BLACKING-BOX FOB. JAREING-MACHINES.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed June as, 1910. Serial No. 568,736.

T 0 all whom it may concern:

jarring machines.

The object of the present invention is to provide a simple, strong and comparatively inexpensive blacking box, designed for use on jarring machines, and adapted to enable the sand molds to be blacked without removing them from the jarring machine, and capable of catching the superfluous blacking mixture as the same runs from the lower end of the flasks and of discharging the mixture into a bucket or other receptacle placed at one side of the machine, and adapted also to permit a torch to be introduced into it to illuminate the interior of the mold, so that the latter may be inspected from the top.

A further object of the invention is to provide a blacking box of this character, adapted to be readily applied to a jarring machine, and capable of sustaining the weight of a multiple flask, and equipped with means for centering the flasks as they are placed on it by a crane, or other means.

Another object of the invention is to equip the blacking box with a removable top, adapted to facilitate its construction and afford accommodation for all types and sizes of pipe flasks.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation of a blacking box, constructed in accordance with this invention and shown applied to a jarring machine and supporting a multiple flask, a bucket being in position for catching the blacking mixture. Fig. 2 is an.

enlarged plan view of the blacking box. Fig. 3 is a central longitudinal sectional view of the same. Fig. 4 is a plan view ofthe blacking box, the cover being removed. Fig. 5 is a reverse plan View of the removable cover. Fig. 6 is a detail sectional "iew on the line 66 of Fig. 2. F 7 is a reverse plan view of one of the centering plates.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the embodiment of the invention illustrated in the accompanying drawings, 1 designates a blacking box, constructed of suitable metal and designed to be mounted upon I the table 2. of the piston 3 of a jarring machine, and capableof supporting a multiple flask 4, as illustrated in Fig. 1 of the drawings. The jarring machine shown in Fig. 1 is not claimed in the present case, as it forms the subject-matter tion, executed by me of even date herewith the serial number of which is 568,735, and while I have shown the blacking box applied to my improved jarring machine, yet it will be readily understood that it is applicable to various jarring machines and may be readily applied to the same by securing it to the tables thereof.

The blacking box, which is substantially oblong, is composed of an inclined bottom 5, integral side walls 6, and front and

rear end walls

7 and 8. The bottom 5 is inclined toward the front end of the blacking box, and is adapted to direct the blacking mixture to an approximately Lshaped discharge spout 9, having an attaching flange 9 bolted, or otherwise secured to the front of the blacking box at a discharge opening 10 and having a depending portion adapted to deliver the mixture into a bucket 11, or other suitable receptacle. The bucket 11 is designed to be arranged upon a suitable support 12, located at one side of the machine beneath the spout, as clearly illustrated in Fig. 1 of the drawings. The blacking box is provided at the bottom with an outwardly extending horizontal attaching flange 13, presenting a flat lower face to the table of the jarring machine and adapted to be secured to the same by bolts, or other suitable fastening means. The end portions of the blacking box are tapered, as clearly shown in Fig. 4 of the drawings, the

terminal portions

14 and 15 of the side walls being converged outwardly. The blacking box is reinforced at the outer faces of the side walls by vertical flanges 16, extending outwardly to the of a companion applicaplanes of the outer edges of the bottom flange 13. The front wall is provided at the upper portion witha recess or opening 17, and the side walls have openings 18 arranged in pairs and located between the flanges 16, and adapted to permit a torch to be introduced into the blacking box to illuminate the interior of the molds so that the latter may be inspected from the top thereof.

The blacking box is equipped with a removable top 19, consisting of a plate provided with side and end flanges 20 and21, corresponding to the configuration of the walls of the blacking box, and adapted to flt on theupper edge-thereof, as clearly shown in Fig. 3 of the drawings. The side flanges 20 have terminal outwardly converging portions 22, corresponding to the side walls of the blacking box, and in order to enable the removable top to be readily placed in proper position upon the walls of the blacking box, it is equipped at the end angles formed by the side and

end flanges

20 and 21 with depending pins 23, provided with reduced shanks 24, which are headed and secured in perforations 25 of the top of the blacking box; The lower end portions 26 of the pins are tapered and facilitate easy and rapid placing of the top accurately upon the body of the blacking box.

The flask is a two-way flask, but the blacking. box may be constructed to support a single flask or a multiple flask, having any number of molding compartments. The top, which forms a flask-receiving seat, is provided with an elliptical opening 27 adapted to permit the blacking mixture dripping from the lower ends of the compartments of the flask to flow into the blacking box, which forms a catch basin. The side portions of the removable top project laterally beyond the side walls and extend to the planes of the side edges of the bottom attaching flanges 13. The blacking box 1 is shown in the accom an in drawin s for use in connection with pipe molding flasks, and in practicethe flasks are placed on and removed from the blacking box by the crane of a pipe pit.

In order to center the flask on the blacking,

box, the latter is equipped with centering devices 27, located at the corners of the top of the blacking box. Each centering device consists of an upwardly projecting lug 28. having an inclined inner edge or face and arranged centrally at the inner edge of a horizontal attaching plate 29, formed integral with the lug 28 and secured to the top ofthe blacking box by means of a bolt or screw 30. In order to enable a single fasten ing device to be employed for securing each of the centering devices to the top of the blacking box, the said top is provided in its upper face with approximately diagonal grooves 31, adapted to receive ribs 32,,

formed integral with the attaching plates 29 and depending from the lower faces of the same. The ribs slidably interlock the centeringidevices with the top of the blacking box, and the centering devices are adapted inthe process of construction to be arranged at different distances from the center of the blacking box to accommodate flasks of different sizes, and the blacking box may be changed to adapt it for a diflerent size of flask by simply removing the top plate and substituting therefor another having the centering devices, arranged in proper position to center the flask to be jar-red. The upwardly projecting lugs present inner inclined edges tothebottom of the :flask 4 and operate-to centerthe same on the blacking box, asthe flask is lowered onto the same. The blacking box, which is adapted to support the flask duringthe packing of the sand around the pattern by the jarring machine, enables the sand molds to be blacked while on the jarring machine. The blacking mixture is poured into the sand molds at the topin the usual manner, and that which runs from the lower ends of the molds is caught by the blacking box and discharged into the bucket 11.

Having thus fully described my invention, what I claim as new and desire 'to secure by Letters Patent, is
