The shoulder and seat of the lift should be kept free from gum or dirt so the matrices will not slip off while being raised. When the shoulder and seat of the lift wear so that it will lift two thin matrices or lift them crooked, the lift must be replaced by a new one.
The cam lever and lift lever are connected by a cushion spring which absorbs the movement of the cam lever, if the lever hangs up. There is an adjusting screw in the matrix lift lever which permits the lift lever to be raised or lowered.
The matrix lift must raise the lugs of the matrices clear of the vertical face of the box rails. If it does not do this, thin matrices, when being moved by the distributor screws, would be forced against the screws and become damaged. To adjust the lift, turn the distributor screws by hand until the cam roller is at the low part of the cam, place a thin matrix in the distributor box against the vertical face of the rails, then adjust screw until the shoulder of the lift is not more than 1/64 of an inch under the bottom of the matrix. The lift then should raise the matrix 1/32 of an inch above the top rails in the distributor box when the cam roller is at the highest part of the cam. After adjusting the lift, be sure that the adjusting screw locknut is tight.
The buffer of the distributor shifter should come in the box almost to the distributor lift, but should never come in far enough to engage the lift. The distance the shifter can travel into the box is regulated by a stop screw which sets in the shifter slideway. However, this screw sometimes gets broken off, comes out, or is worn off. This would allow the shifter buffer to engage the lift and cause undue wear.
Lower Distributor Box
For Models 2 and 4
On the upper distributor of a Model 2 or 4 the matrices are raised over the rails by the matrix lift, the same as on any other model. The upper portion of the inclined rails, however, are cut away. There is a bridge on the upper distributor box on which the matrices for the upper magazine ride until they catch on the distributor bar. The matrices for the lower magazines have a slot in the bottom so that they will not ride on the bridge. They fall from the upper box, through a chute, into the lower box, where they are separated and delivered to the lower distributor rail.
Care should be taken to see that the box escapements (or matrix lift) work freely at all times. If dirt is allowed to accumulate, the escapements will not work freely; the matrices will be prevented from separating and cause them to clog in the box.
To adjust the escapement pawls (or matrix lift) in a lower box, turn the screws until the matrix lift lever cam roll rides in the lower part of the cam. Adjust with the adjusting screw until the point of the male pawl clears the bottom of the slot in the matrix about 1/64 of an inch. See that the male pawl does not become bent; this point should admit a thin matrix only between both pawls. The female pawl must have a retaining hold on the matrix of at least 1/32 of an inch when the male pawl is adjusted to clear the bottom of the slot.
Distributor Box Matrix Lift Cam
This cam is fastened to the distributor back screw by means of a taper pin. There is no adjustment of the cam. It should not be detached unless badly worn, and then it should be replaced by a new one.
