H. .s. MQGORMACK. TYPE WRITING MACHINE APPLICATION FILED JAN. 30, 1909v 953,793. w Patented Apr. 5, 1910.

m a i918 p 7 4 1 .25 of these drivin v screw stud 19, t e studs fixed in the ends having a hook or key 28, to fit in a groove or ports 14:, 15. These supports are substan tially' similar, and .carry corresponding parts, so that the description of one will suflice for both.

'. The roll 12, which is the main feeding roll, is pivoted by means of a stud or shoulder screw 16, which-is fastened directly to the s1de of the support 14.01 15. In contact with the roll 12 run two driving rolls 1? and-18, which run upon the surface of'the platen,- each. acting independently as a driver for the roll 12, so that positive movement of the latter is assured. The

driving rolls

17,18 are loosely mounted to accommodate themselves both to the surface of the platen and to that of the roll 12. Each rolls is pivoted upon a of aplate which between its ends is pivoted at 21 upon the free end of a lever '22, the latter pivoted at 23'to the support 15. The roll plate20 can turn about pivot 21, to enable the rolls to bear with similar pressure. upon the surface of the platen; and both rolls may move upon the arm 22 tov accommodate themselves to the feeding roll 12; the joints beingsufiiciently loose to permit firm drivin three rolls and also lietween the platen and the drivingrolls; these three rolls preferably each made of soft rubber to give them a grip on one another, and also upon the surface of the laten. v

The front drlving roll 13 is carried upon a swinging arm 24, which is pulled by a spring 25 to press .the roll 13 against the roll 12; said spring being also preferably connected to the arm 22 to hold the drive rolls upagainst the feeding roll 12; this provision being especially useful when the device is being attached to or detached from the machine. The roll 13 is made of wood or other hardniaterial, and it is formed with peripheral grooves or corrugations 26 conducing to the positive feeding of the cards these corrugations or ridges tending to crimp the cards and cause the latter to. be gripped firmly by the mam feeding roll 2. I

The support 15 is'in the form of a plate to the'side of which is secured a block 27 keyway 29 cut along the bottom of the rod 9,'which is fixed to. the platen frame. Fig.

4- shows the method by which the key 28 is inserted in the groove 29. ThQDi Q UIl-I contact between the port 15 swung forwardly to the Fig; 3 positlon, and a cramp 30 pivoted at 31 upon the bloclg 27 is swung by an-integral fingerpiece 32 to the Fig. 3'position,'the cramp bearing on the front side of the rod 9 near the groove 29 and firmly locking the support to the rod with the

guide rolls

17, 18 pressng firmlyupon the platen; this locking bemg secured by a downward pressure on the finger-piece 32 at Fig. 3,'the effect of which is to press said rolls down upon the platen at the same time that the support becomes finally locked upon the rod; so that the rolls are securely held under pressure against the platen. The block27 is very thick so as to give a broad bearing upon the r 9, and especially in the groove 29, so that there is no liability of the support becoming loose or skewed upon the rod; and-as addig tional security the cramp 30 with its fiugerpiece 32 1s pivoted in a-slot 33 which divides .the block 27 into two portions; the bearing of the cramp 3O upon the rod 9 being therefore between said points of bearing of the hook or key 28 in the groove 29. The whole produces a powerful fastening, and liability of disarrangement of the device in use is avoided.

The supports 14, 15 with their ap urtenances may be attached to the rod 9 at any point along the platen to accommodate cards or the like of different Widths; and by simply lifting either finger-piece 32, to relieve the pressure on the rod 9, the support may be slid along the rod and again secured Wherever desired.

For convenience in introducing the cards or sheets of paper, there is carried upon.

each support a highly yielding spring finger 34. which extends down between the paper shelf 5 and the introductory side of the platen, and at its lower'end bears against the platen, to direct the paper into' the bite of the platen and themain feed rolls'7 said lower end of the spring'finger bearing firmly against the platen at 35 to cooperate there with in feeding the'card or sheet to said roll. Said spring finger is preferably used in cooperation with a gage 36 for the side edge of the card or sheet, said gage 36 being formed upon an arm 37, which is pivoted at 38 upon each of the supports l-l and 15; and

the metal of the arm being bent to form a plate 39 upon which the card or sheet may rest as, itis being introducedv into the machine; the finger 34 forming a continuation of or attached to the lower end of said plate 39. These gages 36 are of course adjustable along the platen with the

supports

14, 15, to accommodate cards or sheets of different widths; A card or sheet is introduced by' passing it down between the plate 39 and the platen, and pressing. it down between the fingers 3st and the platen. Then the platen is turned by a knob 40, and said fin- K eard 01 'shee afm wardly t0 1 11 i 10 I I I heiplaiten andi-rouifeed; the-'eard3f;orwa dl i writtenanpont, l 'lihe; card in; emerging from; the mat hme passes 31p {behind thddirec'trice'sf fllliw m may-b rm v lve d by. f i feed the c ardn'p from the printing line, and
