UNITED STATES PATENT OFFICE.

BEN CLIFFORD BLACKMON, OF DALLAS, TEXAS.

The present invention relates to a machine for assisting a Workman 1n the construction of matrices used in newspapers.

.A matrix consists of a heavy base, two thinner pieces or sheets, and three sheets of tissue, pasted together. One man, in the ordinary method of making matrices stands at each end of a small table. One man arranges the sheets while the other spreads the paste between the sheets and rolls out each sheet as it is applied to the base sheet. The principal object of the present invention is to do away with the man now necessary to arrange the sheets and to allow one man to make a matrix in less time than by the ordinary method outlined above.

Another important object of the invention is the construction ofa machine of this nature so that the same will be exceedingly simple, strong, durable, easy to manipulate, efficient and reliable in its operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing 2- Figure 1 is a top plan View of the machine embodying the features of my invention.

Figure 2 is a side elevation thereof.

Figure 3 is a front elevation thereof, and

Figure a is an enlarged detail vertical section through the forward portion of the movable truck. 1

Referring to the drawing in detail it will be seen that numerals 5 designate the four legs of the machine which are preferably mounted on casters 6, and are braced by a rectangular frame 7, or in any other suitable manner. A frame 8 is supported at the upper ends of the legs 5 and has mounted thereon a sheet metal top 9. A pair of inclined arms 10 project forwardly from the frame 8 below the top 9, for the purpose of supporting a roller 11 in a handy position as will be more apparent as the description proceeds. A pair of beams 12 are attached to the legs 5 and extend rearwardly therefrom and are inclined upwardly. Tracks 13 are mounted on the upper edges of these Application filed October 12, 1925.

beams 12. One beam is located to each side of the machine. Stops 14 are attached to the beams 12 and extend above the tracks 13 between the legs 5, as is shown to advantage in Figure 2. A pair of posts 15 rise from the beams 12 to the rear of the rear legs 5, and support at their upper ends a shelf 16 which is inclined forwardly and downwardly. A truck 17 is supported on

legs

18 and 19. The legs 18 are at the rear of the truck and are slightly longer than the legs 19 so that the truck 17 is inclined forwardly and downwardly. Grooved wheels 20 are journaled at the lower ends of the

legs

18 and 19 for riding on the tracks 13. A back 21 rises from the rear edge of the truck 17 and brackets 22 project forwardly therefrom for receiving screws 24 for clamping plate 25 on the truck 17. Brackets 26 project forwardly from the truck and have journaled therebetween a roller 27 Frames 28 rise from. the forward end of the truck 17 and slidably support journal blocks 29 in which is journaled a. roller 30. Brackets 31 are disposed forwardly of the front legs 19, and rise above the plate 9. A catch 33 is pivoted as at 34 to one beam 12, and is adapted to engage one of the forward legs 19 for holding the truck in its rearward position as shown in Figure 2. A link 35 is pivotally engaged. with the catch 33 and with atreadle 36 pivoted in the frame 7. When the operator steps on the treadle 36, the catch 33 is released, thereby allowing the truck to roll forwardly on the inclined tracks 13 until the front rollers 20 engage the stops 1 1. A shelf 37 extends from the right hand side of the machine and is adapted to support a paste pot 38. A drain lip 39 inclines downwardly from the right hand edge of the top 9 over the pot 38.

In using the machine, only one worker is required. The heavy base sheets are laid out on the shelf 16 at the top of the machine. The thin sheets are placed on the truck 17. One of the heavy base sheets is taken from the shelf 16 by the workman and placed on the top 9. The paste is applied to this sheet. The treadle 36 is then operated for releasing the truck 17 which moves forwardly. The operator then removes one of the thin sheets from the truck between the

rollers

30 and 27, and places the forward edge thereof evenly with the forward edge of the pasted base sheets. The roller 11 is then brought into play being lifted from the arms 10 and rolled rearwardly. As this roller moves rearwardly it engages the bracket 31 and pushes the truck 1'? to its rear position, the

catch 31 engaging it in this rear position as is obvious. The second thin sheet is placed on the first thin sheet in a similar manner as will be obvious. The workman then removes the remainingthin sheets from the truclr and places in place of them the tissue sheets, and these tissuesheets are applied by the same operations as described incident to the thin sheets, By actual experience it has been found that one man can make the matriceswitli this machine much more rapidly and etficiently than can two workmen using the ordinary method mentioned above.

It is thought that the construction, opera tion,"and advantages of the invention will now be apparent without a more detailed description thereof. The present embodiment of the invention has been disclosed merely byway of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that this embodiment of the invention possesses superior compactness and convenience both from the standpoint of structure and operation. It will be apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may he resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
