CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 673,994, dated May 14, 1901.

Application filed March 22, 1901. Serial No. 52,413. (No modeL'l To (tZZ whom, it may concern;

Be it known that I, SAMUEL R. BAILEY, a citizen of the United States, residing at Amesbury, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Carriage-Springs, of which the following is a specification.

This invention relates to improvements on the patent granted to me for carriage-springs, No. 596,313, dated December 28, 1897, and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a side elevation of a carriage-spring, showing its ends connected by my improved device. Fig. 2 represents an enlarged bottom view of one of the ends of the spring and its connections to the upper spring. Fig. 3 represents a longitudinal section on the line 3 3, shown in Fig. 2. Fig. 4 represents a similar longitudinal section on the line 4 4, shown in Fig. 2. Fig. 5 represents a horizontal section on the line 5 5, shown in Fig. 4, and showing one end of the lower leaf of the carriage-spring. Fig. 6 represents a detail top plan view of one end of the said lower leaf. Fig. 7 represents a longitudinal section on the line 5 5 in Fig. 4, showing one end of the upper leaf of the carriage-spring; and Fig. 8 represents a detail top plan View of one end of the said upper leaf. 7

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In Fig. 1, A and B represent, respectively, the upper and lower leaves of an elliptic or leaf vehicle-spring, to which are respectively attached the additional leaf-sprin gs a a a and b b b, as is usual in this kind of carriagesprings. To each end of the upper springA is secured a metal socket 0, preferably by means of a rivet D, as shown in Fig. 4. This socket O is provided with circular closed end pieces 0' 0, made integral with said socket, to prevent a lateral motion of the free spring B relative to the fixed spring A in a manner like that shown and described in my aforesaid patent. The lower portion of the socket C is provided with an inwardly-projecting lip C, which serves the purpose of ,holding the ends of the upper and lower springs together and preventing their getting apart by the jolting of the carriage or otherwise in a' manner as fully shown and described in my aforesaid Letters Patent. In a device of this kind it is desirable that the ends of the lower free spring B should be lubricated where it enters the socket C, so as to prevent wear, rusting, and squeaking, and for this purpose I make in the middle portion of each end of said free spring B a recess or cut-away portion B, and opposite to it I make on the internal portion of the socket C a corresponding recess or pocket 0 in which is placed a cushion or pad E, preferably made of felt or suitable textile or fibrous material, which is preferably soaked in grease or oil or otherwise charged with a suitable lubricant. For the purpose of still further causing the ends of the lower free spring B to be lubricated I make in each end of the fixed spring A a similar recess A, and opposite to it I make on the internal portion of the socket O a corresponding pocket or recess 0, in which is placed a pad or cushion F, soaked in grease or otherwise charged with a suitable lubricant, which will serve, as it were, as a feeder for keeping the lower pad or cushion E properly lubricated for the purpose above stated. The said pads or cushions being charged with the lubricant will cause the latter to enter between the endsof the free spring B and the internal portions of the sockets 0, thus accomplishing the object to be attained-namely, preventing wear, rusting, and squeaking between the bearing ends of said spring B and the sockets O O, in which the ends of said spring are contained. I may use such pads at the ends of both upper and lower springs, or either of them, as may be most desirable in practice. In case such pads or cushions should become dry they may readily be recharged with a lubricantfrom time to time as may be found needful.

What I wish to secure by Letters Patent and claim is 1. The herein-described carriage-spring, consisting of two members, to the ends of one of which are secured socket-pieces, having closed ends and the ends of the other member of which are freely disposed in said socketpieces, and confined against lateral displacement by the closed ends thereof, the ends of said free and fixed springs, or either of them having a recess adapted to receive a pad or cushion charged with a lubricant substantially as and for the purpose set forth.

2. The herein-described carriage-spring, consisting of two members to the ends of which are seen red socket-pieces, having closed ends, and the ends of the other member of which are freely disposed in said socketpieces, and confined against lateral displacement by the closed ends thereof, the ends of said free and fixed springs, or either of them having each a recess corresponding toan internal recess in the interior end portion of the socket and a pad or cushion charged with a lubricant arranged between each end of said spring or springs and the interior of the socket substantially as and for the purpose set forth.

3. The herein -described carriage-spriug, consisting of two members, one of said members being secured to sockets and the ends of the other member freely disposed in said SAMUEL R. BAILEY.
