To all whom it may concern:

Be it known that I, DAVID M. DEARING, a citizen of vthe United States, residing -at Jackson, in the county of Jackson and State of Michigan, have invented certain neWand useful Improvements in R11nnin,g,|f-Grearv for Motor-Vehicles; and I do declare the followexact description of the invention, such as will enable others skilled in the art to -which it appcrtains to make and use the same.

This invention. relates to improvements in running gear for motor vehicles.

The object of the invention is to provide a pivotal yieldingconnection between the front end 'of thesupporting frame and the front axle and means whereby the weight of the frameand body of the vehicle is applied to the axle near the ends of the same.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan view of the front. end of the motor vehicle running gear constructed in accordance with 'the invention; Fig. Z is a lfront end view of the same, parts being broken away and in section; Fig is a central verticallongitudinal sectional view; Fig. 4 is a plan view of the front end of the running gear showing a modified form of the inven-` tion adapted for use with elliptical side springs; Fig. 5 is aside view of the same on"` the line 5-5 of Fig. 4; Fig. 6 is a front View Q of the upper. and lower members of the conl nection, partsbeing broken away and in secj tion; Fig. 7 .is a central vertical longitudinal section of the same on the line 7-7 of Fig. (l.

Referring more particularly to the drawing, 1 denotes the side bars 4of the supporting frame ofthe running gear, the forward ends of which are connected together by4 a frontk c ross'bar 4orfplate 2. To the lower side of the cross bar or plate 2 is bolted or otherwise secured the upper member 3 of mynnproved front axle eonniaztion. The memberv 2 is preferably in the 'l'orin ol` a bar having on its opposite edges downwardly extelnling parallel [langes 4- which are incwased 1n width at `the center of the bar to form a. bearing 51:'i`sshown. 4

vln the bearing portion 5A of the flanges are Vformed alined bearing apertures G.

Adapted to beengaged-with the upper. inem ber 3 of the connection is thelower spring engaging member 7, said member preferably consisting of an angular bar provided at its center with a solid bea-ring portion 8 which is adapted to be inserted'between the bearing portions 5 of the flanges 4 of the upper member 3. In the central bearing portion l 8 ofthe lower connecting member 1s formed abearing aperture which, when the parts are assembled, alines with' thebearing aperture 6 inthe ianges of the upper member and through said alined passages or apertures is inserted a tubular bearing sleeve S), by means of which the upper and lower me lbers of the connection are pivotally connected together. The'bearing sleeve receives the cranking shaft 10 which is mounted therein and is provided on its outer end with y the usual crank handle 11. The lower'inember 7 tapers or inclines from thel center of the member toward the ends thereof and the ends are bent upwardly to form brackets 1Q, on the upper ends of which are formed vertically disposed sockets 13 with which are adapted to be engaged the upper ends of guide pins 14, the lower ends of which are secured to the front axle' 15 adjacentto its outer ends by means of clips 1G, or other suitable fastening devices.

0n the pins-14: between the enlarged lower ends of the sockets 13 and the clips 1G are arranged coiledsupporting springs v17, which receive and yieldmgly support the weight ofthe running gear and body of the vehicle. By arranging the springs 17 near the outer ends of the axle 15, the weightof the vehicle body and running gear is imparted to the axle near its engagement with the sup porting wheels thereby relieving the central portion of the axle from such weight, and thus reducing the possibilityofbending or breaking the axle. The pivotal engagement of the lower connecting `member with the upper member permits the outervendsA of the axle to rock or move up and do\'v.n,`thus relieving the running gear and operating'parts of the vehicle f rom undue strain.

()n the lower' side of the upper connecting member 3 adjzueent toy its outer ends are arranged upper bumpers 1 8, while on the upper sides o'l' the lower member 7 are .arrangedliower bumpers 1S).V The bumpers 1S and 1S) are provided. to limit the roc-king movemei-it of the axle, andnby forming the bumpers of greater Aor lesslength, the rocle ving movement o f .the axle-may beregulated.

:Between the .-onterl ends offthelnpper and lower connect-ing members and around `said bumpers are preferably arranged coiled cushioning or shock absorbing springs 20, by means of which jars or shocks occasioned by the vehicle passing over rough or uneven surfaces are taken up. The axle 15 is connected with the side bars of the supporting frame by brace rods 21 which are connected at their front ends by universal joints 22 with the clips 16 and at their rear ends by universal joints'23 with the side bars in the common well-known manner to permit the necessary movement of the parts.

' In Figs. l.1t-7 of the drawings is shown a Y modified arrangement of -the connecting members, whereby they are adapted for use in connection with elliptical side springs in stead of coiled springs as shown in the first figures of the drawing. The connection shown in the last Iigures of the drawings comprises an upper frame engaging bar 24 having on its opposite side edges downwardly projecting flanges 25 in the center of which are formed alined bearing apertures 26'. The lower connecting member 27 is secured in a similar manner to the member 7 of the iirst form of the device and is adapted to be inserted between the anges. 25 of the upper member and in the center of said yowervmember is formed a bearing aperture 28- which, when the parts are assembled, alines with Athe bearing apertures 26 and through said alined apertures is'inserted a tubular bearing sleeve 29, through which the cranking shaftlO is inserted. On the upper side of the member 27 on the opposite sides of and near the center are formed stop lugs f 30 immediately above which on the inner side of the upper member 25 are arranged bumpers 31, which are adapted to engage the lugs 30 -and thereby limit the rocking movement of the lower member 27. Ii" desired, coiled springs 32 may be arranged between the bumpers 31 and the lugs 30., On the outer ends'of the member 27 are formed brackets or hangers 33 having right angular outwardly projecting hool -shaped ends 34, which are adapted to be engaged with the lupper sides of elliptical side springs 35,

which are secured at their lower sides to f the front axle 15 adjacentl to its opposite ends as shown. With this form of the connection may be used any kind of elliptical, bowed or leaf springs `to yieldingly support the frame and body of the vehicle.

From the arrangement shown in the drawings, it will be seenthat the bumpers and t e bumper prings maybe placed at any desired\position` between the center and outer ends of the connecting members. It will also be understoodrthat'in the last form of the invention, the brace rods21 are connected to the axle and -frame in the samermanne'a's 'under side ot' the frame,

described in connection with the first form of the invention.

From the foregoing description, taken in eonnection'with the accompanying drawings, the construction and operation of the pended claims.

Having thus described my invention, what I claim 1s:

1. In a motor vehicle running gear, the combination of a supporting frame, a front axle, an upper connecting member on the under side of the frame, a lower connecting member having its central portion housed within said upper connecting member and its ends arranged over the ends of the axle, a sleeve inserted through the central portions of said members, to pivotally connect the same, cushioning devices arranged between said members at opposite sides of said sleeve, and springs arranged between the ends of the lower connecting member and the axle.

2. In a motor vehicle running gear, the

combination of a supporting frame, a front axle, an upper connecting member on thc a lower connecting member having its center housed withinA the upper member and its ends arranged over the ends of the axle, a sleeve' inserted through the centers of said melnbers to pivotally-connect the same, springs arranged between the ends of the lower member and the axle, bumpers arranged between the upper and lower connecting members, and springs arranged on said bumpers.

3. In a motor vehicle running gear," the combination of a frame, a front axle, an upper connecting member on the under side of the frame having depending flanges, a lower connecting member litted between said flanges and having its ends disposed over the ends of the axle, a sleeve inserted transversely through the center of the lower connecting member and the ianves of the upper connecting member to pivota ly connect said members and form a bearing for the cranking shaft, cushioning devices between the members, and springs on the axle engaging the endsof the lower connecting lmember.

In testimony whereof I have hereunto set y hand in presence of two subscribing witnesses. l i DAVID M. DERING.
