The model L is a rebuilt machine along the same lines as a model 5. The magazine changes from the front the same as a model 5. The escapements are fastened to the intermediate brackets similar to a model 5.
To change a magazine on this model: Lock the matrices by inserting the locking strip, pressing it firmly in place. Raise the cam levers to positions, lift the front end of the magazine, and it will slide forward. By allowing the lower end to drop, the magazine will hang in a vertical position ready to be lifted off.
To remove the verges from this model it is necessary to use the locking rod that comes with the machine. This rod is similar to the one used on the model 1, except it has an extra strip at the top which raises the keyrods higher. Insert this strip in the hole in the keyboard post at the right; push through as far as it will go. This will lift the keyrods free of the verges; they can now be pushed back by releasing the latch that holds the upper keyrod guides to the verge pivot rod at the right, and pushing back on the guide. The escapements can now be removed by taking out the two screws, one at each end, and lift off dowel pins.
TO REMOVE A VERGE
Remove the magazine or escapements from the machine and place bottom side up on a bench or table. On a model 1, with a pair of duck bill pliers, straighten the bent ears on the verge partition which holds the narrow brass locking strip in place. Raise the strip to a point beyond the desired verge. (On the other models there is no strip to be removed.) Push out the pivot rod with another rod of the same size, until you reach the desired verge; separate the ends of the two rods and lift out the verge and its pawls. Verges are made in various sizes and care should be taken that a verge of the same size is used in replacing. Examine the verge and pawl to see that there is nothing to retard its free action. Examine the verge spring for wear at the point of contact with the verge. If the verge does not work freely the matrices can not drop properly.
Failure of Matrices to Respond
(Due to trouble above the keyboard)
When the matrices fail to respond to the touch and the keyboard and keyrods have been found to be working properly, the trouble may be due to: Dirty magazine, dirty matrices, bent or damaged lugs on the matrices, weak verge spring, bent verge pawl, bent verge plunger, broken verge, verge not making full stroke, magazine not aligning with the assembler front partitions, matrix laying flat in the magazine and holding others back, no matrices in the channel, battered channel, keyrod spring weak or off.
CLEANING A MAGAZINE
To clean a magazine, run out all the matrices into a galley and place the magazine in a convenient place for cleaning. Magazines which have the verges assembled on them should be placed with the bottom side up in order to prevent the dirt getting in around the pawls while cleaning. With a good magazine brush, clean all dirt and gum from the inside of the magazine. If the magazine is very dirty, first use a little good gasoline or denatured alcohol on the brush to cut all the gum loose. Brush the magazine and use the air until dry on the inside. Then polish the inside by applying a very small amount of graphite on the brush and rubbing briskly.
In cleaning a magazine, be sure that all the little dark spots, which show where the lugs of the matrices set in the magazine, are removed. These spots are gum which forms in the magazine, due to oil and dirt which are carried in on the lugs of the matrices. If these spots are not entirely removed it would be better not to clean the magazine at all. When they are merely loosened up by the cleaning, the matrices will be held back and will not drop regularly.
