DRYING-OVEN.

Speccaton'of Letters Patent.

Patented Nov. 24, 1908.

Applicationmed Anglia 1o, 1906. serial No. 329,988.

citizen of the United States, residing at` the city of Philadelphia, in the county of Phi ladelphia and State of Pennsylvania, have 1nvented a certain new and useful Drying- Oven, of which the following is a specification.

One object of the present invention is to provide an eiicient and convenient oven for baking a finish on tools and the like.

Another object of the invention is to provide an oven and its accessories by means of which a great number of tools can be treated in a comparatively short time and even by unskilled labor. y Y

T o these and other ends hereinafter set forth the invention, statedin general terms, comprises the improvements to be presently described and I'inally claimed.`

The nature, characteristic features and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a perspective view illustrating y an oven embodying features of the invention and showing some of the parts removed. Fig. 2, is a similar view illustrating parts of the apparatus shown in Fig. 1. Fig. 3, is a sectional view illustrating a detail of con-` struction. Fig. 4, is a view illustrating another detail of construction, and Fig. 5, is a view illustrating one of the end frames of the oven. f

In the drawings l and 2, are a pair of ovens arranged side by side and each is open at both ends and the open ends are tted with doors 3. There is a lengthwise ranging slot or opening 4, through the top wall of each oven, and each oven ris tted with a heater 5, shown as consisting of a gas burner arranged lengthwise along the floor of the oven.

6, indicates valved gas fittings for supply-u ing the heaters or burners 5.

Arranged above the oven and parallel with the slots 4, are tracks 7 and 8, which extend beyond the ends of the oven. 9, are carriages adaptedto these tracks and suspended from them are carriers 10, 10a, 11 and 11a. Each carrier consists of a plate having at its top rods 12, which are connected with the respective carriers by turn buckles so that the carriers may be turned around while they are `suspended from the carriages.

13, are pins which projectfrom the faces of the plates that constitute the carriers. As shown these pins project through the carriers and areprovided on one side with a head 14, and on the other side with a nut 15.

16, are coverV plates adapted to be detachably laid over the slots 4, and they are marginally notched for the accommodation of the rods 12. The oven consists of two end .frames connected together by metal inside and outside sheets which constitute the top, bottom and side walls of the ovens, and each frame consists of two generally rectangular frames 17, slotted as at 18, and secured together along their meeting edges as at 19. The space between the inner and outer sheets is lled with asbestos between the frames 17.

20, are shields arranged above the burners 5.

In use one of thecarriers is placed in each of the two ovens and the other two carriers are outside of the ovens. Upon the pins of the carriers which are in the ovens are suspended tools, the finish upon which is being baked and tools which are to be baked are being hung upon the pins of one of the other carriers and finished tools are being taken off of the other carrier. For this purpose the carriers may be turned about their swivels so that the operator may have access to the pins on each of their faces. The operator may rst put upon the proper carrier the tools which are to be baked and then remove those which have been baked from the other carrier, and this may be done while two of the carriers arein the oven so as to have the tools which `they carry baked. When the carriersare to be moved, the plates 16, are removed and these plates are applied so as to confine the heat during the baking operation just as the doors 3, are closed during the baking operation andare opened to permit of the movement of the carriers. In this way the operator may hang tools upon one of the carriers, remove tools from the other of the carriers while tools are baking at different stages of completion on the other two carriers and by repeating these operations with the `various carriers in rotation practically' none of the attendants time is ost.

I claim:

1. drying apparatus consisting of two ovens arranged side by side and respectively The combination o't` an oven provided at provided at their' tops with slots and at their l its ends with doors and at. its top with a slot,

ends with doors7 carriers provided with facial pins, and arranged to enter and pass through the oven space, tracks having movable carriages and arranged above the slots, connections between the carriages and the slots, and heating means within the ovens, substantially as described.

Q. rPhe combination of an oven containing heat-ing means and provided at its ends with doors and at its top with a slot, a track having a movable carriage and alined Wit-h the slot, a tool carrier adapted to be received by the oven, suspension devices interposed between the carrier and the carriage, and a cover plate adapted to close the slot and notched for the accommodation of the suspension means, substantially as described.

a heater arranged near the Hoor ot the oven iii aliiieinent with the slot, a shield over the heater, a tool. carrier, a track having a movable carriage and alined with the slot, and

l means for suspending the tool carrier from carriers which are accommodated by the` the carriage, substantially as described. 4E.
