LlNOTYPE-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 790,447, dated May 23, 1905.

Application iiled September 1, 1904:. Serial NoK 223.079.

To tu whom, it may concern:

curved guiding-channels, through which theyl descend into the upper-end of an inclined magazlne. The magazine consists of parallel plates having their opposing faces grooved to receive and guide the upper and lower edges of the matrices. The intermediate channels or guides delivering to the upper ends of the magazine are formed in a hinged frame, technically known as the channel-entrance. This frame may be turned backward in order to give access to the upper end of the magazine and theadjacent parts of the overlying distributer. It sometimes happens that when the channel-entrance is turned backward a matrix just released or on the point of being released will pass down into the upper end of the magazine and fall upon its side instead of properly entering the guiding-grooves at its edges. These matrices lying on their sides will slide downward into the magazine until arrested by the matrices therein. Their eX- traction is attended by a loss of time andfrequently by disarrangement of other matrices.

The object of my invention is to prevent say, between the paths traversed by the upright matrices-a series of vertical pins so located that while they permit the matrices to descend in their proper positions they will arrest the fallen matrices. These guard pins or stops may be made in any suitable form and applied in any suitable manner, the

. the magazine.

only requirement being that they shall prevent the matrices which lie on their sides from descending into the body of the magazine. In the drawings I have shown a series of stop-pins secured at their upper ends to a bar, so that they may be thrust downward through a series of holes in the top plate of This arrangement admits of their being instantly Withd rawn when the interior of the magazine is to be cleaned by a brush, according to the ordinary practice.

Referring to the drawings` Figure 1 repre-'l sents a vertical cross-section from front to rear through the upper end of the magazine, the channel-entrance, and thedistributer with my improvement applied thereto. Fig. 2 is a perspective view of the foregoing parts looking from the rear, the channel-entrance being shown in its open position and all parts shown -in section at one end. Fig. 3 is a top plan til they arrive over their appropriate magazine-channels.

C C are the parallel horizontal screws which engage the edges of the matrices for the purpose of carrying them along the distributerbar.

D represents the channel-entrance, having its upper surface divided by a series of parallel plates d into a series of channels or passages, into which the matrices fall when delivered by the distributer-bar. This channel-entrance is extended downward and forward in a curved line, so that the matrices may be delivered from its lower end directlyv into the upper ends ,of the magazine-channels.

E represents the magazine, consisting of the top and bottom plates e and e', spaced a suitable distance apart and provided on their opposing faces with the grooves or channels e2 to receive and guide the upper and lower edges of the descending matrices.

.So far as described the parts are of the ordinary construction and arrangement and operate in the ordinary manner.

The channel-entrance stands normally in the position shown in Fig. l, its upper edge in position to receive the matrices from the bar and its lower edge in position to deliver them into the magazine. Under normal conditions each matrix passing from the channel-entrance D into the magazine will be held and guided at its upper and lower edges, and thus maintained in an upright position, as shown in Fig. 2. When, however,the channel-entrance is swung backward on its hinge or opened, as shown in Fig. 2, a matrix will sometimes fall upon its side and enter the upper end of the magazine, as shown in the middle of the magazine in Fig. 2, its upper and lower edges failing to enter the grooves in the plates. It is to arrest these matrices in the upper end of the magazine and in such position that they may be readily removed that my improvement is designed. In the form shown it consists of a series of upright pins G, secured to -f a bar g, overlying the magazine and extending thence downward through holes in the top plate to the upper surface of the bottom plate, or practically so. These pins are located at points between the grooves or channels, or, in other words, between the paths pursued by the matrices, so that the matrices standing on edge in the proper position may pass between them without interference. The distance between the pins is such, however, that it is impossible for a matrix lying on its side to pass between them.

are consequently arrested at or near the upper The fallen matrices end of the magazine, so that they maybe conveniently and instantly' removed.

The essence of the invention resides in the employment of uprights or stops in any form which will permit the passage of the upright matrices, but arrest those which have fallen. They may be either removable, as shown, or they may be located permanently in position.

Having described my invention, what I claim isl. In a linotype-magazine, comprising a pai r of grooved plates to guidethe matrices on edge, stops arranged to arrest the fallen matrices.

2. In a magazine for a linotype-machine,the combination of two grooved plates adapted to 'guide the edges of the matrices, and stops, G,

to prevent the passage of the fallen matrices.

3. The combination with a magazine comprising upper and lower grooved plates, a removable bar, g, provided with a series of stoppins projecting into the magazine to arrest the fallen matrices.

4. In a linotype-magazine having grooves to guide the opposite edges of the matrices, removable stops to arrest the fallen matrices.

5. A matrix-stop for application to a linotype-maehine, consisting of a bar adapted to extend transversely across the upper end of the magazine, provided with pins of suitable length to project downward into the magazine to the surface of the lower plate, in order to arrest the fallen matrices lying on said plate.

In testimony whereof I hereunto set my hand, this 24th day of August, 1904, in the presence of two attesting witnesses.

ROBERT F. MERCER.
