, 3'Claiins (01'. -109) This invention relates to mechanisms and devices for imparting a reciprocative or. a rocking movement to baby cribs, and the like.
One of the principal objects of the present invention is to provide an electrical unit, o1 simple and economical by construction, for, effecting adelayed reciprocati-ve movement of a crib, or the like, so that there-is a; period ot-rest at the end of each movement before-the crib is started on its return movement of each cycle.
Another, and important, object of the present invention is to provide a. mechanismior effecting reciprocative movement of a crib, or, the like, which may easily be connected to cribs-bidirierent widths or lengths, depending on whether the movement is intended to be lengthwise of the crib, or transversely.
A further object of the present invention is to provide a mechanism for the purpose mentioned in which the mechanism is housed to prevent injury to children, or others. f
A still further objectof this invention is to provide a mechanism for the purpose mentioned in which the tracks, motor, sprocket wheels, chain and control switch are. of conventional types which can be purchasedon the open market at relatively low prices.
Other objects and advantages of the invention will appear from the following specification and reference to the accompanying drawings showing one embodiment of the present invention, in which:
Fig. 1 is a sectional view, in side elevation, through a crib and the mechanism of the present invention, taken partially on the line Il of Fig. 2.
Fig. 2 is a section, in end elevation, taken partially on the line 2-2 of Fig. 1.
Fig. 3 is a perspective view of the front end of the mechanism, with the housing removed therefrom.
Fig. 4 is a perspective view of the mechanism with the housing in position over the mechanism.
Referring to the drawings in which like numerals designate like parts in the several views, the crib I0 is provided with grooved rollers l2 which are adapted to roll on a pair of tracks H, which have narrow treads l6 upon which the rollers [2 travel. Pairs of transverse, and overlapping bars 18, having registering longitudinal slots 20 are secured to the inner edges of the tracks, by suitable means, such as rivets 22, so that they will be rigid with the tracks.
The electrically operated mechanism, or unit 24 includes a motor 26, having a drive sprocket wheel 28,-.mounted' on one end of a base 36, and adriven' sprocket wheel 32 mountedin a bear- 'ing ;-34.-.on theopposite end oi. the base with asprocket chain 36 operatively connecting the two sprocket wheels 28 and 32. A connecting-bar 36,havingtherein a, slot '40, is pivoted at one end to a-linkpivot pin 420i the chain 34. This pin 42- projects. outwardly. from the chain, and the bar 38 has abos's 44 on its inner side to space the; bar awayfrom contact withthe chain. The slotted portion of thebar-38 is slidably connected to a transverse. pin -46 which. projects from :one side of a cross rail 48, carried by the crib .10, into .thelslot fll. If desired, a block of; rubber 4!, or
other suitable resilient element, may be inserted in, the. outertend-ot slot-.46 to cushion the contact of :the'end of the, slot with pivot pin. 46.
The base '36; is. secured to thebars: I Bby means of bolts "50 which project through registering belt holesin the base and through the slots 26 of .therpairs of ,bars. When the, nuts, 52. are loosened the. tracks 14 may be adjusted toward or from. eachother, and, when tightened, these nuts clamp the base 39] and the tracks rigidly together inadjusted position. In this manner the tracks [4 maybespaced, as ,desired, for cribs of different widths, so that the bar 38 will be in proper position for connecting to the pin 46 on rail 48.
A housing '54, having a longitudinal slot 56 along one edge of its top portion, is secured to the base 36 by means of screws, or bolts 58, which project through cars 66 carried by the lower edges of the housing. The height of the housing is somewhat less than that of the wheels 26 and 32, to permit the chain 36 and connecting bar 38 to project through and move freely in the slot 56. The housing may be made of enameled metal, or other suitable material, and it not only protects children, and others, from injury by the motor and other moving parts, but imparts a finished and attractive appearance to the unit. A shallow pan 62 may be placed under the chain 36 to catch any oil that may drip therefrom.
An extension electric cord 64 can be used to connect the motor to a wall socket 66, and a switch 68 connected in the electrical circuit to start and stop the motor 26 may be placed on the crib or, if desired, in a remote location, such,
for example, as in a difierent room or on a different floor from the one occupied by the crib Hi.
In Fig. l the bar 38 is shown in full lines just as it has completed movement of the cribylfl to the right, with the chain 36 traveling in the direction of the curved arrow. At this point the I r crib will remain at rest on the tracks [4 until the pin 42 travels around the outer rim of the wheel 32, the bar 38, in the meantime, sliding outwardly on the pin 46, this being permitted by slot 40. After pin 42 passes the vertical center line of the pin 46, the bar 38 will be drawn inwardly by the travel of the chain until the upper end of slot 40 reaches pin 46, at which time the crib [0 will be drawn totheleituntil it reaches the position shown in dotted =lines. The bar 38 will thenbe in the position also shown in dotted lines. With the chain 36 traveling in. the same direction indicated, the connecting bar 38, as shown in dotted lines, will adjust itself, on the pin 46 and draw the crib l0 backto the This delayed recip-' rocative movement will continue as long. as themotor runs, and it may be instantly stopped by si-tion shown in full lines.
actuating switch 68.
The entire unit may be easily applied to any crib by providing therail =48 withpin 46* tor connectio'nin the'slot 40 of connecting bar .38. Also, 'the'distance of travel of crib. 10 on tracks l4 may be increased'or reduced by lengthening or shortening the base 30 0i the'rocking unit.
' Changes in the details of constructionma'y. be
made in my improved mechanism without departing from the spiri-tandscope of my invention. For example; it is obvious that pulleys "and a belt, 'althougnnot' so"efiicient, could-be substituted for the sprocket'wheels'and chain. -'Also other detail devices for permitting lost motion between the'connecting 'bar'and the crib could be substituted'for the'slot 40. 'Therefore,
it should beunderstood that'the specific embodiment of myinventionshowniin the drawings,
and described 'in the specification, i'sintende'd to vbe illustrativejohly, and not restrictive thereto.
