'LLE N S. JIMMERSON, OF NEW ORK, N. Y. Letters Patent No. 85,670, dated JnWy 5, 1869.

'.l.hc Schedule referred to in these Letters Patent and making part of the same.

Ta all whom 'it mxy mmcm:

Be it known that I, ALLEN S. J IMMERSON, of the city, county, and State of New York, have invented a new and usefnl -lmprovem'ent in Pull-Irons for Horse- Gars, of Which the folloWflg is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, whichv Figure 1 represents a'plan of the platformend of a horse-car With pull-iron attached, and

Figure 2, aside view of the same.

V Similar letters of referenoe indicate corresponding parts.

In the ordinary hook or other attachment of the draughtpole to the platf0rm of horse-railroad oar's, there are many. disadvantages which do not attaoh to other vehicles, by reason, in part, of the upward character of the dranght tending to thiow the weight of the car on the 1earaxle, and often loaded condition of the overhangng rear platform, whic-h combine in lifiing the front of t e car, causing the latter to be thrown off the track. This, and other disadvantages, consequent upon such attachment of the pole, the here indesribed improvement obviates.

My invntion consists in an elevated arrangement of the pnlliron, as regards lino of dranght, relatively tothe platform of the car; also, in a certain braced {construction of the pull-iron, and of the bracket carr ing tlie'same.

'. Referring to the accompanying drawing, A represents the endplatform of a horse-raflroad car, in part,

and Which may here be referred'to as the front platform, the usual facilities for reversing the position of the pull' on tothe opposite end of the car, being, if desired, provided, by a siniilar construction of; parts,

for attachment of the-pnlliron to snob end, said pull iron being made removable for the pnrpose.

B is a vertical bracket or upright, firmly Secnred to the front end of the platform A, and braced by stays a in the.r ar.

'This bracket B is rnade with a top jaw, G, standing at a'considerable elevation above the platform, and

braced below by a roc], D, which also serves as a support for the foot-rest or lower portion b of the pnll-iron E, 'that clips said rod in a free or loose manner, so as to admit of the pull-iron swinging on or around the same, and of its removal, when taking out the pin 6, which establishes the joint of the upper portion, (1, of the pull-iron With the jaw O, said pull-iron extending in mmt,.aS at, 6, for attachment of the pole in any proper and in which will do away 'with the nsnal angnlar position 01 the pole, and serve to s11ppo1t the latter \vithontweight on the necks or coliars of the horses.

The upper portion of the pnll iron and lower sustaining and swinging part I) of the same, are connected by any desired nuniber of braces f.

manner, but at an elevation, relatively to the platform,

By this or 'other eqnivalent construction of the pull- IOD, and mode -of snppoiting or sustaining it, the following advantages are attnined:

First, in elevating the pnll-iron so that the dranght of or on the car is. considerably raised, and from the centre, as it were, in contradistinction to the nsnal upward draught, the weight of the car is not thrown npon the rear axle, or front of the car raised, which a crowded condition of the rea1platform tends to aggravate, and, by the overhanging position of said platform relatively to the rear axle, inclines to throwing the car off the track.

Secondly, the elevated position ofthe pnll-iron, and its 'crane-like construction, supports the polo from pressure or weight on the horses collars or necks,the lower free rest of the portion 11 relieving, too,.the jaw 0 of strain.

Thirdly, the whiffle-trees may be placed fnrther back than is practicable under the ordinary attachment of the polo, withont endangering tripping of the horses on the pole, by reison of the raised position of the whiflletres by this my improvement, thns enablingthe horses to work closer and more efiectively, and rendering it almost impossible for the driver to throw liis team.

Fourthly, increased facility foi stopping and starting the car, Whether running on a level or otherwise, and by stopping in shorter time or distances, redncing the liability to accidents.

Fifthly, increased firmness, by nieans of the braces, A both as regards the pulliron, and the means for car rying the same, as connected with the platform and support of the polo.

Whatis here claimed, and desired to be secured by
