LIFE-SAVING MECHANISM FOR TRAIVIWAYS.

SPECIFICATION forming part of Letters Patent N 0. 695,340, dated March 11, 1902..

Application filedDecember 27, 1901. Serial No, 87,453. (No model.)

To CLZZ whom it may concern:

Be it known that we, WILLIAM PHILIPSON, THOMAS WHIT LE Horwoon PHILIPSON, and PERCY OLARKsoN PHILIPsoN, engineers and 5 machinists, subjects of the King of Great Britaimof Holland Street Iron Works,Astley- Bridge, Bolt-011, in the county of Lancaster, England, have invented certain new and useful Improvements in Life-Saving Mechanism for Tramways, of which the following is a specification.

This invention relates to life-saving mechanism for tramways; and it consists of side and intermediate longitudinal springs disposed on I a bar mounted on centers located in bearings secured to the under side of the tram-car, the end of each side and intermediate longitudinal spring being fitted with a sole of either india-rubber or other suitable material or substance. This apparatus is connected with a brake of shoe form carried in close proximity to the wheels of a tram-car and held in suspension by adjustable rods, chains, and weights supported from the tram-car and kept from contact with the wheels'of the tram-car when the side and intermediate longitudinal springs are out of action.

Figure 1 is a longitudinal elevation showing our invention applied to a tramcar; Fig. 2,

a plan of Fig. 1; Fig. 3, a front view of hanging gate disposed at each end of a tram-car; Fig. 4:, an enlarged side elevation of tripmotion, showing the same holding the lifesaving mechanism out of action, as indicated on left-hand side of Fig. 1; Fig. 5, an end view of right-hand side of Fig; 4; Fig. 6, an enlarged side elevation of trip-motion releasing the side and intermediate longitudinal springs in case of the hanging gate being ac- 0 tuated by any obstruction met with on the tramway-track, and Fig. 7 an enlarged side view of brake apparatus and its connection with the life-saving apparatus.

A represents so much of the outline of a tram-caras is necessary to illustrate our said invention; B, tram-car wheels; O, axles; D, platform at each end of tram-car; E, bottom framework of tram-car, and G the tramwayrails.

In all the figures the same letters and unmerals are employed to indicate corresponding parts.

To the transverse boards F, disposed on the under side of the tram-car A, are secured by bolts or coach-screws the side frames or fixings H, which are also held, supported, and adjusted by the screwed rods I and nuts J, attached to the cross-bars K, secured in any convenient manner to the under side of the bottom framework E of the tram-car A. To the side frames or fixings H are pivoted the side and intermediate longitudinal springs L bythe pins or centers M. The side and inter mediate longitudinal springs L are secured to the transverse bar N, fitted with the clips O, pivoted to the side frames or fixings H by the pins or centers M. The front end of each side and intermediate longitudinal spring L is provided or fitted with the sole P, consisting of either india-rubber, leather, gutta- 7o percha, and the like. Above the side and intermediate longitudinal springs L is disposed the canvas bag, cover, or receptacle Q, composed of netting and the like and so ar ranged as to catch or contain any obstacle that may be met with or run down when the tram-car A is in motion. The upper end of the canvas bag, cover, or receptacle Q: is attached to the center R, carried by the side frames or fixings H. The transverse bar N is provided with the upright S, to which is pivoted the lever T by the pin or center U. The lever T is provided with the notch a, fitting on the pin or center b, mounted in the fixing V, secured to the transverse board F by the screws 0. The lever T extends beyond the notch a and is provided with the adjustable weight d, secured thereto by the setscrew 6, as shown in Fig. 4. On thepin or center I) are supported the levers f and c, 0 connected at their upper ends by the pin or center h, on which is mounted the rod i. The other end of the rod i is coupled to the lever j, mounted on the shaft or center 70. The shaft or center 76 is carried from the side 5 frames or fixings II by the levers Z, mounted on the centers m. On the shaft or center it are loosely mounted and hung separately the series of Wire, metallic, or other bars WV in such a manner as to allow of backward and I00 vertical movements, thereby enabling the bottom ends of the said wire, metallic, or other bars W to ride closer to the face of the road than hitherto without interfering with the action of the same when the tram-car is making a backward movement or in case of oscillation of the tram-car or when coming into contact with any obstruction met with on the track or road when the said car is making a backward movement. or center it is fitted with the arm or lever 72, carrying the transverse rod 0, located behind the wire, metallic, or other bars W, by which the latter are held in a vertical position. The said wire, metallic, or other bars W are distanced from each other by the ferrules 1), disposed on the shaft or center it. Under each step X, leading to and from the tram-car platform D, is disposed the shaft or center r, mounted in the bearings or fixings 25, secured to the step X in any convenient manner. On the shaft or center r are loosely mounted and hung separately the series of wire, metallic, or other bars Y. Each end of the shaft or center r is fitted with the arm or lever u, carrying the transverse rod 4;, located behind the wire, metallic, or other bars'Y, by which the latter are held in a vertical position. The said wire, metallic, or other bars Y are distanced from each other by the ferrules w, disposed on the shaft or center 1. The transverse rod 12 and the transverse rod 0 are connected together by the chain a: to allow of the same actuating the levers n andj and the rod '6, connected to the lever f, mounted on the pin or center I), as shown in Figs. 1 and 4, by

which action the trip-lever y, attached to the lever f, will release the notch on of the lever T from the center I), as shown in Fig. 6, by which action the side and intermediate longitudinal springs L will be liberated and fall down to the position shown on right-hand side of Fig. 1, thus enabling the same to catch or contain any obstacle that may be met with or run down when the tram-carAis in motion.

To insure of the life-saving apparatus above set forth, it is absolutely necessary that the tram-carshould be stopped with the least possible delay, which we effect by connecting the same to the brake operating in conjunction with the tram-car wheels B. To the under side of the bottom framework E of the tramcar A are attached on each side in line with the tram-car wheels B the fixings A, secured thereto by the clips B, as shown in Fig. 7. The fixings A are provided with the chainpulleys O, mounted on the pins or centers D, secured to the fixings A in any convenient manner. Over the chain-pulleys O are located the chains E, secured to the eyebolts F and-G on the shoes H and balanceweight 1, respectively. The shoes H are connected together by the bar J and bolts K. The shoes H are held out of action when the brake is not required by means of the suspended balance-weight I, connected thereto by means of the chains E. The bar J is pro- Each end of the shaft.

vided with the weights L, located inside the suspended balance-weight I, for balancing purposes to insure of the shoes 11 assuming their proper position clear of the tram-car wheels B when the brake is out of action. The shoes H on each side of the tram-car A are connected together in pairs by the transverse rods M. On the transverse rods M are located the longitudinal adjustable rods N, connected to the levers 0, attached to the shaft P, mounted in the fixings Q, secured to the transverse boards F. On the shaft P is mounted the lever B, to which is connected the coupling-rod S by the pin or center T, the other end of the coupling-rod S being connected to the hand-lever U, pivoted to the fixing Y, secured to the platform D, as shown in Figs. 1 and 2. The coupling-rod S is provided with the projection W, which operates in conjunction with the lever X, carried from the transverse bar N, supporting the side and intermediate longitudinal springs L, by which the tram-car driver or attendant can reset the life-saving mechanism herein set forth by means of the hand-lever U.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is The combination of life-saving mechanism for tramways consisting of the side and intermediate longitudinal springs Lwith or without the canvas bag, cover, or receptacle Q-provided at their outer ends with the soles P; the inner ends being secured to the transverse bar N fitted with the clips 0 pivoted to the side frames or fixings H by the pins or centers M; the transverse bar N being provided with the upright S to which is pivoted the lever T having the notch a fitting on the pin or center I) mounted in the fixing V carrying the leversfand g and the trip-lever 11 the upper ends of the levers f and 9 being connected to the rod t' attached to the leverj mounted on the shaft or center carrying the loosely-mounted and separately-hung series of wire, metallic, or other bars W suspended by the levers Z from the outer endsof the side frames or fixings H; the shaft or center 70 having the levers 'It carrying the transverse rod 0 connected by the chain 00 to the rod 4) located behind the wire, metallic, or other bars Y suspended under the steps X: the hand-lever U being coupled to the rod S connecting with the lever B mounted on the shaft or center P; the rod S having the projection W to operate in conjunction with the lever X carried from the transverse bar Nsupporting the side and intermediate longitudinal springs L for resetting the latter: the shaft or center P having the levers 0 connected to the longitudinal adjustable rods N mounted on and connected with the transverse rods M attached to the shoes H; the latter being connected together by the bar J on which are mounted the weights L located inside the balance-weight I, the latter being attached to the shoes H I In testimony whereof we have hereunto set 10 by means of the chains E passing over the our hands in presence of two subscribing Witchain-pulleys O mounted on the pins or cennesses.
