PULLEY- PATTERN-MOLDING PRESS.
SPECIFICATION forming part of Reiasued Letters Patent No. 10,854, dated August 2, 188 7.
Original No. 842,Q39, dated May 18, 1986. Application for reissue filed June 15, 1887. Serial No. 241,417.
To all whom it may concern: 7 Be itknown that we, JOHN CYRUS WHEELER and MICHAEL COKELY, citizens of the United States, residing, respectively, at Flushing, in 5 the county of Queens and State of New York, and at Schenectady, in the county of Schenec t-ady and State of New York, have invented certain new and useful Improvements in Pul- V ley-Pattern-Molding Presses; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and
I to letters or figuresof reference marked thereon,-
which form a part of this specification.
Figure 1 of the drawings is a representation of a front elevation, partly in section. Fig. 2 is a bottom plan of plate L, and Fig. 3 is a perspective view of one of the prongs.
Our invention has relation to machines for molding pulleys, &c.; and it consists in the construction and novel combination of parts, as hereinafter set forth, and-pointed out in the claims.
Referring by letter to the accompanying drawings, X designates the bed-plate which supports the other portions of the machine.
A designates the base of the machine, which is provided with two vertical slots, A A, in
the opposite sides, through which project the press-arms C C, said press-arms C 0 being connected with the press'plate J by connectiug arms 2 and 3.
B is a vertical spindle or shaft, firmly secured to the bed, on which spindle slide the press-arms G C.
D D are arms which are secured to the rimpattern 4 5 by screws 1 and 2'.
top of the vertical shaft or spindle B to support the hub and halfarm pattern K.
H designates a rigid frame, and H anti-fric- 'tion wheels, under which worksthe inner end of the lever F, the outer end of said lever F terminating in a geared segment, F, which connects with a small pinion, F, behind the pulley G.
M M designate the flask, on the top of which E designates a plate, which rests upon the to press into the flask.
L is a plate with prongs 6 7 8 9 10 l1 12 13 attached, which plate is of the same diameter as the flask M M, which plate is designed to press and support the sand in the flask.
I designates a lever attached to the arms D D, which draws down the rinrpatt'ern after, the mold is pressed.
The mode of operating the device is as follows: After the rim-pattern 4= 5 has been projected, up through the base by means of'the lever I, the flask M M is put in place and filled with san'd to the top of the ring N N, which rests on the flask. The pronged plate L is then lowered (prongs down) into the sand. The press-plate J, which is hinged throughits arms 2 '3 to the press-arms CO",isthen brought directlyovertheplateL Poweristhenapplied to pnlleyG, and is transmitted through the pinion F to thelever F, which isdrawn down by the pinion and segment until the pronged plate L rests on the flask M M,whereit'is fastened after forcing the sand contained in the ring N N into it. The rinrpatteru is then drawn down by the lever I, the press released and swung to one side, the flask lifted away from the top of the base, (where the arm-pat- Aiter another half-mold has been made in the same way both are placed together, and are then ready to receive the metal.
In a finished machine it is intended that the movements of the parts he automatic, and any suitable mechanism may be employed to impart such motion to the parts.
The essential feature of the invention is the pronged plate. It is made of iron with the prongs attached. \Ve do not desire to confine ourselves to any number or shape of prongs, as the machine is designed to produce general foundry-castings, and must be governed by the form'of casting required. The ordinary way of making molds for pulleys and other castings of any size is to use cross-bars of wood or iron permanently fastened to the flask, around and between which cross-bars the sand is packed by means of a rainmer rests the ring N N, for holding sufficient sand tern is stationary,) and a half-mold finished.
in the hands of a skilled mechanic,the bars 10 bars in supporting it.
Theplate worksindependently of the flask, and isof any required shape-that is, either square, round, &c.-and adapted toany size casting. The prongs may be connected in the form of comb-sections, if desired-thatis, connected to a back or rib common to several or all of them. Near the center of the plate are several slots, S, which are to permit some of the sand to escape while pressing the pulley,
20 in order to prevent the mold from being too hard directly over the hub, and also to allow the gases to escape and the metal to enter the mold. The whole plate is simply a device for pressing and also supporting the sand in flasks of such dimensions as require something more to support the sand than its own consistency.
The ring N N is necessary for holding suflicient sand to make the mold of the requisite density after beingpressed. The ringN should 0 be a lap or split ring. so that the same may yield to the action of the plate L and allow the surplus sand to pass over the beveled edge a of the flask M.
It will be seen that by having the mouth of 5 the flask beveled outwardly edges are presented which will afford no means for the sand remaining thereon; but when the plate L is brought down will force the sand which cannot be pressed into the flask against the ring N and 0- allow the said plate to come down upon the mouth of the flask.
It will be noticed that the inner end of the lever F rests on anti-friction rollers under the frame H and shortens the distance between the 5 frame H and the point at which it is connected with the press-arms O C as the latter slide down the spindle or vertical shaft during the operation, thereby greatly increasing the power of leverage.
Having described this invention, what we claim, and desire to secureby Letters Patent, 1s-
1. The combination, with the bed-plate X, the slotted base, the vertical post B, with plate E and half-pattern K at its upper end, the ring N, flask MM, andpattern, of thepronged plate L, the press-plate J, the arms 2 3, connecting said plate to the press-arms G O, and the segment-lever F and gearing F substantially as specified.
2. The combination, with the bedplate X, the bars 2, the arms 0, the slotted base, the vertical post B, with plate E and half-pattern K at its upper end, the ring N, and-flask M, of the pronged plate L, having the central slots, the hinged press'plate, and the compression 'levers, as described, for compressing the sand in the flask, substantially as specified.
3. In a molding-machine, the combination, with a flask having an outwardly-beveled mouth, of a yielding ring arranged to engage the bevel, substantially as specified.
4. The combination, in a molding-machine, of a flask havingan outwardly-beveled mouth, a yielding ring, and a pronged plate adapted to move within the ring, substantially as specifled.
5. The combination, with aflask and the sand therein, of the plate L, provided with the prongs 6 7, &c., for pressing the sand into the flask around the pattern and for sustaining the molded sand, as set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
