Definitions
- the particular object of my invention is to provide for such machines, a Work carrier universally movable for line and column spacing.
- Another object is to provide such a work carrier supporting the work at the printing point of a platen and adapted to yield under the impact 13 of recording or typing instrumentalities whereby the work is backed by the platen.
- Another object is to provide in combination with such a carrier means for effecting accurate line and column spacing movement thereof and 15 means for automatically returning the carrier to starting position.

- 1 desig- 53 nates a base, including a pair of spaced frame bars 2 connected together byfront and rear tie rods 3 and having, at their rear ends vertical brackets 4 and 5 respectively.
- the base 1 is designed to support the work ,35 carrier mechanism 6, in a horizontal plane beneath a recording mechanism preferably of the type illustrated conventionally at 7.
- This particular recording mechanism is disclosed in detail in my co-pending application, supra. It need merelybe stated herein that it is suitably susso pended between the brackets 4 and 5 and includes type carriers 8 provided with type 9 operative to print in a horizontal plane, a bar-like platen 10 mounted in suitable position Vbelow the type carriers 8 as shown at 11, and a ribbon mechanism 65 designated 12.
- the work carrier mechanism includes a series of three horizontally disposed rectangular frames 13, 14, and mounted in superposed relation to surround the platen 10 and position the top frame 7o 15 slightly above the top thereof.
- the lower frame 13 is stationary, being aixed to the frame bars 2, in right angular relation thereto and has its outside front and rear edges beveled to provide tracks 16 extending in the direction of letter 75 or column spacing.
- the second frame 14 ismounted upon the tracks 16 parallel to the frame 13 by grooved rollers 17 whereby it is movable thereon in column spacing direction.
- This frame 14 has its inside 80 side edges beveled to provide tracks 18 extending in a line spacing direction.
- the third or uppermost frame 15' is mounted upon the tracks 18 by grooved rollers 19 whereby it is movable on or relative to the frame 14 85 in a line space direction and with said frame in column spacing direction.
- a sheet of comparatively thin, light, preferably flexible material for instance rubberized fabric is stretched taut across the frame 15 and suitably fastened thereto, for 90 instance as illustrated in A Figure 9, to provide a diaphragm forming a sheet or work collating support or carrier 20 backed by or depressible against the platen 10.
- a gauge bar 21 (Fig. 4) is secured along one marginal edge of the frame 95 15 for aligning the marginal edges of work sheets collated on the carrier 20.
- a series of work clamping flngers 22 (Figs. 2 and 4) mounted upon a rock shaft 23 journaled on the gauge 10o bar 21 to descend in unison upon the edge -of the sheets under the action of suitably disposed springs 24.
- the rock shaft 23 is provided with a hand lever 25 for releasing said fingers and a spring urged latch 26 for holding the hand 105 lever 25 in released position.
- the work sheet carrier 20 is normally held in and automatically retracted to a first column first line position as follows.
- a suitably disposed resilient stop 27 on the frame 13 limits retractile movement of the 110 frame d14 and a suitable stop 28 on the frame 15 engages the frame 14 and retractile movement of the frame 15.
- a retracting drum 29 mounted at the rear of the base 1, is urged by a motor spring 30 to retract both frames 14 and 15 by means of a cable 31 having its ends connected to the drum 29 and frame 15 respectively andl passed around pulleys 32 on the frame 14.
- line locating mechanism comprising a line gauge plate 33 fixed to the frame 15 and cooperating with a line stop 34 fixed to the frame 14 to overlie the line gauge plate 33 ⁇ as shown in Fig. 5.
- the line gauge plate 33 is provided with two parallel rows of finger holes 35 spaced apart in each row at intervalscorresponding to double line spacing but staggered so that the holes in both rows'alternate at single line space intervals.
- the nger holes 35 maybe numbered alternately in sequence as indicated at 36. ⁇
- To effect line spacing the operator has merely to -place his finger in a selee-ted finger hole 35 and move the frame 15 and work carrier 20 until his ringer abuts and is arrested by the liri stop 34.
- a spring operated holding dog 37 pivoted upon the frame 14 engages a toothed rack 38 on the frame 15 and holds the latterfrom being returned.
- Column spacing is manually effected by moving the frame 14 together withthe frame 15 and work carrier 20 on the frame A13.
- column locating means including a series of nger holes 39 provided at column space intervals in the frame 13 into which the operator may insert his finger to act as a stop for the frame 14 as will be clear.
- the frame 14 carries a'suitably positioned resilientbumper40 for engaging the operators finger.
- a release lever 43 is pivoted at asuitable point upon the frame 14 and is operatively connectedl as by links 44 and 45 tothe holding dogs 37C and 41, respectively, to release them simultaneously whereupon the frames 14 and 15 and the work carrier 20 return to starting position yas will be apparent.
- the drum 29 constitutes a single motor operative to eiect relative movement of work and printing mechanism both laterally and longitudinally of the work to a predetermined writing position.
- a work carrier means supporting the carrier for movement in either line or column spacing directions, respectively, separate releasable mechanisms holding the carrier in selected line and column position, respectively, and'means for simultaneously releasing said mechanisms.
- a platen a work carrier, means supporting the carrier for movement over the platen in either line or column spacing directions, respectively, separate releasable mechanisms holding the carrier in selected line and column' positions, respectively, means for automatically returning the carrier to starting position upon release of the holding mechanisms, and means for simultaneously releasing said mechanisms.
- a work carrier In recording mechanism, a work carrier, means supporting'the carrier for movement in either vline or column spacing directions, respectively, and motor mechanism for returning the means supporting the work carrier for movement in line and column spacing directions, respectively, and a motor for moving said carrier in directions opposite to line and column spacing.
