IINTTED STATES PATENT EETCE.
JAMES C. I. VILSON, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 598,689, dated February 8, 1898 Application filed March 3l, 1897.
To a/ZZ whom t may concer-m Be it known that I, J AMES C. I. WILSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Type-Vriter Copy-Holders, of which the following is a specification.
My invention relates to an improvement in the class of copy-holders carried by jointed brackets, through the medium of which they are adapted to be attached to type-writing machines and swung thereon for their adjustment to different positions.
More particularly stated, my invention in the class of copy-holders referred to relates to improvement of the features of the springclamp for holding the copy (book or sheet) and a leaf-clamp adjunct.
The accompanying drawing shows my irnprovement by a perspective view as operatively applied to a type-'writing machine, of which abroken portion is represented.
A is the support for the copy, which I prefer to form of the construction illustrated. The construction shown of the support A is as follows: From the opposite ends of the rear edge of a ledge r there project upward the single sockets r and r2, and from the same edge,at a point midway between the end sockets, there projects upward the double socket frs. An adequately stiff Wire p is bent upon itself into the shape of a rectangle to form one half of Vthe back of the support, with one end fastened in the socket r/ and the other end fastened in one of the holes of the socket r3, and the length of this wire forming a side of the support is bent near its upper end to form a laterally open bearing-loop o for a purpose hereinafter described. A similarly-bent wire 4o p forms the other half of the support by having one end fastened in the socket?12 and the strips p2 and p3, which may be formed of thin Serial No. 630,142. (No model.)
sheet metal. The parts p, p, p2, and p3 thus form the back of the copy-support.
B is a clamp which may be formed out of a single length of adequately stid wire,atford ing the straight rod portion n or back of the clamp, at which it is journaled in the loops o and o', the handle n, by which to manipulate the clamp, the forwardly-bulging vertical shoulders 71,271.2, and the clamping-arms n3 n3, extending toward each other from the lower ends of the shoulders along the reinforcingstrip p2, but short of the center thereof to leave them separated by a space m between their ends. A spring Z, connecting the clamp with the support A, as shown or otherwise, imparts to it yieldingly its clamping function, in performing which against the matter to be held, which is inserted for the purpose between the clamp B and the back of the copysupport A, the clamp forms a species of springjaw cooperating with the back of the support, which forms, as it were, a stationary jaw. By providing this vertically-swinging clamp with the separated clamping ends a copy-book which opens along its shorter edge and one opening along its narrower edge may be adjusted with equal facility in the clamp through the space m, and the holding effect of the clamp is enhanced by the bulging construction of the shoulders n2.
B is a resilient leaf-holding adjunct of the clamp, shown as formed of alength of springy wire bent upon itself to afford the arms i and i', connected by a back 2, at which the device is journaled in the loops o2 and o3, being sustained by a stop 5, and the arm 1l' extends at the back of the strip p2, with which it is connected, and the arm extends above and along the top of the support in position to stop from flying back a leaf or the section of `a book turned over the top of the support.
To permit turning a book-leaf 4over the top of the support,` the wire i should first be turned backward out of the way'and released to fly back after the leaf has been adjusted to obstruct or hold it against returning.
C is the supporting-bracket for the support A. It may comprise any desired number of sections jointed together to swing horizontally. As shown, the bracket is formed with four sections It, h', h2, and h3. The section h has a rigid claw f at one end, at which it fits over a lower side bar o of the frame of a type-writing machine D and upon which it is fastened by a thumb-screw f, and on the other end 'of this section is a socket g to receive the pintle e on one end of the Z-shaped section h', the opposite end of which contains a socket g to receive the pintle e on one end of the L-shaped section h2, the opposite end of which is connected pivotally with the Vertically-opening eye cl on one end of the section h3, having a horizontally projecting threaded stem CZ at its opposite end. The connection of the bracketC with the support A is made at the stem d on the section h3 by passing the stein through a horizontal opening in the lug c, projecting from the center of the rear edge of the ledge r, and clamping the parts together by means of a thumb-nut c', applied to the stem against a washer c2 thereon.
- By the described connection of the jointed bracket with the support A when the device is attached to the machine D with the support overhanging the latter the supportv may be turned down on loosening the thumb-nut c' to lie flat against the top of the machine 4and thus let the desk containing it be closed in the usual manner without obstruction from the copy-holder, which need not be detached, since it drops with the type-writing machine in closing the latter and is brought into position for use upon raising the supportA on the stem d when themachine is raised by opening the desk.
What I claim as new, and desire to secure by Letters Patent, is
1. In a copy-holder for type-Writing machines, the combination of a copy-support, a clamp hinged to said support to swing up and down thereon with relation to its front side and terminating in clamping-arms extending toward each other from opposite sides of the center'of said support and separated at their ends to afford between them a copy-insertion space, and a spring connecting said clamp with said support, the spring-controlled clamp and back of the support forming jaws coperating to hold the copy inserted between them, substantially as described.
2. In a copy-holder for type-Writing machines, the combination of a copy-.support having laterally-open bearing-loops in its opposite sides near its upper end, a clamp comprising the rod n journaled in said loops and having a handle at one end, shoulders n at its opposite ends and arms n3 extending toward each other across the face of said support and forming between them the copy-insertion space m, and a spring connecting said clamp with said support,the spring-controlled clamp and back of the support forming jaws cooperating to hold the copy inserted between them, substantially as described.
3. In a copy-holder for type-writing machines, the combination of a copy-support having laterally-open bearing-loops in its opposite sides and in one side vertically-open bearing-loops, a spring-controlled clamp B comprising the rod n, j ournaled in said laterally-open loops, a handle at one end of said rod and shoulders'n,2 at its opposite ends terminating in arms n3 extending toward each other across the face of said support and forming between them the copyinsertion space m, and a spring-controlled leaf-holder B journaled in said vertically-open loops and having an arm extending along the top of said support, substantially as described.
4. In a copy-holder for type-Writing machines, the combination of a copy-support A comprising the ledge r and back thereon formed of the bent wire p containing the loop o, the bent wire p containing the loop oand the reinforcing-strips crossing said Wires, and a spring-controlled clamp B comprising the rod n, journaled in said loops, and having a handle at one end and shoulders n2 at its opposite ends terminating in arms n3 extending toward each other along the upper reinforcing-strip and forming between them the copyinsertion space fm, substantially as described.
