T 0 all whom it may concern:

Be it known that I, HENRY A. VVIsn W'ooo, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Steam-Table, of which the following is a specification.

My invention relates to steam tables for use in drying stereotype matrices; the particular objects being to provide a steam pressure cylinder for operating the table, located beneath the plane of the type and preferably below the bed where it is out of the way; moreover; to provide the steam table with means for performing the function of, and eliminating the ordinary elevating table used in this art; to provide a loading and ejecting device in order to save the necessity of pushing the form in and pulling it out by hand; and in general, to improve the construction of devices of this character in such a manner as to save room, time, and labor during one of the most important operations in the manufacture of stereotypes.

Reference is to be had to the accompanying three sheets of drawings, in which- Figure 1 is a side elevation partly in section of a steam table showing one way in which the principles of my invention may be embodied. Fig. 2 is an end elevation of the same partly in section. Fig. 3 is a sectional view on the line 3 of Fig. 1. Fig. 4 is an elevation of a portion of a steam table showing a modification. Fig. 5 is an elevation partly in section of another form in which the invention may be embodied. Fig. (3 is. an end elevation partly in section show ing another form of the invention. Fig. 7 is a side elevation of another form of the device provided with a loading and ejecting device. Fig. 8 is an end elevation of the same. Fig. 9 is a fragmentary plan of part of the loading and ejecting device. Fig. 10 is a side elevation of the same partly in section on an enlarged scale, and Fig. 11 is a plan showing another part of the loading and ejecting device.

Referring first to Figs. 1, 2 and 3, it w1ll be seen that I have shown a frame 10 upon which is mounted a static-nary platen 11. Below this platen is arranged a bed or table 12. This table is provided with a flexible tube 13 by means of which steam or other heating fluid may be introduced into it. The table is connected by means of a rod other.

1 1 with a plunger 15. This plunger works in a power cylinder 16, supplied with steam or other fluid under pressure, through a pipe 17, this pipe in the present instance acting vboth for supply and exhaust. The cylinder is mounted in the present instance, in stationary position on the frame, and the plunger works back and forth and raises the steam table with the form thereon toward the iron tables on which the forms-are placed 1 1n the composing room, it is necessary to use lifting tables to receive the form from the iron tables and transfer it to the steam table, the lifting table being adjusted by a screw to the level of one and then to that of the In order to obviate the necessity of using such lifting tables, I have provided the steam table with an extension 19. In the form illustrated in these figures, this extension is fixed to the steam table and moves vertically with it. This extension is preferably provided with a depending rod 20 having flexible connections 21 passing over pulleys 22 to support a counter-weight 23, or it may be counterbalanced in any other way. The extension, it will be seen, is of such a nature that its upper surface is always at the same elevation as the upper surface of the steam table or bed. When the tables from the composing room are brought in, any difference in level may be avoided by simply turning a steam cock and moving the steam-table and extension up or down.

Relative motion between the bed and platen or press-head, heating of the steam. table, application of pressure and manipulation of the extension 19 can be secured in many other ways than that which I have described with reference to Figs. 1, 2 and 3. Two other forms which I have provided for accomplishing certain of these results are shown in Figs. 4 and 5. In the former, an extension 190 is shown as being ordinarily stationary, but adapted to have the same elevation as the top of the steam table when the latter is lowered to its lowest position.

In Fig. 5, I have shown an extension 191 provided with means for raising and lower ing it independently of the steam table. In this case a cylinder 25 is formed either on the frame of the machine or independently of it, and a piston 26 therein operates the extension 191 through a piston rod 27. A supply and exhaust pipe 28 is shown for the usual purpose.

Another form in which my invention can more conveniently be embodied is shown in Fig. 6. In this case the steam table is provided with a hollow plunger 150 having an opening 151 communicating with an elongated cavity 152. The cylinder 160 is provided with a steam pipe 161, and during the reciprocation of the steam table this pipe communicates constantly with the elongated cavity 152 so that steam is supplied to the interior of the steam table constantly without the use of the flexible connection which is employed in the form shown in Fig. 1. The exhaust steam and drippings from the steam table pass down through a tube 120 to the bottom of the cavity within the hollow plunger. A port 121 communicates with an elongated cavity 122 in the outside of the plunger, which in turn communicates with the exhaust pipe 162. In a manner similar to that mentioned above, this exhaust pipe is always in communication with the cavity 122, and consequently the heating of the steam table and the removal of exhaust steam therefrom can be constantly carried on. In this form, the extension 19 shown in Fig. 1, may, if desired, be employed, and it may be provided with a loading and ejecting device, but I have shown this device as applied to the form shown in Figs. 7 and S, in which the platen 110 is mounted on sliding rods 111 which are counterbalanced by springs 112 and are connected by a head 113. This head is operated by a plunger 114 in a steam cylinder 115, the table or bed being stationary.

The loading and ejecting device comprises the following elements: A rod 30 is connected with the platen and rises and falls with it. This rod is provided with a rack 31 which meshes with a pinion 32 mounted on a shaft 33. This shaft carries arms 34 which are connected with links 36. These links are provided with slots 37 at their ends for receiving a cross-rod 38. The crossrod carries a bar 39, which, as shown in Fig. 10, is preferably of triangular or trapezoidal shape and fits in a groove 40 in the extension 19, the groove being of substantially the same shape as the bar to enable the bar to drop into the groove and bring the top surface of the bar flush with the top of the extension, and to allow no small apertures into which loose type might drop. When the platen is in its highest position, the bar 39 will remain in the groove 40, but as it descends toward the table, the movement of the rod 30 will cause the links 36 to move the cross-rod 38 along the extension 19, as is indicated in dotted lines in Fig. 10.

It will be seen that the swinging of the links 36 in an upward direction at their outer ends not only tends to pull the bars 39 along the extension, but raises them out of the groove in opposition to the counterbalanced weight.

The crossbar is yieldingly connected with the links by means of a pair of springs 41 in the slots 37. The cross-rod also carries a frame 42 having a pin 43 projecting inwardly from each side toward the extension and adapted to engage a form thereon.

Stop pins 44 on the extension 19 are provided for the purpose of arresting the motion of the carriage when ithas brought the form under the platen. This device is preferably counterbalanced by a weight 45 or the like, connected by cords or other flexible connections 46 with the bar 39. These cords pass over pulleys 4-7 at the rear of the bar when it is in its extreme position. The operation of this part of the device will be readily understood. As the platen descends from its highest position, the rack 31 operates the pinion to force the carriage or frame connected with the cross-rod 38 into the press. Most of the motion of the carriage takes place before the platen is in such position as to exert any pressure. After the chase is placed in proper position on the steam table, it is of course necessary that further downward motion of the platen should take place, therefore, when the chase reaches this position and the rod is stopped by the pins 4-4, the additional motion of the links 36 will be taken up by the springs 41, the chase remaining stationary. During the compressing operation, there will, of course, be no motion of the form with respect to the steam table, and when the platen first starts back, there is sutlicient lost-motion between the ends of the chase and the pins 43, which engage it at this time, to prevent the chase from being moved before the pressure is taken off. The remaining motion of the platen in an upward direction withdraws the carriage, the pins 43 engaging the rear of the chase and ejecting it from the press.

lVhile I have illustrated and described certain forms in which my invention may be embodied, it is to be understood that many modifications may be made in each of them, and the invention can be carried out in many ways within the scope thereof as expressed in the claims. Therefore, I do not wish to be limited to any or all of the particular forms shown, but
