SWINGING CRADLE.

SPECIFICATION forming part of Letters Patent No. 643,267, dated February 13, 1900.

' Application filed June 28,1899- Serial No. 722,168. (No model.)

and has for one object to provide a swinging cradle which is operated by a clock mechanism.

A further object is to provide a swinging cradle which can be operated without attention for any predetermined length of time and which is simple in construction, effective in operation, and which can be manufactured at a low cost.

To these ends the invention consists in a swinging cradle constructed and operated substantially as hereinafter illustrated and described, and defined in the appended claims.

Referring to the drawings, in which similar letters of reference indicate similar parts,

Figure 1 is a side view of the invention. Fig. 2 is a View in perspective of a detail of the construction.

In the drawings, A. represents the frame which supports the cradle 13 and comprises two standards a and a and a connecting-bar of. Suitable strengthening-braces a are arranged on each side of the standards to give the requisite rigidity to the frame. The upper ends of the standards a and a are bent transversely and then downwardly, forming a bracket or, which is perforated to receive a bolt 1), which serve as pivotal supports for the arms I) of the cradle 13. These arms B are securely bolted to the head and foot of the cradle and extend upwardly, the upper extremities of which are preferably curved so as to extend over the bracket a. The pivotbolts b pass through the curved end of the supporting-arms b and through the perforations in the brackets a and thus permit the free swinging or oscillating movement of the cradle. Upon the standards a is fixed a clock mechanism 0 of any ordinary or preferred form, the main spindle C of which terminates in a crank-lever C which is arranged so as to engage the inner sides of two segments D D, secured to a plate E, fixed to the cradlearm I). The segments D D are provided with a curved end portion, which are oppositely arranged, so that, as shown in Fig. 2, the inner sides form a recess or opening of substantially oval shape, in which the crank-lever C works. The segments are secured to the plate E by means of threaded bolts passing through the straight portion of the said segments, and the said bolts extend through transverse slots formed in the plateE and are provided upon their inner ends with binding-nuts by means of which the said bolts may be fixed in their adjusted position. By means of this construction the segments D D are capable of being adjusted so as to vary the size of the opening between them. The inner faces of the seg ments and also the crank-lever may be covered with rubber or other suitable material to serve as a cushion, if so desired. The clock mechanism may be so set as to operate the cradle for any desired length of time. This mechanism is as well adapted for use with toy cradles for dolls as those of larger make, it being only necessary to vary the power of the clock mechanism.

While I have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.

I claim 1. In a swinging cradle, the combination with a frame, of a cradle pivoted to swing in said frame, a clock mechanism mounted on said frame, a crank-lever fixed on the end of the main spindle of said clock mechanism, a plate fixed upon said frame and segments adjustably secured to said plate and adapted to be engaged by said lever, whereby the cradle is operated, substantially as described.

2. In a swinging cradle, the combination with a frame, of a cradle pivoted to swing in said frame, a clock mechanism mounted on said frame, a crank-lever fixed on said frame, a plate secured to said frame, and horizontally-arranged segments adjustably mounted upon said plate, each of said segments having a hook end adapted to be engaged by said crank-lever, and a plane Working surface terminating in a curve upon which the end of the said lever is adapted to travel, substantially as described.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.

JOHN FLETCHER GRIMMETT. Witnesses:

A. BUCHAM, HARVEY GREENWOOD.
