TYPE-WRITING MACHINE.

' Application filed September To all whom, it may concern Be it known that I, RICHARD V. UHLIG, a citizen of the United States, residing in Rutherford, in" the county of Bergen and State of New Jersey, have invented certain new anduseful Improvements in Type Writing Machines, of which the following is a specification. This invention is. an improvement in line-- spacing mechanisms for typewriters. The usual pawl and ratchet line-spacing mechanism for typewriting machines enables the operator to space his lines apart a set or fixed minimum distance or multiples of that the operator desires to e distance--that is, to the usual regular extent. It frequently ha pens however that ect a fine alteration in the spacing of the typewritten lines in which event he must space the sheet by hand, depending upon his eye alone. j

The prmcipal object of my invention is to render it convenient in a machine having any line-spacing mechanism, for the operator to obtain minute regulation-that is, regulation complete, within extremes of adjustmentof the line-spacing when desired,

' as in feeding ruled sheets through the machine; whereby he is enabled either to space the typewritten lines at the intervals usual in typewriting machines, or to obtain variations and fine regulation of such intervals. To this} end I have combined, with the main spacing mechanism such as a pawl-and ratchet mechanism of the ordinary type, an auxiliary line-spacing mechanism, each mechanism being provided with an adjustment which in one case enables the operator to vary the line-spacing by unitary amounts or intervals in the usual manner, and in the other case, enables the operator to maintain any desired interval between the lines.

I provide, in addition to the usual unitary predetermined regular line-spacing mechanism, an auxiliary spacing mechanism including a supplementary clutch wheel for effecting fine variations in the line-space in terval, and a dog to rotate the clutch wheel, and adjustment being provided to control the throw of the dog. Either of the linespacing devices may be operated at will, by means of a single line-spacing lever-of the usual type. A tooth operated by said lever is shiftably mounted so as to'operate'either will.

Toshift the tooth to position to operate the clutching mechanisnu-I provide a switch actuated by lever, which also releases or withdraws the usual spring-pressed detent fromsaid ratchet wheel.

Big. 7 1s a detail perspective view of the switch, its lever and the detent-releasing arm.'

'Fig. 11 is a perspective view showing the conforclutching dog. Figs. 12, 13 and 14 are diagrammatic views illustrating the. positions assumed by the pawl when at rest, when first engaging the ratchet, and-when at, the end of its line+spaeing stroke respectively. Fig. 15 is a detail view-of the stop for the clutch and its adjusting mechanism. Figs. 16 and 17 are'views illustrating respectively the position occupied by the pawl when about to operate the clutch mechanism, and the position of the pawl when operating such mechanism. Fig. 18 is a detail view of the detent and its releasing mechanism.

A line-spacing ratchet wheel 3, fast on the axle 1, is engaged by the usual spring-actuated detent 4:, and as usual has invariable line-spacing teeth.

The minutely variable line-spacing mechanism comprises an annular flange or ring 14 rotating with the platen and. conveniently carried by the ratchet wheel 3, this flange clutch member comprises a constituting aclutch element of a frictional line-spacing mechanism. A cooperating carrier 15 rotatable around the ,axle 1 and having a clutching. dog 16 mounted to vibrate on the carrier, ,as'by means of a pivot pin 16 in alincment with the flange 14, the dog having a pair of jaws 17 to bite u on theflangeli, An interponent or transmission lever 20 is pivotally mounted upon the carrier in such manner as to engage the outer end of, the

When the finely variable clutching line-spacing mechanism is to be operated, the pawl is shifted out of operative relation with the ratchet wheel 3 by a switch 28, operated by-a'handle'29 pivoted on the axle. I

The free end of the switch-is beveled at 28 so that when the lever 29 is thr6wn'for-. wardly, such beveled edge, or cam will engagethe free end of the tooth 10 to shift orforce the same laterally out of operative position with the ratchet-and against the tension ofa spring 11.-- y A With the shiftingbf the tooth 1O 'outlo'f operative relation with the ratchet, the line-- spacing clutch mechanism becomes 0 erative'.- Conveniently, when the tooth is s ifted out of operative position relative to the ratchet, it is shifted into operative relation with the line-spacing clutch. mechanism, as shown in Figs. clutching dog and platen.
