DAVID S.v KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTI-IALER LINO'IYYPEA COMPANY, A CORPORATION OF YORK.

LINE-CASTING MACHINE.

Specication of Letters Patent.

Application led November 14, 1910. Serial No. 592,286.

To all whom it may concern:

Be it known that I, DAvm S. KENNEDY, la citizen of the United States, and a resident of Brooklyn, in the county of Kings and -State of New York, have invented a new and useful Improvement in Line-Casting Machines, of which the following is a specification.

My invention' has reference to line casting machines of the Mergenthaler type, wherein circulating matrices are delivered from a distributer downward through a curved channeled throat or entrance, into the upper end of an inclined channeled magazine, which is removable from the machine at will in order that it may be replaced by another containing matrices of a different font. In machines of modern design it is necessary to use at different times fonts in which the matrices vary greatly in width, those of one font being very much wider or thicker than those of another. When this change of fonts is made it is frequently necessary to use for the large matrices a magazine throat and magazine having very wide channels, less in number than those of other magazines.

The aim of the present invention is to provide for a speedy change of the throat or entrance when a magazine having channels of one width is replaced by another with channels of a different width.

To this end it consists in providing the machine frame with a throat movably secured thereto in such manner that it may coperate with magazines having channels of the ordinary width, or moved to such an inoperative position'that it will permit the replacement of the cooperating magazine by another having channels of a different width, and having a corresponding throat or entrance attached thereto.

In the drawings I have shown my invention applied in connection with the lower magazine of a machine such as represented in Letters Patent of the United States to Homans No. 830,486, dated Sept. 4th, 1906; but it is to be understood that it may be applied in like manner in any machine in which removable magazines are employed.

In the drawings: Figure 1 is a perspective view showing a portion of the machine with one throat hinged thereto and turned out of the operative position to permit the removal of the magazine with which it cooperatesthe magazine being shown partly withdrawn. Fig. 2 is a perspective view showing a second or alternative magazine and a throat hinged thereto,y both in operative position-the overlying distributer being broken away and shown in section, to expose the other parts to view. Fig. 3 is a perspective view showing the manner in which the throat hinged to the second magazine may be swung open to give access to the interior of the magazine without hindrance on the part of the throat which remains on the machine. Fig. 4l is a vertical cross section showing a magazine, and a throat permanently attached to the frame in operative relation to said magazine. Fig. 5 is a perspective view showing a thick and a thin matrix.

Referring to the drawings, A represents the rigid main frame of the machine, B the movable secondary frame secured thereon' to sustain the magazine.

C is the usual channeled magazine, which occupies, when in use, an inclined position as shown in Figs. 2 and 3. This magazine is removable at the rear of the machine in order that it may be replaced by another after the secondary frame B has been rocked backward to the position shown in Fig. 1.

D is a channeled throat or entrance through which the matrices descend from the distributer E into the upper end of the magazine. This throat D has channels of a width corresponding to those in the magazines most commonly employed; that is to say, narrow channels.

The throat is connected to the magazinesupporting frame B by horizontal pivots F, so that when the magazine C is in operative position the throat D may be turned upward to the operative position shown in Fig. 4, in order to receive the matrices from the distributer and direct them into the magazine, or turned downward and backward in order to give access to the upper end of the magazine and the under side of the distributer, and to permit the withdrawal of the magazine from the rear of the machine, as shown in Fig. 1, when a substitution is to be made. It will be observed that this throat D forms a permanent Patented Dec. 12, 1911.

part of the machine, and is designed to cooperate with magazines which do not have throats attached tO them.

When the magazine is to be replaced by one requiring a throat with channels of ditfereiit widths, the throat D is turned downward and backward to an extreme, and inoperative, position, as shown in Figs. vl, 2 and 3. rIhis permits the introduction of a second magazine, C having its throat or channel entrance D, hinged thereto at d. When this second magazine is in position it serves to support the throat D, which may be turned upward to the Operative position shown in Fig. 2, Or swung downward to give access to the upper end of the magazine, as shown in Fig. 3.

It is to be observed that the permanently attached throat D is so formed and hinged that it may be swung downwardto the extreme position required to permit the Opening of the throat D. In other words, it possible in the construction shown to Open the throat D without removing the throat D from the machine.

Having described my invention, what I claim is:

l. In a line casting machine, a frame adapted to sustain a removable magazine in combination with a magazine throat hingedl thereto, and adapted to coperate with a magazine, said parts being constructed and arranged to admit of said throat swinging to an inoperative position, together with a magazine having a throat hinged thereto, the two said throats being provided with channel entrances of different size.

2. In a line casting machine, the combination of a magazine supporting frame B, and a throat D hinged thereto, with the magazine C having a throat D, said throat D being arranged to swing beyond the path of the throat D and the said throats D and D being provided with channel entrances of different size.

3. A line casting machine provided with a removable magazine and two magazine throats, One hinged to the frame and the other connected to the magazine, so that the former may be swung Out of operative position to permit its replacement by the latter.

A line casting machine having in combination, a distributing mechanism, a removable magazine and two magazine throats, one movably joined to the frame and the other connected to the magazine, so that the former may be moved out of Operative relation to the distributing mechanism to perinit its replacement by the latter.

In testimony whereof I hereunto set my hand this seventh day Of November, 1910, in the presence of two attesting witnesses.
