MAGAZINES
The magazine is the receptacle in which a font of matrices is stored on the machine, ready for instant use as the matrices are desired in assembling a line. Some of the main features of the different model machines are the number of magazines carried on the machine at one time, the size or width of the magazine, and the manner of removing the magazines.
The magazine or channel plate consists of 92 channels milled in the brass plates, which guide the lugs of the matrices and keep them in line, so as to pass the escapements one at a time. Model 1 magazines have the old style channel entrances, attached to each magazine frame. The model 1 magazines are narrow, and will only carry matrices up to and including 11-point. The escapements of this model are fastened directly to the magazine.
The magazine for a model 2 or 3 machine is practically the same as a model 1 in construction, with the exception of being two inches wider at the lower end.
The verges on these models are practically the same as on the model 1, but on account of the difference in width of the magazines, are thicker. In this style the verges are locked by turning the grooved escapement verge locking bar one-fourth of a turn. This is turned by the crank at the right-hand side of the magazine. The keyboard is locked with a bar the same as the model 1.
The channel entrance is similar to the model 1.
The lower magazine of the model 2 is shorter than the upper magazine. The matrices are released by the same keyboard mechanism. The escapements, however, are on the top of the magazine instead of beneath it. Each keyrod has a lug fastened to the back end of it, which engages the escapement levers connected to the escapements. When the lower magazine is being used, the keyrod is raised and allows the verge spring to operate the escapement, releasing the matrix. The keyrod spring pulls the escapement lever down. This lever brings the escapement into position, ready to release another matrix.
The escapements on both magazines are capable of movement, as the verge springs of both tend to raise the escapements, but are prevented from doing so by the keyrod spring. The matrices are prevented from escaping from both magazines at the same time by a pair of grooved rods, which lie between the verges and the magazine. The locks on these rods are so arranged that the locking of one escapement unlocks the other, the movement of these being controlled by a hand lever at the right of the face plate, directly above the keyboard.
The model 3 magazine is the same as the model 2 (upper). The escapement action is also the same.
The upper magazine of a model 4 is a removable magazine which is independent of the escapement mechanism or the channel entrance. This magazine is as wide as the model 2 or 3, but is not interchangeable with them. This magazine is interchangeable with those of a model 5, 8, 14, 18, 19, or 14-s-k.
The lower magazine of a model 4 is the same as a model 2, but it is easily removed from the machine, as the escapement mechanism is independent of the magazine.
The escapement on the model 4 is the same as on the model 2, except that the escapement mechanism is fastened to the machine brackets instead of to the magazine.
On models 2 and 4 there are two channels of lower case “e” matrices. The mechanism for the operation of the double “e” is one keyboard cam to be connected alternately to the two short keyrods which connect with the two “e” verges. The shifting of a short keyrod from one to the other keyrods is accomplished by the raising of the assembling elevator, which operates a lever fastened to the assembling elevator link. This link comes in contact with a pawl and ratchet that operate the short keyrod by shifting alternately. This attachment can be applied to any model of machine.
The model 5 is a quick change machine. The magazine changes from the front and can be lifted off by one person. The escapement mechanism is separate from the magazine.
The model 5 magazine is the same as the model 4 and is interchangeable with any of the above mentioned models except models 1, 2, or 3.
The No. 5 (English) magazine is now known as the standard magazine. This magazine is used on all models 4, 5, 8, 14, 14-s-k, 18, and 19 machines.
The model 8 machine carries 3 of these No. 5 magazines. All magazines may be changed from the front of the machine. The magazines are interchangeable as to their position in the machine. They are also interchangeable with the same No. 5 magazines on other machines.
The model 14 is the same as the model 8, except that it has an auxiliary magazine.
Model 18, which carries two magazines, uses the same magazines as a model 5, 8, or 14. The escapements are hung to the magazine frame, but are like the model 5, 8, or 14 escapements, and are held in place by two spring clamps that fit over the top of the magazines at the front. By shifting a lever at the right of the magazine frame, the position of the magazines is changed.
The model 19 is the same as the model 18, except that it has an auxiliary magazine.
