Application iiled september 18, 1914; Serial No. 862,271.

particularly to enable impressions to be taken from the whole or certain lines of a printin form as may be desired.

The invention is more especially adapted for address printers of that class which embody reciprocating platens to produce impressions from the type forms, usually addresses, of printing devices which. are adapted to bear-ranged in accordance with a card index system.

It is sometimes desired to take an impression of the entire address and separate impressions of the'street and city on the second and third lines or other combinations as may be found useful. I have found this can beconveniently accomplished by providing a sectional platen with means for relatively adjusting the sections as required to project into operativeposition for obtaining the desired im- In the accompanying drawings illustrat-. ing one embodiment of the invention Figure 1 is a sectional view showing a reciprocating platen arm and platen of 'an address printer with a printing devicein printing position. Fig. 2 is a front elevation of the platen and front end of the platen arm. Fig. 3 is a sectional view on the line 3-3 ofFig. 2. Fig. 4 is an end view of the platen.

Referring to the drawings, 5 is the bed of the machine upon which the printing device 6 rests during the impression operation, these printing devices being placed in printing position by hand or automatically fed thereto from a magazine 7 in a suitable manner. The platen arm 8. is pivotally mounted at 9 on the frameof the machine and is preferably provided with a handle 10 conveniently located for deressing the platen arm. This platen arm is preferably returned to and normally held,

the name on the first line and in the elevated position shown in Fig. 1 by'a spring (not shown). l t I The platen illustrated in the drawings comprises two sections 11, 12 which are an ranged for relative movement in the head so 13 secured on the platen arm by a bolt 14 which extends through an enlarged opening 14 of said arm. The'platen 'is adjusted lengthwise by screws 15 which extend I, through the arm' and bear upon the head on as opposite sides of the bolt 14 and the platen is adjusted transversely by" a screw 1.6

which passes through the arm and bears upon a lug 16' extending rearwardly from I the head. The head has two parallel cha'n 1e nels 17 extending lengthwise thereof to commodate the sections and the latter are held in place in the channels by transversebolts 18 which pass through slots 19in the sections. Springs 20 are interposed in said.

slots between the bolts 18 and the upper ends of the slots to normally sustain the -sections in elevated position. Cam-face rods 21 are located in the upper ends iof the chan-- nels 1-7 above the sections-to operate on the so sections and depress the same when turned to proper position and for this purpose crank handles 22 are provided on the rods toworkbetween stops 23pm the end of the head. p I p l In the embodiment of the invention lected for illustration here the platen is made in two sections, one ofwh ich has aT- shaped head 11 adapted to produce an ir pression from two lines of type on the print ing device, and the other of which has an L-shaped head 12' adapted to produce an impression from one line of type on the printing de vice, but it will be readily under stood that the platen may be divided into as more sections of difierent shapes as oecasion may-require. .When it is desired to take an impression from the entire printing device the sections will be arranged with their faces flush as shown in the drawings, 190 To take an impression from, say, the first or name line. of the address the cam rod i'or. a section 11 will be adjusted to permit the springs 20 to move this section upward nutil its face 11 is above (or back from) the plane of the face 12' of the other section so that in the next operation of the platen arm the section face 12 will be carried into operative relation to the name line of the print mg device while the face 11 of the other 110 section will be held out of operative relation with the printing device. To obtain an isn iiression from the street and city lines of the printing device the cam rods will be ope ated to adjust the platen face 11' in operative relation and the platen face 12 out of operativerelation with the printing device. These adjustments can be very easily and quickly eflected without any material interruption in the speed of the machine so that successive printing operations may be performed to take an impression from thcfcntire printing device and then from parts of the printing device by properly manipulating the cam rods It will be understood, of course, that these printing devices may be provided with forms for printing other subject matter than an address and that the sections of the'platen may be arrang d-and constructed in such form and numbers to produce any combination of impressions from the printing device that may be tlesired.

l-claim:

1 In a printing machine, the combination of a support, and a platen supported thereby and bodily movable therewith, com' prising a head and a pair of parallel sections slidably mounted thereon and having, their: facesinormally located in the same plane, and means for adjusting said sections relatively and independently to move one or the other of said faces out of operative position.

2. In a printing machine, the combination of a support, and a platen supported thereby and bodily movable therewith, comprising a head having a plurality of channels therein, a platen section movably secured in each of said channels. and means for relatively adjusting said sections.

3. In a printing machine, the conibina- 1011 of a support, and a platen supported 7 thereby and bodily movable therewith, comindependent means operatively associated With said sections for moving them rela tively in and out of operative position.

4-. In a printing machine, the combination of a support, and a platen supported thereby and bodily movable therewith, comprising a head provided with a plurality of channels, a platen section mounted in each of said channels, means for normally holding said sections in position with their faces flush, and cam devices operating upon the platens for depressing one relatively to the other.

The combination of a head, a plurality of slotted platen sections movably arranged in said head, bolts passing through the wads of the head and the slots in the platen tions, springs located. in the slots between the bolts and the upper ends of said slots to normally hold the platen sections in elevated position with their faces in the same plane, and means Within the head for operating upon said platen sections to adjust said sections relatively and independently.

6. The combination of a platen arm, a platen head, a platen carricd' by said head,

a bolt loosely mounted in said head for securing said head to the arm, adjusting screws operating through the arm on the head on opposite sides of said bolt, a lug projecting rearwardly from the head, and an adjusting screw o 'ierating through the head upon said lug behind the bolt.
