Application filed March 9, 1891' $erial1lo. 384,355. (No model.)

In the accompanying drawings, Figure 1 is a plan or top view of a press embodying my improvement. Fig. 2, is a side view of the same. Fig. 3, is an irregular longitudinal section, taken, as indicated, by the line :0 00, Fig. 1, certain parts of the machine being entirely omitted. Fig. 4, is a longitudinal section, taken at the plane of the dotted line 0c 2, Fig. 1, certain parts of the machine being entirely omitted. Fig. 5, is an irregular longitudinal V section, taken, as indicated, by the line a: y,

Fig. 1, certain parts of the machine being e11- tirely omitted. Fig. 6, is a transverse vertical section of certain parts of the machine looking in the direction indicated by the arrow 1, marked adjacent to Fig. 1. Fig. 7, is a vertical section of certain parts, taken lengthwise of the machine. Fig. 8,v is a vertical section of certain parts, taken length wise of the machine; and Fig. 9, is a vertical section of certain parts, taken lengthwise of the machine. Figs. 7, 8 and 9, are made on an enlarged scale.

Similar letters and numerals of reference designate corresponding parts in all the figures.

The frame-work of the machine may be of any suitable construction. As here shown, it consists, essentially, of two side pieces united by stretchers and surmounted by a bed A. The shaping of the material is performed by means of a body section or mold plate B,and two plungers, end sections or formers 0 O In the present instance there are two of the body sections or mold plates, and two pairs of plungers, end sections or formers; the press being organized for shaping two cakes or quantities of material at the same time. Obviously, the number of body sections or mold plates, and plungers, end sections or formers is immaterial, so far as the principle of my improvement is concerned. As here shown, the body sections or mold plates are formed in one integral structure. They are secured to the bed A by screws or otherwise. Each,in the present instance, has combined with it a feed box O, which is open at the top and at the outer side.

The material to be shaped is introduced into the feed box, and from there carried into the adjacent body section or mold plate by means of a plunger, end section or former C The material may beintroduced through the opening in the top of the feed box, or through the opening in the outer side thereof. Preferably there will be combined with each feed box an automatic feeding mechanism for introducin g the material through the side opening of the feed box. I have shown such a feeding mechanism, and it will be best understood by reference to Fig. 6. It comprises a carrier D, reciprocating transversely to the length of the machine in guides d'd which are coincident with the side opening of each feed box. The guide d is adjustable toward and from the opposite guide d owing to the fact that it is secured in place by screws passing through slots formed lengthwise of the machine in lugs extending from said guide d. This adjustability is to suit different sized cakes or quantities of material. The outer end of each carrier D is pivotally connected to links d which are also pivotally connected to the upper end of an oscillating arm (1 Each arm (1 is mounted upon the stud 01 and is provided with an arm 01 extending at an angle to it and receiving in its end portion a Vertical pin (V. The upper end of the pin 01 extends through an arm 61 which rests upon a Washer d arranged above a spring 01 which is coiled around the pin (Z and at the lower end is sustained by the arm 01 Each arm 01 is rigidly fastened to a rock shaft d, extending transversely to the length of the machine and journaled in bearings supported in the frame of the machine. The rock shaft d has affixed to it an upwardly extending arm (Z held against a cam (Z by means of a spring material.

d extending from the bed A down to the arm 01 and drawing this arm upward so as to move and hold the arm 01 against the cam. When the cam oscillates the arm d against the resistance of the springs d the arm (i will press downwardly upon the spring (1 and the latter, by exerting a down ward press- 1116 upon the armed, will oscillate the arm (1 toward the center of the machine, thereby moving the carriers along the guide-ways formed between the guides cl (1 for the purpose of propelling the cakes or quantities of material into the feed box 0. When the cam d moves in such a direction as to allow the spring c2 to produce a reverse movement of the armd the carriers D will be moved outwardly so as to permit other cakes or quantities of material to be introduced into the guide-ways in front of the carriers.

For the sake of clearness, I have marked the cakes of material with the letter F, wherever they appear.

The plungers, end sections or formers C are fastened to a cross-head (3 reciprocating along ways 0 lengthwise of the machine. During the reciprocating movement which they have they enter the body sections or mold plates, and afterward recede from the same. They are not, as here shown, rigidly connected with the cross-head 0", but have their shanks fitted into sockets formed in the cross-head in the direction of the length of the machine, so that the extremities of the shanks will protrude beyond the cross-head and impinge against aspring 0 This spring may be fastened to the cross-head by ascrew 0. By thus combiningthe shanks of these plungers, end sections or formers with the cross-head they will be capable of yielding slightly when coacting with the other plungers, end sections or formers C to press the Keys 0 extending into slots in the cross-head and also into slots formed in the shanks of the plungers, end sections or formers O, to prevent the latter from turning are provided. The cross-head C is at its ends fastened to rods 0 which are also fastened to across-piece 0 Frames 0 severally consisting of

upright pieces

2, 3, rods 4:, and shanks 5, 6, extending from said

upright pieces

2, 8, and working in bearings 7, on the bed plate A, are connected to the cross-piece 0 As here shown, the connection is made by rods 8, extending from the shanks 6 through the cross-piece O and fastened to the latter by means of nuts arranged on opposite sides of it and engaging with screw threads formed on said rods 8.

The frames 0 have rollers 9 journaled in their upright pieces 3 to coact with cams C affixed to the shaft E. These cams acting upon the frames 0 move the cross-piece (J rods 0 and cross-head O in such direction as to cause the plungers, end sections or formers O to enter the body sections or mold plates B. The reverse movement of these plungers, end sections or formers is produced by means of springs 0 fastened to the bed A, or an appurtenance thereof, and also to the cross-piece C". The connection with the crosspiece 0 will preferably be made adjustable, as, for instance, by means of screw bolts 0 passing through said cross-piece and having nuts applied to them on opposite sides of the crosspiece. The movement produced by these springs 0 will be limited by means of lugs 0 extending upwardly from the bed A, and coacting with projections 0 upon the rods 8, for this purpose. These projections Wlll preferably be constructed of or comprised of soft material, such as disks of leather, in order that the motion of the parts produced by the springs G will not be arrested too suddenly.

The plungers, end sections or formers C are attached to a frame 0 which is fitted to slide-ways c c fastened to the bed A. Pref erably the shanks of these plungers, end sections or formers will be longitudinally slotted and fastened by screws 0 to the frame C so as to be capable of adjustment relatively to the latter. The adjustment may be effected by screws 0 extending through tapped holes in portions of the frame 0 in rear of the shanks of said plungers, end sections or formers and impinging against the ends of said shanks. 1

The frame 0 is provided with a roller 0 which bears against a cam O affixed to the shaft E. By means ofthis cam the frame will be moved in a direction to move the plungers, end sections or formers O away from the body sections or mold plates B. The frame 0 is also provided with a roller 0 which coacts with a cam C affixed to said shaft E. This cam moves the frame C in such direction as to cause the plungers, end sections or formers C to enter the body sections or mold plates B.

As represented, the material to be pressed will be introduced into the feed boxes after being already formed into cakes, and will be pressed for the purpose of giving it its final shape. The faces of the plungers, end sections or formers may be ornamented to produce any ornamental surface on opposlte sides of the cakes, and to imprint or delineate letters thereon, if this is desirable. After the pressing within the body sections or mold plates the cake"will be carried by the plungers, end sections or formers C entirely through the body sections or mold plates. The cakes will then drop through a hole a. formed in the bed A, onto any part designed to receive them. In the present instance a carrier Gr is arranged beneath this hold in the bed, and, as here shown, consists of an endless band passing around pulleys f f said band running in the direction indicated by the arrow marked upon it in Fig. 1. The cakes after being carried away by the band may be removed from it in any suitable way, as, for instance, by hand. The roller f is journaled in'a bracket A, which may be fastened to the floor. The roller f 2 is affixed to a shaft F, which is journaled in a bracket a depending from the bed A, and a bracket (1 affixed to one of the side pieces of the machine frame. The shaft F has affixed toit a bevel gear wheel f 3 which meshes with the gear wheel h affixed to an upright shaft which is journaled in the bracket a and has'affixed to itsupper end a bevel gear wheel h. The bevel gear wheel it engages with a bevel gear wheel 6 affixed to the shaft E. By this train of wheels motion is transmitted from the shaft E to the shaft F. The shaft E is driven from the main shaft I of the machine through a pinion 'i mounted on this shaft and engag: ing with a gear wheel 6' affixed to the shaft E. Gas or air is employed in this machine for the purpose of facilitating the detachment of the cakes of pressed material from the plungers, end sections or formers C 0 The plungers, end sections or formers O C are constructed in essentially the same manner; hence the construction of both sets may be understood from Fig. 9, which illustrates one of the plungers, end sections or formers C. It will be seen that a gas chamber 0 is formed in the rear portion of this plunger, end section or former, and that a passage 0 extends horizontally from such gas chamber to the operative face of the plunger, end section or former. This passage is enlarged at the operative end of the plunger, end section or former to accommodate a valve or ejector c. From the latter extends rearwa'rdly through the passage 0 a rod 0 which is provided within the gas chamber 0 with a valve 0 The space between the valve or ejector 0 and the valve 0 is greater than the distance between the gas chamber 0 and the enlarged portion of the passage 0 which constitutes a seat for the valve or ejector e hence when the valve or ejector 0 is seated so as to close the passage 0 the valve 0 will be moved away from the passage 0 and conversely when the valve 0 closes against the end of the passage 0 the valve or ejector 0 will be moved away from its seat. By means of this combination of parts the passage of gas from the gas chamber to the faces of the cake of pressed material which are in contact with the operative faces of the plungers, end sections or formers O C may be controlled. The gas used will preferably be compressed air, and will be conducted to the plungers, end sections or formers O O by pipes 0 of flexible material, such as india rubber, leading from a valve box (1 These pipes 0 communicate with the upper parts of the plungers, end sections or formers C but communicate with the shanks of the plungers, end sections or formers O and communicate with the gas chambers of the latter by horizontal passages in their shanks. The valve box (3 communicates through a pipe 0 with a container or reservoir 0 of gas.

The valve box 0 has two rotary valves 0 fitted to it. Each has a single port which may be brought into line with a port 0 communicating with a pipe 0 and communicating with a passage 0 which receives gas from the pipe 0 When these valves are oscillated, they either open or close the port 0 I will now describe how the valves 0 are operated. At the ends they extend through the valve box and each has extended through one of its ends a cross pin 0 A spring 0 is fastened at one end to each pin 0 and at the other end to the valve box. It oscillates each valve far enough to bring its pin 0 into contact with a stop pin When the valves are in such positions that their pins 0 rest against the stop pins 0 the valves close the ports 0, and no gas flows to the gas chambers 0 of the plungers, end sections or formers 0' O Tappets J J serve to oscillate the valves against the resistance of the spr1ngs' 0 for the purpose of opening the ports a. They are fastened to the sliding plate (3 and are so arranged that the valve controlling the admission of gas to the gas chambers of the plungers, end sections or formers C, will be opened slightly before the valve which controls the admission of gas to the other plun- -gers, end sections or formers O The gas is admitted to the gas chambers of the plungers, end sections or formers O at the instant that the latter begin to recede from the position in which they operate upon the material within the body sections or mold plates, but gas is admitted to the gas chambers of the plungers, end sections or formers 0 when they eject the material from the body sections or mold plates. After gas has been admitted to the gas chambers of the plungers, end sections or formers, it will flow through the passages 0 thereof, and as soon as the relaxation of pressure permits of the moving of the valves or ejector 0 outwardly, the latter will" be so moved by'the pressure of gas, and thereupon gas will escape from the gas chambers and detach the pressed cakes. The flow of gas will be only momentary, because the valves 0 will close the passages 0 and cut off communication between the gas chamber and the passages 0". V I

The supply of compressed air in thereservoir or container 0 is maintained by meansof a pump, K, operated by an eccentric 7c affixed to the main shaft 1. Y

In pressing some materials, it is desirable to lubricate the body sections and I will now describe means for that purpose. L designates a reservoir of liquid, which may be vinegar. It has a tubular stem which communicates with a valve box Z, and the latter communicates with the gas reservoir or container C The valve box has fitted to it an oscillating valve Z having two ports. Motion is imparted to this valve through an arm Z connected by a rod Z with an arm i moved in one direction by a cam Z mounted on the shaft E and in the other direction by a spring Z.

one point a peripheral depression'and at an-' I'IO This cam is mainly circular, but has at other point a peripheral projection. Normally'the valve will be held in such position as to close the tubular stem of the reservoir L, as well as the passage which leads to the gas reservoir or container C From the valve box Z, pipes Z Z extend to the top of the body sections or mold plates near the extremities thereof. These pipes extend horizontally from the valve box and the hollow stern of the reservoir L and the passage which leads to the gas reservoir or container 0 are V61? tical. The ports of the valve are bent so that when the valve is in one position, it may close and prevent the passage of either the lubricating contents of the reservoir or the gas in the container 0 from passing it. It may be adjusted to another position to establish communication between the gas container and one of the pipes Z or Z In addition to the ports, the valve Z has pockets Z Z. Before either set of the plungers, end sections or formers is to be lubricated, one of thesepockets will come opposite the tubular stem of the reservoir L and receive a quantity of liquid therefrom. Afterward it will be carried round to a position opposite one of the pipes Z or Z and,as at this time, communication will be established by one of the ports between this pipe Z or Z and the gas container 0 a puff of air will pass from the latter into such pipe carrying with it a spray of the liquid in a pocket. The depression in the cam Z will cause the oscillation of the valve Z into a position to effect the discharge of lubricating liquid to one end of the body sections or mold plates and the projection of the cam will adjust the valve to effect the discharge of liquid to the other end of the body sections or mold plates. It is intended that the sprays of liquid shall be applied to the faces of the plungers, end sections or formers. The cam operating the plungers, end sections or formers C is so shaped that just before the discharge of the lubricating, liquid which is intended to be supplied to the faces of these devices, the latter will be moved backward for a short distanceto expose, them to the lubricatingliquid.

The plungers, end sections or formers C have the lubricating liquid deposited upon them before they have entered the body sections or mold plates to their full extent. After receiving the liquid, they are moved still farther inward to cover the opening through which the liquid entered. I

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a press the combination with opposite plungers, end sections or formers and a body section or mold plate, of a reservoir for lubrr cating liquid, a gas container, and a valve controlling the communication ofsaid gas container with the molding devices whereby the lubricating liquid may be caused topass to said molding devices, substantially as specified.

2. The combination with a gas container and a movable end section or former, of a valve intermediate of the gas container and end section or former, a gas conduit leading from the gas container to the end section or former and within which the valve is located, and mechanism substantially such as described for automaticallyoperating said valve, substantially as specified.

3. The combination with a gas container, of end sections or formers receiving gas from said gas container, each having a gas chamber communicating with the operative end of the end section or former, valves in said end sections or formers for controlling the passage of gas and a valve between the gas container and end sections or formers operating to admit gas to one of said end sections or formers in advance of the other, substantially as specified.

4. The combination with opposite plungers, end sections or formers and a body section or mold plate, of a reservoir for lubricating liquid, a gas container, and a valve controlling the passage of lubricant to the formers, said lubricant being ejected by gas from the gas container, substantially as specified.
