UNITED STATES MARVIN MILLER, 0F BALTlMO'RE, MARYLAND,

ADJUSTABLE TABLE.

Application led July 17,

To all 107mmy may concern.'

Be it known that I, MARVIN MILLER, a citizen of the United States of America, residing at Baltimore, vcounty of Baltimore City, State of Maryland, have invented certain new and useful Improvements in Adjustable Tables; and I do hereby declare that the following is a full, clear, concise, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in adjustable tables, having for an object to provide a simply designed and strongand durable table capable of having the top thereof adjusted vertically and angularly, the table, because of its construction, being advantageous for use in drawing or painting, and with further adjustment, as a card, writing, or dining table, the same being constructed in practically its entirety, from vwood and hence, of a pleasing and'ornamental appearance.

It is likewise an object of the invention to provide a table of the character mentioned wherein the supporting column thereof is constructed in a novel manner, avoiding the presence of fastening'devices'upon the exterior surfaces thereof to a great eX- tent. Y

Other objects of the invention will be in part obvious, and in part' pointed out hereinafter. l

In order that the invention and its mode of operation and use may be readily understood by persons skilled in the art, l have in the accompanying illustrative drawings, and in the detailed following description based thereupon, set out one possible embodiment of the same.

In these drawings Figure l is a perspective view ofthe improved table showing the top thereof adjusted to an inclined position;

F igurelv 2 is a. vertical section through the same;

Figure 8 is a fragmentary detail in section showing the manner in which the supporting ledge is adapted to be attached to the table top proper;

Figure 4 is a transverse section taken on the line 4 4 looking in the direction in which the arrows point;

Figure 5 is a fragmentary detail partly 1924. Serial No. 725,593.

in section showing the manner in which the adjustable table top 1s secured in its various adjusted positions; and,

Figure 6 is al transverse section through the supporting column of the table having the different parts thereof shown disassembled but in their relative positions.

Having more particular reference to the drawings, in connection with which like characters of reference will designate corresponding parts throughout, the improved table may bei stated to comprise a vertically disposed hollow supporting column l, which as will be noted, is composed of a plurality of pieces indicated by the numerals 2 and 3, the pieces 2 being of widths greater than the pieces 3 and being adapted to be arranged in that opposed relationship as is clearly shown in the Figure 6; the pieces being interposed therebetween and having their marginal portions arranged adjacent to the outer portions of the inner surfaces of said pieces 2.

To support the column l in its vertical position, legs generally indicated by the numeral 4 are provided, and as will be noted, have the upper portions thereof cut to flushly engage the intermediate portions of the adjacent pieces 2 and 3, whereupon screws Vor other similar fastening devices indicated by the numeral 5 are passed through the adjacent pieces 2 and 3 from the inner sides thereof into engagement with portions of such legs 4, thereby firmly securing the same in fixed position with respect to the column l which is then completed vby passing screws or other suitable fastening devices 6 through the outer portions of the pieces 2 into engagement with adjacent portions of the intermediately disposed pieces 3. By this novel mode of construction, it will be understood that a hollow supporting column, such as indicated hereinbefore, by the numeral l, substantially square in cross section, will be provided. The lower 'end of this column l is adapted to be arranged slightly above the lower ends of the legs 4, whereby the legs will serve to firmly support the completed table.

Telescopically engaged in the hollow supporting column l is a supporting post 7 havi-ng a suitable form of. bearing 8 secured to the upper end of the same through which a horizontally positioned bearing rody 9 is passed. To secure this post 7 in adjusted poico sition with respect to the column 1 receiving the same, apertured bearing plates 10 are secured to certain ofthe sides of the column l. by suitable fastening devices, whereupon locking or adjusting screws 11 are turned into engagement therewith, the inner ends of these screws being adapted to have binding' engagement upon adjacent portions of said post 7, as is clearly indicated in the Figure 2. Because of the engagement of the locking screws 11 with the adjacent portions of the sides of the supporting posts 7, it will be understood that a positive lock will be provided whereby said post 7 will be rigidly secured in an adjusted position with respect to the column 1. Furthermore, it is to be noted in this connection that the bearing plates 10 receiving the locking screws 11 are arranged in different horizontal planes and therefore, it will be appreciated that when the post 7 is raised to the full extent of its upward adjustment, a positive connection may be effected as between the same and the column 1 through the several right angularly arranged locking screws 11, hence preventing wobbling or vibratory movement of the post 7 or of the table top arranged thereupon, hereinafter more fully described. This is particularly true because of the fact thatthe lower extremity of the post 7 which will be in a position in proximity to the upper end of the column 1 will be positively engaged by the lowermost locking screw 11, while the remaining locking screw will engage the opposite sides of said post.

I may and preferably do arrange a metal binding strip or bracing band 12 about the outer side of the upper portion of the column 1 whereby to avoid any possibility of disjointure as between the pieces 2 and 3 constituting such column, hence ensuring proper reception of the post 7 in such column'at all times.

The top of the improved table comprises a suitably shaped board or piece indicated by the numeral 13, the same being herein shown to be of rect-angular formation, although, of course, it is to be understood that the size and shape of the same, may be varied, such as conditions or preference may dictate. Transversely disposed bracing bars 14 are engaged with the under sides of this table top 13, preferably in proximity to the opposite side portions thereof, as shown in the Figure 1 and have bearing brackets 15 secured to the intermediate portion thereof, as indicated at 16, said brackets having screw threaded openings formed in the outer ends or extremities thereof adapted to re ceive locking screws 17 therethrough. The opposite ends of the bearing rod 9 are rotatably engaged' in openings formed in the inner sides of the several bearing brackets 15 and by adjustment of the screws 17, it will be understood that the table top 13 may be positively secured in an adjusted position with respect to the post 7, it being understood in this connection that the rod 9 is nonrotatably secured in the upper end of the post 7 in the bearing 8, preferably by passing a pin 18 diametrically through the same and anchoring or otherwise securing the opposite extremities thereof in adjacent portions of the upper end of said post 7 as shown in the Figure 2.

If desired, a receptacle 19 may be provided` the table 2 being carried upon an arm 20 which in turn is pivotally secured to the under side of one of the bars 14., as indicated at 21. Thus, the receptacle 19 may be swung outwardly when it is desired to use the same, or inwardly'under the tablek top` 13, when it is not `in use.

Also, when the table top 13 is arranged in its inclined position, or at those times when it is desired to provide one marginal portion of the same with a supporting ledge, T have provided an angular strip indicated in its entirety by the numeral 22, said strip having openings formed in the basal portion thereof adapted to receive locking screws 23 therethrough, such locking screws having the free portions of their respective screw threaded shanks engaged in nuts 24C fixedly arranged in openings 25 formed in the adjacent portions of the under side of the table top 13. Thus, when the ledge 22 is not in use, the same may be removed from that position as shown in the Figure 2, the locking screws 23 engaged with the same and then turned into engagement with their 'respective nuts 24 fixedly arranged in the openings 25 in order that such ledge will assume that position as shown in the Figure 3, whereat it will not interfere Vwith the desired usage of the table. Y

From the foregoing, it will be understood that I have provided a simple, yet highly practical form of adjustable table which may be successfully used for various purposes, amongst which may be noted its usage as a drafting or painting table, a card table, a dining table, or asa display stand. The top 13 thereof, as hereinbefore stated, may be adjusted vertically through the medium of the. telescopically engaged post 7 received in the hollow supporting column 1 and then secured in such adjusted position through the medium of the locking screws 11, while the top 13 thereof may be angularly adjusted with respect to such supporting column 7 by rotation of the bearing brackets 15 upon the opposite extremities of the fixedly mounted rod 9; the locking screws 17 serving to secure such table top 13 in a iixed position subsequently to the secure ing of the desired adjustment of the same.

Manifestly, the construction shown is capable of considerable modification Vand ice such modification as is Within the scope of my cla-im, I consider within the spirit of my invention.

I claim A table comprising a vertically disposed hollow supporting column, said column being formed of a plurality of oppositely disposed pieces, certain of which are arranged intermediately of others thereof, legs secured to the intermediate portions of said pieces, fastening devices passing through said pieces from their inner sides into engagement with adjacent portions of said legs, other fastening devices passing through certain of the opposed pieces into engagement with the adjacent portions of the intermediately disposed and opposed pieces, bearing plates secured in different horizontal positions upon certain of said pieces and in proximity to the upper eX- tremities thereof, locking screws turned into engagement with the screw threaded openings in said bearing plates and passing through openings formed in the adjacent portions of their respective pieces of the column, a supporting post telescopically engaged with said Supporting column,- a horizontally positioned rod immovably secured adjacent its intermediate portion in the uppery end of said supporting post, atop, bearing brackets secured to the under side of said top and adjacent the opposite ends thereof, said bearing brackets having inwardly disposed openings formed therein and their outer sides closed, 1ocking screws passing through screw threaded openings in said bearing brackets and adapted to be engaged with adjacent portions of said rod, and a right angularly formed ledge adjustably secured to the under side of said top adjacent one marginal portion of the same.

In witness whereof I have hereunto set my hand.

MARVIN MILLER.
