IGNAZ WEINGAERTNER, OF ST. LOUIS, MISSOURI.
To aZZ'who'm it may concern:
Be it known that I, IGNAZ VVEINGAERTNER, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Tables, of which the following is a specification.
My invention relates to improvements in tables and has for its object to provide a portable table having a number of adjustments hereinafter described, and provided with an electric lamp.
In the drawingsFigure-1 is a front elevation of a device embodying my invention. Fig. 2 is an end elevation of the same. F 3 is an enlarged detail view of the vertical adjustable bracket employed in the device of my invention, showing the tubular portions in longitudinal mid-section. Fig. 4t is an enlarged plan view of the ratcheted adjusting wheel employed in the device of my invention. Fig. 5 is an enlarged detail plan view of the mechanism whereby the halves of the table are rendered capable of separate adjustment. Fig. 6 is an end plan view of the table, showing one of its halves horizontally adjusted, the opposite half adjustcd atan angle for reading or similar purposes, and illustrating the adjustment of the electric lamp for use in connection with the inclined half of the table.
As illustrated in the drawings, I employ a horizontal base member 7 provided at one of its ends with the cross-bar 8, which is, in turn, supported by the casters 9. At its opposite end the supporting member 7 is connected with the tubular upright 10 whose base is supported by the forked support 11. Upon the tubular upright 10 I provide a cylindrical sleeve 12. Near its bottom the cylindrical sleeve 12 is provided with an opening 13 in which the friction cam 1d is pivotally mounted by means of a pin 15. The cam 14 is provided with the lever arm 16, at the outer end of which I provide a counterbalancing weight 17 which serves to keep the cam lt normally in contact with the upright 10, to lock the sleeve 12 in position. The sleeve 12 is provided with a socket 18 in which the pipe 19 is horizontally and rigidly mounted. The tube 20 is rigidly mounted upon the Cpipe 19, and the tube 21 is loosely mounte upon the tube 20, and carries at its inner end the flanged collar 22. On periphery of the flange of the collar 22 is provided slotted recesses 23, 2 1, 25, 26 and 27, to permit of several adjust- Specification of Letters Patent.

inents by reason of the engagement with said slotted openings of the locking bar 28, which is pivotally mounted upon the sleeve 12 at the point indicated by the numeral 29, and whose movements are controlled by the tinger-catch 30.
The upright 10 is provided with a reducing plug 31 in which the lamp-post 32 is slidably mounted, its vertical adjustment being controlled by the thumb-screw 33. In the top of the lamp-post 32 I provide a horizontal wire-conveying tube 31, whose horizontal and rotary adjustment is controlled by means of the set screw 35, and which carries at its outer end the depending electric lamp 36.
In the construction of the table I employ the two table sections 37 and 38 of equal dimensions. Upon the outer edges of the sections 37 and 38 I provide the hinged bars 39 and 40, which are mounted upon hinges 411 on the lower surface of the table sections 37 and 38, and which are locked in position by means of the latch 4-2. The functions of the bars 39 and 10 being to serve to lock a table cloth in position upon the table, or to serve, when one or both of the table sections 37 and 38 are inclined for use as a reading table or drafting table, as a book rest or support for a drafting board (see Fig. 6), in which position the lamp 36 may be thrown into proper alinement with the surface being used for reading or drafting purposes (see Fig. 6).
The inner ends of the table sections 37 and 38 are mounted upon the tube 21 by means of hinges 43, whose inner ends are in the form of collars 14: mounted loosely about the pipe 21. Similarly constructed hinges 15* 15 are used to support the outer ends of the table sections 37 and 38, and are loosely mounted upon the exterior of the pipe section 20.
To secure the independent adjustment of the table sections 37 and 38, I employ the construction which is illustrated in detail in Figs. 5 and 6, and which may be described as follows: The hinge-bar 16 is secured at the points indicated by the numeral 47 to the lower face of the table section 37, and
is provided at its inner extremity with the collar 18 loosely mounted upon the pipe section 21. The hinge-bar 19 is similarly secured at the points indicated by the numeral 50 (see Fig. 5) to the lower face of the table section 38, and terminates at its inner end in the collar section 51, which is loosely mounted upon the pipe section 21. Upon the outer end of the pipe section 21 and around its periphery I have mounted the collar 52 carrying the yoke 53 (see Fig. 6).
adjustable vertically on the upright 10; the.
table being composed of halves 87 and 38 which may be both adjusted to horizontal position or to any deviation from the hori-.
zontal that may be desired, and which are capable of being both swung into a vertical plane as illustrated in Fig. 1. The edges of the table are provided with the described clamping means for holding a table cloth tightly in place upon the table, or to serve as a rest for a drafting board, or books of reference; the table being provided with an electric lamp which is adjustable vertically or horizontally, in order to accommodate itself to the angle occupied by the table or its halves.
Havin thus fully described my invention, what I c aim as new and desire to have secured to me by the grant of Letters Pat ent, is:
1. In a table, the combination of a base; a vertical upright carried by the base; a sleeve slidably and rotatably mounted upon said upright support; a friction cam for looking said sleeve in place upon said support; a horizontal supporting member carried by the sleeve; two table sections independently hinged upon said horizontal support; hinged bars mounted upon the outer edges of said table sections, slotted segmental 'uides and screws for locking the table sections in set position, substantially as described.
2. In a table, the combination of a base; a vertical upright carried by the base; a sleeve slidably and rotatably mounted upon said upright support; a friction cam for locking said sleeve in place upon said support; a horizontal supporting member carried by the sleeve; two table sections independently hinged upon said horizontal support; segmental slotted guides and screws for locking each of said table sections in position; and hinged bars mounted upon the outer edges of said table sections, substantially as described.
3. In a table, the combination of a base; a vertical upright carried by the base; an elongated sleeve slidably and rotatably mounted upon said upright support; a friction cam for locking said sleeve in place upon said support; a horizontal sup )orting member carried by the sleeve; two ta 1e sections independently hinged upon said horizontal support; hinged bars carried by the table sections for supporting the articles placed thereon; a slotted segmental guide carried by each of the table sections whereby the table section is supported at any set position, substantially as described.
In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
