ADJUSTABLE TABLE.

Specification of Letters Patent.

Patented June 27, 1911.

Application filed March 28, 1910. Serial No. 551,933.

To all whom it may concern:

Be it known that I, EDWIN L. GODING, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented an Improvement in Adjustable Tables, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to tables and like articles of furniture, and it has for its object to produce a table the top of which may be adjusted up and down with relation to the legs so that the height of the table may be varied at the will of the user.

To the above ends my invention consists of the improved table and devices and combinations of devices which will be hereinafter set forth.

My invention is shown in the accompanying drawing in which:

Figure 1 shows a longitudinal sectional view of a table embodying the invention. Fig. 2 shows an under side plan view of the top portion of the table detached from the legs this view being somewhat reduced in size as compared with Fig. 1. Fig. 3 shows a top plan view of the leg portion of the table. Fig. 4 shows an enlarged detail illustrating a modification of the adjusting dogs and Fig. 5 shows an enlarged detail with the adjusting dog pivoted to the top portion of the table instead of to the leg portion.

Similar reference characters will be employed throughout the specification and drawing to designate corresponding parts.

In the drawing 1 indicates the top member of the table and 2 the leg member, and as shown in the drawing the top member and leg member are fittedtogether in such a manner that the top member may be raised and lowered with relation to the leg member to secure a vertical adjustment of the height of the table. The top member comprises a table top 3 which has upon its under side a depending rectangular guide frame 4, the frame 4 being constructed of the end pieces 5 and the side pieces 6, the whole secured to the under side of the table top in any suit- .able or convenient manner. and forming a rectangular guide frame of less dimensions than the top of the table.

The leg member of the table comprises a rectangular frame formed of the ends 7 and sides 8 and is slightly larger than the guide frame 4, and within which said guide frame is arranged to fit as shown clearly in Figs. 1 and 4, of the drawing.

The end pieces 7 and the side pieces 8 of the leg member 2 are secured together at their meeting ends in any suitable or convenient manner, and Within each angle or corner there is secured a leg or post 9 of a height corresponding to the usual height of the legs of an ordinary table.

As will be apparent from the foregoing description and an inspection of Fig. 1 of the drawing, the top member 1 is fitted to the leg member 2 so that its guide frame 4 is received within and embraced by the frame of the leg member, and when the top member is lowered and rests upon the upper surface of the leg member, the table will be of the usual and normal height.

It is desired in some instances to elevate or raise the table top to produce a table of a height somewhat higher than the normal and usual table. For this purpose the top member of the table is arranged to be moved upwardly with relation to the leg member, and to be firmly and rigidly supported in its elevated position. For this purpose I have provided at each end of the table the adjusting dogs 10, there being four of such dogs, one being pivoted as at 11 to the inner surface of each of the legs 9 or these being pivoted to the frame 4 in the modification of Fig. 5, and preferably the pair of dogs at each end of the table will be connected so as to move together, by means of a rod 12 which extends laterally at the ends of the table between the pair of dogs, as shown clearly in Fig. 3 of the drawing. The dogs 10 as shown in the drawing are angular in shape, somewhat approximating a bell crank lever, having an arm 13 and an arm 14, and the pivot 11 being at the angle connecting the arms, and the dogs are preferably mounted so that the arms 13 extend inward toward the center of the table, while the arms 14 extend upward parallel with the legs or posts 9.

The arms 14 are provided with a series of steps or stops 15 at varying heights above the pivot 11, there being three such stops shown in the drawing, and with which the lower edge of the end pieces 5 of the rectangular guide frame 4 are arranged to be engaged as shown in Fig. 1 of the drawing,

whereby the top member 1 will be supported in an elevated position upon the leg member.

In order that the extreme upper stop 15 may be brought into use, and positioned beneath the end pieces 5 of the rectangular frame 4, said end pieces 5 are formed some what narrower than the side pieces 6, so that the lower edge of the end pieces 5 will be higher relatively to the lower edges of the side pieces 6, and the lower projecting ends 16 of these side pieces 6 act as cleats or stops in position to engage with the upper end of the pivoted dogs 10 so that said dogs will be stopped in their inward rocking movement by their upper ends coming in contact with the cleats or stops 16, with the extreme upper stop beneath the edge of the end pieces 5 of the rectangular frame 4:. Also the arms 13 of the pivoted dogs 10 will be provided with stops 17 (see dotted lines Fig. 1,), arranged to engage with the legs 9 to limit the inward movement of the arms 14; of the dogs 10.

From the foregoing it will be understood that the top member of the table may be rested upon the leg member to provide a table of the usual and normal height, and that it may be raised to produce a table of varying heights, and supported at either end in a firm and rigid position by the pairs of adjusting pivoted dogs.

If desired, in order to finish the table and hide to some extent the adjusting devices, the table top may be provided with a second depending frame comprising the end pieces 18 and the side pieces 19 secured to the under side of the top 3 and parallel to, and inclosing the guide frame 4, and between the respective frames I may provide the spacing bars or cleats 20 secured to the under side of the table as by the screws 21 or in any other suitable or convenient manner.

As shown in the modification in Fig. 4 the pivoted dogs 10 instead of having the angular steps or shoulders 15, may be provided with the grooved shoulders or stops 22, arranged to be engaged by a bar 23 extending between the pairs of the legs 9 and immediately beneath the end pieces 5 of the depending frame 4. By so forming the stops 22 I insure against any accidental disconnection, as the bar 23 will be firmly seated in the rounded recesses therein.

In Fig. 5 is shown a construction where the dogs 10 are pivoted to the inner surfaces of the side pieces 24, of a rectangular frame secured to the under face of the table top 3 with the notched or stepped arm 14 of the dog extending downward, and engaged with and resting upon the upper edge of the end pieces 7 of the leg portion, this being a mere reversal of the arrangement shown in Fig. 1.

While I have illustrated and described my invention as applied to a table, and more particularly to a table generally known as a kitchen table, I would say that it is equally applicable to chairs and piano benches as will be perfectly obvious to those skilled in this art.

Having described my invention I claim as new and desire to protect by Letters Patent:

1. A table, comprising a top, a separate base, a pair of dogs pivoted at each end of one of said members having a series of ledges fixed relatively to one another at different heights and adapted to rest upon the other of said members, each pair of dogs having a common operating device extending therebetween whereby they may be simultaneously manipulated.

2. A table, comprising a top having a depending frame, a separate base having a frame and depending legs, a pair of dogs pivoted at each end of one of said members, each dog having a series of ledges fixed relatively to one another at different heights and adapted to rest upon the frame of the other of said members, each pair of dogs having a common operating device extending therebetween whereby they may be simultaneously manipulated.

3. A table, comprising a top, a separate base, a pair of dogs pivoted at each end of one of said members, each dog having a series of ledges fixed relatively to each other at different heights and adapted to rest upon the other of said members, said dogs being constructed to normally bring said ledges into engagement by gravity and each pair of dogs having a common operating device extending therebetween whereby they may be simultaneously manipulated.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
