COPY-HOLDER.

Specificationof Letters. Patent.

Patented Dec. 31, 1918.

Application filed January 24, 1916. Serial No. 73,924.

To all whom it may concern:

Be it known that 1, CHARLES ENGLERT, a citizen of the United States; and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Copy- Holders, of which the following is a specification.

The present invention relates to copy holders and more particularly to the typein which a line guide and a work holder are relatively movable for the purpose of pointing out on the Work successive lines to be copied, an object of this invention being to provide a construction evhich will permit the return movement of the movable part relatively to the stationary part by mere pressure on such movable part, so that the manipulation of the shifting or operating devices .to effect the release of the movable part, and the pro visionof devices. for cushioning the descent of the movable part will be eliminated. Another object of the invention is to provide a construction which is simple in operation, inexpensive to manufacture and not liable to get out of order. A further object of the invention is to provide means of simple construction for retaining the movable part in the position to which it is adjusted, and at the same time permit the said removable part to be lowered readily without any j arring action. A still. further object of the invention is to provide a line guide behind which the work may be quickly fitted, and.

which is quickly adjustable to conform to work of different widths.

To these and other ends,the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:-

Figure 1 is a front view .of a'copy holder embodying the present improvements;

Fig. 2 is a vertical section through the copy holder;

Fig. 3 is an enlarged plan view of the copy holder with oneend broken; away; and

Fig. .4; is an enlarged rear. view' of the upper end of the .copy'holder with an end portion broken away.

According to this invention there is provided a supporting-frame embodying preferably a weightedbase 1 and a tubular standard 2 rising therefrom and having its lower-end fitted in-a socket 2-'in the'base.

The upper end of this frame 2 may be closed by a cap3 provided with an eccentric opening, while, within the standard, a partition A is arranged also provided with an eccentric opening which is vertically below the eccentric opening in the cap 3, the walls of these two openings serving as guiding means for the work supporting-member.

The work supporting-member preferably embodies a non-circular stem 5 of rectangular cross section operating through the cap 3 and the partition 4, and carrying, at its upper end," a cross-piece 6. This cross-piece is preferably formed from sheet metal, bent substantially into U-shape in cross-section to provide a pair of parallel horizontal flanges 7 which at their centers are provided with perforated lugs 8. Through these lugs a reduced portion. 9 on the stem at passes, the

lugs being held apart by a spacing tube 10 which surrounds the reduced portion 9. A nut 11 on the end of the reduced portion secures thecross-piece 6 to the stem 5.

With the end in view of raising the wvork support on its supporting-frame, there may be provided a rod 12 guided at 13 011 the walls of an opening. in the partition 4 and carrying at its upper end a clutch-member 14 which is mounted to swing on said end and is provided with an opening 15 through which the stem 5 passes. When the stem 12 is raised, it lifts the clutch-member 14: which,

in turn, by its engagement .with the stem 5,

raises the work-holder, after which the clutch-member 14 returns. to the. Position shown in Fig. 2. Any suitable means may be employed for raisingthe rod 12, but preferably a lever 16 is pivoted at 17 to the base 1 and provided at its forward end with a finger piece 18 and, at its rearward end, it extends through a slot in the lower end of the tubing 2, connecting pivotally at 19 with the lower end of the rod 12. A spring 20 is arranged between said lever 16 and the base 1 to maintain the lever 16 in an elevated positionat its fonward end, while an adjustable stop 22 passes through an arm 23 on the lever 16 in order. that its lower end may cooperate with the base 1 to adjustably limit the depression. movement of the operating lever 16 and thereby control the feeding movement of the work supporting-member.

For retaining the work supporting-member: in its adjusted position, two: friction grips .24? are provided for cooperating with opposite faces of the stem 5. These friction weights yet, at the same time, permitting the descent ofthe work holder when pressure is applied to the latter in a downward direction. The work is held on the work holder by a work holding means comprising preferably two spring arms extending inwardly from opposite ends of the cross-piece 6 and adjustable toward and from each other. This adjustment may be obtained by providing the spring arms with guide arms 27' forming with the spring arms substantially U-shaped members. These guide arms are mounted to slide on the cross-head 6 and the latter for this purpose has flanges 28 bent from the upper and lower edges thereof at opposite ends to provide sleeves 29 in which the guide arms 27 operate.

For the purpose of holding the turned leaves of stenographers note books or tablets, the cross-arm or head 6 may also carry two spring arms or clasps 30 extending inwardly from opposite ends of the cross-head, and these arms may also be adjusted toward and from each other, the adjustment being effected by guide arms 31 in one piece with the spring arms to form U-shaped members, the guide arms also being slidable in the sleeves '29 in the direction of the length of the cross-head 6.

It is also desirable to provide in copy holders of this character, a stationary line guide past which the work is carried by the Y .work holder.

This line guide, in this instance, comprises a central backing sectlon formed from sheet metal and bent into U-form to provide upper and lower flanges 33, the upper flange having a central lug 34 provided with a slot 35 and secured to the upper face ofv the cap 3 by screws 36 which also servefor securing the spring plate 24. The backing member also comprises two end sections 37 adjustable on the central section 32 in sleeves formed by bending tongues 38 inwardly from the flanges 33 of the central member. Pivotally connected at 39 to each of the end sections 37 are links 40 whi'h, in turn, are pivoted at 41 to a line guide member. Preferably, this line guide memher is flexible and extensible so that it may be made to accommodate workof different widths. As illustrated it is formed of two sections 42 of thin flexible sheet metal, each having a loop 43 at its end surrounding the a other section an i each being conne"ted with a link 40 by a pivot 41. A plate .44 with its upper edge 45 deflected rearwardly is se cured by tongues 46 to the backing member 32 and thus .increases the width of the backing member at the central portion thereof so that the work will have a wide bearing at this point.

The work holder may carry a' clamping means forsecuring it to a desk or typewriter support, and this clamping means is preferably removable and is also adapted to be attached to a number of sides of the base so that any edge of a top of a typewriter support may be clamped. In this instance, the base 1 is provided with a socket 47 at its front and with a transverse socket 48 opening at opposite sides of the support. Any one of these sockets is adapted to receivean arm 49 of a U-shaped clamp. while the other arm 50 ofsaid clamp carries an adjusting screw 51 having a hand piece 52 and a clamping. portion 53, the clamping portion being opposed to the bottom of the base in order to hold the latter firmly to a suitable support.

The invention will be understood from the foregoing description, but it may be summarized as follows:

The work is secured to the cross head 6 by the oppositely extending clamping arms 25 which are adjusted on the cross head to correspond to the width of the .work. The depending portion of the work is introduced between the guide member and the backing member of the line guide by flexing the guide member laterally, the guide member also being adjusted to correspond to the width of the work. The work is raised by depressing the lever 16 periodically and this causes the clutch member 14 to operate upon the stem 5 of the work support. The grips 24 hold the work support in this adjusted position but permit the depression thereof. After one sheet of the work has beenbopied. it is thrown over thecross head 6 and held bv the arms 30, which are also adjusted to correspond to the width of the work.

A work holder constructed in accordance with this invention is inexpensive to manufacture and simple in operation, the operating parts are housed so as to protect it against dust and malicious operation. The size of the supporting frame has been reduced to a minimum and it is thereby adapted to be arranged in a space of small compass. The work holding means which secures the work on the work support is of simple 7 construction and may be easily manipulated. The line guide is of novel form and readily permits the insertion of the work therein while effectively pointing out the line.
