug. By removing the plug and.- by removing the ring, the matrix may be readily removed. The ring is formed with openings whereby a wrench may be applied thereto and is preferably held from any unscrewing action by means of a set screw 89. v

The upper platen is constructed in the same manner as the lower platen except that a plug 76 is provided which extends entirely through the upper platen and has screw-threaded engagement therewith and is formed with a central opening to receivethe pin 7 8 on the lower platen.

For the purpose of controlling the flow of steam and cold water to the die plates, I provide the'stcam and water controlling valve (Fig. 8) which is designated generally 90 and is mounted upon one side of the bed of the press. The valve casing is constructed to provide two inlet chambers 91 and 92, the chamber 91 being for the inlet of steam and the chamber 92 being for the inletof cold water and these chambers being connected by pipes 93 and '91 to suitable sources of steam and water respectively. Disposed in these chambers are the valves 95,

.0ne valve in each chamber, each valve being provided at its bottom with a. beveled flange or head 96, which engages with a shoulder 97 at the upper end of the corresponding chamber; this shoulder form-- ing a seat. The bodies of the valves are formed with ribs 98 whereby the valves are centered properly within the chambers. Each valve is provided with an upwardly extending stem 99, which passcs upward through the valve body and through. a stuffing box 100 in the upper cud-of the valve bod D isposed above the chambers 91 and 92 are thc outlet chambers 101 and 102. These chambers both connect to a-manit'old 103,

this manifold being connected by pipes 104' and 105 to the inlet openings 81 and 85 ot' the platens. Thus. steam may pass to both of said inlet openings or cold watcr may pass to both of said inlet openings. depending upon the positions of the valves 9.) within the rcspcctivc chambcrs 91 and 91b The pan ticular construction of this manifold and its connections will bc later described. Ex-

tending downward from the" chambers 91 and 92 arc'the bonncts or hoods 106, which are provided with stuffing boxes at their. lower ends and are intcriorly screw-threaded at their lower ends and in the lower end of each hood there is disposed an adjusting screw 10?, which has swiveled engagement with n plunger 108 and disposed within each chamber 91 and 9;! is a cap 109 having an upwardly projecting boss which bears against the under face of the corresponding valve 95. this cup fitting over a coiled compression spring 110 which is disposcd within the cap and the plunger 108. it will thus be seen that the springs hold the valves to their respective seats or urge them toward these seats and that the pressure ot' the springs may be adjusted. The adjusting screw 10? is held in its adjusted position by means of the jam nut 111.

The side of the valve casing 90 is provided with a bracket 112 whereby it may be.

attached to the bed of the press and the upper end of the valve casing is provided with an upwardly projecting pedestal 113. A rocker arm 114 having oppositely disposed parallel legs is rotatably mounted upon this .the pedestal and that therefore when the rocker arm 11-1 is in onc position, one valve 9h will be depressed while the other will be raised and vice versa. The inner end of the rocker arm is pivolally connected by means of a bolt 119 to the piston block, as illustrated in Fig. l. Globe valves 120 are provided for primarily controlling the passage of water or steam to the respective valve chambers and when thc nmchinc is entirely outof operation. these globe valves are turned to cut oh the supply of steam.

Normally. and when the piston' block 1 is in its lowcrcd position. communication will be cslublishtd bctwccn the steam inlct cbambcr 91 and the platens on the buck-head and on the piston block, so that both of said platens and the dies attached thcrcto will'bc reeonoe tor will he cut The piston block is proa Li ' with.

vided -with limiting bolts 22 which are attaehed to the piston block and pass through the passages 21, these bolts being provided at their lower ends with heads, which constitute stops limiting the too great upward movement of the piston and preventing; the

detachment of the piston block and piston from the cylinder. By removing these heads, of course, the piston block and piston may be removed. v

By reference to Fig. 6, it will be seen that the outlet. passages 84 and 85 of each platen are screw-threaded and that pipes 1:22 are connected to these screw-threaded openings, these pipes extending outward to a suitable header, or manifold, this header being connected ,hy flexible pipes to the steam water inlets If do not wish to limit myself, however, to any particular arrangement of the headers and pipes connecting the valves to the platens. Each of the platens has a central water passage 83, which connects to an outlet pipe wherehy the cold water or the exhaust steam may be withdrawn whenever desir The admission of water to the cylinder oelow the piston is controlled by means the double valve 124 which may he of any or us ll construction so that when "e is shifted in one direction, the wel ie'cnt. oil but allowed to pass again when the valve is shifted in the opposite direction.

llhe manifold designated 103 generally is 'illustratr-zd in Fig, 3, and this manifold is supported by a bracket at the hack of the press The borlv of the manifold is vltormetl with a water inlet 125 and a steam inlet 121) disposed at the same level. From the water inlet ilfiliextends a passage 127, which opens into transverse passage 128, which at its ends ogsens into superimprsed valve chainhers 12%), in which are disposed the check valves 130. From these valve chambers e7ttend the outlet passages 31. The steam inet is provided with a passage 132 extending ly in the passage 12? and opening "into the transverse passage 183 extending henesth the valve chambers 7.34, in which are disprr ch 'a lves These valve chain. s lS l municate by passage we chambers Ln each of the outlet passages w mean coni'iection l wl'dvh "hle pipes it dead extend to the Now it will be tones, water is to flow through the controlling valve, the water will enter the .inl 125, thence pass into the E28 and hit the check valves 1%. 'lhis'will not only till the passages 136 but it will force down the check valves 135 and therefore the water will flow out thror'igh the Siamese connections to the upper and lower platens. When, however, the controlling valve is shifted so as to permit steam to enter, the steam will enter the Water pipe while water is passing,

through the check valves 129 and check valves 134 are provided for the purpose of preventing the water from backing up by way of the steam pipes.

The operation of this invention will be readily understood from. what has gone be fore. Normally of course the valves 120 are closed but when it is desired to operate the press, the proper dies are disposed upon the platens and held in position thereon by screwing down the rings 87 and the plugs 76 and 76, Theme tablet of the composition ordinarily used in forming phonographic tablets is placed between the (lies and the huckhead is drawn downward by hand against the force of the counterweight and locked by shifting" the lever 43 as heretofore described. Water is then admitted beneath the piston in the usual manner andthe piston rises and as it does so the steam which has been circulating through the platens is cut off and cold water is allowed to flow through the platens, thus chilling the dies. After a suitable interval, the foot lever 59 is depressed, thus releasingthe latches i? and then by shifting thelever 43 rearward the locking yolres are carried into a position beneath the standards and the counterweight causes the buck-head to rise to its normal pohead and for the piston block that the buck-head and the upper platen and the piston block and the lower platen are held in proper registering relation with each other, sothat a perfect concentricit v of the record on both sides of the 1 the piston to shift laterally as it, and cmert s more and more from the cylinder. As before stated, it is impossible for the hurls-head to lull aethere is no terniencjl; oi

cidcntally and because of the fact thatthe co-unterweig l unified. Vlou'nward and inward, there is no chance oi an operator get tin caught between the descending and rel ut-iveiy heavy couuterweig'ht and the floor which would he the case did an counterblot is secured and weight depend by gravity from the arm 27. In this case, the counterweight would fall directly downward and outward of the base. These machines in actual use are placed relatively close together, one behind the other of course, just suflicient to permit a certain turning movement of the yokes as the buckhead rises. These uprights are about 4" wide while the spaces between the uprights are approximately (3 wide. It will further be noted that control of the cold water and steam is not left to the operator who might otherwise keep the steam on too longer keep the cold water on too long, but that the steam is cut off exactly at the same point under all circumstances and the cold water allowed to flow for the same period under all circumstances. This period, during which the cold water and steam may be allowed to flow, maybe readily adjusted by adjusting the point of pivotal connection of the arm 114 to the piston block or by adjusting the screws 117. Thus the screws may be so turned that they will not engage with the outer ends of the valve rods or stems untilafter the rocker arm 114i is moved a certain predetermined distance or they may be engaged immediately and these screws may further be located so as .to tak up any lost motion.

Preferably, as will benoted from Fig. '10,

. the upper faces of the piston block is armed with a gutter 137 which acts as an overflow gutter and has a channel leading oil to the side face of the piston block.
