To all wh m i m y concern: members 2-.- The brackets 5 are formed Be it known that I, Monrrz WEINSTEIN, a with perforations through which passes a subjectof the King of Roumania, residing at shaft 6 having angular extensions 7 outside the city of St. Louis, State of Missouri, United States of America, have invented a formed with stub shafts 8 upon which are new and useful Improvement inBaby-Bugmounted the front wheels 4. gies and the Like, of which the following is a I 9 indicates a cross-bar extending between specification, reference being bad to the acthe front supporting frame members 2. companying drawings, forming part of this I 10 indicates a sleeve orhub on the shaft 6 specification, in which j and secured thereon by set screws 11.

ing the several positions of the front Wheels Fig. 3 is an enlarged detail view of one of the side brackets which support the shaft carrying the front wheels; Fig. 4 is an enlarged I detail view, looking from the inside, of the i bracket shown in Fig. 3, showing the said spring 17, the other end of said spring being shaft in cross section and the spiral spring i attached to said cross-bar 9. The lower end co-operating therewith; Fig. 5 is a detail 1 of said lever 15 carries a small wheel 18,, the front view of the parts shown in Figs. 3 and periphery of which is normally slightly above 4; Fig. 6 is an enlarged detail view of the i the tread of the carriage, as shown in Fig. 1. locking and tripping lever and its co-operat- The tips of the forward ends of the suping parts; and Fig. 7 is a front view of the porting frame members 2 are bent at right parts shown in Fig. 6. angles, as at 19, and have attached thereto This invention relates to a certain new and one end of a spiral spring 20, see Fig. 4. useful improvement in baby buggies and the The opposite end of said spiral spring like, the object being to provide means whereis fastened to a sleeve 21, which sleeve is by, when the buggy is rolled or passes absecured on the shaft 6 by means of a pin 22. ruptly from a higher to a lower plane, such The sleeve 21 is preferably formed with a plurality of alining perforations and on the withdrawal of said pin 22 is free to rotate on said shaft 6, whereby the tension of said spring 20 may be varied or adjusted, for purposes hereinafter described.

The tendency of the s rings 20, one of between the bracket members 13 is alever co-operate with said notched disk 12. To the upper end of said lever is secured a coiled is prevented from tilting forwardly.

With this object in view, the invention consists in novel means whereby, when the buggy isrolled or passes abruptly from a higher to a lower plane, a frame carrying the front wheels is automatically operated, the l which is on each side of t e buggy, is at all front wheels lowered, and the body of the times to rotate or rock the shaft 6 and extenbuggy prevented from tilting forwardly, sions 7 and thereby throw the wheels 4 backmeans being also provided to lock the wheels wardly and thus elevate, due to the conin normal or elevated position; the invention 1 struction of the rocking frame 6, the front part of the body of the buggy, as shown in dotted lines in Fig. 2. The shaft 6 and wheels 4 are, however, locked or held in normal or elevated position, as shown in Fig. 1, by means of the rojection 16 on lever 15 engaging the note 12 on the disk 12, the projection 16 being held to its engagement with said disk by means of the coiled s ring 17, see particularly Fi s. 1 and 6. ow, should the buggy be rol ed or pass abruptly from a higher to a lower plane, as from 3.

tion, arrangement, and combination of the 1 several parts, all as will hereinafter be described and afterward pointed out in the claims.

Referring to the accompanying drawings, 1 indicates the body of the buggy; 2 the supporting frame for the body of the buggy; 3 the rear wheels; and 4 the front wheels.

5 indicates bracket extensions secured to the brackets 5. The shaft extensions 7 arev 15 provided with a projection 16 adapted to the buggy and carried infant is more evenly body of the buggy, but, by means of a guard plate 23 and stops 24, see Fig. 3, regulate the backward throw of the extensions 7 and keep said extensions in an obliquel forward cs1- tion, so that the tendency of t e front W eels is to resume their normal or elevated position when the front and back wheels are again on the same plane and the weight of the body of distributed. The tension of the springs 20 is normally adjusted,-by means of the sleeves 21 and pins 22, to slightly over-balance the weight of the carried infant, so that when the front and back wheels are again onthe same plane, the weight of the buggy and carried infant will overcome the tens1on of springs 20 and force the wheels 4 back to normal position, when they are again locked by pro'ection 16 on lever 15 engaging notch 12 on 'sk 12. Should, however, the front wheels, on the buggy reaching a level surface, not readily resume their normal position, only a slight pressure of the hand is required to accomplish this result.

In the backward rotation of the shaft 6 in throwing the front wheels rearwardly and downwardly under the body'of the buggy, the projection 16 on lever 15 will drag over the notches 12 on the disk 12, as said disk 12 rotates with said shaft 6, and thus said notches 12 serve to retard or cushion the backward throw of the wheels and prevent jarring. The length of the extensions 7 is regulated according to the particular construction of buggy or wagon involved. For baby buggies, in large cities, the extensions 7 would be made of slightly greater length than the height of the curbing, as is obvious. Due to the novel construction of the frame 6, the front wheels are projected forwardly, thus giving the buggy a broader base than is usual in these constructions and thus lessening the liability of the buggy overturning.

In rolling the buggy from a lower to a higher plane, as the carriage is usually tilted upwardly in front to raise the front wheels, the lever 15 is not generally tri ped; but should the lever 15 be tripped by t e curbing or other projection, the effect would only be a further tilting upwardly of the front of the buggy; but in such case, there is practically no danger of the infant falling from the buggy, as both the back of the carriage and the person rolling the carriage are present to prevent the infant from falling out of the rear of the carriage. The main danger generally in these constructions is the liability of the infant falling out the front of the carriage on passing from a higher to a lower plane, and this danger is obviated by my invention and without necessitatin the buggy being bodily lifted on passing om a higher to a lower plane or wlthdut requiring the person rolling the buggy coming from the rear to the front of the buggy. Should the front wheels be thrown downwardly and backwardl by the accidental tripping of the lever 15 cm an cause, there would be no danger of the infiint falling from the buggy, as the said wheels would be swung backwardly and downwardly slowly, the buggy would be tilted backwardly-mot forwardly where the danger of the infant falling from the buggy is presentand the person rolling the carriage, being in the rear of the carriage, could easily prevent the infant falling from the buggy, as heretofore described.

While I have more particularly herein described my improvement as applied to a baby buggy, it is obvious that there are many other constructions to which my improvement could equally as well be applied.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
