Specification of Letters Patent.

Patented July 18, 1922.

Application filed'April 29, 1921. Serial No. 465,596. i

To all whom it may concern: I

Beit known that I, JO N -'W. PECKHAM, a citizen of the United States, residing at Parkston, in the county of Hutchinson and which they may make stereotypes for the purpose of printing the subjects of said matrices in their periodicals.

Various Ina chines have been devised for casting such stereotypes, but all such machines with which I, ammfamiliar, are of more or less complicated construction, and because of their price, arenot available to printers of newspapers and periodicals of small circulation, such as those printed in rural districts.

To the end that the job or other small" printer may take advantage of themat service above mentioned, withoutthe necessity of providing himself with a'casting machine,

I have devised a frame for casting typehigh stereotypes, this frame being of simple and inexpensive construction and -capableof being used upon an ordinary job press, so

that when the press is adjusted toprinting position. the platen and bed thereof Will form sides for said frame, andthereby provide a mold cavity into which type metal may be poured upon a mat to form a typehigh stereotype.

To this end the invention comprises a frame having top and bottom members and end members, the top and bottom members being grooved upon their inner faces at intervals throughout their length, said grooves being adapted to receive complemental tongues upon the ends of adjustable intermediate members adapted to form within said frame a mold cavity of such dimensions'as to provide'a stereotype?thatwill fit within the space in a form or galley provided for "it, the top member: of such frame being detachably connected to the end members thereof so that" when the;

frame is positioned for casting} this top membermay be removed for the purpose of allowing the molten'type metal to be poured into such mold cavity, ceed now. to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a perspectiveview of the cast ing frame. Fig. 2 is an enlarged fragmentary perspective view illustrating the arrangement and relative sizes of the top or bottom member and the intermediate memall as I will pro' bers. Fig. 3 is a fragmentarydetail showing the method of attaching the top member to the end members.

The frame comprises a bottom member 1 and similar end members 2 and 3, sultably secured to the bottom member to form a Attached to the end members 2 and 3 by means of slot and tongue rigid frame.

joints 4 is the top member 5, this top memher being removably connected to the'frame by means of pins 6 or the I like passing v through. the slot and tongue joints l.

The top and bottom members'are formed preferably of type-high brass rule, eighteen points or one-quarter of an inch in thick-v ness; and their, inner faces are. provided at regular intervals throughout their length with grooves 7, these grooves being preferably six points or onehalf pica or one;

tivelfth of an inch in width and depth. the preferred form of my invention these grooves are spaced apart two picas, or onethird of'an inch, from the face of one to the corresponding face of the next. thereby leaving a space between grooves of one end one-half picas. The grooves in the top member are arranged in the same relative position to the ends of the frame as the grooves 1n the bottom member. so that lines passing from top to bottom of the frame through corresponding grooves in the top and bottom members will lie in parallelism with each other and with the ends of the frame.

In order thata space may be blocked off within the, frame, of suchdimensions as X will provide a stereotype of the propersize f to fit the space provided forit in a form,

I utilize intermediate members Sand" 9. 'Each of these vmembers is provided at its 1 ends with tongues 10 of dimensions corresponding to the dimensions of the grooves 7 and pted t9 t therein as shown. The

55 inn revolution.

65 frame again placed uponthe platen 5 half pieas. or one-fourth of an inch in thickness. and the tongues of each of these members are arranged so that oneof their faces lies in the plane of the side of the mem ber. thus leaving. in the member 8. a pro- 1 jecting portion atthe side of the tongue of one-half pica. or one-twelfth of an inch. and on. the member 9. of one pica, or one-sixth of an inch. It will thus be seen that the combined thickness of those portions of the 5 intermediate members not included in the width of their tongues. is one and one-half picas. or the total space between grooves. Therefore by proper arrangement of the intermediate members 8 and 9. and by turn- 0 ing' them face for face or not as is necessary or desirable, any measurement may be had for the space between them in units of two pica". pieas and half picas. Thus. for example. a person desiring to cast a stereotype cut twenty-five ems wide can do so by inserting the members 8 and 9 in grooves in the top and bottom members a distance equal to twenty-five ems apart to form the box or casting space between the two members. if

' then he wishes to make the space twenty-live and a half ems wide. this can be done by changing the member 8 side for side. Thus any measure desired can be obtainedb v a proper manipulation of these two mtermed ate members.

As one method of forming type hig'h stereotypes by the use of my. frame I will describe the procedure followed when the frame is used with an ordinary job press.

40 which method is substantially as follows;

T he'operator first removes the grippers. and removes the tympan from the platen of the press. thus'learing both bed and platen jbare; He then applies a fresh tympan of clean white paper'and inserts under the lower tyinpan bail a piece of thin brass rule to act as a support for the casting "frame to restv upon when the tymi ian ismo'red to impression position. Then one side of the casting frame is inked and placed with that sideaoamst the tympan and with the bottom meml'ier. it resting against the support. Then the inknm rollers and dish are removed from the the frame upon the .tympan not even and uniform. the press ismored to impression positionandthe impression screws are adjusted until an even clear impression of the 6 0 framegis made upon the tympan. vThen the frame and tympan are removed.

The intermediatemembersof the frame are inserted in -l'he desired position ..Tf(l the pressand itis operated through a pr If the impression made by against the support. a piece of thin type high brass rule. preferably four points in thickness, cut to the proper length. is placed iii'thin thehidld cai it'y formed by the intermediate n'iembers and resting upon the bottom member so as to prevent the subsequently poured metal from entering the grooves T. and the press again moved to im-' pressionposition. Next the top member removed. by withdrawinnthe pins 6 and raising the top member oii? of the end members, h leanwhile, the type metal has been heated to such a temperature that it will turn white paper brown but will not burn it. andthis' metal is then poured into the mold carity and allowed to stand thus for approximately five minutes to heat the parts. \Vhilethis heating is taking place. the mat should be prepared in the usual way. by

warming and sprinkling its face lightly with French ehalkand brushing off the chalk with softcotton. qrhta-il piecelong enough to extend above. the top ofthe press bed should be pasted to the endof the mat.

.=\t the expiration of the heating period the press is backed up and the slug of metal removed; then the intermediate members and the top member are ireplaced inposition and the mat. isiuserted --beneath the frame with its back resting upon the platen and its face toward the mold cavity and the press is run forward again to impression po sition and metal-poured in as before. After the in'etallias cooled,suliiciently the pressis again backed up and the casting taken out. .l t will be foundthat this casting ,a. typelllQll solid metal stereotype. and the only things remaininggto hedone to it to prepare it f .u' use are thesawing off of. the t ,il .ii ece,.-plani-ng down; the edges. and routine. out airy-high spots. y

I

The top and bottom bars may be provided with a scale of figures; and pins 6 may be chained or otherwise secured to the top bar or elsewhere for preventing their loss.

Although my frame is herein described as for use particularly upon a job press or the like, I contemplate using it also upon any sort of casting bed, such, for example, as those beds upon which stereotypes are ordinarily cast.

I have herein described a specific embodiment of the frame of my invention, and have designated materials and dimensions, but it is to be understood that changes may be made in such details without departing from the spirit of the invention or the scope of the following claims.

What I claim is 1. A stereotype casting frame, comprising a top member, a bottom member, end members, and intermediate members, said top and bottom members being grooved upon their inner faces at equidistant intervals throughout their length, and said intermediate members provided with tongues at their opposite ends adapted to engage said grooves, whereby by adjusting said intermediate members relative to each other with their tongues engaging corresponding grooves in said top and bottom members, a rectangular mold space will be formed between said intermediate members and top and bottom members.

2. A stereotype casting frame, comprising a top member, a bottom member, and end members, said top and bottom members being grooved at equidistant intervals throughout the length of their inner faces, and in termediate members provided at their ends with tongues of dimensions corresponding to the dimensions of said grooves and adapted to be positioned between said top and bottom members with their tongues engaging said grooves to form a mold cavity within said frame.

3. A stereotype casting frame, comprising bottom and end members and a top member, said bottom and top members beingprovided upon their inner faces throughout their length with grooves spaced at equal distances apart in units of printers measure, and intermediate members having their ends formed with tongues of dimensions corresponding to the dimensions and adapted to fit therein, one face of said tommembers provided with of said grooves tongues lying in the plane of the face of said members and the other face thereof being set in from the opposite face of said members, whereby by turning said intermediate members face for face in said frame the width of the space formed between the said intermediate members may be varied.

4. A stereotype casting frame, comprising a top member and a bottom member and end members connecting same, said top and botgrooves spaced at equal length of said members, said. spaces being in units of printers measure or multiples thereof, and a pair of intermediate member's provided at their ends with tongues of dimensions equal to the dimensions of said grooves and adapted to fit therein to form a mold distances apart throughout the space within said frame, one of said mem- I bers being of greater thickness than the other and the tongues of said members being so arranged thereon that by manipulation of said members the space formed between them may be enlarged or diminished in units or spondingfaces thereof, and being one-half pica in width and depth, and a pair of intermediate members provided at their ends with tongues of dimensions equal to the dimensions of said grooves and adapted to fit therein to form between them a'mold cavity within saidframe, said intermediate members being respectively one pica and one and one-half picas in thickness andhaving their tongues so arranged that by turning them face for face with respect toeach other, the space between them may be increased or diminished in multiples of half picas.

6. A stereotype casting frame, comprising a top member, a bottom member, and intermediate members, means on the inner faces of said top and bottom members and on the ends ofsaid intermediate members whereby said intermediate members may be arranged within the frame formed by said top and bottom and end members to form a mold cavity, said top member being removable for D.
