CAR-MAGNET SUPPORT.-

Application filed January 25, 1906- Berisl 110,297,745.

Be. it known that I, \VILLIAM MILTON BROWN, of Johnstown, Cambria county, Pennsylvania, have invented a new and useful Improvement in Car-Magnet Supports, of which the following is a full, clear, and exact description, reference being had to the accompanying drawin s, forming part of this specification, iniwhic l- Figure 1 is a plan view showing my invention as applied to a pair of car-trucks with theparts in the positions which the; assume when thetrucks are passing aroum a curvein'g indicated in dotted lines. F ig; :2 is a of the magnet-support. Fig. 3 is'a side view of Fig. 2. Fig. 4-is a section on the line IV IV of Fig. 2, and Fig. 5 is a section on the line 1 VV-of-FigLQ; I 1

My invention has relat-ion to magnet-sup contact electric railways in which the circuitclo'sing magnets are carried by' the cars. In railways of, this class it is very desirable that the contact boxes or studs which are embedded in the track shall be arranged at the center of the track-that is, midway between the track-rails' at all points'as well on curves,

has been possible where single-truer cars carried on the trucks that the longitudinal center of the ma net-support will at all times be 'approxim'at y over the center of the not been heretofore possible, owing to the fact that the magnet-support must extend from one truck to the other, andprior tomy invention no method has been devised, in socould be connected to the trucks in such a m e the support t iatit will maintain prai.

far as I am aware, by which the support 1 manner as to maintain its proper relation to 1 the trackcenter m passing around curves. The ob ect of my invention is to acCQmpllSh this resu t in a simple manner and to so a i tic ly the same position on a double-t ue I car as if it were carried bet-ween the axles of a mum tract-ion typ the truckrames in various wa s. -The frame of a double-truck car. -In the form shown 60 these trucks are of the lwell-knou n maxie. 4 4designates't e lon itudinal frame, fromwhich are supported the depending circuit- Patented.

closing magnets 5. -This frame may be of 65 any suitab e construction capable, of --sustaming the weight of the magnets and of the .current-collectingshoe 6, which is'a'lso carfried by this frame. L' To carry the frame 4, qtrucks at a point between the bolsterjcenters I provide each of the with a transverse.supporting-bar 7 In the particular form of my invention illustrated the bar 7,issecured atits ends to side bars 8, wh ch extend over the'journal-boxes 9 of the axle'2 and are secured to the journal-box adjacent to the uides 10 and are thencecars ried downwar y and rear'wardly underneath the journal-boxes'l 1- of the axles 3 and are secured to the joumal-box adjacent to the guides '12 thereof. By this constructionv I provide a secure support for the overhan am]; but it will be obvious that such are or their e uivalent may be supported from 4 is pivotally'connected to t e central 01'- tion of each of the bars 7 b a pin or stu 13, as best shown in Fig. 4, t e frame 4 having oblong slots 14 to receive such pins'or studs, suitab e bearing-plates 15 being also interposed between said frame and bars-..

The broken line a a in Fig. l-indicatesthe longitudinal center of the car-body in passing around the track-curve'shown, the center of such curve being indicatedby the broken line 'b b. Thebroken line a c indicates the center of the magnet-supporting frame 4. By an examination of these center lines it will be noted that in passing around the i track-curve shown the center line of the magnet-support has shifted with respect to the center line of the car-body an amount equal to the distance between the lines a a and c s, but that the center line of the magnet-frame maintains a substantial coinci- With this object in view my invention coni deuce, with the center line of the track. slsts in the noyel constructlon, arrangement, I This coincidence is not of course an exact one; and comb nat on of parts, all substantiallyas l but the variation is so slight at any point in the length of the car-magnets as to be practi cally negligible. This position of the magnet-frame 1s assumed by reason of the pivot connections at 13, the elongated slots 14 taking care of the variatiou'in the longitudinal distance between the centers .of the bar 7' at different points of the curve and upon curves in any position which the frame can assume.

As above indicated, the support which carries the centers 13 may be constructed and arranged in various ways to correspond to diilerences in the construction of the various kinds of trucks which maybe employed in any case.

What I claim is-% 1. The combination with the trucks of a double-truck car, of a magnet-supporting frame extending, between the trucks and piv-.

otally connected thereto at points between the bolstercenters; said frame having extennets mounted on such extensions and also on sions beyondits' pivotal points, alnd magthe frame between the pivots, substantially as described.

2. The'combination with the trucks of a double-truck .car, of a magnet-supporting f-Jame extending between the trucks and pivoted thereto at points between the bolster centers, said supporting-frame being independent of the car-body; said frame having extensions beyond its pivotalpoints, and

magnets mounted on such extensions and also on the frame between the pivots substantially as described.

3. The combination with the trucks of'a. double-truck car. said trucks having overhanging or projecting supports extending between the trucks, of a magnet-supporting frame pivotally connected to the support of each truck; said frame having extensions beyond its pivotal points, and magnets mounted on such extensions and also entire frame between the pivots substantially as described. i e

4.' The combination with the trucks of a double-truck car, said trucks having supporting members extending between the trucks, of a magnet-supporting frame pivotallyconnected to each of said supporting members at points between the truck-bolsters and on the center lines of the trucks; said frame having extensions beyond its pivotal points; and

'magnets mounted on such extensions and also on the frame between the pivots, sub: stantially as described.

5. A car-truck having, side frame,- a supporting-b ar carried by the said frames, and a magnet-supporting frame pivotally connect-- ed to the said bar, at a point on the line of the truck and distant from the bolster center said frame having extensions beyond its pivotal points, and magnets mounted on such extensions and also on the'frame be tween the pivots, substantially as described.

6. The combination with the trucks of; a

double-trucl car, of a magnet-supporting frame extending between the trucks and hav-' ing a; pivotal and slotted connection therewith at points between the bolster centers; said frame having extensions beyond its pivotal points, and magnets mounted on such extensions and also on the frame between the pivots substantially as described. a

7. The combination with the trucks of a double-truck car, said trucks having; over hanging or projecting supports extending between the trucks and carried by the" caraxles independently of the trucleframe, of a magnetsupporting frame pivoted to the end bars of such supports, at points between the bolster centers and having magnet-carrying extensions beyond its pivotal points; substantially as described.

- In testimony whereof I have hereunto set my hand.
