BARNARD RECORDING MACHINE Filed April 27, 1942 2 Sheets-Sheet 2 sPatented Mar. 14, 1944' UNIT ED STATES PATENT OFFICE RECORDING MACHINE Henry HJBarnard, Washington, I). 0. Application April 27, 1942 :Serial No. 440.721 '7 Claims. (01. 33-36) The present invention relates to recording mechanism for applying on a record sheet :any .desired data, particularly by means of a series of lines.

It is anobj'ect of the invention 'to 'provide ne or morerecording units mounted on an 'adjustable frame. .-A further object resides in providing indicating means and line drawing or printing elements for each unit, preferably a pair of indicating and printing elements for-each unit. .A still further object of the invention resides in the provision of means for shifting all the units simultaneously 'a certain distance in a direction :at right angles to the printing direction of the recorded lines.

Another object of thetinvention .is -to provide means for inking-a printing rolier'for each printing element as the latter 'is adjusted to the position where th reqm'red :lines are to be drawn. The printing rollers are-each provided with means toprinta so-called'wavy or scalloped line to render it readily distinguishable from other lines to be manually recorded on a record sheet.

Further objects-will be apparent from'the following description taken in connection with the accompanying drawings in which, 7

The entire machine may comprise a panel or board 8 acting as a base frame or support. The

board 8 has a dove-tail projecting rail 9, Fig. 2, along one side of the board which as seen in Fig. 1 may be termed the upper part or edge Ill. This rail 9 receives a strip portion or slidable bar Ii having a groove l2 in the underside thereof which has a configuration similar to the dovetail projecting rail 9, thus providing for a snug fit and a relative slidable movement. A rectangular fram I3 is hinged to the bar I! by means of suitably spaced hinges l4. Along the bottom part IS a short gear rack H5 is secured on the panel 8 which is adapted to cooperate with three pins l1, Figs. 1 and 5, rotatably mounted on a spindle l8 and having a knurled knob l9 to rotate the spindle and pins. The spindle l8 "underside thereof in the of recording and indicating devices 255 and '21 is mounted 'in a bearing-bracket :29 :secured on the frame l3. When it is desired to shift the frame 13 to the right-or left, Fig. 1, it :is merely necessary to .manuallyrota'te theknob IS whereby one of the :end pins H of the three, depending upon the direction of rotation, will pivot-between two teeth of the rack i6, 'Fig. 5,'to thereby shift and slide the frame 13 withfits units iniitsentirety upon the dove-tail rail '9.

A plurality of indicating and-recording units 2! are suitably secured on the frame I Son-theunber and lower members 22 and 23 by means of screws or thelike, Fig.2. Each unit 2-l consistsofa base bar 24 having a plurality of teeth 25 .on the form 10f .a :rack. ,A pair are mounted to slide :on the bar 24 and each recording device is provided with :a fiat spring .28 which is adapted, by :coiling action, to pull the device back to its end position, Fig. 2, when the devices are not in use.

Anendcasing 29 houses thecoiled spring and from which it :uncoils from around the center pin -30 when the respectivedevice 2i isinuse. EEach casing 25 is suitably secured, 'by means :of screws 3-! for instance to the respectiveendofjthe bar .24.

. :Each recording and indicating-device '26 and .21 is composed of a main U-shaped frame 32 which fits in an inverted position over r-the, bar 2.4, Fig. 3. An auxiliary frame 33 of double U- shape fits on the main frame .3 2 by means-of the actuating U-shaped branch .34 having a gear wheel 35 rotatably mountedtherein. This .gear wheel 35 is adapted to mesh with the rack 25. The other U-shapedbranch 35 carries a printing roller 31 and an inking'roller 38. Aleg 33 is commonto both U-shaped branches 3 and 36. A shaft 4% on which the gear wheel 35 is mounted also carries the printing roller 31 and both'the gear wheel and printing roller3-1 are securely mounted torotate with the shaft "49 ""for'the'purpose which will be explained. An operating handle 4! is secured on the auxiliary frame 33 and a spring 42 between said frame and the main frame 32 forces the auxiliary frame and its rollers in the non-printing position.

The auxiliary frame 33 is provided with a pointer 43 which is slightly bent at an angle to point on or toward a record sheet 44.

If desired the top of the bar 24 may be with a strip 45 carrying a. scale or other data or numbers.

It is also obvious that the printing roller may be provided to record one or more lines 56 as may be desired, as shown in Fig. 6, in which for provided desired In the positions of the parts of the units as shown in Figs. 1 and 2 are non-recording and the devices 26 and 21 are in their inoperative and non-indicating positions, each pair 25 and 21 of a unit 2| being pulled and held to each end an opening therein,

to draw a line through the opening in the frame on a record sheet on the base support.

2. A recording machine according to claim 1, in which means are provided on the support and the frame cooperat' g with the rail to shift the bar and frame a predetermined distance on the support.

3. A recording machine comprising a base support, a bar slidably mounted on the base support, a frame hingedly secured on the bar and having a line marking unit mounted and secured on the frame said unit having at of the bar 24 by means of its respective spring 28. If it is desired to record one or more lines 41 or 48, it is merely necessary to move the device 26 or 21 a short distance by the handle 4| Without forcing the frame 33 down so that the gear 35 by means of the rack 25 will rotate the printing roller 3! to apply ink thereto and then where desired to start the printing, the frame 33 by meansof the handle 4| is pressed down whereby the printing roller 31 will print a line or lines 4! or 48 on the record sheet 44. It will be observed that the rollers 31 while printing will be constantly inked, due to rolling contact with its inking roller 38.

As seen in Figs. 1 and 2, one way in which the machine may be used is for maintaining knowledge of and posting production of certain items, machines, units and assemblies, in which each block of rectangles represents monthly items, and in which the lines 48, Fig. '7, may indicate the quota to be reached each month, and lines 4'! the actual number of items produced or completed. If, for instance, in some months the production may exceed the quota set therefor the lines which overlap will form a chain configuration where a form of lines 46 is chosen in which the small loops extend in opposite directions in the respective rollers 31 as seen in Fig. 6. It is obvious that each roller 31 may print one or any number of lines, and such lines may be straight or'may comprise any desired configuration.

The shifting device I 6 to 28 may be so conv structed to laterally move the frame l3 and the units 2| any desired distance, such as one space represented by one longitudinal recording subdivision, as shown o the record sheet 44.

I claim as my invention:

1. A recording machine comprising a base support having a dove-tail projecting rail thereon, a bar having a dove-tail groove therein mounted on the support and slidable on the dove-tail projecting rail, a frame hingedly secured on the least one indicating and recording device thereon and adapted to draw lines through an opening in the frame on a record sheet on said base support, and means for shifting the frame and unit on the base support including a gear rack and an actuating member.

4. In a recording machine having a frame movably mounted on a record sheet support, a recording unit mounted on the frame and comprising a base bar, an indicating and recording device slidably mounted on said base bar, a printing roller rotatably mounted in said device, an inking roller rotatably mounted in the device above and in contact with the printing roller, and means on the device and on the base bar to rotate the printing roller to provide ink thereon from the inking roller.

5. A recording unit according to claim 4, in which means are provided to pull the unit back to a non-recording position adjacent the frame after use.

7. A recording unit for a recording machine comprising a base bar, a main U-shaped frame mounted to partially surround and to slide on the base bar, a U-shaped auxiliary frame mounted on and to partially surround the main frame and movable relative thereto, a printing device mounted in the auxiliary frame, and means on the base bar and mounted in the auxiliary frame to rotate the printing device upon sliding move ment of the main frame.
