PED EsTAL EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 741,049, dated October 13, 1903. Application led June 17, 1902. Serial No. 112,038. (No model.)

To all whom, it may concern.-

Be 'it known that we, JOHN LUGER, Jr., and JOSEPH MULLER, citizens of the United States, residing at North St'. Paul, in the county of Ramsey and State of Minnesota,

have invented certain 4new and useful Improveniente in Pedestal Extension-Tables;

and we do hereby declare the following to be a full, clear, and exact description of the invenro tion, such as will enable others skilled in the art to which it apporta-ins to make and use the same.

Our present invention has for its object to provide an improved means for locking to- I5 gether the sections of sojcalled pedestal extension-tables, and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

As is a well-known fact, a serions objection has been raised to the pedestal type of extension-table, due to the fact that the sections of the pedestal as well as the sections of the l table-top are liable to separate even when- 2 5 the table is notmoved about, and especially when the table is moved from place to place or is turned around or handled in any Way.

The invention is illustrated in the a'ccom-v 2 panyin g drawings, wherein like characters in- Y 3o dicatel like parts throughout the several views.

Figure 1 is a plan View showing a pedestal extension-table having our improved locking device applied thereto, parts of the table-top being broken away. Fig. -2 is a vertical secl tion taken through the table on the line to2 002 of Fig. 1. Fig. 3 is a transverse section on the line 5123x133 of Fig. 2, some parts being broken away; and Fig. 4 is a view corresponding to Fig. 2, but with parts broken away and with 4o thevsections of the table separated.

The numeral l indicates the two parts of a table-top, the numeral 2 the two sections of the hollow pedestal, the numeral 3 the extension-slides, and the numeral 4 the center leg. The` center leg 4, as is usual, is connected to the intermediate pair of slides 3 and is adapted to be inclosed within the sections ofthe pedestal 2 when the sections of the table are forced together. The pedestalsections 2, as is usual, are provided with feet 5.

One of the pedestal-sections 2 is provided within with a pair of pivoted dogs or latches a., which are pivoted to the opposite sides thereof and when the pedestal-sections are forced together are adapted to engage over pins or projections a', secured on the inner opposite sides of the other pedestal-sections. When the hooked ends of the dogs o. are engaged over the pins or lugs a', as shown in Figs. 1 and 2, they extend one on each side of the center leg 4. Within the box-like housing aorded by that section of the tabletop which moves with the pedestal-section to which the dogs a are pivoted is a verticallyoscillating frame 19, pivoted at h and carrying at its free end a horizontally-extended rod or bar 192, the ends of which project for coperation with cam-strips c, secured on the inner pair of extension-slides 3, as will hereinaftery more fully appear.

A pair of light links or rods ol connect the intermediate portions of the dogs a to the free end of the oscillating frame t. A pair of springs c, secured at their outer ends tothe bottom of one of the box-like table-top sections, engage the rod b2 at their free ends and yieldingly press the same and said frame I9 and dogs a upward, as shown in Fig. 4.. The springs e may be of wood or metal and may of course take various forms.

With the construction'so far described when the table-sections are forced together and as they closely approach the closed position the ends of the rod or bar b2 are engaged by the cam-strips c, and thereby forced downward, carrying downward also the 'frame o, links d', and dogs a. Under this movement by; the time the sections of the table-top and the sections of the pedestal are forced together the free endsof the dogs a are engaged over the ment of the same would release the rod b2 and frame b, and thereby permit the' dogs ato be again raised under the action of the springs e. The dogs a do not,therefore,actually serve as locks, but more properly as latches, which as long as held in engagement with the pins or lugs a prevent separation of the sections of the table.

To positively hold the latches or dogs CL in operative positions, we provide a secondary latch or lock proper, which in its preferred form is constructed as follows:

findicates an oscillatingstop-bracket,which at its upper edgeis pivoted within small bearings f', secured to the top board of that tabletop section which carries the oscillating frame b. The free edge or end of the stop-bracket f is mounted for engagement with the bracket b near its free end, and its dimensions are such that it can be thrown straight downward, so as to act as a lock or positive stop to said frame b only when the latteris depressed to its limit, as shown in Figs. 2 and 3, and the dogs or latches t are thrown into operative engagements with the pins or lugs c.

A sliding bar g is pivoted at its inner end to the free end ot' the stop-bracketfby means of a short bolt f2 or other suitable device. At its intermediate portion the bar gis provided with a longitudinal slot g', in which works a guide-pin g2 of a bracket g3, supported from the overlying table-top section. At its outer end the bar g is preferably provided with a hand-piece g4, which is located near one edge of the table-top, so that it may be readily reached.

It is evident that when the sections of the table are forced together, under which movement the frame b is depressed and the dogs or latches a are thrown in-to operative positions, the stop-bracket or lock b under its own gravity and that of the bar g will tend to fall into its operative position. (Indicated in Fig. 2.) 1f at any time it should not, it may be positively given'such movement by forcing the bar g inward by hand. As is evident, to unlock the sections of the table it is necessary irst to draw g outward, so as to turn the lock or secondary latch f into an inoperative position. The locking mechanism above described may be very readily applied to'pedestal extension-tables and does not require the cutting either of the sections of the pedestal or the center leg. It is of smallcost, is easily operated, and is extremely efficient for the purposes had in View. By actual usage we have demonstrated the efficiency of the device.

It will of course be understood that the device is capable of many modifications in its detailsofconstruction. Forinstance,theslid, ing bar g may take various forms and mightin fact, be in the form of a simple rod. Again, the so-called lock pins or lugs a may take various forms as long as they are adapted for coperation with latches or dogs of the general character described.

What we claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In an extension-table, the combination with a pedestal made up' of two sections, of a lock element within one of the pedestal-sections and a cooperating latch within the other pedestal-section, a latch-actuating connection carried by the same section of the table which carries said latch, and a cam on the other table-section operating on said connection to force the said latch into an operative position when the table-sections are closed together.

2. In an extension-table, the combination with a pedestal made up of two sections, of a center leg embraced by the sections of the said pedestal, a pair of latches pivoted to the opposite sides but within one of the pedestalsections, a yielding cam-actuated element connected to said pair of latches and carried by the same table-section, a cam movable with the other table-section for action on said camactuated element, to force the said pair of latches into operative positions when the table-sections are closed together, which latches extend on opposite sides of said center leg, and lock elements on the other pedestal-section with which said latches engage, substantially as described.

3. The combination with a pedestal extension-table having a pedestal made up of two sections, of a center leg embraced by the sections ot' said pedestal, a pair of latches pivoted to the opposite sides and within one of the pedestal-sections and working on the opposite sides of said center leg, a pair of projecting lock-lugs secured within and on the opposite side of the other pedestal-section for cooperation wi th said latches,a spring-pressed frame b pivoted to one of the table-sections and provided with the rods dconnecting it to said latches, and cams c carried by the other table-section and operating on a part of said frame b to force said latches into operative positions when the table-sections are forced together, substantially as described.

4. In an extension-table, the combination with a pedestal made up of two sections, of two pairs of latches mount-ed within said pedestal, one on each side thereof, the coperating latch elements being carried by different pedestal-sections, a springpressed latch-actuating connection carried by the same section of the table which carries the movable elements of the said two latches, a cam carried by one of the sections of the ta- IOO ble which has movement in respect to the table-section just noted, and operating on said latch-actuating connection to cause the same to move the movable latch element into 0perative positions, when the table-sections are moved together, and a lock mounted on the table-section which carries said spring-pressed latch-actuating connection, for action on said connection to hold said latches locked, substantially as described.

5. In a pedestal extension-table, the combination with a hollow pedestal made up of two sections, of a center leg adapted to be embraced thereby, the laterally-spaced pair of latches a pivoted within one of the pedestal-sections and projecting on opposite sides of said center leg when the table is closed up, cooperating latch elements a secured Within the other` pedestal section, the upwardlyspring-pressed lever b carried by one of the sections of the table, said frame having the projecting bar b2, the rods d connecting said latches to said frame b, the cam-strips o carried by the other table-section andoperating on the ends of said bar b2 to force said latches into operative positions when vthe table-sections are forced together, the pivoted lock f I5 overlying said frame band adapted to lock the same in its depressed position and said latches in operative positions, and a sliding rod connected to said lock fand terminating at its outer endnear the margin of the table- Y
