Specification of Letters Patent.
Patented June 16,'l908.
Application filed March 16, 1908. Serial No. 421,336.
A further object is to provide novel means Y for holding the table in any desired position relative to the chair, said means being easily opkelrated and designed to firmly secure the ta e.
Another-object is to provide a table top which is adjustable relative to its support, said support being also adjustable relative to the chair or other structure to which it is attached. 1 l With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which pointed out in the claims. I V
In the accompanying drawings is shown the preferred form of the invention.
In said drawings: Figure 1 is an elevation of the device in position upon a chair, a porwill be hereinafter more fully described and tion of the chair being shown. Fig. 2 is any enlarged section on line a:m, Fig. 1. Fig. 3 is an enlarged sectionthrough a portion of the table top and showing the connection between it and the adjustable standard. Fig. 4 is a detail'view of one of the members of the standard gripping ball. Fig. 5 is a detail view of one of the nuts of the clamping screw and showing a'portion of the adjoining part hf the of the clamping plates.
Befern'n to the'figures by. characters of reference designates a chair or other suitable supjiorting structure, the leg a l which to be engaged by'two' op )ositely disposed gripping plates 1-1... Each-3f these plates has ws 2 and 3 at its opposite ends respectively, the jaws 2' having their working faces prefere bly covered with a lining 40f a The jaws 3 have their inner or; working faces concave and conforming tfmllstlmtially with the contour of a grippingipn 5; formed of oppositely disposed similar" arl n-spherical sections 6 each of which is} 1;:
l ill F of Tipton and State of ferabiy concave-convex and has diame;rii[al.y opposed projections and recesses 7 and 8 respectively whereby when the sections are assembled with their open faces toward each other the projections on one section will project into the recesses 7 in the prevent independent other section and thus rotation of the parts. Each ball section also has two substantially semi-circular recesses 9 in its edge which are diametrically opposed and the corresponding recesses of the two sections are designed to register when the ballv sections are assembled in the manner heretofore described.
Each plate 1. is provided between its jaws 2 and 3 wlth an elongated'angular aperture-10 and mounted to swing wi hineach of these apertures is a nut 11. having trunnions 12 extending in opposite directions fromits outer end and hearing within recesses 13 in the plate 1. Each nut is therefore capable of swinging upon these trunnions toward either of the jaws 2 and 3. Mounted within the twonuts is a clampingscrew 14 having right and left hand threads engaging the respective nuts so that when the screw rotates in one direction the nuts, and of course the plates 1, will be drawn toward each other and when the screw is rotated in the opposite di-,
rection theplates will be free to move apart.
A head 15 is located at either or both ends of the screw so that't-he same can be readily turned. The recesses'19 are designed to receive a standard 16 which may be either solid The up-f or tubular and is preferabl met 1.
per end ofthis standard as a all thereon which can be formed therewith or, as shown L in Fig. 3,- can be'made ofwood or other like material and connected thereto in asmtable manner. In-Fig. 3 this ball which has been indicated at 17, base stem 18 which enters the endoi the standard and a lug 19 projects from this stem and engages a notch 20 in the end of the standard to hold the ball and stem against accidental rotation relative to the standard. V
The table top 21- may be of any preferred construction and is preferably provided on its bottom face with cleats 22 to which a plate 23 is connected, ,said'plate having a socket 2.4 in its lower face designed to receive the ball 17. This plate has ears 25 formed thereon and connected by a pin 25. detach ably engaged by a book 26 extending from a ring 27. The inner face oi" the ring is rounded transversel as indicated in Fig. 3 so as to surround and bear upon the lower half of the ball and support the same. A tongue 2-8 GX-' lthe leg (1 therebetween.
tends from the ring at a point diametrically opposite the hook 26 and this tongue has a wing bolt 29 for engagement with plate 23. then the bolt is tightened it will force the tongue 28 toward the plate 23 and thereforecause. ring 27 to press the ball 17 tightly into socket- 24. The parts are thus bound to gether so tightly that it will be practically impossible to move the table top 21 and.the standard 16 imlepeudentlv of each other. However, by loosening the bolt the ring 27 can be loosened whereupon the ball 17 can be moved within socket 24 until the table top has assumed any desired angle relative to the standard.
'lo fasten the attachment to the of a chair or other structure the screw 14 is turned'until the jaws 2 are moved apart a sullicient distance to permit the insertion of The standard 16 is inserted between the ball sections o and after it has been adjusted toa desired elevation and inclination the screw 14 is rotated so as to draw the plates 1 toward each other. Jaws 2 will therefore bind upon the chair legs and the jaws 3 bind upon the ball sections 6. It will be seen that, the chair leg and the standard will be simultaneously gripped. By mounting the nuts 11 upon the pivots they are free to adjust themselves to the changing angles of the plates 1 during the tightening or loosening of the parts. It is to be understoodithat ball sections 3 can be made solid if preferred and various other changes may he made in the construction of the device without departing from or sacri ticing the advantages thereof.
As shown in Fig 2 bow spring 30 is arranged betweenthe plates 1 and straddles the screw 14. The ends of" the spring bear against the plates close to the jaws 2 so as to hold them spread apart normally, and the jaws 3 gripped upon the hall 5. When the device is detached from a chair or other support the ball 5 will thus be held in position.
What is claimed is:
1. The combination with a standard having a ball thereon, a table top mounted upon the ball, and means carried by said top for clam .ing the ball to secure the top and stan ard against independent movement; of oppositely disposed standard engaging members, clamping plates, each of said plates having jaws for engaging said members and a su port res ectively, and means mounted wit 1n the p ates for adjusting the jaws relative to each other.
2. The combination with a standard and a tabletop adj ustably mounted thereon; o1 op positely disposed clamping plates, each plate raving a aw ad acent each end, semispherical standard engaging devices mounted between the jaws at one end of the plates, memscrew en 'a iiw the nuts for shiftin the;
h P b P.
plates relative to each other.
t. The combination with a standard and table top adjustably mounted thereon; of
oppositely disposed standard engaging members, clamping plates, each of said plates having aws for engaging said members and a,
support respectively, and means mounted within the plates i or adjusting thejaws relative to each other.
5. The combination with a standard and a table top adjustably mounted thereon; of oppositely disposed standard engagin members, clamping plates. each of sai plates having jaws for engaging said members and a support respecti ely, means for adjusting the jaws relative to each other, and elastic means interposed holding the aws at one end of the plate nor mally yieldingly upon the standard engaging" members.
6. In a device of the character described .a clamping and supporting attachment comprising oppositely disposed standard engagbetween the plates for mg members, clamping lates having'jaws at the ends thereof for him mg upon said members and a support respectively, nuts mounted to root: within the plates, an adjusting screw engaging said nuts for shifting the plates towardor from each other, and yieldable means interposed between the. plates for holding the jaws at one end thereof normally members. 1
In testimony that I claim the foregoing as my own, I have hereto ai'hxed my signature in the presence of two witnesses.
