Application lllediEebruai-y 18, 1927. Serial No. 169,319.
a light, beam on the object being treated,
whereby to enable the operator to clearly observe the surface being treated, especially in dark-places wherein the room artificial lighting system is insuflicientto render such surfaces clearly visible for efficient coating.
What I aim to do, is to provide an excep-,
tionally' simple and inexpensive electric lamp enclosed in a housing which is especial- .y constructed to permit it to be attached to a. conventional form of. paint spray gun without requiring alterations of the stock Darts of the gun.
The lamp attachment is characterized by exceptional simplicity, ,inexpensiveness of manufacture, efficiency in construction, case n attachment and. removal, and durability.
An important factor to be considered in he construction of the novelty is. the arangementof the light or lamp casing along- :ide of the paint conducting barrel of thegun in order to take advantage of the-heat 'adiating' from the light for heating the mint as it passes through the 'barrel to cause t to flow freely. i
Other features and advantages of the in- 'ention' will become apparent 'from the folowing description and drawings. r
In the accompanying drawings forming a art of this application, and in -which like .umerals are employed to designate like arts throughout the same Figure 1 is a side elevation of the convenional gun showing the lamp attached to one ide of the barrel thereof. v Fig. 2 is a rear end elevation-of the same. Fig. 3 is a top plan view. Fig; 4 is an enlarged longitudinal section irough the attachment per se. Fig. 5 is'a cross section on the line 55 of ig. 4, looking from left to right.
Fig. 6 is a fragmentary perspectiveview iowin the light casing and" lens retaining im, with the 'pin and bayonet slot connecon.
The gun represented in the drawings,is
5 conventional construction, being of the r A De'vilbissconstruction. It ncludes mile 1, paint barrel 2, air. hose connecconsidering this figure,
tion 3, 'fluid hose connection 4, universal air cap and nozzle head 5, together with fluid needle adjusting screw 6 and handle retaining'nut 7. Incidentally, the handle inthis case is provided with a sleeve at its top which fits over the adjacent end of the barrel and is held in place by the nut 7. i
I mention this because the attachment, which is generally designated by the reference character- 8, is closely associated with these details. The attachment as is better shown in Fig. 4, comprises a cylinder 9, a light bulb 10 located therein, a socket 11, a switch chain 12, and support and connecting member 13. The latter is provided with'a circular base 14 which is riveted to the closed end of the cylirider.- The oppositeend of the cylinder is provided f with an inturned flange, and the lens 15 is held against this by a removable retaining rim 16.
with a bayonet slot 17 as shown in Fig. 6 and the lens retaining rim is. provided with a pm 18 which fits into this slot and holds the ens in place. The electricity conductor is represented 'by 'the. reference character 19. ln this connection, it will be noticed that a suitable retaining member 20 is providedat this end of the cylinder and serves to hold an attaching disk 21 in place. This disk is provided with an arm 22 terminating in a connecting ring 23. As shown better m Fig. 3, this connecting ring- 23 is arranged between the'sleeve 24 on the'upper end of the handle 1, -and the retaining hat 7. I
These details are existing ones on the ordinary gun and I take advantage of-this because the attachment therefore requires no. alterations of the stock parts. While it will be noticed that the length of the device is slightly less than the length of the adjacent portion of the gun, and that the lens terminates in inwardlys aced relation to the spray head, or nozzle.- oreover, the'lamp cylinder is in metallic contactwith the gun barrel and as Incidentally, the cylinder is provided before stated, it is important to note ,ihatthat the light has the additional function of heating the paint as it passes through "the barrel, thuscausin it to flow freely. This is a pointiofnovefiy to be emphasized.
It is plain to be seen that withthis construction theoperator can. coat the surface treated in a'moreelficient manner due to the factthat' the beam of light from the lamp will be projected onto'the surface and will render it clearly visible under all conditions.
It is believed that the construction, and use, and advantages of the invention will be clear to persons familiar with guns of this character. Therefore, a more lengthy description is thought unnecessary.
While the preferred embodiment of the invention has been shown and described,'it is to be understood that minor changes coming within-the field of invention claimed ma be resorted to if desired.
Ilaving thus described my invention, what I claim as new is As a'new roduct of manufacture, a lamp attachment or Saint spray guns comprising a cylinder close at one end andhaving an inturned flange at its opposite open end, a
- by said lamp socket in the cylinder, a lamp carried socket, a connecting stem carrie by the socket and including a circular base fastened to the closed end of the cylinder, switch operating means carried by the lamp socket, a source of current supp] associated with said socket, a lens ring against said inturned flange, a retaining rim for the lens detachably connected wit the cylinder, a disk bearing against the outer surface of the closed end of the cylinder and havin a central opening, having an arm exten ing from one side, and an attaching ring carried by the outer end of the am.
In testimony whereof I aflix my signature.
