JOHN E. BUCKLIN, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO THE BUCKLIN COPY HOLDER COMPANY, OF RICHMOND, VIRGINIA.

COPY-HOLDER.

SPECIFIGATION forming part of Letters Patent No. 526,990, dated October 2, 1894.

Application filed May 29,1894. serial No. 512.349- (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. BUCKLIN, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Copy-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apro pertains to make and use the same.

My invention relates to certain new and usefulimprovementsin copy holders for typewriters and particularly to that class in which the copy moving cylinder is operated by a pivoted swinging key or lever.

My invention has for its object to provide a copy holder which shall be economic of construction, adjustable in its parts and compact in form, so thatany given extent of the copy may be exposed to view and the copy moved in such manner that the lines of the copy will progress to the same extent as the matter is printed upon the sheet in. the typewriter, thus enabling the operator to success- 2 5 fully make lineal copies.

With these ends in view myinvention consists in the details of construction and the combination and arrangement of parts hereinafter fully described and specifically claimed.

In order that those skilled in the art to which my invention pertains may know how to make and use my improved copy holder I will proceed to describe the construction and operation of the same referring by letters to V 5' the accompanying drawings, in which- Figure 1 is aperspective view of a copy holder embodying my invention. Fig. 2 is a side elevation partly in section. Fig. 3 is a side elevation showing the holder folded up in its most compact form for transportation. Fig. 4 is a side view on an enlarged or full sized scale and broken away above and below the moving cylinder. Fig. 5 is a full size Similar letters indicate like parts in the several figures of the drawings.

A is aframe composed preferably of metal and fashioned at its lower end in any suitable manner to provide supporting legs or feet B, B. Pivoted to the frame A below the moving cylinder is an auxiliary frame C terminating at its free end in feet or supports D, and the outward movement of said auxiliary frame is limited by the contact of the upper extension of said frame with the stops a on the main frame A. (See Figs. 1 and 6.)

On the main frame A at the left hand side is secured by screws 19 a journal bearing E into which one end of the journal of the cylinder F takes its bearing. To the opposite side of the frame A is secured in a similar manner a plate G (see Fig. 4: particularly) which serves asthe journal bearing for the opposite end of cylinder F. This plate G is formed with a curved or oblique arm H and is extended rearward and provided with a stud or stop I. (Shown in dotted lines.)

The journal of the cylinder F takes its bearing in the plate G- and extends through the same and is provided at its extreme end with a milled thumb wheel J, by means of which the cylinder may be readily rotated in either direction.

The journal also passes through a plate K (see Fig. 5) and between this plate and the milled wheel J there is secured to the shaft orjournal of the cylinder F, preferably by a set screw 0 (see Fig. 4) a friction wheel L.

The plate K is free to vibrate upon the 8 5 shaft of the cylinder F,and its upward movement is controlled by mechanism presently described, and its return movement by the stop I and retracting spring M, one end of which is secured to a stud on said plate and 0 the opposite end to a stud d on the main frame A.

To the plate K is pivoted at N a friction dog 0, the downward movement of which is limited bya screw or stud P secured to the swinging plate K.

Q is an irregularly curved arm orlever pivoted at a point between its ends to the arm H of the plate or bearing G. The rear end is pivoted to a link bar R, the upper end of I00 whichispivoted to the heel or rear end of the dog 0. The forward end of the arm Qis pivotally connected with a flat rod or link S,

the lower end of which is, by a series of holes 6 and a screwf, adapted to be adjustably Ipivotedto the endof .a swinging operating, l

frameT pivoted at each end tot-he "main;

frame A, and provided ;at any suitable locality with a key U. I

The irregularly curved vibrating arm Q- back of and below the point at which it is pivoted to the arm H is connected by aspring.

Vto the main frame preferably with thepivot by which the swinging frameT 'is also connected.

W is an adjustable plate provided with a longitudinal slot and a "set screw .X, and formed at its lower end withatstop Y which: limits the upward m'ovementofthe swinging plate K to which the friction dog t) is pivoted, andhence the extent ofthe rotation of,

the cylinderF is controlled.

The upperendsofvthe mainframe A are connected by ahorizontal rod around which is secured the upper edge of a sheet metal swinging copy snpportZ the -low er edge of which lies just'below the upper-peripheriesof the rollers F, and B as shown inrFig. 1, and,

serves to also guide the sheet intothebite ofl To this horizontal bar isalso the said rollers. pivoted a vertical swinging frame A between the lower ends of which is secured in suitable bearings a clamping roller or cylinder B, and

the lower ends of the frame Aare connected with the main frame A byspiral springs G to produce the properbite between the rollers or cylinders F and B between which the copy is held.

Df, D are two swingingarms ,pivoted at their upper ends to theextremeends of the main frame A and frictionally secured to these arms D',D' is a fiatplate E'which may be made compact for transportation, the

screw or pivot which secures the "lower end of the arm S to the frame T is removed. The frame T is then folded upas shown at Fig. 3

by rempving the pivots which connect the lower end of the arm Q and the link B. When the parts areintheir normaland proper.re-

ilation to each other the :friction dog 0 is slightly away from or out of contact with the friction wheel or pulley J, and when pressure is applied to the key U and the frame T 18 depressed, the rod or link S pulling upon the .arm Qcauses it to vibrate upon its pivot in the arm I-I forcing up thelinkR and bringing thebiting edge ofthe dog 0 in contact with the periphery of the friction wheel .T, and

then the plateK and dog 0 vibrate upon the shaft of the cylinder, rotating the same and the roller or-cylinderF a distanceproportionate to the movement of the frame Tuwhich as before statedwill be limited by the fact that theupperledge of the plate K comes in contact with the adjustablestop Y, and the copy which is in the bite of the rolls Band B is forced upward accordingly. When the pressure is removed from the key U and frame T the spring V pulls down the :rear end of the arm Q and with it thedog 0 until thelatter comes in contact with the stop P on the swingingplate K, and the latter is at the same time drawn downwardly by the springV until the rear end of said plate comes in contact with the stop 111, thus releasing contact between the dog and friction Wheel.

Having described the construction and operation of my improvedcopy-holder,What I claim as new, and desire to secure by Letters Patent, is-

,1. In combination with the frame A and platesE, G, having the cylinder F mounted therein said cylinder being provided with friction wheel J the swinging plate K',;pawl or dog 0 pivoted thereto, link R,armsQ and H, rod S, swinging frame T, retracting springs M, V, andstops I, P, substantially as and for the purpose set forth.

2. The combination and arrangement of the frame A,.roll or cylinder F, journaled therein, therollB, journaled in the swingingtframe A", plate Z, swinging arms D',D and adjustable plate E, substantially as and for the purpose setforth.

In testimony whereofl affixmy signature in presence of two witnesses.

JOHN E. BUOKLIN. Witnesses:
