APPARATUS FOR DRYING MATRICES.

To all whom it may concern:

Be it known that ll, HENRY A. rsE Woon, a citizen of the United States, residing at New York,y in the county of New York and `State of New York, `have invented a new and useful Apparatus for Drying Matrices, of which the following is a specification. e l

This 'is a division `of my application tor patent SerialY No; 610,234, tiled February 23 1911.

This invention relates to the dryin of stereotype matrices. The principal ob]eets ot the invention are to provide an apparatus for drying such matrlces in a continuous uninterrupted operation by the employment of mechanism moving withthe matrices so as to make the operation short and exact, thereby uniformly drying the matrices and saving much space and time in the operation; to provide moving means whereby the necessary pressure can be applied to the drying blankets in a uni orm manner throughout the, drying operation; and to provi e means whereby the friction between the blankets and the pressing means can be reduced so as to prevent the creepingof the blankets and matrix.

Further objects and advantages of the invention will appear hereinafter.

'Reference is to be had to the accompanying` drawings in which igure 1 is a side elevation of a machine embodying one form .of this invention;

has a plane surface vals for engaging the pins and moving the forms along the table. The endless chains are shown as driven by a motor 15, shaft 16, worm 17, and worm wheel 18 on a shaft 19 on which two of the sprocket wheels 20 are located. The details of the driving mechanism are not shown herein. An desired kind of mechanism can be emp oyed for driving the chains either continuously or intermittently as desired.

In this form of the invention a second pair of chains 35 are 4employed driven in anv desired way. and having thereon pressure plates 36. The two chains are spaced and driven so that the 1ressure plates will be advanced with the forms as they are r moved forward by the hooks 14:. In the use of the device the forms are placed at one end of the table as they are received read for drying. rlhe blankets can be laid on t e forms by hand before'or after they are placed on the table.- The endless chains the hooks `111 thereon will engage the pins 12 and move the forms along.` As the forms regress, they are thoroughly heated from below and' the moisture is driven from the matrices into the blankets which are under pressure on account ofthe position vont the upper chain. It is to be observed "that the pressure exerted on the blankets and matrix will be substantially uniform throughout the heating operation. The `chains leave the forms on the other end of the table, from which they can be removed at will.

l'lihe blankets are plates by means of clamps 37 shown in Fi s. 3 and et. d y

rFliese clamps are operate an eccentric shaft 38 and an operatlng arm 39 thereon. This shaft has attached to the pressure holes 44 for the reception of the end of a rod for turning the shaft.

In this case the pressure is obtained by means of a fixed bar 40 having a springpressed shoe 41 thereon, in contact with the pressure plates as they are moved along. The compression of the springs 42 tends to press the blankets into the matrix. The shoe 41 is held in lace by headed studs 43 which connect it with the stationary bar 40 and prevent its falling too low to engage the tops of the pressure plates as they are moved around. These traveling ressure plates also prevent the matrix and lankets from creeping. A

In the form shown in Figs. 5, 6 and 7, similar conditions prevail as in Fig. 1, but in this case the creeping of the blankets and matrix is prevented and the friction reduced by theuse of an endless belt 45 which runs between the lixed'shoe 46 and the pressure plates 47 which are located above the matrices. These pressure plates are supported by springs 48 from plates 49 that rest directly on the blankets. Theyare held in position and their upward motion limited by headed studs 50.

It will be seen that in all the forms shown the matrices can be dried quickly and uniformly under a perfectly uniform pressure and that the devices for reducing friction while not absolutely necessary add greatly to the e'ficiencyfof the device.

While I have illustrated and described only two forms in which the invention can be embodied, I am aware of the fact that the drawings do not exhaust all the ways in which the invention can be carried out and therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is 1. In a device for drying matrices, the combination of a heating table having a plane surface for receivingthe forms, and a shoe located adjacent to saidsurface and having means for engaging the blankets, saidshoe being yieldingly pressed'toward the surface of the table.

2. In a device for drying'matrices, the combination of a heating table having a plane surface for receiving the forms, and a shoe located adjacent to said surface and substantially parallel having a finished sui'- face on the side toward the table'.

3. In a device for drying matrices, the combination of a heating table having a plane surface for receiving the forms, a

shoe located adjacent to said surface and' substantially parallel therewith, and a movable member adapted to trave] along the pressing surface of the shoe at the same rate as the' form travels along the table to reduce the friction.

' 4. a device for drying matrices, the

face for receiving the forms, a shoe located adjacent to said .surface and substantially parallel therewith, a pressure transmitting plate adapted to rest on the blankets for receiving the pressure from said shoe having a portion adapted to yield in a direction norl mal to the surface of said shoe, and a traveling member between the shoe and said plate for reducing the friction.

6. In a device of the character described,

vthe combination of a heating table, a shoe spaced therefrom for holding a form thereon, and resilient means for transmitting pressure from the shoe to the form.

7. In a device of the character described, the combination with a form for holdin a matrix and drying blankets, of a p ate adapted to rest on said 'blankets and having means for holding it in position, and a plate yieldingly supported thereon.

8. In a device of the character described, the combination of a/ form for holding a matrix and drying blankets, of a plate adapted to rest on the said blankets and having means for holding it in position, a plate yieldingly supported thereon, and

means for limiting the upward motion of the last named plate.

9. The method of drying a matrix which consists in placing it on a form, moving the form along a heated surface, and simultaneously applying pressure to the matrix during its travel.

10. In a drying device the combination of a heated table foi supporting an article to be dried, with a traveling member supporting and carryin a pressure plate, said member being mova le into a position to bring the pressure plate into contact with an article on the table and to move it along the table therewith.

11. In a drying device the combinatipn with a-heated table for supporting a series of articles to be dried, of an endless traveling member having a strand above the table a plurality of pressure plates carried by said traveling member, whereby they will be moved by the member into contact with the articles on the table, and means for moving the articles along the table with the pressure plates.

12. In a drying device, the combination teem? with e heated to'ble for supporting articles to be dried, of means for moving the articles thereelong, e fixed member spaced from the table,v a shoe below seid member, heeded studs for supporting the shoe t heref1f1n,l
