CARRIAGE-RETURN IVIECHANISM FOR TYPE-WRITERS OR THE, LIKE.

SPECIFICATION forming part of Letters Patent No. 784,585, dated March 14, 1905.

Application filed June 30, 1903. Serial No. 163,747.

To (all lull/0m, it rnru concern:

Be it known that I, LOUIS MYERs, a citizen of the United States, and a resident of Hartford, in the county of Hartford, State of Connecticut, have invented certain new and useuseful Improvements in Carriage Return Mechanism for Type-I/Vriters or-the Like, of which the following is a specification.

My invention relates to machines, such as typewriters, in which a traveling carriage is employed, and has for its object to provide a simple mechanism for returning the carriage to its original position after it has reached the end of its travel.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure 1 is a rear view of a type-writer having my improvement applied thereto. Fig. 2 is a side view thereof with parts in section. Fig. 3 is a sectional plan on line 3 3 of Fig. 2; and Fig. i is adetailed plan of the carriage-returning wheel, the spring connected therewith, and the carriage-rack which engages said wheel.

A in the case is the frame of the machine, and B a portion of the carriage, which travels transversely in the usual manner. This carriage is provided with a rack B in engagement with a carriage returning-wheel C. This wheel is secured to a shaft C, extending through a casing or drum 1), to which is secured one end of a spring E, the other end of such spring being secured to the shaft. This spring performs the function of the customary d living-spring to propel the carriage step by step as it is released by the escapement. Any suitable step-by-step feed mechanism may be employed. In Fig. 2 I have indicated the usual escapement-rack I, mounted on the carriage and working in conjunction with the feed-dogs J, mounted on the frame. In the structure shown, therefore, the carriage-return mechanism is ent1re1y separate from the step-by-step feed mechanism.

Upon the lower end of the shaft C is secured a bevel-pinion C in engagement with a bevel-wheel F upon a transverse shaft F. This shaft is provided at one end or at both ends with pinions F in engagement with sectors G, secured to rock-shafts G. Each rock-shaft is provided with a forwardly-extending arm G which has a pin-and-slot connection H with a key-lever H, fulcrumed at H H indicates the key at the front end of said lever.

It will be understood that when the carriage is at the beginning of a line the spring E is fully under tension, and as the carriage is fed space by space in the ordinary manner the tension of the spring gradually decreases, being, however, suflicient to feed the carriage to the end of a line. The operator then depresses either one of the keys H and thus rocks the corresponding sector G rearward, causing the shaft F to rotate and transmitting this rotation to the wheel C. The carriage is thus returned to its initial position, and at the same time the propelling-spring E is again put under tension.

In the preferred form of my invention above described the carriage-propelling spring is connected with the carriage-return wheel C through the medium of the shaft C. I desire it to be understood, however, that this connection is not absolutely essential. Various other modifications may also be made without departing from the nature of my invention.

1 have herein referred to the elements H as keys. This term, however, as used in the description and claims is not to be given any specific or restrictive interpretation, but simply means an element adapted to be engaged and actuated by the operator.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a type-writer or the like a carriage provided with a rack, a carriage-return wheel engaging said rack, a propelling-spring one end of which is connected with said wheel so as to be wound when said wheel is turned in the direction contrary to the step-by-step feed riage-returning key operatively connected with said sector.

3. In a type-writer or the like, a carriage provided with a rack, and a carriage-return mechanism separate from the step-by-step feed mechanism, said carriage-return mechanism comprisinga wheel engaging said rack, a shaft on which said wheel is mounted, a bevel-gear also mounted on said shaft, a transverse shaft, a bevel-gear mounted on said transverse shaft in engagement with said first-named bevelgear, a pinion on said transverse shaft, a rocking sector in engagement with said pinion, and a carriage returning key operatively connected with said sector.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS MYERS.
