Be 1t known that l, VViLLIir loGnNs'oN, a.

'citizenfof the n United states, and, resident;-

ilus nventionf-rel tjes to chargingffo for enameli'ngjYfurnaces71 and itsprincip'alf object is to provide means for econom-izjng time in chargingenameling furnaces Withf articles-on n fhijch enamel is ,to bebaked. .ln` the 'ordinary practice, venamel jware is, loaded upon a :charging fork Whichwhenl loaded,` vis Y insertedV into 'the "furnace,` the material de,-r posited' thereinr V,andl the fork Withdrawn.V `When the articles have been leftinthefurnace for a sufficient time tobake the enamel thereon, the forkisretnactedand thelist,ar-y ticlesfremoyed from`I the furnaceQ Thereafter they are removedfroiiji. the forklfand afresh Z supply loadedthereon'and inserted as be-A 5 takes time, 'fuel is lWasted,l and `-While the baking process is going onythe fork is idle and time of the Workmen is Wasted.

f l have overcome the objectionable features by providing a double fork by means of which at least one fork is practically always in use, and the Workmenls time is continuously employed in loading or` unloading yone of the forks; the furnace also being continuously in use in baking the enamel upon the articles. `With these ends in View, this invention consists in a pair of chargingv forks,V

eachy operable lindependently of the` other,`

and both -rnounted "upon Wheels;A whereby o either may be brought intolichargng position f before a furnace door, While the other is disposed-at one side thereof, Vwhereby it mayL be loaded and unloadedwhile -the baking process is being carried on. The invention 15 further consists inV the severaljnovel features hereinafter fully setV forth and claimed. Y

The invention is clearly 'illustrated inv the accompanying drawings, in Which:

and illustrating one embodimentof the invention; Fig. 2 is a Vertical cross section taken on line 2 2 of Fig. 1, and Fig. 3 is .a plan of the charging fork, a fragment Of the enameling furnace being shown irihori- 5J Vof each set.

Other tie bars 16?L connectlie track-bars` i boltedor otherwise fastened together, toprovidea strong, rigid and substantial frame. They track bars 13, are approrrimatelyas. high as;y the piersal`7 and in the operation of the de il vice one set of tra-ck bars, is brought directly in front of the door opening a, and piers al, inV position to enable the associated ,fork to be inserted into theV furnace to deposit articles on the piers therein7 or to remove them therefrom. 9 Theforks may-be ofv .any suitable form and construction, and may be hand or power operated. The forks shown illustrateone form of manually operated forks; they are similar in construction and a description of manipulated.

the articles to be baked, and said work support may comprise spaced cross bars 22,

which are adapted to rest on the fork bars A16 of each fork, and upon the piers a1, when placed in the furnace.

on the railsY until `a loaded fork is brought directly in front of the furnace door opening; the door of the opening is then raised and the fork is moved forward into the furnace, and the work support, and articles carried thereby, are deposited on the piers in the furnace in the usual manner.`

The fork is then withdrawn from the furnace. rvVhile the baking process is being carried on, the other fork is being loaded with articles to be baked, and when thev articles in the furnace are finished, the furnace door is opened, the empty fork is inserted into the furnace, underneath the work support, the handle depressed, and the work support, and articles carried thereby, are

lifted from the piers, and the fork is withdrawn from the furnace. The carriage is thereupon moved over bringing the freshly loaded fork directly in front of the furnace y door opening and the fresh supply ofk articles is deposited in the furnace, as -above del y the furnace may be kept in continuous opera- Y In operation, the fork carriage is moved alon ftion, and there is no loss 'of time between and during the heats. l l

More or less variation of the exact details of construction is possible without departing'from the spirit of this invention; I desire, therefore, not` to limit myself .t'o the exact forni of the construction shown and described, but intend, in the following claims, to point out'allof the invention disclosed herein.

I claiml as new, `and desire to secure by Letters Patent:

y l. Charging means naces, comprising a traveling, wheeled carriage, two widely spaced sets of track bars securedv on .said carriage, land two fork frames 'mounted on rollers thatV travel on said track bars, each fork being movable independent of theother, and there beingfree and vunobstructed loading and unloading passages between ,said sets of ytrack bars, and between said lfork yframes, whereby either fork frame` may be loaded and unloaded fromv either side;

2. A Ycharging fork` for` enameling furnaces, comprising apair of sunken rails, a fork carriage having wheels traveling on said`rails,.two widely spaced sets of track bars securedon said carriage, and two charg- V ing forks mounted to travel 'on said track bars, there being free `and unobstructed loadingjand unloadingpassageways between said setsl of track bars, and between said charging forks, whereby either 'fork Ymay be loaded and unloaded fromk either side.
