Opinion

Jackson, Judge,

delivered the opinion of the court:

This is an appeal from a decision of the Board of Appeals of the United States Patent Office, affirming a decision of the Primary Examiner, finally rejecting all of the claims, 4, 5, 8,10 to 12, inclusive, 14, and 15, of an application, serial No. 506,492, filed October 16, 1948, for a patent alleging new and useful improvements in “CONTROL AND MEASUREMENT OF LINEAR SPACING IN TYPEWRITING MACHINES,” on the ground that they fail to define invention over the following prior art:

Crane et al., 2,151,191, March 21,1939.
Ritterholz, 2,162,565, June 13, 1939.
Roberts, 2,192,330, March 5, 1940.
Hausman, 2,205,289, June 18,1940.

Claims 4 and 10 are illustrative of the involved subject matter and read as follows:

4. In a typewriting machine a control means, operable independently of the escapement and printing mechanism, causing lateral movement of the carriage to any desired extent in either direction, in combination with a scale means measuring visibly to the operator, when in position to operate, the extent of such movement.
10. In a typewriting machine, in combination, a platen carriage mounted for longitudinal movement transversely of said machine, a rack carried with said carriage, an escapement pinion meshing with said rack, secondary teeth on said rack, a control gear meshing with said secondary teeth, a shaft carrying said [1040]*1040gear mounted on the end of said carriage, means for rotating said shaft, a control member for such rotating means within reach of the operator, and a scale, visible to the operator, in position to operate, with relation to which said control means moves, all of said parts being carried at one end of said platen carriage.

Claims 4, 5, and 12 were rejected as unpatentable over tire Hausman reference. Claims 4 and 5 were also rejected upon the patent to Crane et a 1., and all of the claims were further rejected on the patent to Eoberts.

The alleged invention has to do with the control and measurement of linear spacing in typewriting machines. It is said that one of the objects of the claimed invention is the provision of mechanism by means of which the typist in operating the machine may change to the extent desired in either direction the relation between the printing point and the impression receiving surface and measure the extent of such change. Such means or mechanism is operated independently of the escapement means, the printing-mechanism, and the key operations, and the operator by said control means is enabled to measure the linear space between any two points on the printing surface and set any desired number of letters or characters evenly into such space. The claimed structure may be applied to any kind of typewriting machine and used not only for the alteration of spacing between letters, but also for printing justification. Justification apparently means spacing between words and letters on a line in such a way as to obtain an even right hand margin. The drawings in the application disclose a conventional typewriter in which the carriage rack is coimected to the platen carriage frame by studs passing through slots in the carriage rack. The cooperation between the studs and the slots permits movement in either direction to the length of the slots. In operation, to control the relative position of the platen carriage and the printing point independently of the escapement mechanism and key controls, the operator turns what is known as the operating lever in order to release a brake and mov.es the lever along a quadrant scale, the movements on which are shown to be magnified, and within the line of vision of the operator. When the lever is moved, operating gear, which is in mesh with the teeth at the end of the escapement, is turned at the lower end of a cooperating shaft and the gear moves along with said teeth while the platen carriage frame associated therewith will move to the extent above indicated.

The patent to Crane et al. is for improvements in typewriting machines for “regulating and varying the spacing between the charac«ters printed by the machine.” It is shown in the drawings that instead of the rack member of the conventional machine, a long annular spring has been substituted which cooperates with the escapement mechanism. [1041]*1041The spring is fixed to the carriage at one end by being passed through a hole in the carriage supported mandrel around which the spring is wound and to the end of a jack screw, motivated by a crank handle mounted in a bracket on the other end of the mandrel. When the crank is turned, the jack screw tensions the spring or allows it to contract and thus the desired spacing is obtained. A calibrated measuring scale is mounted over the jack screw element and cooperates with the spacing made by the turning of the j ack screw.

The patent to Ritterholz is concerned with typewriting machines in conection with justification method and means in the operation of the machine. One of the objects is stated to be “the correction of words to a modified space in the line,” and it is said that the device, which may be built into any standard typewriting machine, provides a readily usable guide designed to assist even the most inexperienced operator and also for ready production of line justification. The patentee in his structure discloses mechanism which moves jointly with the carriage and by imparting a rotary movement to a shaft situated on the right hand side of the machine, the platen and paper holding cylinders are moved longitudinally relative to the carriage, thus modifying the normal space used in a typewriter by the addition or subtraction of an amount proportionate to the distance in which the platen is shifted with respect to the carriage. The shaft, which is designed to have rotary movement, has on its front side, and in clear view, a circular handle for manually turning the shaft in either direction. The handle is of a dial type and contains calibrations for the representation of longitudinal adjustment of the platen supporting shaft and its associated parts.

The Roberts reference relates to line justifying mechanism for typewriters and the like, and it is said that the claimed mechanism of the patent may be adapted to standard typewriters and other key operated machines. The drawings disclose an escapement rack which is so mounted that it is adjustable with relation to the carriagé, by means of slots in the rack cooperating with guide pins on the carriage. The adjusting mechanism is supported on a bracket on one end of the carriage. The bracket is provided with a pair of forks between which there is a spindle slidably mounted. The spindle is prevented from rotating by means ofo a pin. On the spindle is a grooved collar which is engaged by another fork at the end of the escapement rack in such fashion that when the spindle is moved to the right, the escapement rack moves with it. The spindle may be slidably moved by- means comprising a thread on the spindle cooperating with a thread in the bore of a beveled pinion and a further beveled pinion on a shaft which is turnable by means of a division setter comprising a knob and a disc part. Under the knob is the conical disc upon which is a scale for the [1042]*1042purpose of indicating the distance of movement.
