HERMANN LEMP, OF LYNIQ, ii'ii- ELEUETRM) TEMP SSAUHD'SE FTS, 1* A CUitPUl-Eifiiiii 0F 15i" Application filed May 23, 1905.. Selim ii'o. $561,855.


This invention reietes to eutooiobii as hav ing steering-gear operated by a hand-wheel; end its object is to provide a simple and effective hydrziuiie checking device 1' the same to prevent the transmission of steering- Wi'i Ll strains to the 1] ends of the operator.

"i so present invention to steering ear in which there o poweomuitipiying device between the iieiid wheei Midi-i153 steer-- 'iig-wheeis end in which the iiydi'euiic cjiieoio device independent of the POWQf-ilillitiplying device. Such e scheme is broediy claimed in mypending:i1') ')iioa-tioi1,Serial No 188,848. in another application 261,144, I have shovm such 2:- sys i inflamed valve for the checking C said voive being mo'vei'i lengthwise my Q Hi passing up through the steering-post to on auxiliary hand wheel. in. the pi'esont oppiication 1 use this balanced valve and operate it by similar means; but the mechanism for transmitting power from the steering-post to the stceringwhoeis and the she king device for controlling the movement of the steeling-post are speeiiiooliy memos and constitute the novelty herein. As in the 1sst-mentioned application, the invention is especieiiy applicable to higitspeed cars, in which it is of 4 the utmost importenee timttiiere sholi be no play or lost motion in the steering-geeiiv The enguior movements of the stem post transmitted by chains and seotoioshe ves to a IOGiZ-Shitft which has one or more arms pivoteily connected with a doubleended piston, or two connected pistons working in two cyi'inders filled with liq uid and connected by e by-pess, which is controlled by the aforesaid balanced vaive. Provision is made for taking up all slack, so that o rigidly-Working of connections is produced. The rocksheft has :in arm suitably connected with the steeringwvhecis, so that the angular movement of the steering-post will be communicated "hereto.

In the accompanying drawings, Figure l is Tiie steoi'ingpost at its upper c1 .1 21.11:: ,Trototebie in s cost i\ we item. the -i inverted i'eet device can. be en. suite ioiiiie.

The shaft carries on one 20, which is suitably connected with the steeiiins;-wli.eeis,

so that they can be eontroiled by t e steco ing-post.'

The hydraulic checking device comprises the CY iillt'ifii 5, which has a iongitudiiioislot 21 in one or both sides for 8, portion its 5 chest are two circumferential grooves 31, one

length, so that the only completely cylindrical portions are-st the ends ofthe cylinder 5. In each of those portions is, a piston 22,

rflvitlcd with cupped leather packing 23. lhe pistons are l'lgidly connected, as by means of the sleeve 24, in which is a crosshcad 25', forming a bearing for the wrist-pin 26, whose ends project through the slots 21, so that-it can be connected, preferably, by meanso'f one or more pivoted connecting rods or links 27, with an arm or arms 28, rigidly secured to the rock-shaft 17 in a lane transverse. to the axis of the cylinder; rem.

this-construction it follows that the coins oo'poi'ntdnits length thebyass is'provided with a controlling-velve. .;hl5 is preferably located in a valve-chest 30, secured to the cylinder, said valve-chest being preferably at cylinder with its axis in line with that of the steering-pest.- In the inside of the valveabove-themher and resectively connected wi-th' the adjscentends 0 the by -pass, .The yalve has as lindrical tubular body 32, provided '-with ends 33 of e ual area. The valve-chest is filled with liq md, which passes freely through the tubular oody of the valve, so, that the pressure'onits heads I:- balanced. The lower groove 31o tween saidhcacls, While the upper groovcis normally'closed b the upper head. When.

5 the-valve is raise the upper groove is 1111- covered so that the two grooves communie cats and'the liquid can pass freely from one end of tlfs cylinder to the, other.

i- The valve can be lifted by arod 34, which is fastened to its upper end and extends up through the tubular steerin post. The to of-the-rod issecured to the 45.

ub of an auxi iary hand-wheel 35, located, preferably, just below the main hand-Wheel, the spokes of the auxiliary Wheel passing through longitudlnal slots in the hub of the main wheel. By grasping the rims of both Wheels they can be squeezed together, thus lifting the'rod and coming the valve. The adjacent-faces of t e wheel rims are preferably flattened to -'pe1-1nit them to fit together. A. helical spring 36 encircles the .valve-rocl and abuts between the valve and one or more stationery stops 3?. inside the steering- 0st. This, spring closes the valve when 316 auxiliaryhand- Wheel is let go.

With the valve closed the parts'are locked by the liquid in the cylinder which reven-ts the gistons from being. moved. 11 highspee cars the valve may be adjusted to at low a slight leakage, so that the main,hand-' wheel can be slowly moved to efiect small deens into the space he teched ton-hem,
