SPECIFICATION formingpart of Letters Patent No. 299,735, dated June 3, 1884.
Application filed May 24, 1883. Renewed January 22, 1884. (No model.)
To aZZ whom it may concern.-
Be it known that I, GHARLEsE. CANDEE, of the city, county, and State of New York, have invented a new and Improved Running- Gear for Railway-Oars, of which the following is a full, clear, and exact description.
The object of my invention is to facilitate the travel of railway-cars upon curves, so that I they can be carried around short curves safely and without excessive wear upon the wheels and rails.
The invention consists in car-trucks provided with oscillating boxes combined with certain mechanism arranged to be moved automatically by the swing of the car, so as to escillate or swing the axles and thereby retain the axles in a position approximating the radii of the curves, all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l'is a side elevation, and Fig. 2 is an end elevation, of a car-truck of myimproved construction, the bolster and a portion of the car being shown in Fig. 2. Fig. 3 is a central longitudinal section, and Fig. 4. a central transverse section, of the truck. Fig. 5 is a longitudinal section in larger size at one side of the truck. Fig. 6 is a plan view of the truck, the bolster and springs being omitted. Fig. 7 is a section of one of the boxes on the line a a, Fig. 5; and Fig. Sis a plan view of the sup-' portingrate used with the oiling devices.
. The truck-frame consists of upper longitudinal side bars, a, and lower side bars, I), connected at their ends by pedestals-0 a, between which are the boxes A A. At their mid-length the upper and lower bars, a b, are connected by pedestals (1, and e e are cross-bars carrying supports f, upon-which are the elliptical springs g g, (shown in Figs. .2 and 4,) that support the bolster h. turn supported by springs 1', (shown in Figs. 1, 2, and 3,) that rest upon suitable supports upon lower cross-bars, 7c, that connect the lower side bars, b. The frame is also suitably braced, as shown in the plan view Fig. 6. The boxes A are connected to the lower side bars, b, by jointed links Z, so that the boxes The cross-bars e are in are capable of movement in a direction longitudinal of the truck, space being left between the pedestals c and the boxes to allow of such movement. At each side of the truck are cylinders B B, which are supported in bearings formed in the pedestals d, and these cylinders are formed internally with right and left hand screw-threads at the opposite ends.
on m are shafts extending into cylinders B, through packing-glands n, and formed within the cylinders with screw-threads for engagement therewith. The outer ends of th ese sh aft-s, extending from'the opposite ends of the cylinders, are jointed to bosses or arms 0, formed or attached upon the sides of the boxes A.
At the center of the truck, andsupported lengthwise of the same in boxes 12, is a crank or rock shaft, g, from the crank of which'rods or links r r extend to the opposite sides of the truck, where they are connected to rods 8 s, that are bolted to the cylinders B. At its outerend the shaft q is fitted with an adjustable crank-arm, if, from which rods u a pass, as shown in Fig. 2, and are connected to castings 2;, attached upon the car-sills. The attachment of the rods a to the castings 'u is by means of bolts and nuts, which are jointed to allow of change of movement, and also to permit of endwise adjustment of the rods.
The bosses or arms 0, to which the screw-rods m are connected, pass through apertures in the pedestals 0, the apertures in the pedestals being of sufficient size to allow of the vertical movement of the boxes and truck-frame, and at the outer sides of the boxes studs 0 project through the end pedestals, so as to prevent any turning movement of the boxes. By this construction and arrangement on a straight track,when the two trucks of one car are in line and the axles at right angles to the track, there will be no movement of the cylinders B in their bearings in either direction; but as soon as the truck passes upon a curve, thereby changing its position in relation to the other truck of the same car, the side or lateral swing of the car will cause movement of the cylinders through the movement of the bars a, crank-shaft q, and connecting-rods r, the cylinders" being thereby given a partial rotation toward the inside of the curve, and the screws of the cylinders, acting upon the screwrods m, will cause the endwise movement of the said rods, those at the outer side of the curve being moved outward toward the end.of the truck, and those at the inside of the curve being drawn inward or together, and the boxes will be thereby caused to swing so as to oscillate the axles, bringing both axles to a position approximating the radii of the curve, as illustrated in Fig. 6. By this oscillating or swinging of the axles the wheels will pass readily over the curved track without binding, and the trucks will thereby be carried around a short curve with safety and without undue wear upon the rails and wheels. By adjustment of arm t on shaft q the extent of movement is varied.
The oiling devices in the box A are shown in Figs. 5 and 7.
a is a grate made in the form of a segment of a cylinder, and supported beneath the axles G by means of springs Z) beneath side lugs up on the grate that are guided by rods 0. Upon the grate is fibrous material, with which the journal ofthe axle moves in contact, and the oil, being placed in the lower part of the box, is drawn up by the fibrous material through the apertures in the grate by capillary attraction, and the journal is thus constantly supplied. The box is formed with a partition, (1, in its front portion ,that separates the axle-box prop er from the outer end of the box, so as to exclude dust and dirt from the bearings. The
outer end of the box is provided with a removable cover, so that oil may be supplied, and the oil,passing through an aperture in the lower part of the partition, enters the space beneath the grate a.
The box is also formed at its inner side with a packing-box, 0, around the axle, and in this manner dust is thoroughly excluded from the interior of the box.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In car-trucks, the combination of the axles C, the oscillating boxes A, the screwcylinders B,the connccting-rodsm 1', and the crank-shaft q, fitted for movement by the swing of the car, substantially as described, for operation as set forth.
2. In car-trucks, the combination of the box A, the jointed links I, the screw-rods m, and screw-cylinders B, substantially as shown and described. 1
3. In car-trucks, the combination of the rods to a, connected to the car, the crank-shaft q, the connecting-rods r, the screw-cylinders B, the screw-rodsm, and the oscillatingboxes A, substantially as described, for operation as set forth.
4. The adjustable crank-arm 15, combined with rock-shaft q, oscillating boxes A, and connections between the shaft and boxes, substantially as described.
5. The combination, in a car-truck, of the apertured pedestals c and boxes A, provided with arms 0 0, substantially as shown and described.-
6. The combination, in a car-truck, of the screw-cylinders 13 and pedestals d, formed with bearings to receive the cylinders, substantially as described. 7 7
