GRAVITY COOLING DEVICE FOR STEREOTYPE-PLATES.

Specification of Letters Patent.

Patented Aug. 1?, i915 original application filed August 9,1906, Serial No. 329,833. Divided and this application filed October 2 1913. Serial No. 792,984.

To all trimmit may concern Be it known that I, HENRY 'A. VVISE IVooD, a citizen of the United States, residing at New York, in the county of New York and have to be cooled sectional State of New York. have invented a new and useful Gravity Cooling Device for Stereotype-Plates, of which the following is av specification.

This invention relates to improvements in machines forcooling and. drying stereotype plates in which the latter are fed partially or wholly by gravity down an inclined plane while various operations are performed.

In a previous application for patent on a Machine for finishing and cooling stereotype plates, filed April 6, 1906, Serial No. 310,343. I have described an invention on which this is an improvement.

The principal objects of this improvement are to provide means for commencing the cooling operation at an earlier period and carrying it on continuously; to provide more efiicient means for rapidly cooling the plate;

to o'rovide for removing the free water from boti the inside and outside of the plate in such a manner as to leave the printing surface in a condition sutliciently dry for immediate attachment to the press; and to generally improve and simplify the construction of machines of this type. i

It is to be understood that while I have illustrated and described an embodiment of the invention in which it is employed for use upon stereotype plates and While that is the principal use to which I at present contemplate putting it, yet the principles in volved are applicable for operation upon other kinds of castings and articles which or dried.

Reference is to be had to the accompanying three sheets of drawings in which, Figure 1 is a side elevation of a machine illustrating one embodiment of my invention: Fig. 2 is a side elevation of a portion of the same on an enlarged scale, parts appearing in section: Fig. 3 is a fragmentary plan of a portion of the same: Fig. 4 is a view on the line 4-4 of Fig. 3: and, Fig. 5 is a sectional view on the line 5-5 of Fig. 3.

In a machine of this type, a. frame a'is provided having an inclined body or runway a for supporting and carrying stereotype plates or the like. The machine is intended to be used in conjunction with an arch 0 in which their interior surfaces are shaved- 'From this point they pass to a cooler fl and from that they move out on a table 6 from which they are removed by hand or otherwise.

In the present case, in addition to the gen-' eral features indicated by the reference letters. the machine is provided with a drying device f adapted to remove the free water from the surfaces of the plate after it passes through the cooler and in addition to this, the arch c, in which the. shaving is performed, is provided with means for preliminarily cooling the plates while they are being shaved so as to commence the cooling earlier and thus insure the desired drop in temperature by the time the plates reach the drying device. These features and other principles-which I have employed for the purpose of improving the type of gravity shaving machine represented in the above mentioned application, will now be described by reference to the construction which is illustrated in the drawings. 7

The main shaft. 31 carries av worm 38 which operates a worm-wheel 39 on a shaft 26. Arranged on this shaft is a shaving blade 40 located in the arch c. The plate descends along the inclined table into this arch and is stopped in proper position therein by means of mechanism operated from the shaft 26. IVhile the plate is in the arch c, it is intended to be cooled fcnultaneously with the shaving operation. For this purpose the arch is hollow or has a channel 68, as shown in Fig. 2, this being provided with a supply pipe 69 at one end and a discharge r of the stereotype plate and their edges meet drying device.

When the plate reaches pipe at the other.

the arch d, it is the proper position in stopped by a gate 21*. vided to prevent spattering of water the cooler on the machine.

In the upper part of the arch d is a pipe 72 which preferably receives water from the pipe 70 and which is provided with perforations for directing the water on the top "of the stereotype plate while the latter is in the arch. In order to provide conveniently for this pipe, the arch has a channel 73 in the upper part thereof in which the pipe is located. Lower down in thearch is a plate "M-of a shapesimilar to that of the stereofrom type plate and located in such position that the plate passes over it. This plate 74: also has-a cavity 75 in which is located a pipe 76 having erforations for directing the water there om against the under side of the'stereotype plate. The pipe 7 6 receives water from the pipe 70. It will be seen that the water forced against the plate on both sides will run down the same into a trough 7 7 located below from which it discharges through a pipe 78. A second. splash guard 79 is located vbelow the arch d.- Whenthe cooling operation is completed, the cam for operating the stop 21 moves into such position that the gate is withdrawn andtheplate is allowed to feed along This drying device comprises a frame 80 having a series of adjustable bearings 81 supported bys rings 82 and adjusted by thumb nuts 83. ach bearings supports a roller 84 covered by, ab sorbent gauze or other absorbent material. These rollers are cross-section that their outer surfaces form the arc of a circle of the same radius as that so that the entire surface of the plate is operated upon by therollers to remove the free water therefrom, which otherwise would damage the inking rollers of the press. The frame 80 is movably mounted on the main frame a-so that the whole device can quickly removed bodily for the purpose of replacing the rollerswith. dry ones to insure nearly perfect action. 1 v

For the purpose of brushing the moisture and incidental metal shavings from the interior of the plate, the shaft 26 is provided with an arm 85 havinga pin 86f which rotates with it. On a shaft 87 placed somewhat eccentric with respect to shaft 26 is an arm 88 having a slot 89in which the pin 86 operates. Such a connection is required because of the eccentric relation of the shafts." Adjustably mountedwith respect to brush:

the arm 88 is a frame 90 carrying a 91, extending the length of the; stereotype plate, adapted to be turned by the rotation of the shaft 26 .so as to cleananddrythe interior surfaces of the plates.

I i-J6 fIn a machine for coolin cast plates, [the combination of means go plates, means for directin passes under the outside drying device, it .moves to a position abovethe table over the drying and cleaning brush and can be removed therefrom by hand or forced from the position over the brush by the descent by gravity. By the employment of the principles illustrated above, whether in the form shown or in any other form embodying these principles,it willbe seen that the stereotype plates are fed along the machine in'a most effective and inexpensive manner by gravity; that the plates are cooled in a most effective manner by direct contact with water and are finally wiped and dried both on the inside and on the outside, hnd that the machine is "improved and simplified in manyparticulars. While I have shown and described a particular form in which I at present prefer to embody my invention, I am aware of the fact that many changes can be made therein by any person skilled in the art without departing fromthe principles of my invention limited to the particular mechanism illustrated and described, but

What Ido claim and desire-to secure by Letters-Patenet is for finishing and cooling cast plates, the combination of a cooling arch through whichthe plates pass, and a stationary splash plate located on each side of the cooling arch. 2.
