ADJUSTABLE TABLE.

SPECIFICATION forming part of Letters Patent No. 646,657, dated April 3, 1900. Application filed 11116 2, 1899. Serial No. 719,100- (No model.)

To t whom it may concern:

Be it known that we, HUGH FRANK FINNE- GAN and ALLIE J. S. MEL'ION, citizens of the United States, residing at Louisville, in the county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Adjustable Tables, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to adjustable tables, and particularly to a table adapted for use as an embalming-board or for surgical purposes.

The invention has for an object to provide a novel construction of means for rendering both the table and head and foot sections adjustable in unison and independently of each other.

A further object of the invention is to provide a novel construction of folding-brace which permits the table to be folded into a very small and convenient space for transportation or storage.

The invention also has for an object to provide an improved structure of canopy-support which is also capable of being folded.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features'thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan of the table. Fig. 2 is avertical longitudinal section. Fig. 3 is an end View of the table. Fig. 4 is a detail showing the folded position of the canopy-support, and Fig. 5 is a vertical section illustrating the retaining-ratchets for the vertically-adj ustable sections of the stand ards.

Like letters of reference indicate like parts throughout the several figures of the draw- Ings.

The tableAis shown as formed of two sections connected together by the hinges or pivots A at the meeting ends of the side frames A while the opposite ends of these frames are connected together by head and foot pieces A Within this frame the head-section Bis pivotally mounted a stationary sec tion 13 adjoins the same, and a pivoted footsection B is also mounted therein in any desired m'anner-for instance, by means of a hinge B mounted upon a cross-piece B while the head-section B is shown as carried by links B, pivoted to the opposite side pieces A The frame A- is supported by means of standards C,into which a telescoping standard 0 is introduced. This extensible member 0' is provided at its upper end with a cross-bar C the opposite ends of which are pivotally mounted in the sides of the frame-for instance, by means of boxes 0 Into the upper portion of the extensible member 0 a headpost C is introduced and adj ustably held. Any preferred means may be used to retain these parts in their adjusted positions; but we have illustrated a desirable form comprising ratchet-teeth 0 upon the extensible standard 0 and head-post C cooperating with springpressed or gravity pawls C, mounted upon a relatively-fixed part. The upper end of the standard 0 is slitted and exteriorly threaded. Upon this thread a tap or nut C is adapted to run and compress the standard into contact with the extensible member, thereby clamping the parts in their adjusted positions. If this nut be removed, it would be obvious that the table can be vertically adjusted and held by the pawl, while. by releasing the pawl from the ratchet-teeth either or both ends of the table may be lowered, as desired. The head-section B ispivotally connected to the cross-bar C from the head-post O by means of a link 0 pivotally connected to both the head-section B and the cross-bar C of the head post. This is preferably formed of wire of the structure shown in Fig. 3, whereby an extended support is obtained upon the under side of the head-rest, as at O and upon the head-post, as shown at O. The lower end of the standard 0 has pivotally connected thereto opposite feet 0 by These feet are promeans of a cross-bolt (J vided with a shoulder O to limit their upward movement, but may be folded downwardly into the position shown by dotted lines in Fig. 3 and by full lines in Fig. 4, and are therefore capable of being readilypacked in connection with the other members of the table.

The standards at the opposite ends of the table are connected together by a brace-rod D. The central member of this rod is composed of tubular sections D, pivoted together at D and slitted at their open ends. The exterior surface of the tube at the slitted portion is threaded, and upon this thread a nut D is applied, which compresses the tube and clamps the same upon the pivoted sections D carried by a collar D secured to each of the standards. The pivotal connection D permits an upward movement of the ends of the tubular section, while the telescoping parts D passing within said sections, permit the complete folding of the members in connection with the table, as the joint D lies immediatelybeneaththejointA. Theparts, however, may be held rigidlyin their adjusted positions by means of the clamping-nuts D", which prevent slipping or telescoping of the members D and D. At the head and foot of the table, or the opposite ends, afolding canopy-support E is applied. This support is provided with members E, pivoted at one end to the table and at their opposite ends to links E these links being provided with stop-lugs E to prevent the same from breaking joint in a downward direction. When it is desired to fold the canopy-support, the members E lie substantially parallel with each other, while the links E are disposed between the same, and said parts are all supported upon asuitable pin E projecting from the end of the table. At one end of the table a foot-rest F has been provided and is shown partially removed in Fig. 1. This rest is to prevent slipping or sliding of the body upon the table when the table is sus tained in an inclined position, and the rest is provided with legs F, adapted to enter recesses F at one end of the table to support the rest in proper position. It will be obvious that the table maybe covered with any desired material-for instance, a perforated or ventilated material, as shown, applied to the sections 13, B, and B It will be seen that this structure of table is particularly adapted for use in embalming, surgical purposes, and hospital or field serivces, as the same can be adjusted to any desired position suitable to maintain the patient in the most comfortable attitude, while when the table is not in use the parts can be conveniently folded or nested into the smallest possible space, thus rendering the same easy of transportation, particularly in connection with military expeditions, and from place to place, as necessary when used as a cooling or embalming table.

It is obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is
