Feb. 3, 1931. w. w. M CARROLL IMPLEMENT HEATER FOR ELECTROTYPE BUILDERS Filed April 2'7, 1929 Patented Feb. 3, 193 1 FFICE IMPLEMENT HEATER FOR ELEGTEOTYPE BUILDERS Application filed April 27,
This invention relates to an improvement in heaters and particularly to heaters for heating the implements or tools employed l I electrotype ma rers in building up and altering the wax forms from which electrotypes are made.
The object of this invention is to provide a simple and convenient heater of the c -4 described constructed with particular lQs.c-Z
ence to supporting the implements in convenient position for use and to providing ready drainage for the wax, which may be adhered to the implements when they are replaced in the heater.
With the above and other objects in View, my invention consists in a heater having certain details of construction and coin inations of parts as will be hereinafter described and particularly recited in the cla is.
In the accompanying drawings:
Fig. 1 is atop or plan v ew of a heater constructed in accordance with my invention, the implements or tools which it is designed to heat being shown by broken lines;
2 is a view thereoi in side elevation;
Fig. 3 is a longitudinal sectional View taken on the line 38 of Fig. 1;
4 is a transverse sectional View taken on the line l% of Fig. 2; and
Fig. 5 is a transverse sectional view corresponding to Fig. 4 but showing a modified form of heater adapted for steam.
In carrying out my invention as herein shown in Figs. 1 to 41 inclusive, I employ a 35 box-shaped body-member comprising a topplate 10, integral front and rear end-walls 11 and 12 and integral side-walls 13 and 1 1. The front and rear endwalls 11 and 12 being extended downward to form respectively plate-like supporting- legs 15 and 16 each of which terminates in an outturned horizontal flange 17 through which screws may be passed for securing the device to a work-bench.
Depending within the casing of the heater from the top-plate 10 thereof, are aseries of cone-shaped skirts 18 which produce a series of conical sockets 19 having their larger diameter intersecting the upper surface of the 59 top-plate 10 and having their lower ends 1929. Serial No. 358,472..
opening through the underface 20 of the conical skirts 18.
Each of the sockets 19 above referred to is adapted to receive and support the conical head 21 of an electrotype builders tool (shown by broken lines in Figs. 1 and 4:) which may be of any approved form and is provided at its upper end with right-angled shanks 22 terminating in handles 23 of wood or other heat-insulating material.
Extending longitudinally through the easing is a gas-burner tube 2 1 which is externally threaded at its rear end as at 25 for threaded engageme 5 with the rear end-wall 12 of the said casing The front end of the tube 24 extends through the front end-wall 11 of the casing and is there provided with the usual mixingchamber 26 having the usual knurled mixture adjusting-ring 27 and carries a gascock 28 which controls the flow of gas into the burner-tube 24.
The burner-tube 2 1 is as shown located to one side of the series of conical skirts 18 depending trom the top-plate 10 and is formed with a series of ports 29 directed toward the said skirts 18 and slightly upward so as to project the flame substantially crosswise of the casing and in the general direction of the series of conical skirts 18 before referred to.
The portion of the upper face of the topplate 10 lying between the first of the series of sockets 19 and the front end of the casing is slightly depressed as at 30 and is intersected by-a series of vertical passages 31. The space 30 upon the top-plate 10 is designed to receive such knives and other implements which are not suitable in form for being supported in the sockets 19. The passages 31 affording an upward egress from within the casing for the products of combustion which serve to heat any implements that may be placed on the surface 30.
The rear end-wall 12 ot the casing has secured to it by means of screws 32 a substantially L-shaped bracket 33 upon which implements may be stored when not required for immediate use.
The front end-wall 12 and the sidewall 11 of the casing are each provided with a series of vent-openings 34 designed to permit the lateral egress of the products of combustion and thus insure a substantially uniform temperature within the chambered interior of the said casing.
By locating the burner-tube 24 to one side of the series of tool-receiving sockets 19 the adhering wax melted from the heads 21 of the tools after they have been in service and restored to the sockets for further heating, will drain out of the open bottom end of the said sockets without coming in contact with the said burner-tube EZ-it so that obnoxious smoke and the clogging of the gas-ports 29 in the said tube are avoided.
While I have shown and described herein a heating-element designed for using gas, it will be readily understood that the same may be replaced by an electrical or other heatingelement.
In Fig. 5 I have shown an implement heater which generally corresponds to the structure shown in the preceding figures except that it is adapted to be heated by steam. For this latter purpose I provide a bottomplate 35 extending laterally between and formed integral with the front. rear and side walls 11, 12, 13 and 14-, and also integrally connected to the lower ends of the skirts 18.
The provision of the bottom-plate 35 as just above described, serves to form an onclosed steam-chamber 36 into whicl steam may be introduced from a supply-pipe 3'? having a coupling 38, the threaded nipple 39 of which is threaded into and projects through the side-wall 13 into the steamchamber 36.
I claim:

As a new article of manufacture, a heater for independentlyformed tools comprising a horizontal plate having one or more tool-receiving sockets intersecting its upper face and depending beneath the upper sur face of the said plate and open at their lower ends; means for supporting the said plate; and a heater element located to one side of the sockets in position to radiate heat laterally against the same.
2. As a new article of manufacture, a heater for independently-formed tools comprising a horizontal plate having one or more socket-skirts depending from its underface, the said skirts having formed therein sockets opening through the upper face of the said plate and also opening through the lower end of the said skirt; means for supporting the said plate in spaced relation above a support ing-surface; and a heatenelement located to one side of the said skirts and adapted to 'adiate heat laterally toward the same.
