' CONTROL-LEVER MOUNTINGr Application filed November 18, 1918.

To all whom it may concern:

Be it known that I, JosEr-H W. NELSON, a subject oftheKingdom of Sweden, and a resident of St. Cloud, in the county of Stearns and State of. Minnesota, have invented certain new and useful Improvements in Control -Lever Mountings, of which the following is va description, reference being had to the accompanying drawingkwhich forms a part of my specification.

y invention relates more especially to the mountings for the levers whereby the carbureter and ignitionapparatus of an automobile motor are controlled from the seat of the operator.

The invention has for its object the provision of a construction whereby the control levers will be properly maintained in place and yet at the same time permit the control levers to be easily and quickly removed when occasion requires, without necessitating a complete dismantling of the various parts of the controlling vmechanisms as is the case especiallyin constructions where the carbureter and ignition apparatus are located on what may be termed the far side of the motor and the control levers or mechanisms therefore extend across the front of the motor and then lengthwise of the near side of the motor,relative to the location of the operator,lto the dash of the automobile at a point within easy reach of the operator.

With the control levers constructed and mounted in the manner heretofore employed, in order to permit complete access to certainparts of the motor for the purpose of repair and the like, it hasbeen necessaryto remove the mountings or brackets and the various parts of the control levers in order to permit proper access, thus resulting not only in loss of time, but often in the loss of parts. With my improved construction, the control levers may be quickly removed from their mountings orbrackets without in any way disturbing the latter and without necessitating acomplete disassociation of all parts of thelever mechanism; thus also permittingthecontrol levers to be quickly replaced and roperlysecured in their mountings or brac ets. I p i As my invention is more especially adapted for use in? connection with a control lever of the-type referred to, namely where the carbureter .is controlled from the side of the motor opposite to that on which the carbureter is located, I haveillustrated my inven- Specification of Letters Patent.

tion in its adaptation tothe intermediate member or rocker-arm portionv of the control lever, namely the portion of the mechanism which is disposedtransversely at the forward end of the motor; and therefore have shown my invention as applied to a cross-member of the chassis at the forward end thereof. The advantages of my invention and the construction will be more fully comprehended from the following detailed description of the accompanying drawing wherein Figure l is an elevation of a cross-member of a chassis, with portions broken away; disclosing the connecting member or rockerarm of the control mechanism, and the con- .nectingarms orlinks at the ends thereof.

- Fig. 2 is a detail View in perspective of one of the mountings or brackets and a portion of the intermediate or rocker member, connecting link or armand portion of the reach-rod or lever.

Fig, 3 is a detail view in perspective of the upper end of one of the mountings or brackets.

Fig. 4 is a detail sectional view taken on the line H of Fig. 1.

Fig. 5 is a detail view partially in section, illustrating a modified manner of securing the arms, from that shown in Fig. 2, to the ends of the rocker-element or rod.

The invention, as previously stated, is more especially intended for mounting the control lever of the c-arbureter of an automobile motor, namely the mechanism whereby the-carbureter may be controlled from theseat ofthe operator; and in its specific exemplification comprises a pair of bracket members or mountings 5, 5 preferably identical in formation and construction and consisting preferably of'fiat metallic strips or plates of any desired length; with the lower ends thereof bent so as to be angularly disposed and shaped to fit the configuration of the cross-member 6 of the automobile chassis. In the particular construction shown,

where thsoross-member 6 is given a downward curvature, as shown in Fig. 1, the lower ends or feet of the brackets 5, 5 are preferably made arcuate, as shown at 7 so as to extend flush with the upper portion of the cross-member 6, to which the bracket members 5-, 5 are intended to be securely fastened or riveted, as shown at 8, so as to maintain the brackets in fixedposition. The

brackets 5F' are securedito the cross-frame 6,

. 9, asclearly shown in Fig. 3; the aperture 9 and slot 11 thus providing the upper end of bracket member 5 with the bifurcations 12, 12, which are disposed toward each other as shown in Fig. 3, but in spaced relation so as to permit the insertion of the rocker-element 10 and bushings into the aperture or socket 9. In order to permit the proper assembly of the parts and permit elements of somewhat greater dimensions to pass through the restricted passage or slot 11 between the bifurcations 12, 12, the bracket members 5 are slit, as shown at'137; the slit 13 extending for a predetermined distance lengthwise of the bracket from the aperture or socket 9, as clearly shown in Fig. 3.

Itis evident that with this construction,

that although the element to be inserted is of somewhat greater diameter than the distance between the bifurcations 12, it may be forced into socket 9 as a result of the springy or yielding nature of the upper end of the bracket due to the long slit 13.

In order to provide suitable bearings for the rocker-member or rod 10 in the brackets, I prefer to provide the member 10, at both ends thereof and coincident with the location of brackets 5, with the flanged bushings 14, the bushings being provided with circumferential flanges spaced apart as shown in Figs. 1 and 4:. The'bushings 14: may be of any suitable bearing material or metal such as bronze, steel and the like and are formed so as-to permit member 10 to oscillate or rock in the bushings; while the bushings are intended to be firmly clamped or held in the apertures 9 of the brackets 5, the

space between the flanges of the bushings being just suflicient to receive the brackets and'prevent any vibration between the various members and also prevent any displacement. With the bushings 14 constructed of suitable material and having sliding fit with the rod or rocker-member 10,

the latter is free to oscillate and easy operation ofthe control mechanism thus permitted. In practice, the body portion of the bushing is made slightly greater than the aperture 9, as well as the distance between bifurcations 12, 12, so that a firm or sn'ug -relation between the brackets or mountings 5, 5 and bushings 14 will be provided; the

insertion of the bushings into the aperturesof the brackets being made possible by the slits 13; the slightly sprung condition of the slit ends of the brackets prevent ng any chatter between the parts during operation of the automobile The outer ends of the rocker-member or rod 10 in Figs. 1 and 2 are each shown provided with a link or arm 15 having a hubportion 16 apertured to receive the end of the member 10; the hub portion of the arm 15 being slit from end to aperture thereof,

as shown at 17 in Fig. 2, therebyproviding. the two separated portions or lobes-l8 which are adapted to be drawn together by means of set-screws 19, thus firmly clamping the links or arms 15. onto the ends of the rockerarm 10. Instead of securing the links or arms 15 to the ends of rocker-element or rod 10 as just described, these arms15 may be secured in place in the manner shown in Fig. 5; namely by simply providing. the hub portion 16 of'the arm and the ends of the rod 10 with registering holes adapted to receive a suitable pin a shown at 19 in I Fig; 5.

The opposite ends of the links or'arms 15 are each aperture'd to receive a pin20 which is also adapted to pass through the apertured end of the reach-rod or lever 2l; the pins 20 being maintained in place in any suitable manner as for example by cotter pins, as at 22. his evidentthat'upon removal of the cotter pins,the pins 20 may be withdrawn from the apertures in the ends of the links or arms 15 and the reach-rod or member 21, thereby permitting the reachrod to be readilyremoved when occasion requires. The hnksor arms 15, at both ends 7 of the rocker-rod 10, maybe identical in construction and method of attachmentas shown; the link at one end of the mechanism having the reach-rod or lever, which extends to the dash-board, secured thereto; while the other link or arm 15 has the reach-rod or ."member secured thereto (not shown) which extends to the carbureter and controls the valve thereof; or to the ignition apparatus as the case may be.

When it is desired to remove the control mechanisms, the reach-rods'or control members of the respective mechanisms may be 1 readily disconnected from. the links or arms 15 by the removing of the cotter-pins as previously described, thus permittingxtherocker-rod 10, with the bushings 14, together with the links 15, to be removed from orslipped out of the mountings or brackets by exerting an upward pull thereon,'thereby causing the bifurcations 12 to spring apart or separate suificiently to permit the bushings' 14 to "slide through the slot 11; such separatlon of the-bifurcations, V stated, being permitted by the elongated slit as previously 13 disposed lengthwise of the mountings or brackets 5.. A construction is thus provided which may be readily assembled and put into place and easily and quickly removed for replacement or to permit proper access to the motor, without necessitating the removal of the mountings or brackets; and at the same time the control levers or mechanisms are firmly held against vibration and undesirable rattling of the metal and the resultant noise entirely eliminated.

I have shown and described what ll believe to be the simplest adaptation of my invention, but the same may be altered in certain respects and applied to diiferent uses without, however, departing from the spirit of the invention.

What I claim is '1. A mounting of the class described, comprising a bracket of resilient metal provided with a lower attaching end, while the upper end is socketed and provided with a slit eX tending from the socket and disposed lengthwise of the bracket.

2. A mounting of the class described, comprising a pair of brackets of resilient metal, one end of each bracket being formed to provide an attaching end, while the opposite end is socketed and provided with a slit extending from said socket a predetermined distance lengthwise of the bracket, in combination with a rocker-element adapted to be seated in the sockets of the brackets, the rocker-element being provided with flanged bushings, the flanges of said bushings being spaced apart so as to extend on opposite sides of the respective brackets.

3. A mounting of the class described, comprising a bracket composed of a strip of resilient metal, one end whereof is angularly disposed to provide an attaching end while the opposite or free end is provided with a socket, the outer end of the socket being of less cross sectional dimension than the cross sectional dimension of the main portion of said socket, said end of the bracket being slit from said socket length-wise of the bracket for a predetermined distance so as to permit slight separation of the divided portions of said outer end of the bracket.

4:. A mounting of the class described, comprising a bracket of sheet metal having one end angularly disposed to provide an attachingend, while the other end is provided with an aperture or socket of greater dimensions at the lower end than at the upper end of said socket, the bracket being slit from the lower end of said socket for a predetermined distance lengthwise of the bracket so as to permit slight spreading of said socketed end, in combination with a control member adapted to be movably mounted in said brackets, and flanged bushings loosely mounted on said member so as to permit movement of the latter in said bushings, the flanges of the bushing being in spaced relation so as to receive the bracket therebetween.

5. A mounting of the class described,.comprising a bracket composed of a strip of resilient metal of comparative width, one end whereof is angularly disposed to provide an attaching end, while the other end is provided with a socket of greater cross sectional dimensions at the lower end than at the upper end thereof and formed to provide inwardly disposed bifurcations at the outer end of the bracket, the bracket being provided with a slit extending from the lower end of said socket for a predetermined distance throughout the length of the bracket so as to permit slight separation of'said inwardly disposed portions at the outer end of the bracket.

6. A mounting of the class described, comprising a pair of brackets composed of strips of sheet metal of comparative width, the lower ends whereof are angularly disposed to provide attaching ends, while the opposite or free ends are slit longitudinally for a predetermined distance so as to provide a pair of bifurcations formed to curve toward each other and provide a socket therebetween of greater dimensions at the lower end of the socket than at the tip of said bracket, in combination with a control member or rod, bushings loosely mounted on said member and of greater cross sectional area than the distance intermediate of the bifurcations at the tips of said brackets, and link members or arms removably secured to the ends of said control member or rod.
