MOTOR FOR BABY-ROCKERS.

SPECIFICATION formingpart of Letters Patent No. 613,037, dated October 25, 1898.

Application filed January 8, 1898.

To @ZZ wir/0m it may concern.-

Be it known that I, PERRY A. HERRINGTON, a citizen of the United States,residing at Hematite, in the county of Jeiferson and State of Missouri, have invented a new and useful Motor for Baby-Rockers, of which the following is a specification.

This invention has relation to means for rocking or vibrating a body, such as a babycarriage or cradle, and which may be used for operating light machinery, such as a fan, churn, or sewing-machine.

One of the principal features of the invention is to provide a motor of improved construction to be run by weight and in which the train of gearing, including the governor and frame, is disposed so as to reduce the friction to a minimum amount and enable the individual parts to be readily accessible for cleaning, oiling, and repairing.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacricing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a detail view showing the invention applied to a baby-carriage for imparting a rocking or vibratory movement thereto. Fig. 2 is a front view of the motor. Fig. 3 is a side view thereof. Fig. 4 is a detail view of the governor. Fig. 5 is a detail view of the ratchet-and-pawl mechanism between the drum and the gear-wheel mounted loosely on the shaft thereof. Fig. 6 is a detail view of the drum, its shaft, and the parts intimately connected therewith.'

Corresponding and like parts are referred to in the following description and indicated in the views of the drawings by the same reference characters.

The means for supporting the working parts of the motor consist of a horizontal frame 1, of oblong form, mounted upon legs 2, and a vertical frame 3, which is secured at its lower end to the side bars of the horizontal frame,

Serial No. 666,107. (No model.)

and this vertical frame has an inwardly-extending arm 4, which cooperates with the governor in the manner presently to be described, so as to check the speed of the motor in the event of the latter exceeding a predetermined number `of revolutions per minute. A bracket-arm 5 is secured to an end of the horizontal frame 1, and a lever 6 is fulcrumed about midway of its ends to the upper ex 6o tremity of the arm 5 and is counterbalanced by being provided with a weight 7 at its upper end. A crank-shaft 8 is connected by means of a pitman 9 with the lower end of the lever 6 and transmits motion thereto from 65 the train of gearing.

The winding-shaft 10 is journaled at its ends in the side bars of the horizontal frame 1, and one of its ends projects and is made angular to receive a key or crank, by means 7o of which the motor is wound up. Adrum 11 is secured upon the winding-shaft, so as to turn therewith. The driving-gear 12,mounted loosely upon the shaft 10, between the inner end of the drum 11 and a collar 13, is provided 75 outer end of the pawl being expanded, so as 8o to obtain an extended bearing against the in ner periphery of the ring 14. This pawl 1G has its inner end pivoted in a groove or notch in a side of the collar 13, and a spring 17, in-

terposed between the pawl and collar, holds the outer end of the pawl against the inner surface of the ring 14, thereby maintaining said pawl in operative relation. A cord, rope, or chain 18 is secured at one end to the drum 11 and passes upwardly over a pulley 19 at the 9o upper end of a standard 20, secured to a ta ble or support 21, and is weighted at its free end, the weight 22 being sufficiently heavy to operate the part to be driven. Agearwheel 23, secured upon the crank-shaft 8, is in mesh wit-h the train of gearing, actuated by means of the weight and driving-gear 12, and likewise intermeshes with a pinion 24, secured to a vertical shaft 25.

A plate or disk 26 is secured to the upper end roo of the shaft 25, and weighted arms 27 have pivotal connection therewith at diametrically op-v tional engagement with the inner end of the' arm 4, thereby retarding the speed of the motor. The lower face of the sleeve 28 is of approximately conical form, whereby the frictional contact between it and the arm 4t may be increased proportionately to the outward tendency of the free ends of the arms 27. The inner end of the arm 4t is formed with a circular opening to receive the lower conical end of the sleeve 28, thereby providing for the wedging of the said sleeve into the opening, so as to insure a checking of the motor should it tend to exceed a predetermined speed.

Inasmuch as the motor is designed, primarily, for rocking or oscillating a baby-car- -riage it is shown in this connection, although it is obvious that it maybe employed for other purposes and for driving any light machinery. In order that the body of the carriage may be operatively connected with the actuating mechanism, a clamp 29 is provided, and the upper portion of the carriage-body is gripped between the jaws of the clamp, the latter being provided with an arm having a journal 30, which makes pivotal connection with the outer end of a rod 3l, by means of which the clamp is connected to the lever 6.

The motor being suitably mounted is rendered operative by winding the weighted cord or the like upon the drum 11, and the rod 3l being engaged with the journal 30 of the clamp 29 the lever 6 will be vibrated by the action of the motor and the running down of the weight 22 and impart a rocking or vibratory movement to the carriage-body,

A sleeve 28 is slidably mounted A provision being had for such movement by the spring connections between the carriagebody and the axles common in this class of devices. The motor can be readily disconnected from the carriage by slipping the outer end of the rod 3l from off the journal 30 or removing the clamp 29 from the carriagebody, as desired.

Having thus described the inventiomwhat is claimed asnew, and desired to be secured by Letters Patent, is-

1. In a train of gearing, the combination of a vertical shaft in mesh with the train of gearing and driven thereby, weighted arms having pivotal connection intermediate of their ends with the shaft and rotatable therewith, a sleeve slidable upon the vertical shaft and having its lower end made conical, vertical links connecting the inner ends of the weighted arms with the said sleeve, and an arm secured at one end to the frame and having its other end terminating between.the ends of the vertical shaft and having a circular opening to receive the latter, the free end of the arm receiving the frictional impact of the aforesaidvsleeve, substantially as and for the purpose set forth.l

2. In combination, a train of gearing comprising a governor, a counterbalanced lever actuated by means of the train of gearing, a clamp having a journal, and a rod adapted to connect the journal of the clamp with the weighted lever, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

PERRY A. HERRINGTON.
