OLUF TYBERG, OF BROOKLYN, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 749,000, dated January 5, 1904.

Application filed May 8, 1897. Serial No. 635.681. (Nr model.)

To all whom, it may concern.-

Be it known that I, OLUF TYBERG, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mechanical Movements for Printing Devices, of which the following is a specification.

This invention is applicable in all cases where it'is desired at a given instant to maintain at rest a point upon the surface of a wheel orcylinder, whether for taking impressions, asin type-writing machines, or otherwise, and is applicable to printing-telegraphs as well as to type-writers.

The invention involves a new principle or mode of operation of printing devices embodying a rotating type-wheel or printingwheel, means for obtaining impressions from the characters thereon, and means for at will selecting the characters or types from which impressions are to be taken.

It consists, generally stated, in an organization, comprising a wheel revolving about its axis and having types fixed upon'its face, respectively, in permanent radial relation thereto, combined withrotary wheel-driving devices continuously revolved and having permanentinterlocking orintermeshing positive driving connection with the type-wheel and yet so constructed and operating that any printing-point upon the surface of the type wheel may at will be caused to assume a position at rest, or substantially so, with reference to a printing-plane in which succeeding impressions are to be taken. This is accomplished in the embodiment of the invention herein specifically described by a compound motion which consists of the rotary motion of the wheel about its axis and a bodily motion of the wheel at right angles to its axis in a direction opposite to the motion of that side of the wheel from which the impression is to be taken and occurring at the moment of impression, the axis of the wheel being stationary at other times.

. In the accompanying drawings, Figure 1 is a plan view of the machine. Fig. 2 is a side View, and Fig. 3 a front View; Fig. 4, a diagram showing the mechanical movement involved.

A is a base-plate having two upright projections A and A upon which is mounted in centers at and a a rocking frame B. This rocking frame B has two arms I) and b projecting toward the rear of the machine and which form the bearings for the type-wheel shaft c,andanotherdownward-projectingarm 13 To the one end of the type-wheel shaft 0 is fastened'a gear 0 which engages with a pinion b fastened to pulley b. This pulley b is mounted freely on the hub of the rocking frame B and may be driven by a belt by some convenient power, motor or treadle, and when so driven will keep the type-wheel shaft 0 continually revolving. To the type-wheel shaft 0 and between the armsb and b is fastened a drum 0 having a series of projections or pins 0 arranged spirally on the circumference. Beneath said drum 0 are arranged a series of key-levers D, pivoted on a common rod D, which is fixed in lugs A which are supported by or form part of projections A and A The levers D are arranged so that each one is directly in line with acorresponding pin'c of the drum 0 The keylevers D are provided with keys and in their normal positions are held up against the cross piece a' (fastened to the front of projections A and A by springs d, mounted on anglepiece a which is also fastened to the front of projections A and A and which also acts as a limit-stop for the motion of the keylevers D. On the other end of the type-wheel shaft 0 is mounted the type-wheel E, which is revolved by the type-wheel shaft 0 by means of a key 0 while it is free to move longitudinally back and forth on the shaft 0. The type-wheel E has two rows of letters or types fixed thereon, each type in permanent radial relation to the axis of the wheel and the type in each row corresponding in number to the number of pins 0 on the drum 0 The number of rows, as well as the number of letters on each row of the type-wheel, may be varied to suit requirements. The typewheel E has a flanged hub e, into which is fitted an arm F, pivoted on ashaft F, mounted in bearing A which is a part of projection A. To the other end of shaft F is fastened a key-lever G. To the lower end of arm F is attached a spring F which tends through the arm F to keep the type-wheel E normally against the flange c on the end of the type-wheel shaft 0.

Directly in line with the inner row of the type-wheel Eis mounted ahammer H, pivoted to shaft h and mounted in bearing A which forms part of the base-frame A. To the other end of the shaft h is fixed an arm H, which through the rod 72, is connected to the arm Z1 which forms part of the rocking frame B. A spring h attached to arm H, keeps the hammer H, as well as the rocking frame B, in a normal position, all resting against the pin g, mounted in projection A.

The operation of the machine is as follows: The type-wheel shaft 0, carrying the typewheel E and drum 0 is continually revolved in the manner already described. On the depression of one of the key-levers D the rear projection or arm d will move into the path of its corresponding pin 0 of the drum When the pin strikes the arm (1 the power transmitted through the type-wheel shaft to revolve the type-wheel and drum will at once begin to lift the type-wheel shaft, and in so doing will enable the pin 0' to slide ed the arm (1 Referring now to the diagram, the projection on the drum is indicated by c and the outline of the type-wheel in its normal position by E, with its center in 0, while a a indicate the center of the rocking frame in which the type-wheel is mounted. When the projection or pin on the drum strikes the key-lever arm (1 the type-wheel shaft 0 is moved into the position c thus allowing the pin 0 to slide off the arm (1 from n to W. It will now be seen that as the distances from the point p on the circumference of the typewheel E to the points n and n on the arm d are equal, as well as the distances of p to c and 0 the point 19 will remain stationary during the engagement of the pin 0 with the arm d By the movement of the rocking-frame center from c to 0 an impulse is given to the hammer H through its connection with this rocking frame and which will make it strike the pointp of the type-wheel E while it remains at rest relative to the printing-plane.

Through control of the key-lever G either row of letters on the type wheel may be brought into line with the hammer H.

It is apparent from the comprehensive character of this invention that I do not limit myself to the organization shown, since it is obvious that the principle of operation herein set forth may be embodied in a large variety of mechanical forms.

When a wheel continuously rotated by a rotating driver has a bodily movement imparted to it at right angles to its axis, a point on one side of the wheel will remain substantially at rest or have a rolling or pivotal movement with reference to a given point at its periphery, the behavior being similar to that of a wheel rolling upon a surface when each point upon the periphery remains momentarily relatively at rest with reference to corresponding points on the surface upon which it rolls.
