ticles may be treated in a minimum length v of time.

Referringmore particularly to the draw ings, I have therein represented a table or support at .1, it being provided with supporting uprights 2 of any suitable character connected if desired bya cross piece or cross pieces- 3 herein shown as having a tray or receptacle 4 supported thereon.' The said table or support 1 is provided with a suit able opening 5 extending vertically therethrough and within which if desired, may

be positioned a bushing or wearing member 6 herein shown as having supported thereon a guide or wearing block 7 of annular'form and of any suitable material, such for ex-.

ample as hard fiber. Within said opening is adapted to be positioned .thejshrapnel shell or other object 8 to be coated interiorly and' if desired also exteriorl'y. The said,

shell atv its lower end is provided with threads 9 of usual. construction and adapted for the reception of the cap of the shell. It is desirable and important that the paint or other coating 10 be applied to the entire inner surface of the shell with the exception of the said threads 9 which are .therefore herein represented as protected by a suitable shield 11'11618111 shown as cylindrical in form and having ahead 12 adapted to be received upon-a ring-like support 13 upon which the lower end. of the shell is;positioned prior to commencing; the coating operation.

The ring-like support 13 is positioned at theupper end of a tubular member'14 hav- I ing an annular flange 15received upon and,

supported by a ring 16 itself'supported by 'one or more bolts 17 tapped therethrou'gh and adjustably connected therewith by means of a suitable nut or nuts 18. The said bolt or bolts 17 are tapped into and depend from a ring 19, the'construction being such that the primary ring or support-13 may be vertically adjusted with respect to the supporting ring 19. The latter ring has pinned thereto and depending. therefrom links 20, 21, which at their lower ends are pivotally connected to operating levers 22,

23 suitably spaced apart and respectively connected by

coil springs

24, 25 with the under side of the table or support 1 at 26, 27. Preferably said

levers

22, 23 are provided with stop screws 28, 29 which are positioned in longitudinal slots 30 in the under side of the table 1.

' the lower end of the tube 14,'being preferbrackets 31, 32 attached at 33, 34 to the under side of the table or support 1, as shown most clearly in Figs. 1 and 3'.

The construction and arrangement of parts as described are such that upon the insertion of the shell or other hollow arti ale 8 in the opening 5 the weight thereof or the weight and such pressure as may be imparted thereto by the operative depress the ring 13 and the supporting partsand. also rock the

levers

22, 23 upon their support. Preferably a guiding link 35 is provided, as shown most clearly in Figs. 1 and 3, to insure a right line movement of the supportingring 13 and associated movable parts. I have herein represented the link 35 as pivotally connected to the bracket 36 bolted to the under side of the table or support 1 and also pivotally connected at 37 to the said ring like member 11'. If desired and preferably two such guiding links 35 may be employed.

If desired and as here represented I may provide a forked guide 38 for the upper end of the shell, the same being herein represented as supported upon a pillar 39.

The paint or other liquid that is to be applied to the shell or other article is contained within a suitable tank 40, preferably having a loose fitting cover and supported by the discharge pipe 41 above'the level of the said shell 8. The said discharge pipe 41 is tapped in or otherwise secured to the table or support 1 and passes therethrough as represented most clearly in Figs. 1 and 3. Below the said table 1 the discharge plpe 45 has threaded thereto a fitting '42 into which may be tapped a pipe 43 through which the contents of the tank may, if desired, be drawn off. The said pipe 43 is herein represented as provided with a suit able valve 44. The said fitting '42 has also tapped therein a discharge pipe 45 having a valve 46 and'having threaded onto its lower end a valve casing 47.

Suitably mounted or supported upon the discharge pipe 45 or on any other desired part of the mechanism is a bracket 48 having connected thereto by a screw 49 a second bracket 50which, if desired, may have its upper portion connected to or bearing against The said bracket 50 has an arm 51 having an annular portion 52 supporting a waste or discharge pipe 53, the upper end of which surrounds ably spaced therefrom so as to permit the entrance of air at the upper end of said discharge pipe 53.

Tapped into the valve casing 47- is a paint discharge pipe 54, which passes through the upper portion of the discharge pipe 53 and the tube 14, it being provided at its upper end with a suitable spray-ingnozzle 55 of any suitable construction not herein necessary through the valve.

more fully to describe. The construction is, however, such as to permit the discharge of the paint in fine particles or globules over the entire inner surface'of the shell 8 or a transverse passage 57 therethrough and is here shown as having a threaded extenson or spindle 58 receiving thereon a nut 59 between which and a washer 60 is positioned a coil spring 61 acting to hold the valve in position and co-acting also to afford a tight joint. In conjunction with said valve I provide a surrounding packing 62 herein shown as having a passage 63 therethrough which may coincide with the passage 57 In order accurately to measure the charge contained within the valve and also to vary the amount of said charge, I have herein represented the valve as recessed at 64 and having tapped therein a threaded bolt 65, the inner end 66 of which may be positioned at such point as is necessary to permit the introduction of exactly the proper charge into the passage 57 of the valve. 7

I have herein provided means for forcibly discharging the charge or measured amount of the paint or other liquid from the passage 57 of the valve, though within the broad scope and purpose of my invention, the charge might be permitted. to flow by gravity with the partssuitably arranged to such end. Preferably, however, I employ compressed air or other fluid under pressure.

For the purpose, I have herein represented an air supply pipe 68' leading from any suitable source and supported upon the discharge pipe 47 by meansof a suitable bracket 69. The said pipe 68 is herein represented as bentand supported by the bracket 48 upon the pipe 45. At a suitable point said. pipe 68 is provided with asuitable fitting 70 tapped thereonto and having a threaded connection 71 with the lower end ofthe valve casing 47 as indicated in Figs. 3 and 6, whereby when the valve 56 is turned into the position shown in Fig. 5' and the valve governing the air supply is open, the charge of paint or other coating material is ejected through the nozzle 55 and sprayed against the entire inner surface of the shell or other article 8. p

The fitting 70 is provided with a pet cook 72 and at a suitable point the air supply pipe 68 is provided with a valve casing 73 shown in section in Fig. 8, and having therein an axially movable valve 74 provided with a valve disk 75 and normally held in closed position by a coil spring 76 which is assisted by the pressureof the air. The

stem of the valve 74 extends through the casing 73 and is adapted to be engaged and intension of thevalve casing and having at its opposite end a pin or screw 80 positionedwithin alongitudinal slot 81. in a link 82,

the opposite end whereof is pivotally con-' nected at 83 to the arm 84 of one of the

levers

22, 23; The said levers 22,-23 are fixedly connected as shown in Fig. 5 to the valve 56 and moved to the right viewing Fig. 7 ,.so that the figure, engages the screw'80 upon the lever 78 and thus opens the air valve 74. Thereupon the charge or measured quantity .of

paint is discharged from the valve 56 and sprayed into the interior of the shell 8.

The valve 56 is returned to its closed position by the

coil spring

24, 25, and the air air pressure. 25

valve 74 is closed 'by the spring 76 and the The surplus paint, if any there be, and the air used in discharging the paint from the valve, is discharged through the depending pipe 53, and in such discharge of air or air and paint, air may be entrained between the upper end of the pipe 53 and the tube 14.

In that form of my invention shown in Figs. 1 to 8 inclusive, the charge or measuring valve is opened oractuated bythe positioning of the shell or other article 8. While I prefer so to operate the alve, this is not essential to the broad scope and purpose of my invention, and in Figs. 9 and 10, I

have represented another form of my inven- L tion wherein the said valve may be operated manually or by 'treadle means. Referring to said Figs. 9 and 10, the parts therein.

shown excepting as hereinafter described, are similar in construction and mode of operation to those shown in Figs. 1 to 8 inclusive. In said Figs. 9 and 10, I have provided an annular support 85 to. receive the threaded end of the shrapnel shell, the threads thereof being protected by the outer surface of said support 85.. If desired, the outer surface of the shell may be coated and to this end I supportat any suitable point a stationary nozzle not herein shown and which may have discharged therethrough in any suitable and preferablyautomatic manner similar to that by which the valve 56 is operated, a proper quantity of paint or other the construction and arrangement of parts are such that upon depression of said

levers

22, 23, the valve 56 is rotated into the posi-v tion shown in Fig. 5, and the link 82 isleft hand end of the slot '81 viewing said the nozzle 55 preferably of similar construction to'that shown in Figs. 3 and 4..

' The construction shown in Figs. 9.and 10 differs from that-shown in Figs; 1 to .8 parally or by treadle, and to that end I have 1 tially in that the valve 56 is operated manusubstituted for. the

levers

22, 23, a lever 88 having a handle 89 by which it may be rotated upon its pivotal support. If desired,

form, and the arm 90 thereof is connected the said lever 88 may be connected to a 15 by link 91 to an, air valve of construction 80 similarito that shown in Figs. 7 and 8 and which need not be further described.

The support 85.. for the threadedend of the shellis carried by a ring v92 itself-mounted for'rotation upon a suitable bearing 93, and also having attached thereto by screws 94 and depending therefrom a suitable tube 95 surrounding the paint discharge pipe 54 and having fast thereon a driving disk 96.

Attached to the under side of the table 97 is a yoke-like bracket 98 having mounted therein for rotation a shaft 99 which -has fast thereon a pulley 100 preferably driven continuously from a' small motor of any suitable type. As-indicated in Figs. 9. and 10, the bearing 101 for said shaft 99 is supported by

pivotal bolts

102, 102, whereby said shaft 99 may be slightly rocked in a, vertical plane. Adjustably mounted upon saidshaft 99 is a non-toothed driving pinion 103 which may be adjusted to any position along said shaft 99, thereby to engage with the-disk 96. at any desired point from the I center thereof. In this manner, I'permit the rotation of the disk 96 and hence of the shell at any desired speed, so that the paint or other liquid may be applied to the inner and if desired to the outer surface thereof in said shaft 108 is preferably'mounted in the lowerv portion of the bracket 98 as shown most clearly in Fig. 10. The shaft 99 has an inner bearing 110 which is supported by a pin or spindle 111 resting loosely upon the.

cam shaft 108. When said'latter shaft is turned into the position shown in Fig. 10,

the bearingllO of the'shaft 99 is permitted I to drop slightly, thus withdrawing the driving pinion' 103 from driving'en'gagement with the disk 96.
