r The invention relates to apparatus forcoating furniture or in fact any otherport'able articles or objects with paint, varnish or other finish.

It. is well known thatit is aYCOVmIIIOQn Prim; I

tice, in modern times to finish many sorts of articlesby spraying them with paint, lacquer or other liquid coating compositions. Naturally the vehicle forthe pigment or other b' -material is volatile and if breathed in large quantities by the workmen isiinjurious to health. As a consequence it is customary to provide some sort of. cabinet or booth in which the spraying operation is carried on, T5 'means being provided such as a suction fan'or other ventilating device, for Carrying off the V fumes and vapors given-off. VHowever, this is only one of'the problems encountered "in this sort of work and there is ,anotherof great.

ffimportance, namely waste of coating material. The spraying is done by some sort of atomizer device necessarily with air pressure and the sprayed material which does not im-' pinge' against the article or object being treat-- tied is lost. It is a common occurrence for sev-' eral gallons of the coating material to goto waste in this way in a single days work.

It is with the above last mentioned fact in view that wehave devised the present inven tion which has for its object the provision of a novel work holder for supporting the ar'ticles or objects to be coated; this holder being of such construction asto salvagethe spray material which would otherwise bewasted."

5- a An important object of the invention is to provide a work holderof this type which is 1 rotatably mounted so that the operator may easilygain accessto allsurfaces of the article or ob] ects thereon so that the same maybe ef:

A further object of the invention is to provide a self-contained device of this character: in which the surplus coating material which would otherwise be wasted may accumulate" expensive to make, easyto assembleandusey in the base 10. An ordinary rotatable stand a may be: fastened onto the table in any desired that an'y-foreignmatter will be'efi'ectually removed and preventedgfrom impairing :the

quality and-fitness of the "salv-agedfliquid.

An additionalobject isto provideadevice of this character which will be simple and in- 5 positive in action, efhcientanddurable inf service; and ageneral inrprovement'in the art; I

T0 the attainmentof' the foregoin g'and", other objects and advantages, the inventibn' preferably consists in the details'ofconstru'ction and the arrangement and combination of parts to be hereinafter more fully described, and claimed, and illustrated in the laccompanying drawingsi'nwhichx- Figure 1 is a 'sideelevat'ion of" our work holding device with parts broken away and a in section to disclose the construction-more clearly and I V Figure 2 is a fragmentary top plan view with a portion ofthe wirescreen broken Referring more particularly to the d-raw'-' ings, the numeral 10 designates a suitable eta tionary base which may be mountedin-any desired manner upon the ground, floor or T other foundation. This basecarries the Work holder whichcis here represented as comprising a Platform or table 11 of either solid or skeleton construction, thisidetail being rather immaterial: However, this tableis disclosed as having a depending peripheral flange "12' for stiffening purposes an'dif desired may} also be provided with an'y suitable"numberof radial or other. bracing arms J13. The mountingimay simply comprisea hub 'mem ber 14 secured on the undersidefof the table and carryingfla stub shaft or trunnionlt re k movably engaged within aso'cke'tor bore- 16 such as that described up to this point isn ot "novel in itself. a

In carrying out the invention we provide an upstandingguard flange or shell member 17 preferably constructed of sheet linejtali mounted upon the top of the table If, it'bei'n'g a convenient plan 'to"forrn.thelower end of this shell witha'n' outstanding flange 18 which mannen iLocated withinitlie confines of the so I i shell 17 is an inverted conical hopper or basin 19 which is likewise preferably constructed of sheet metal and which may be removably held within the shell by the simple expedient of providing it with an outstanding flange 20 at its i upper edge overlying the I upper edge of the shell, this basin member being telescoped 'within theshell. The lowest point of the basin is substantially at its center, at which point there is mounted a discharge pipe 21 equipped with any suitable cut-off valve or cock 22. v i I To provide a horizontal surface for supporting objects or articles to be worked on, for instance a table as indicated at A in the drawings, and also to prevent foreign matter 7 from entering the basin member, we provide a wire screen 23 covering the open top of the basin. While 1t is conceivable that this screen might be held in place in any one of'several differentways, it is a convenient plan to provide it witha downturned peripheraledge f or flange 24 telescoped within the basin mem- 7 one of the conventional cabinets, hoods or 1 booths but such is not shown as it constitutes no part of the present invention. The paint,

varnish or other material is then sprayed onto the article in the customary manner. The

point is that the excess material, or that which does not impinge against the article being coated, will pass onto and through the wire screen and collect upon and withinthe basin member 19 where it will accumulate until the valve or cock 22 is opened to permit its discharge into some suitable receptacle.

In order to avoid clogging of the screen,it is preferable that at the end of each days operations it be wiped off with some solvent appropriate for use in connection with the particular coating materialbeing sprayed. In case the necessity should arise the screen can be removed to permit cleaning of the basin member and the basinmember may be detached from the outer or enclosing shell. In actual practice we have discovered that by means of this device it is a common matter to save four or five gallons of high priced varnishwhich would otherwise have gone to Waste. This salvaging work holder will consequently reduce the-cost of finishing furniture and the like and is-boundto be of'great value in factories and other places where this work is carried; out on an extensive scale.

HWhile we have shown and described the preferred embodiment of the invention, it

4. A liquid salvaging work holder com should be understood that the disclosure is merely an exemplification of the principles involved as the right is reserved to make all such changes in'the details of construction as will widen the field of utility and increase the adaptability of the device providedsuch changes constitute no departure from the i V spirit of the invention'or the scope of the claims hereunto appended.

' I Havingthus described the invention, we

claim: r

'1. A work holder of the character 'described comprising a stationary support, a rotatable table thereon, a. basin member carried by the table and having drain-ofii means,

and a foraminous top forthe table.

2. A liquid salvaging work holder comprising a rotatably mountedtable, a shell member mounted thereon, a collecting basin within said shell member equipped with drain-off means, and supporting means ex tending overthe top of the shell member.

3. A liquid salvaging work holder comprising a. table, a shell mounted thereon, a basin telescopically engaged within the shell and supported thereby, drain-off means for the basin, and a perforated cover for the shell prising a table, a shell mounted thereon, a

basin telescopically engaged within the shell and supported thereby, drain-off means for y the basin, a screen for the top of the basin having a downturned edge telescopedthereinto, and'a securing band located inwardly of said downturn'ed edge for holdingthe same in contact with the wall of the basin.

r 5. A liquid salvaging work holder comprising. a stationary support, a rotatable table carried thereby, a shell mounted on the table, a basin telescoped within the shell and having an outstanding flange overlying the upper edge thereof to be supported thereby. drain-off means for the basin, and a perforated support extending across the top of the basin and constituting the top of the'shell.

6. VA device for supporting an object while the same is beingtreated with a liquid comprising a stationary support formed with. a bearing, 'a'table having a depending central spindle pivotally engaged within said bearmg, an upstanding shell member mounted on the table and rotatable therewith, :a basin member located within and extending entirely to the periphery of the shell member and equipped with drain-off means, and a skeleton support mounted at the top ofv theshell member and extending entirely thereis across.
