Specification of Lettere Patent.

' vintegree aprii i7, ieee- Applicatilm filed August 18, 1905. Serial No. 274, 803.

To VajZZ whom it may concern:

Be it known that I, LIBERTY WALKUP, a'

citizen of the United States of America, reei'ng at Rockford, 1n the county of Winnebago and State oflllinoisfhave invented certain ynew and useful' Im rovements in Air- Brushes, of which the fo owing is' a specification-' -Myinvention relates to that class of instruments whereby artists are enabled toreduce.-

india-ink and other pigmentawhen in a more or less iiuid condition, to the Aform of spray during the act ofapplying the same to produce pictorial effects; an constructions and combinations of parte forming an airbrush hereinafter described and sfpeciiically pointed out in the claims hereo. Referring to the accompanying drawings, which form a ure'l is a side view of' an igment-rece tacle thereof verticallysectione .v Fig.2is a. Ongitudinal central vertical sectionV of the same minus the pi ment-receptacle. Figl Sie aseotion, at'the' otted line "3 3 inFig. 2. of parts there shown. Fig. 4 is a section, at thel dotted line 4 4 in Fig. 1, of parts there shown.-

Fig. 5 is an isometi'ical detail of a clamp detached from the instrument.

Like letters of reference indicate correspending parts throughout the several views.

threaded to ada -removed from t is a pigment reoeptacle, referably of glass and providedwith a cover X', preferably of metal and having its connecting-flange A2 t it to be turned u on and e correspondingly-t eaded neck A3 thereof.

B is a tubular body threaded exteriorly at B throughout a portion of its length and provided with an inwardly-sloping perforated shoulder portion B2, terminating in a neck B3.

C is a conical plug having a tapering central bore C', extending longitudinally therethrough and tapped at its base C2 into the; free end of the neck B3 of the body B.

D is a conical cap provided with an annular groove DE inthe exterior thereof and having the interior of its larger end portionD fitted closely to but slidable upon the unthreaded ortion D? ofthe body B and the interior otpits smaller. 'end portion Da tapered to conform to but not Contact the exterior of it consists of the .the latter part of this specification, Fig-v shoulder B2 of-the `body to the point a of the instrument.

' E is a circular'nut having an 'annule-1 groove E in the exterior thereofandthreadedI interioriyto adapt it to be turned u on the.oorrepondingly-threaded portion B of A.

the body lF is'acla'mp seated in the oove E in the nut E, and projecting arms gl into loose engagement with the groove D in the cap D, so as to regulat'ethe endwise movement of tate. e aan afi-tube egim med at one me G into the lar e end of the body B and connectand by means ofa rubberitube Gs with an air- H is an air-tube-opening into and extending transversely from the air-tube G through he cover A into the interior of the pigmentreceptacle A.

I is a pigment-tube tapped -by one end l thereof into the inner end portioiiof the neck B3 of the body B so as to leave a pigmentchamber I2 in the central portion of such. neck B3 and extending therefrom along the' interior of the air-tube G for the greater part of its length and thence transversely thereoutthrough its side at I" with another tube I3, extending'through the cover A into the pigment-receptacle A.

I4 isa downward extension of the tube la and is provided at its lower end with a pigment-strainer I5.

while leaving the nut E free to 'rointo connection J is a valve mounted in the tube Hand provided with oppositely-extending integral.- pintles J J2. Y

J3 is a valve mounted in the tube I3 and plrotrzided with an outwardly-extending pint e 4.

J4 and intermesliing. 2 is a finger-leveifast to the pintle J on the valve J.

L pigment-receptacle A..v

is an arm fast to the lever K2 extending therefrom'through and lengthwise of the spring-case' L.

is a spring-case fast to the cover A of theA K K are segment-gears mounted fast on the intles J2 IOO L2 is a spring included in the case L and coiledahoutthe arm L and acting through the latter and the lever K2 to close the valves J JS, as in Fig. 3. if the lever liz be deressed toits lower limit, the valves d' .la will e thereby opened, as in Fig. 2.

M is evolve for closing the air-tube G.

Air under pressure being sup lied to the instrument through the tube G3, its operation to is as follow; Liquid p'fonent is thereby forced through the parts 5, it, la, and l into the reservoir l2 in the neck B of the body B, whence it passes under pressure throuvh the bore D in the plug C to its point. t the seme tiineI air under 'pressure is passing through the parts G B and from the latter through the erforations D5 in the shoulder portion B2 o, the bodyzB into the annular air-chamber Dt, whence it passes under pressure to the point of the cap D and atoniizes the li uidpi ment at the point of the nlug T e farter the point of the cap is projected beyond the a ex. of the plug C by the nut E the more nely Will the liquid o5 pigment loc atoniized, since it Will be acted upon by a larger volume ot compressed an' when the interior ot the' cap D is in closer proximity to the plug C.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent, is
