a BY YTEJ E J0 Patented June 9, 1942 UNITED STATES PATENT OFFICE 1 Claim.

This invention aims to provide a novel means whereby a copy holder may be maintained in a variety of positions on a lintotype machine or any other similar instrumentality, with a View to presenting the copy in proper position with respect to the operator.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the cope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows in front elevation, a device constructed in accordance with the invention;

Fig. 2 is an end elevation;

Fig. 3 is a rear elevation;

Fig. 4 is a perspective view showing the lazy tongs and attendant parts;

Fig. 5 is a cross section on the line 5-5 of Fig. 2;

Fig. 6 is a detailed sectional view showing a minor modification.

In carrying out the invention, there is provided a track I, which, preferably, is in the form of a bar of circular cross section. By means of screws 2, the track I is secured to the linotype or other machine, and the track I is provided with rectangular recesses 3, adapted to receive correspondingly shaped shims 4, which raise the track I sufliciently to allow proper clearance between the device forming the subject matter of this application and the machine whereon it is mounted. Owing to the way in which the recesses 3 and the shims 4 are formed, the track I will not rotate about a horizontal axis. At one end, the track I has a hole 5, for the reception of one of the securing elements 2, the track being provided at its opposite end with a slot 6, for the reception of the other of the securing elements.

A carriage I i provided, and may be an angle member, including a first flange 8 and a second flange 9 disposed at right angles thereto. The second flange Q'is provided at its ends with rectangularly disposed ears II], having openings II for the reception of the track I. The construction is such that the carriage 'I may be shifted lengthwise of the track I, or be adjusted circumferentially thereof. In order to hold the carriage I in any position to which it may have been adjusted, either longitudinally of the track I or circumferentially thereof, the second flange 9 is provided with releasable holding devices, adapted to engage the track. The holding devices may be set screws I2, threaded into the flange 9.

A lazy tongs mechanism I4 is provided, and includes first or rear links I5, having their rear ends connected by headed pivot elements I6 to the flange 8 of the carriage I. The lazy tongs mechanism I4 includes second or forward links H, connected to the links I5 by headed pivot elements I8. By means of headed pivot elements I9, the links H are connected to a support 20, in the form of a rod, disposed considerably ahead of the track I.

The numeral 2| marks a copy holder, whereon a combined line finder and paper retainer 22 is mounted at 23. The copy holder and the line finder may be constructed as desired.

Headed studs 24 project rearwardly from the copy holder 2|, and carry fixed jaws 25, abutting against the rear surface of the copy holder. Cooperating movable jaws 26 are mounted on the studs 24, the jaws 26 and. 25 being recessed as shown at 21, to fit closely on the track I. In the interest of creating increased holding friction, compression springs 28 are mounted on the studs 24, on the pivot elements I9, on the pivot elements I8, and on the pivot elements I6. In View of the showing of the drawings, it is unnecessary to specify the various parts which are held intimately and frictionally together by the springs 28.

As shown in Fig. 6, the springs 28 may be omitted, rivets 50 being relied upon to afford the necessary friction between parts such as I5a and I'Ia. The following adjustments, governing the position of the copy holder 2| with respect to the operator, are possible: a movement of the copy holder lengthwise of the support 20, as shown by the arrows A in Fig. 3: a front to back swinging movement of the copy holder on the support 20, as shown by the arrows B in Fig. 2: a front to back adjustment of the copy holder, indicated by the arrows C in Fig. 3: a movement of either end of the copy holder, toward and from the track I, as indicated by the arrows D in Fig. 3: a shifting of the carriage I and the copy holder 2|, lengthwise of the track I, as indicated by the arrows E in Fig. 3: and a movement of the carriage 1 and the parts which it supports, circumferentially of the track I, as indicated by the arrows F in Fig. 2.

From the foregoing, it will be observed that the device is capable of meeting any reasonable demand that may be made upon it, so far as the position of the copy holder 2| with respect to the operator is concerned.

Owing to the many adjustments of which the copy holder 2| is capable, eye strain will be avoided, and glare, shadows and cross-lights will be avoided.

Having thus described the invention, what is claimed is:

In a copy rack, a copy holder, a rod-like, approximately-horizontal support, spaced connectors joining the holder with the support for governed rocking movement transversely ofthe axis of the support, a single pair of forward links, a single pair of rear links, pivot means connecting the forward end of each rear link with the rear end of one forward link, for movement in a plane parallel to the support, and to permit the pivotally connected links to fold laterally in opposite directions, means for pivotally joining the forward ends of the forward links to the support at spaced points located between the connectors, for movement in a plane parallel to the support, a carriage, means for pivotally connecting the rear ends of the rear links to the carriage at spaced points, for movement in a plane parallel to the support, a track whereon the carriage is mounted to slide laterally and to swing vertically, the track being of such length that the carriage may have a wide range of lateral adjustment thereon, means for holding the carriage releasably fixed with respect to the track, and means for mounting the track terminally on a linotype machine, in a practically horizontal position.
