Be it known that I, JONATHAH-CHILDS, of West Troy, State of New York, have invented anew and useful instrument for the repair of any axle of a carriage that may be sprung or bent so as to affect injuriously the" movements of-any wheel revolving on the axle, either as to its tracking pr0perly,-or its proper alignment with the other'v'rhee'ls of the carriage. I. call it a Carriage-Axle Adjuster, and'l declare this specification, withthe drawing formingrpart thereoi, to be a full and accurate-description of iny invention. l 7

Whenever an axle-tree becomes 'bent, in order to straighten it by the usual method,it is necessary to detach how the carriage and then separate the iron from its wooden portion, in order to submit it to the necessary treatment to bring it to its proper. shape without injury and defac'ement of its wood and paint. This is atedious and expensive operation, which it is the object of my invention to avoid. The drawing represeiits my adjuster applied to an axle-tree. v

' Agrepresents the axle-tree; B its wooden, 0 its iron bar, connected together by the clips D D. E E are the journals. Theadjuster consists oi a square bar of iron or steel, G, of such length'as lnay be found most convenient for'pratical use]. One end, H,Vis turned up to form a small spur to keep the body of the bar from touching the axle, the other end is pierced with an orifice to pass the stem of the adjusting screw. This consists ofascrew-stem, s termin ated by a loop, L, fitted to be passed over and upon either of the journals. The-screw isjoperated hyvnut-levei'd J and K, one above, the other below the bar'G. F is a fulcrum block spanning bar G- by a groove in its lower "surface, so as to slide along the bar, and its upper surface is slightly rounded. M N are two movable sc'rew clamps of any convenient form for service with the instrument.

The mode of operating with this instrument is thus: In the drawing, the journal E is represented as bent upwards, so as to prevent the proper tracking of the wheel, and it becomes necessary to bend it down from its shoulder at e. To do this the fulcrum block F is placed below the axle, as near es as is convenient, the bar G brought up'to it froin below, the loop L of the adjusting screw slipped over the end of the journal, and the bar G secured to the axle by the clamps M, one being near'the spur l1 and the other over the block F. The screw-nut J is slacked, and"- K turned upwards, drawing the loop L, with the end of the journal, downwards, until it has its proper range with the 'body of the axle. If the journal were bent downwards then the operation. of the screw-nuts should be reversed, K being slucked and J turned downwards, forcing the end offih e journal upwards. If the'axle be bent at a point between the journals, the block F is to be placed atthe point of the bend nearest the centre of the axle, and the bar Gr be adjusted so as to bring loop L up to the shoulder e, and then the screws J andK operated as described, to bend the airle upward or downward, as the nature of the bend should require. If' the axle should be bent in a horizontal direction it would only be necessary; to place the bar G, with its apparatusn in a horizontal position, and operate it as described. i I

'll e advantages of this apparatus consist, first, in its being applicable to its work without the detaching of the axle-tree from the carriage, and consequently in avoiding. the mar-ring of its point and injury to the wood; scico'nd, in not wearing the screws of the clips by unscrewing and screwing them up; third, the great saving (if tiinennzl egrpense in doing the work. l

'What claim as mydni'ention, and desire toseeure by Letters Patent,- isi A carriage axle-adjusting instrument formed of the bar G, in combination with the block F, the adjusting we? S, with its nut-levers J and K, and the clamps M and N, substantially in the manner set forth in this specification. I i

-. JONATHAN CHILDS.
