on c. or PHILADELPHIA, r'amtsnv 'nnracmns mam-Bonn ron smxs;

To all wkome't may concern:

for Sinks, of

Be it known that I, of the United States, residing in Philadelphia, Pennsylvania, have invented certain mprovements in Detachable Drain-Boards which the following is a specification. The object a detachable can be readil which, when without utilizing manually operated clampin means. 1 I a e invention is particularly adapted for use as a Rietachable. drain board for sinks, but it will be understood that it can be used asa detachable table, or ironing board, arranged to be secured to a wall or to a table, or desk, for the purpose of increasing the surface area. i

In the accompanying drawings:

Figural is a side view of my improved drain board showing it in.position in connection with a sink;

of my invention isv to construct dramboard or table which applied to a fixed object and .Fig. 2 is a view,'similar to Fig. 1, showing the method of applying the board to a sink; a

Fig. 3 is an inverted the drain board;

Fig. 4 is an inverted the spring OIBJDCPS;

Fig. 5 1s a si e view of one of the spring clam s' p of the hinged Fig. 6 is a sectional view 7 1s 'a view showing my improved deperspective view 01 plan view of one of le and spring bolt;

' vice as a table; and

iii 8 and 9 are views of modifications of the 0 amp.

Referring to Figs. 1 to 3 inclusive, 1 is a drain board which may be of any sha e desired and of any material, having, in t e present instance, cleats 2, and in the underside of the board at the front edge is a rounded transverse groove 4. 5, 5 are sprin clamps spaced a given distance apart an each of these spring clamps conslsts of a leaf 7 rigidly secured, by'screws or other means, to the board and a leaf 8 pivotally connected to the leaf -7 by "a pin 9. The outer end of the leaf 8 is shaped as clearly shown in Figs. 4 and 5, so as to form a hook which is arranged to engage the rolled edge 10 of a sink 11, a portion of which is shown in Figs. 1 and 2.

ORA C. Cox, a citizen.


1n place, is rigidly attached the outer edge of .holdmg the w the sink.

' connected to the board by a Sinks are usuallymade with a rolled edge,

a .8 own, and the groove in the underslde Patented Dec. 17, 1918.

of the board is shaped to accommodate this I The hook is so proportioned that it will engage the lower edge of the roll, as

shown 1n igs. 1 and 2.

A'spring 12 is coiled around the pivot pin ring rests of the clamp and one end of the upon the fixed leaf 7 and the ot the spring rests upon the hooked that the tendenc the hooked lea spring is of'such hook is clamped to w ll 'l'lildly hold the board in position.

The card can be readily applied to the slallrl when in the position shown in Fig. 2 W1 ing under the rolled edge,

er endof leaf 8, so of the spring is to force toward the board. The strength that when the then, by raisin the board to its norma positlon, the springs will yield and the clamps will ress u on the edge of the sink, oard mly against the upper edge of the sink. An suitable leg or en port for the outer end of the board can he used and when the board is in the position illustrated in Fig. 1 ,it is rigidlyattached to I preferably use a single leg 13, which is hmge 15. The e is removable so that, pintle,the leg can be if desired, in packold the leg in its-extended position, I attach a spring bolt 17 to the leg. The belt is arra 18 in the table when the leg is in its extended position, as illustrated in Fig. 1. By withdrawing the bolt, the leg can be turned on its hm e and the outer end of the board lowere after which it can be pintle 16 of the on withdrawing the separated from the table, in or shippin 11 order. to

. readlly removed from the sink.

In Fig. 7, I have illustrated my device used as a table, and instead of being attached to the edge of the sink, a late 19 is used, which is secured to the wall or to the edge of the table. The clamps engage the extended portion of this plate.

some instances, a groove may be formed on the underside of a table top, so as toaccommodate the clamps, but I prefer the construction illustrated in Fig. 7.

In Fig. 8, I have illustrated a modification in which the clamp is made of spring the edge of the sink it the hooked end of the clamp extend nged to enter a hole v inetal and is so shaped that the hooked end of the clamp is directly above the groove in the end oi the board and a suficient distance from the board to enable the userto hook the board onto the ed e of a sink with the clamp 5 engaging the down turned edge or the sink so that when the board is raised the hook will automatically engage the rolled ed e of the sink and .will yield so as to place su%oient tension on the board to hold it firmly onto the rolled portion of the sink.

In Fig. 9, l have shown the clamp 53* made of spring wire, the two arms of the clamp being coiled to form the spring and the ends of the arms beyond the springs can be attached to the board by staples, or other fastenings.

It will be understood that the clamp may be made in many difi'erent ways, but in every instance the end of the hook must be located in such relation to the groove in the" under side of the board that it will be a sufficient distance from the base or the groove so as to allow the edge of the sink to enter the space between the base of the groove and the hook, as shown clearly in Fig. 2, so that when the board is moved to the position shown in Fig. 1 the hook will firmly engage the edge of the sink. and will force the grooved portion of the board firmly onto the upper surface of the rolled edge of the sink so that it will be seated firmly thereon and cannot move laterally. llhe leg is used as a means for holding the outer end of the board in the raised position and the hooked clamps between the groove and the board are depended upon to hold the board rigidly against lateral movement.

ll preferably make the leg tapered and comparatively small at its lower end, so that when the board is sold the leg is of such a length to support the board when the board is attached to an extremely high sink. if it rner eoc is to be applied to a low sink, then the leg is out ch? to accommodate the sink.

1 claim:

1. The combination of a detachable board; a transverse groove in the under side of the board and at one end thereof shaped to fit a support; a spring clamp at the same edge of the board as the groove, the clamp having a hook at its free end directl beneath the groove, the end of the hook eing spaced from the groove when in its normal position so as to allow for the insertion of the rolled edge of a support between the hook and the groove in the board, .when the board is at an angle below the horizontal, the hooked clamp yielding when the board is raised into position; and a hinged support for the outer end of the board.

2. The combination in a detachable board for sinks, of a board having a transverse groove on its under side near one edge, the groove-being rounded to fit the rolled edge of a sink; a spring clamp secured to the under side of the board consisting of a leaf rigidly secured to the board and a hooked leaf pivotally connected to the first men tioned leaf; 3. spring coiled around the pivot point of the clamp, one end of the spring bearing against the hooked leaf and tending to force it against the board, the hook being directly beneath the groove in the under side of the board, the end of the hook being spaced from the groove when in its normal position so as to allow it to engage the rolled edge of a sink when the board is applied at an angle to the sink so that on raising the board the grooved portion of the board will be drawn tightly onto the rolled edge of a sink; and a pivoted leg at the outer end of the board arranged to support said end independently.

ln witness whereof ll aix my signature.
