Specification of Letters Patent.
Patented Aug. 15, 1965.
Application filed July 20,1904. Serial No. 217,359.
.To all whom 'n1/Cty corte/3771,:
lle it known that I, Renner COLLINS, a citizen of the United States, and a resident of dan Francisco, in the county oli San Francisco and @tate of California, have invented a new and Improved Linotype-Irlouthpiece, of which the :following is a full, clear, and exact description.
lhe object of the invention is to provide a mouthpiece for the metal pot or crucible of a linotype-machine, by means of which mouthpiece to allow a better l'low of metal into the mold and also allow for the thorough venting' of the mouthpiece, thus preventing; defective slugs. li attain this object by certain novel features of construction, which will be fully set forth hereinafter and pointed out in the claims.
Reference is had to the accompanying' drawings, which show as an example a preferred embodiment of the invention, in which drawings like characters of reference indicate like parts throughout the views, and in which- Figure 1 is a sectional view showing a linotype pot and mold-wheel with my invention applied. Fig. 2 is an enlarged section showing the pot-mouth, the novel mold-piece, the mold, part of the mold-wheel, and a linotypematrix. Fig. 3 is an enlarged front elevation of the mouth of the pot, showing the mouthpiece in position. Fig. f1 is an enlarged front elevation of the mouthpiece with parts in section, and Fig. 5 is a cross-section on the line 5 5 of Fig. 4C.
ln Figs. 1, 2, and 3, 10 indicates the pot, having a mouth 10a. 11 indicates the mold-wheel, 12 the mold, and 14 a linotype-matrix, all of which parts are unaltered by my invention. The mouthpiece 15 lies in the mouth 10L and is to be secured by any desired means, preferably by bevel ing the side edges of the mou thpiece and engaging therewith and with the mouth 10 bevel-keys 16. 'lhe mouthpiece is formed with a slot17 extending continuously through it, except that it is broken at one or more points by bridges 18, which span the slot to strengthen the mouthpiece and prevent warping thereof. ',lhc slot 17 is strictly continuous at its front side, the bridges lying at the rear side of the slot, and the arrangement of said bridges is such that they do not interfere with the substantial or practical continuity of the said slot. This slot is adapted to have the metal forced through it into the mold, and by means of said slot a free unobstructed flow of metal is allowed, producing a solid slug and permitting all of the metal required quickly to flow into the mold. The face of the mouthpiece is formed with a number of vertical grooves 19 extending from the bottom of the mouthpiece upward to a point near the top, where they respectively meet horizontal pas ages 20, extending' rearward into the mouthpiece and communicating with a longitudinal passage 21, which extends through the mouthpiece from end to end thereof. This passage 21 may be formed in any desired manner, but preferably by milling out the rear of the mouthpiece and then closing the passage formed by a plate 2.2. (See Fig. 5.) The grooves 19 and passages 2O and Q1 form effective vents from the face of the mouthpiece to each end thereof and allow all gases to escape from between the mouthpiece and mold, thus avoiding blow-holes and other defects in the slugs. T he openings 20 are relatively minute, and their size, while suflicient to carry ol'l the air and gases, as explained hereinbefore, tends to prevent the movement of metal into the passage 2.1. Should metal pass the openings 20, however, the temperature of the surrounding parts keeps the metal in aliuid state, and as the air and gases blow through the openings 20 and passage 21 they will carry out such metal as may enter the passage, thus keeping' it clear and permitting it to serve its purpose elfectually.
With the mouthpiece thus constructed not only do l. provide for a copious and unobstructed tlow of metal into the mold, but l also completely vent oil' any gases which might otherwise .form blow-holes or other defects in the casting, thus allowing for rapid operation of the machine, producing at the same time the most effective slugs.
Various changes in the form, proportions, and minor details of my invention maybe resorted to at will without departing from the spirit and scope thereof. ,lflenee l consider myself entitled to all such variations as may lie within the terms of my claims.
Having thus described my invention, l claim as new and desire to secure by Letters Patentw 1. A linoty pe-mouthpiece having' a ventingpassage extending longitudi nall y therein from end to end thereof, and the passage communicating with the front face of the mouthpiece.
2. A. linotype-mouthpiece havingI a ventingpassage extending longitudinally through it from end to end, and communicating with the metal-passage in the mouthpiece.
3. A. linotype-niouthpiece having a longitudinally-extending venting-passage therein, a transverse opening" leading' from one side of the mouthpiece to the venting-passage, and a groove formed in said side of the mouthpiece and leading' from the metal-passage thereoitl to the said transverse passage.
et. A linotype-mouthpiece having' a slot extending' longitudinally therein and forming a metal-passage, a venting-passage extending longitudinally in the mouthpiece, transverse passages passing' from the venting-passage to one face of the mouthpiece, and grooves extending' from the transverse passages to the said metal-slot.
5. A linotype-mouthpiece having a slot for the passage of the metal, the slot running longitudinall)7 of the mouthpiece and being' continuous or unbroken at the front tace thereof, and a bridge-piece extending across the passage of the metal, the slot running longitudinally of the mouthpiece and being' continuous or unbroken at the front 'face thereof, and a bridge-piece extending across the slot rearward of its front face, for the purpose specified.
7. A linotype-mouthpiece having an opening therein for the passage of the metal, and also having a venting-passage extending longitudinally in the mouthpiece and open at one end thereof, and a passage extending from the venting-passage to and communicating' with the metal-passage at the Jfront face of the mouthpiece.
8. A linotype-mouthpiece having a long'itudinally-extending venting-passage therein, a tranverse opening leading from the front face ot' the mouthpiece to the venting-passage, and a groove formed in the front face of the mouthpiece and leading from the metal-passage thereof to the said transverse opening'.
In testimony whereofl l have'signed my name to this specification in the presence ot' two subscribing witnesses.
