MACHINE FOR MANUFACTURING CRAYONS, CARPENTERS CHALK, dc.
SPECIFICATION forming part of Letters Patent No. 437,752, dated October '7', 1890.
Application filed June 6,1887. Renewed Deciember 3, 1888. Serial No. 292,440. (No model.)
To all whom it may concern: Be it known that I, JOHN S.- CowDERY, a
citizen of the United'St-ates, residing at San-' dusky, county of Erie, and State ofOhio, have invented certain new and'useful Improve-.
ments in Machines for Manufacturing Cray-j ons, Carpenters Chalk, or other Like'Articles and I do hereby declare the following to be a description of the same and of the manner of constructing and using the invention in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, forming a part of the specification, the
principle of the invention being herein exr connecting together thedifferent mold-plates the form of links shown in Fig. 6.
in my improved machine for crayon-making.
Referring to the drawings, Figure 1 is a plan view of a series of mold-plates connected together by one form of my improved links, certain parts being broken away and the moldplates in closed position. Fig. 2 is an elevation view of a series of links of the same form as those shown in Fig. 1. Fig. 3 is a perspective view of one link of this form. Fig. 4 is a plan view of another form of securing the mold-plates together certain parts being broken away and the mold-plates in closed position. Fig. 5 is a perspective view of the end portion of a mold-plate of the form shown in Fig. 4. Fig. 6 is a plan view of a series of links and mold-plates, the latter being in closed position, the links rep resenting another form of the invention, certain parts being broken away. Fig. 7 is a perspective view of Fig. 8 is a plan view of the parts shown in Fig. 6, the mold-plates being in open position, certain parts being broken away. Fig. 9 is a perspective view of still another form of link.
Fig. 10 is a plan view of aseries of links similar to that shown in Fig. 9 and mold-plates connected therewith, the latter in closed position, certain-portions being broken away. Fig. 11 is a plan view showing the same parts as shown in Fig. 10, the mold-plates being open. Fig. 12 -is a detail plan of one moldplate frame with the mold-plates and links in closed position, the form of the link being the same as that shown in Figs. 6, '7, and S. Fig. 13 is a detail in vertical cross-section of one of the mold-plate frames, omitting certain of the connecting part-s. Fig. 11 is a vertical elevation of a series of links and mold-plates on the lineman of Fig. 8, the mold plates being in section and in open position. Fig. 15 is a vertical elevation similar to Fig. 14, taken on the dotted line w or of Fig. 6, the mold-plates being in closed position.
Referring to Fig. 1, Arepresents the moldplatcs provided with the shoulders a a and the tenon b. The link B is provided with the tongue 0 on its one edge and with the opening 0 opposite thereto, in-which the tongue of the next su'cceedinglin'kis placed. The link is provided with the shoulders 61 d, and in the vertical opening d between said shoulders the tenon b of the respective mold-plate closely fits, the shoulders a a of the respective mold plates' having bearing against the shoulders d d of the diiferent links.
In the form of mechanism shown in Figs. 4: and 5, connecting the respective links of the series, eachmold-plate A is provided at each end with the vertical shoulder e on one side of its longitudinal face and on the opposite side with the rectangularly-formed vertical hook e, in the opening 6 of which the shoulder of the next succeeding mold-plate fits.
In the formshown in Figs. 6, 7, and 8 each mold-plate is formed at each end portion with the two vertical shoulders f f while the link in this form is provided with three shoulders, two of which g g are respectively formed at the upper and lower face portions of one edge, and the third g is formed on the central face portion of the opposite edge. Between the two shoulders g g is the space 9 in which the shoulder g of the next link of the series fits. Between the two shoulders ff is the opening f When the mold-plates and links are in closed operative position, as shown in Fig. 6, the inner side f of the shoulder f of each mold-plate has rigid engagement with the shoulder g of the corresponding link and with the shoulders g g of the next link of the series,while the inner side f of the shoulder f has engagement with the shoulders g g of the corresponding links when the links and mold plates are in open operativeposition, as represented in Fig. 8.
In Figs. 9, 10, and 11 the links are formed with the two vertical shoulders h h extending unbrokenly from the upper to the lower portions, while the mold-plates are the same in form as the mold-plates represented in Figs. 6 and 8. Between the two shoulders h h is the opening 72.. The shoulder f of one mold- .plate and the shoulder f of the next succeed-' ing mold-plate of the series fit in this open ing h; or, in other words, in the opening f formed between the two shoulders of each mold-plate in the form as shown in Figs. 10-
and 11, fits the shoulder h of one link and the shoulder h of the next succeeding link of the .series. When the mold-plates and links are in closed operative position, as shown in Fig. 10, the shoulder f of one mold-plate engages with the shoulder h of its corresponding link, the shoulder f being free from engagement with the shoulder h of the link. When the links and mold-plates are in open operative position, as shown in. Fig. 11, the shoulders h h of one link respectively have rigid engagement with shoulder f of one mold-plate and shoulder f of the next succeeding moldplate of the series.
The particular advantage which I gain by lessening the size of the links and reducing the number of shoulders in said links over the form of links set forth in my said application, Serial No. 148,635, is that when the mold-plates are in open position, as shown in Figs. 8 and 11, the shoulders of the moldplates are in rigid engagement with the shoulders of their corresponding links, whereby any shuffling or lateral displacement of the mold-plates (when in this open position) is prevented, and they are held rigidly apart from one another, thus allowing the crayons formed in the mold-plates to be easily removed without danger of breakage to the crayons. By the form of links shown in Figs. 5, 7, and 9 I am enabled also to remove any one mold-plate or link of the series without displacing the remaining links or mold-plates, and by the use of the form shown in Figs. 1, 2, and 3 I may easily remove any one link by displacing but three mold-plates of theseries.
The maintenance of the respective moldplates in rigid position when open is the re sult of the described construction, which operates to allow the independent play of movement of the parts, said play being equal to and no more than the distance through which a mold-plate is moved from its companion moldplate in order to release the articles molded between the two, such described construction resulting in the respective parts to and no more than the distance required to move one mold-plate to release its molded articles, multiplied by the number of moldplates in the series.
The various forms of mechanical construction set forth in this application are all comprised under the generic principle of invention set forth in my said prior application, Serial No. 148,635, these mechanical forms illustrating some of the modifications of which the principle of invention of said prior application is susceptible. It will therefore be understood that said broad principle of invention, necessarily shown in the different mechanical forms set forth in this application, does not constitute a part of the latter,
and that all claim upon said broad principle of invention is rested in said other application, Serial No. 148,635.
I claim-- 1. In a machine for the manufacture of crayons, carpenters chalk, or other like articles,
the combination, with a series of mold-plates, of mold-plate-actuating hook mechanism, said parts being constructed substantially as set .forth, whereby shuffling or lateral displace- .ment of the mold-plates when in open posi tion is prevented, substantially as set forth.
2. In a machinefor the manufacture of crayons, carpenters chalk, or other like articles,
, the combination, with a series of mold-plates,
of mold-plate-actuating hook devices interlocking with the latter, said parts constructed substantially as set forth, and having a relative play of movement equal to and no more than the distance required to move one moldplate from another sufficiently to release the articles molded between the two, substantially as set forth.

IIO
of mold-plate-actuating hook devices engaging therewith,said parts constructed, substan tially as set forth, with interlocking portions having a certain play of independent movement,,said play equal to and no more than the distance which a mold-plate is moved from its companion mold-plate to release its molded articles, substantially as set forth.
4:. In a machine for the manufacture of cray ons, carpenters chalk, or other like articles, the combination, with a series of mold-plates, of mold-plate-actuating hook devices engaging therewith, said parts constructed substantially as set forth and respectively having a certain independent play, said play in aggregate being equal to and no more than the aggregate of distance required to move one mold-plate to release its molded articles, multiplied by the number of mold-plates inv the series, substantially as set forth.
5. In amachine for the manufacture of crayons, carpenters chalk, or other like articles,
the combination, with a series of mold-plates,
