` 1o claims. (o1. 25359) This invention relates to portable rivet heaters which are easily carried from one place to another so that riveters may have the heated rivets conveniently at hand.
' Objects of the invention include the provision of a small but efcient portable rivet heater having a refactory brick lining, there being a rivet holder in the furnace for supporting rivets in a compact condition, and an oil burner which is mounted outside of the furnace but which is portable therewith; the provision of a portable rivet heater as aforesaid including a pivoted platform support for the oil burning unit, said support being mounted on the frame of the heater and being adapted for pivoting between the folded inoperative position and an extended operative position for further convenience in the portability and storage of the device; and the provision of a portable rivet heater as aforesaid including a flexible support for a free edge of the oil burner platform, and a weather protector therefor, said weather protector being supported on the flexible platform support.
Further objects of the invention include the provision of a portable rivet heater embodying a refactory bricklined furnace, a grate having bars which are spaced to permit the shanks of the rivets to depend therefrom, the heads of the rivets being supported on the bars, a separate oil burning. unit which is positioned to deliver a flame through a wall of the furnace at any desired point below the grate bars for uniformity in heat, there being a wedge shaped space take-up being positioned between one lateral side of the grate and the furnace wall so as to prevent loss of' heat, and there also being a pair of cover plates to be disposed on the rivet heads so as to maintain the heat under either of the cover plates while the other is removed to provide access to the rivets.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which Fig. 1 is a plan view of an embodiment vof my new rivet heater with the weather protector removed;
Fig. 2 is a view in side elevation of the rivet heater with parts in section and looking in the direction of arrow 2 in Fig. 1;
Fig. 3 is a section on line 3 3 of Fig. 2 with the weather protector omitted; Y
Fig. 4 is a partial plan view of the grate and showing the cover plates;
Fig. 5 is a view in side elevation of Fig. 4;
' Fig. 6 is an enlarged view of the grate take-up;
Fig. 7 is an enlarged view of `the'roil burner nozzle, parts being in section; and Y Fig. 8 is a bottom plan View of the weather protector.
As seen in Figs. 1 and 2, my new rivet heater comprises .a framework composed of a bottom member llL'longitudinal side members I 2 and end members lll. This framework is provided with aplurality of `legs I6 which as shown are in the form of angle irons which may be secured to the framework in anyfdesired manner. These legs extend below the bottom member I0 and spacethelatter from a floor line as at I8 in Fig. 2.
Thefbottom member l0 is overlaid by and sup@ ports Y,a bottom refactoryA brick lining 20, and the sides and ends of the framework are lined by similar bricks as at A22. A pair of handles 24 may be attached tothe framework ends orside members for carrying the entire furnace from point to Ipoint on the job.
In the present embodiment of the invention I disclose a grate which is composed of side members 26 and end members 28, there beinga plurality, inV this case Vthree for illustration, of grate bars 36 which extend longitudinally of the grate in spaced relation to the side members 26. The side members 26 and bars 30 are spaced to accommodate the rivet shanks or rivets being heated, the bars being spaced a distance just sufficient to keep or maintain the rivets by their heads as shown in 32. It will be seen that this grate .will accommodate a large number of rivets in a manner so that the rivet shanks depend below the grate. closed three legs 34 at each end of the grate and legs 36 on each grate bar and on the side elements 26, these legs being located at both sides of the center 38 of the grate as shown in Fig. l, leaving the center of the grate free and unimpeded to receive a flame through the center aperture 40 in a `side of the furnace below the grate. Thus it will be seen that the flame will enter the furnace below the grate, see Fig. 2, Iand not directly strike any of the metal of the grate.
I provide a pair ofV cover'elernents 42, each one of'which is adapted to cover one half of the ygrate area, and I provideV apertures lllV throughA these platessothat they may be removed and replaced bymeans of tongs. Plates 42 will over-lierthe In the illustration I have dis` removed while other rivets are still covered. I also provide a Wedge shaped space take-up 46 which is to be inserted as shown in Fig. 2 between the rear wall of the furnace and the adj acent grate element 26 so as to prevent loss of heat and escape of flame at the rear side of the grate while providing for easy removability of the grate in cases where a grate having bars of different spacing for different sized rivets is desired to be used in place of the grate shown. This space take-up member is provided with a handle 48.
A supporting platform 50 is pivoted as by a hinge 52 to a member of the framework, so thatv this platform may be extended as shown inFigs.`
1 and 2 at right angles to the heater for supporting an oil burner unit 54, or selectively .the platform may be pivoted into parallel relation with the adjacent side of the furnace for ease in portability and compact storage of theentire unit. I provide an aperture 58 in the platform 50ffor reception of a screw 'attached to the bottom of the oil burner unitV 54, there being a washer 8i! bridging the aperture and `used to hold the oil burner unit in correctly positioned location thereon for the best llame in the furnace.V
The oil burner itself comprises a Wick box B2' in which is mounted an oil pipe 64 leading from a source of oil not shown and extending forwardly to the left in Fig. 2 where it is coiled a plurality of times at 68 to provide a fire chamber. Oil pipe 54 is reversed at the forward end of the burner and as shown in Fig 2 a depending end pipe 68 -is provided to which is attached a nozzle l in a cap 'l2 which is screw threaded to the end of the pipe as shown in Fig. 7. The nozzle itself comprises an elongated element which is screw threaded into cap 12 'in the manner shown in Fig. '7,Y and this element is provided with a longitudinal passageway 14 forming the nozzle for the oil. Screw thread lion the element 'lll provides a dirt catching means for the oilflowinglthrough pipe 88.y The irregular surface provided by the screw threads inl reality forms a trap in which dirt particles in the flowing oil will be received.V
Apair of chains 18 'are suspended from hooks, 80 'and these chains pass into slots 82 in the 45dmeans.
platform U so that the free end of the platform 1s supported by the chains, slots 82 being narrower than the width of the links in the chain.
It is to be understood that the apertureM) through the brick wall of the furnace may be located in any desired position` other than that shown. For instance it might be located in either end of the furnace or in the side Walls Y Several of these aperlocated wherever the riveter is working; and
therefore the present invention will save time on any job;v and in Aaddition will ensure .a morev even and uniform heating of the rivets. A cover may be provided for the heater if desired and 1t will be clear that such cover can assume any desired form.

l. A rivet heater comprising a furnace, a grate l0 in said furnace including spaced bars and means to support the bars above. thev bottom of the furnace, oil burning means to heat the furnace, and a plurality of separate cover members for disposition over rivets supported on the bars,
