Specification of Letters Patent.

Patented sepaaa, 1917.

Application filed March 21, 1918, Serial No. 756,016. Renewed February 28, 1917. Serial No. 151,568.

generally upon copy-holders of the general .-'description hereinafter set forth; also to construct the copy-holder so that it will have a wide range of adaptability, for instance, so that it will hold stenographers note books, ordinary books, loose sheets, etc.; also to improvethe line indicator, in which regard this invention is a special improvement upon the device shown in Patent No. 1032288 granted to me July 9, 1912; also to improve upon various 'detalls of construction and methods of operation, as will be more specifically pointed out hereinafter. And my 1nvention comprises the parts, im-

provements, and combinations hereinafter I and horizontal rods.

cal rod 15 is formed with a tenon 23, which pointed out and claimed.

In the drawings accompanying and form ing part of this specification and in the description of the drawings I have shown my invention in its preferred form and what I deem to be the best mode of-applying the, principles thereof; but it is to beunderstood that, within the scope of the appended claims, I. contemplate changes in form,"proportions, and materials, the transposition of parts, and the substitution of equivalent members, without departing from the spirit of my invention.

Figure 1 is a front elevation of a copyholder made in accordance with the princiles of my invention, certain concealed parts ing shown in dotted outlines. Fig. 2 is a sectional elevation approximately on the plane indicated by the line 2 in Fig. 1, with dotted outlines of certain concealed parts and of secondary positions of certain parts.

.Fig. 3 is a top view. Fig. 4 is an enlarged detail of the slide and other parts associated with the line indicator, being a sectional elevation approximately in the plane indicated by the line 4 in Fig. 5. Fig. 5 is another detail of the same parts, being a sectional elevation approximately on the.

line 5 in Fig. 4. Fig. 6 is an end view of the slide. Figs. 7, 8, and 9 are enlarged plan views showing certain details of the pivot joint of the adjusting arms.

Similar reference characters indicate like or corresponding parts throughout the sev- ;,eral views.

.The copy-support proper 10 is made of I sheet metal with a side flange 10 along each edge to strengthen it. To its back are secured two brackets or lugs 11, 11 between which is secured the upper end of the rod 12. The engagement is pivotal on the thumb-screw 13 ;''so that? the plate may be tilted thereon at any desired angle. The vertical rod 12 is pivoted at its lower end to the horizontal rod 14, which in turn is pivoted to the short vertical rod 15, Which is pivoted to the horizontal rod 16, and this is pivoted to the vertical rod or stem 17 which is slidable vertically in the hollow standard 20. The hollow standard is supported by the base 21, being secured thereto by the setscrew 22. The rod 17 is adjustable vertically in the hollow standard and is held in any desired position by the thumb-screw 19.

.In Figs. 2, 7, 8, and 9 I have shown the "1 imeans employed 'for pivotin the vertical The en of the vertiis flattened on one side, as shown at 24. The end of each of the horizontal rods 14 and 16 is rabbeted on both sides, as shown at 25, and has a h01e26 fitting over thetenon so as to be rotatable thereon. 27 is a washer having a hole-corresponding in shape and size with the cross section of the tenon, as

shown at 28 29 is a screw engaging in the tenon as shown. The washer, the tenon, and

-.the end of the horizontal rod are so related that the screw head does not touch the end 'of the tenon even when screwed down tight. This arrangement permits the pivot to be tightened to any degree without the Working of the pivot further tightening or loossuing the joint.

The plate 10 is provided at its-upper edge with a rearwardly extending flange 30 having a number, preferably three, of strips 31, 31, 31 rolled over to form the bearing fora rod 32 which extends beyond the sides of the plate. To this rod or shaft is rigidly secured the two semi-circular arms 33,. 33 of the presser rod 34 which extends across the upper part of'the plate and thus has pivotal support in said bearing for the shaft 31. I provide two coil springs 35, 35 whose tension upon the shaft forces the presser rod against'the plate, in order to hold the copy firmly on plate. But the presser rod can be easily raised by hand, as

. indicated at 33 against the tension of the springs,- to insert or withdraw the copy.

A rod that is square in cross section is so bent as to form two parallel arms 36, 38, preferably of unequal length, with a rightangular connection portion 37. Across-the plate I press out a number of clips 39 which are in proper alinement and of proper form to form a lgiplder and way for one of said parallel. the other arm being back of the plate. The purpose of this device is to hold the loose pages of the note book as they are turrgd back. The device may be adjusted lengthwise of the arms; either arm may be turned to the rear; so as to make it the most efficient and convenient for the copy held.

Another rod, this being a round rod, is formed with two parallel arms 40, 41, which are slidably fitted in the clips 47, 47 which are turned back from the sheet plate to form holders for said rods. The left-hand ends of these rods are continued rearwardly, as

shown at 42 and 43, respectively; thence the upper one .continues upwardly, as shown at 44, and the lower one downwardly, as shown at 45. Thence each makes an outward loop connected by the vertical rod 46, which is thus parallel with the side edges of the plate but back of the plane of the plate. 48 is a bracket with two legs 49, 50, each leg having a hole 51 to engage the rod 46. A slot 52 extends from the hole and receives'the pins or tenons 53 formed in the opposite ends of the round key 54 which fits in the roove 55 which extends longitudinally of the rod 46. A spring 56 bears against said key and tends to force it against the rod 46 and into the groove. The spring is notched at each end, as shown at 57, where it engages the key, to hold it in place. The slots 52 are of sufficientlength to permit the movement of the key necessary to let the key into the groove and to let it bear against the other portions of the rod 46. One of said legs is formed with a socket 60 in which is slidably held a square rod 61 extending at right angles to the plane of the plate, and having a portion 62 bent over parallel with the plate and extending transversely across the same. The parts are so arranged that the key is in the groove when the rod 62 is parallel with the plane of the plate. The spring holds these parts quite firmly in this position; yet the same may be oscillated by hand so as to shift the rod 62 clear of the plate. The rod 62 constitutes the line in dicator. It may be shifted up and down by moving the clamp up and down on the rod 46. It may be set nearer to or farther away from the plate by moving the rod 61 in its socket. And the entire line indicator mech anism may be shifted farther to the left, as when it is to be used for a wider copy, by 65 shifting it so the rods 40, 41 move lengthwise in their bearings 47, 47. And it may be removed entirely from the plate.

62 is a shelfhinged to the lower edge 63 of the plate, as upon a rod 64. 65 is a plate secured to the under side of the'shelf and provided with a rearwardly extending arm 66 pivoted at its rear end to the lower end of a latch 67 whose upper and free end works in a casing 68 secured to the back of the plate. 69 is a spring bearing against said free end and forcing the latch against the plate, especially so said-latch will engage under the lug 70 which is pressed back from the plate. These parts hold the shelf at substantially a right angle to the plate; in which position the shelf is of special usefulness in supporting a book. 71 is an extension of the latch -below its pivot, and forms a finger piece for releasing the latch from the lug 70; the operation being to pull the finger plece forward, as indicated by the dotted outline 71 until the latch is clear of the lug 70 and then loweringthe shelf so that it is brought in the same plane with the plate, as indicated at 62 in dotted outlines. In this position the latch merely telescopes within the casing and is out of the way, the shelf forming merely a continuation of the plate, or a longer plate. The shelf may be brought into use as a shelf roper by merely turnin it up again until the latch catches under t e lug. This construction is simple, strong, durable, and efficient, and it is easily operated in adjusting. The purpose of the peculiar shape of the supporting rod for the line indicator attachment, namely, the upwardly and the downwardly extending loops, is to permit the line indicator to be moved upwardly and downwardly farther than would be possible without these extensions. It will be noted that with this arrangement, it is possible to move the line indicator clear up to the top of the plate, and it is also possible to move it clear down to the shelf; and, if it were desired, the lower loop could be farther extended so as to permit the line indicator to 'be moved clear down to the bottom of the shelf when in downward position.

What I claim is:

1. In a copy-holder, the combination of a plate, a shelf hinged to the lower edge thereof and capable of two positions in one of which it extends forwardly substantially at a right angle to the plate and in the other of which it is substantially in the same plane with the plate, an arm extendin rearwardly from the under side of the s elf, an upwardly extending pawl pivoted to said. arm and located back of the plate, said plate being formed with a lughagainst which said pawl engages to hold t e shelf in its rightangular position, a casing secured to the back of the plate and inclosing the upper end of the pawl, and a spring secured to the 130 the under side thereof, a latch pivoted at its lower end to the rear end of said arm, said plate being formed with a rearwardly extending lug against which said pawl has locking engagement, and a spring forcing the pawl into engagement with the lug, said pawl being adapted to engage the. lug and hold the shelf in a holding position substan tially at right angles to the plane of the plate, and adapted when released from the lug to permit the shelf to oscillate downwardly on its hinge.

In testimony whereof I have afiixed my signature in presence of two witnesses.
