UNITED STATES PATENT OFFICE;
FORREST E. RUGER, OF BINGHAMTON, NEW YORK, ASSlGNOR OF ONE- HALF TO FRANK A. BLAKSLEE, OF BIN GHAMTON, NEW YORK.
Specification of Letters Patent.
Patented April 24, 1906.
Application filed June 19,1905. Serial No. 265,976.
1'0 all whom it may concern.-
Be it known that I, FORREST E. RUGER, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented new and useful Improvements in Clamps for Book-Supports, of which the following is a specification.
This invention has for its ob'ect the provision of contrivances attachable to and adjustable from a garden, conservatory, or other easy or reclining chair, and made 1nterchangeable and adjustable with means for the support of pa er, music, books, and articles of different inds, and also providing chairs of the kind mentioned, as well as other chairs, with a standard to which may be secured brackets and devices for the attachof the screw f, all as will be clearly underment and support of trays and other devices of a cognate nature that may be adjusted to various positions to suit circumstances. a
The nature and character of my improved chairs will appear from the following specification and drawings, in Figure 1 of which the chair and its attachments are fully disclosed and the principal bracket is shown in perspective as applied in position. Fig. 2 1s a view somewhat similar to Fig. 1, but showin the brackets as supporting a single tray and its equipments. Fig. 3 is a perspective view of the bracket-supporting standard alone.
' Fig. 4 is a perspective view of means for supporting a tray, the latter being represented partially in section, the better to portray its construction and the means for supporting it.
In the drawings, A designates the clamp for fastening the invention to the arm and seat of a chair. The said clamp is com osed of two members 1 and 2. The mom or 1 consists of a vertical bar a, having an an lar projection b at its lower end, which is a apted to extend under the seat 0 of the chair, and
is provided on its upper side with a pad or iece of felt d, so as not to mar the furniture.
xtending outwardly from the lower end of the clamping member 1 is a boss or heelpiece 2, having a hole formed therethrough through which a screw f extends. A knob g is pinned on the lower end of the screw f, and a stud 7t extends laterally therefrom just above the heel-piece, so that the screw may beturned by the knob.
The member 2 consists of a vertical bar i, the inner face of which is'flat, so that the bar a may slide easily up and down thereon, and
the up r end of the bar is provided with latera y-projecting arms 7; Z, each of which is provided with a pad m on its under side, so
' as not to injure the arm of the chair to which it is attached. The arm 7' extends over the arm of the chair, while the arms k l project along the side of the same.
The lower end of the member 2 is provided with a combined nut and slide B, the nut being an enlargement m on the extreme lower end of said member and bored and threaded for the reception therethrough of the screw The slide B comprises pieces of metal integral with the enlargement m, engaging the flanges 0 on each side of the member 1, so
that the two members may be kept together as one is adjusted upon another by the action stood.
In applying or clamping the improvement to a chair which is presupposed to have an arm the member 2 will have its lateral arm 7' at the top caught over the arm of the chair with the other two arms 7c Zprojecting along the side thereof, and the projection .b ,at the lower end of the member 1 will be arranged so as to extend under the seat of the chair. With the parts in this position the knob g of the screw ,1" will be manipulated so as to bring the projecting parts b and and 2, really constituting 0 amps, together on the arm and seat of the chair, clamping it securely in position thereon. It may be released by turning the screw in the opposite direction.
The two arms 7c 1, extending in opposite directions from the clamping-arm 7', operate horizontally against the edge of the arm and keep the entire device between the arm and will be readily understood by those skilled in,
the arts. For the reasonsstated, the arms,
k I become important features of my improvments. The foregoing devices form a clamp that may be readil attached to a chair for an orting a brac et and other means for hol mg a tray and book, paper, and music sup:
j of the members 1 The seat. of the chair and arm of the latter have been chosen as the means for attaching my lmprovements thereto, for reasons inter alia, that they are of the most substantial structural features of the chair and they bring the book-support up to a relatively high point, two matters "of obvious importance. The arm and chair seat therefore become very important factors in the improvements which any other two members of the chair will not answer, unless they possess like properties or ualities of position or place, and firmness and rrgidity, among other things, as well.
At the top of the member 1 there is an enlargement 0, through which is formed a hole vertically for the passage of the main rod p, which may be clamped or fixed in any position in which it may be placed by, a set-screw The upper portion of the main rodp may be bent at right angles to the lower or main portion, and the angular part of the main rod may be provided on its end with a coupling 1, through which a rod a: similar to the main rod, may be. passed and fixed in place by a setscrew 8.
U on the rod m, which need not be of angular orm, but of any-shape needed or fancied,
- a book-support, tray or other means 0 may be secure In Fi 4 I have shown a book-su port C, provide on its back with a rounde plate t, adapted to be secured to the back by screws a, with which plate there is integrally connected a rod-support '0, having a hole a little larger than the rod formed through it'for the reception of the latter and a thumb set-screw 'w tapped therein to fix the rod in place. In this case a short angular rod 00 is secured to the back of the book-support, and to this short angular rod another short rod 1], curved in form, is connected by means of a coupling 2, and this latter rod y is attached to the main book-supporting rod as at any point turned to any position desired. To enable the hole formed through the rod-support 'v to be made a little larger than the rod w passing through it, I form a boss, as it were, on the extension '0 and rovide thimble-like parts to extend in line with said hole on opposite sides of the rod-support, as shown.
Each book-support, tray, or other means to be carried or supported by the invention will have a plate and rod-supporting means like that described attached to its back. Furthermore, each book-sup ort, tray, &c., will be attached either imme 'ately to the rod 10 or mediately by means of short rods, straight or bent.
As shown in the drawings, the book-sup:
them.
It is obvious that in use I am not confined to a book-support ard tray, since any other means of a similar nature may be supported on the rods.
The chair may be of the reclining or other type, the only necessary structural characteristic being that it shall have an arm or other means which will permit of the application of a clamp, as stated-that is, to both the arm and seat, so as to secure a firm connection with the chair and obviate the liability of the clamp swinging around out of place when more than nominal force is applied to the book-sup orting means. In securing these ends the ength of the slides 1 and 2, which is long, and the lateral extensions k and Z along the side of the arm of the chair contribute an important part.
. I claim 1. A clamp for a book-support, consisting I of two members, one being provided with a padded extension to project over the arm of the chair and two similar extensions to project along the sides-of the arm, and the other member being provided at its lower end with a padded extension to project under the seat of the chair, an adjustin -screw connected with one member, and a sh e operatively connected with the screw, whereby, through the medium of the latter'the two members may be clamped upon a chair. I
2. A clamp for a book-support to a'chair consisting of two relatively long members, each provided with a bar to slide one upon the other and provided with clamps, one engaging. the arm and the other the seat of a chair, the bar of one member having flanges upon its sides, and the other member being provided with a combined nut and slide, the
sides of the latter slide extending beyond the 7 side edges of the said flanges, in combination with a screw tapped through the said nut and being prevented from moving longitudinally with the slide with which it is connected.
3. A clam for a book-support'to a chair consisting '0 two" relatively long members, one provided withv a padded extension to ex tend under the chair-seat, and the other having padded extensions to engageand extend over the arm of the chair and padded lateral extensions projecting in op osite directions from the first-named padde extension along the side of the arm, a screw extending longitudinally with the connections of the clamps and operatively connected therewith to secure the clamps to the chair and to release them therefrom, and a knob on the lower end of the screw to operate the same.
4. The combination, with a clamp for a book-support to a chair, said clamp consisting of two members-a lower member adapted to engage the seat of the chair, and an upper member provided with a clamp to extend over the arm of the chair, and having lateral extensions projecting in opposite directions along the side of the arm, an enlargement on the upper clamp, a hole extended through the said enlargement, a rod passed through said hole, a set-screw tapped into said enlargement and adapted to engage said rod, of a coupling on said rod, a rod passed transversely through the said coupling and a set-screw in said coupling to engage the said last-mentioned rod, and a book-support attached to the latter rod.
5. A clamp for securing a book-support to a chair, consisting of a clamping member to engage the seat of a chair, a second clamping member to engage the arm of the chair, hav-. ing a part adapted to extend over and upon the arm and lateral extensions rojecting in opposite directions along the si e or edge of the arm, each of the said lateral extensions being equal or more than equal in length to the horizontal clamping ex'tension projecting over and upon the upper surface of the arm, combined with book-trays and means connected with the top clamp on the chair-arm extending substantially horizontally therefrom for supporting the trays.
6." A clamp for securing a book-support to a chair, consisting of a clamping member to engagethe seat of a chair, a second clam ing member to engage the arm of the chair, av
ing a part adapted to extend over and upon clamp on the arm and extending substan tially horizontally therefrom for supporting the said trays.
In testimony whereof I allix my signature in presence of two subscribing witnessses.
