Abstract: 17,972. Hough, J. Sept. 5. Typewriters and like machines.-Relates to a rotating - dial machine, applicable for printing on boards or other flat surfaces, and in large type such as is used for address cards, announcements, newspaper bulletins, price tickets, and packing-case addresses. Figs. 1, 2, and 4 show the machine as arranged to print on paper on flat platen. A type-carriage D is adjustable laterally, for letterspacing, in a frame C adjustable along a framing A, for line-spacing determined by means of a. dog C<2> and notches a<4>. Inner and outer series of type-stems J, J<1> extend through circular plates I, I<2>, which are connected together and removably mounted on a screw plug 11, fitted in a plate H adjustable in the carnage D for type shift. The type-carrier is turned by hand to brings the characters under a spring- elevated plunger M operated by a lever L. The type-stems J, J' are, preferably, square in crosssection, and provided with tapered upper ends j<2> to fit in a socket m<1> in the plunger M, and each stem is supported by a spiral spring j<3>. The plate H is slotted at H<3> for the passage of the type. The carriage D is provided with a pawl F for cooperation with a spacing-rack c<13> on the frame C. The pawl F is pivoted on a rod d<3> connected to the lever L by bars N, Figs. 2 and 7, pivoted, on the lever L and engaging under a cross-pin d' in the rod d<3>. A spring o<2> bears on the pawfF, and springs o<1>, e<1> bear on a plate E, located on the rod d<3> above the cross-pin d'. The bars N have adjustable fulcra n<1> for varying the spacing. The typestems J, J' vary in length, for varying the stroke of the lever L and consequently, the spacing. Word-spacing is effected by bringing the space between any two type-stems under the plunger M, and depressing the lever L to the desired extent, guided by the clicking of the pawl F. The pawl F is lifted from the rack c<13> at the end of a line, and released on return of the carriage D, by means of a sliding plate G, having a screw-and-slot connexion g, g<1> on the carriage D, and formed with projections g<2> for engagement against adjustable stops 4, and a projection g<3> for engagement under the pawl F. An inking-pad H<1> is disposed between rims h, h<1> on the plate H. The type-carrier is depressed for inking, and is returned by means of a spring-supported plate H<4>. The depression can be effected by pressing on an ornamental cap 11<2> on the plug 11, and is effected at each operation of the lever L by means of lipped bars 0<1> on a pivoted double arm 0, under which the spring o' bears, the rod d<3> extending through a slotted projection on the arm O The plate H slides on ribs on the carriage D, and is held in the one position, for the outer stem J, by a spring 10, and moved into the second position, for the inner stem J<1>, by means of a bell-crank D<3>, which is retained in the depressed position by means of a pivoted spring- retained catch 8. The carriage D is provided with tongues sliding in grooves c<10> c<11> in the frame C, and the groove c<10> is formed with notches c<12> for removal of the carriage from the frame. The frame C is provided with handles C<1>, C<3>, and slides on rails a<3> on the framing A, and is removable for use on the -ground, a table, box, or other flat surface. The paper is fed from a roll B over a platen A<1>. and between feed-rollers b, b<1>, and is severed by a pivoted spring-retained knife B<1>. The spindle b<3> of the roller b<1> is provided with a handwheel b<4>. The platen A' is spring-supported by stems 3 and springs 3<1>, and the central stem is screw-threaded for vertical adjustment. Boards,- such as box tops, may be printed upon on the platen A<1>.
