if desired. Light springs 6 or other means are provided to constrain the channels to adopt positions with their lower ends slightly elevated in respect of stationary stops or projections 7 disposed beneath their extremities. These stops 7 may conveniently be formed on bars 8 extending across the machine and are adapted to register with slots 3 in the channels so that on depression of a channel or channels these stops 7 come into contact with and support the last piece of type which thus remains stationary whilst the other pieces of type in the channel are carried down with the channel, The channels thus operate like a series of keys and on depression of the key or channel in which the desired letter is stored, this operation causes the first or lowermost type of the series to project through the space or opening provided to a position between the finger and thumb and the type may thus be readily ex tracted for removal to the printers stick or chase. In order to prevent more than one type piece being extracted at a time the hole or space in or below the disc 3 is so proportioned so to' allow the passage only of the lowest type. On release of the key or channel the same is automatically returned to its correct position by means of the spring 6. A stop or projection 3 on the channel engaging the underside of the fixed stop 7 thus limits the upward movement of the chan- Instead of a separate spring for each channel or key I may, if desired, have one common spring for each row of keys, each row being interconnected in such a manner that on depression of any one key the whole row is automatically depressed and the lower most type in each channel of the series raised toa position convenient for extraction. The upper'parts of the bars 8 may be formed as j 7 shown at 8 to act as a guide when a key is depressed.

For the purpose of easy distribution of the type from the chase the upper portion of which'is shown in Fig. 5 I provide a distributing channel 12 as shown in Fig. 4

which is detachably mounted upon the frame 1 of the appliance. When distributing the type a thumb nut 9 on the chase (Fig. 5) is released to enable a sliding bar 10 to he slid down a short distance to create a gap or space at the end of the row of type; a bolt 9 working in a slot 11 in a fixed block 11. The distributing channel has a pin 12 therein which is adapted to fit within a hole in the chase and the row of type may then be transferred to the distributing channel. The channel is now released from the chase and its pin 12 placed within a hole on the pivotally mounted spring controlled tumbling block 13 on the typesetting appliance and supported by a pin 14 thereon. For distributing the type from the channel the said channel 12 is depressed and a fixed pin or projection 1 1 on a pivotally mounted guide 15 engages the lowermost type to rasie the same into a position convenient for extraction as heretofore described with reference 16 at each end of the appliance pivotally mounted at 16 to a bracket on the frame. To these levers the lower ends 8 of the bars 8 are mounted, the bar in communication with the lower row of keys being fixed to the plates 1 on the appliance since it is 1 unnecessary that this bar should move. A hinge 17 is secured to the frame and an operating handle 18 is mounted upon the free end of said hinge. It will be readily understood on reference to Fig. 1 that when the handle 18 is operated the levers 16 are moved to the position shown in dotted lines thus bringing all the rows of keys flush or level and to a position whence it will be easier to place the distributed type in the respective channels. The bars 8 in this movement are guided in slots in the plates 1 and stop plates 8 engaging the underside of the plates 1 are provided for limiting the upward movement of the said bars 8. It may be found preferable in practice with a View to avoiding any disturbance of th types as a consequence-of a too rapid or jerky movement to replace the lever movement by a screw of suitable pitch.

Extension channels 19 may be provided when desired for accommodating more type than one of the channels 3 will take.-

The discs 3 may have a symbol or-indication thereon indicating the character 01' type in the channel.

In order to ensure that the type in the channels does not assume a slanting position with the bottom of the type in the rear I may provide a rod, pin-brush Or the like to stroke or rub the bottom of the type in the direction in which they are travelling. This may be provided for by having a slot in the bottom of'th'e channel through which a rod pin or brush or the like works.

Instead of the stationary stop l1ereinbe-' fore referred to the stops may be carried by the channels so that when each channel is depressed the stop itself is raised by contact with the base or bedplate or I may employ stationary channels and separate keys. By depressing any desired key I may operate a rack or lever mechanism to raise the stop thereby lift the lower type.

in the corresponding channel and What I claim and desire to secure by Letters-Patent is:

1. A type setting appliance comprising a frame, means for supporting said frame at an angle to the horizontal, a plurality of channels adapted to contain type arranged side by side within said frame, a common rod upon which all said channels are pivoted by their upper ends, spiral springs connected between said rod and said channels for biasing said channels to elevated position, said springs encircling said rod, stops for limiting the upward movement of said channels disposed below said pivoted connection, finger pieces at the lower ends of said channel, openings adjacent said finger pieces, a fixed stop beneath each channel adapted to pass into its appropriate channel when said channel is depressed by the finger piece, said stop operating against the foot of a single type to insure its being extended through the opening adjacent the finger to a position where it can be readily withdrawn by the operator, substantially as specified.

2. A type setting appliance comprising a frame, means for supporting said frame at an angle to the horizontal, a plurality of channels adapted to contain type, arranged side by side within said frame, a common rod upon which all said channels are pivoted, spiral springs connected bechannel adapted to pass into its appropriate channel when said channel is depressed by the finger piece, said stop operating against the foot of a single type to ensure its being extended through the opening adjacent the finger piece to a position where it can be readily withdrawn by the opera tor, means for actuating all said channels to bring them all into alinement so that they lie flush and in the same plane, for facilitating distribution substantially as specified.

In witness whereof I afiix my signature.

CHARLES ASHTON HENRY BULLOCK.
