UNITED STATES WILLIAM G. DUNN, OF CLARINDA, IOWA.

MOTOR SUPPORT AND, THRUST MEMBER.

Application filed November 21, 1921,, Serial No. 516,849. Renewed August 7, 1924.

To all whom it may concern:

Be it known that l, VV'ILLIAM G. DUNN, a citizen of the United States, residing at Clarinda, in the county of Page and State of Iowa, have invented certain new and useful Improvements in} Motor Supports automobile accessories and has for its prin cipal object, to provide a novel attachment; for Ford automobiles to receive the thrust of the usual radius rod and to assist in supporting the weight of the motor, there by taking a great deal of strain from the usual hangers which are commonly attached to the fly-wheel casing of the motor to sup-- port the rear end of the latter. While these hangers are sufliciently strong to support the weight of the motor, they are often broken when the radius rod thrusts rear-- wardly upon the motor with unusual force and there is also danger of injuring other parts of the motor when such an occurrence takes place. 13y useof my invention, however, all thrust of the radius rod is taken up by a rigid transverse bar secured to the chassis frame and to the rear end of the motor.

A further aim of the invention is to provide a thrust receiving member for the radius rod, provided with an upwardly extending projection for snug reception in the usual ball socket formed in the lower side of the motor base, so as to brace the thrust member to some extent, although any appreciable amount of thrust is prevented from being transmitted directly to the motor, due to the rigid nature of the thrustreceiving member and its rigid connection with the chassis frame.

Yet another object is to provide an attachment of the class set forth which may be quickly and easily applied to any Ford machine without the necessity of making any alterations Whatever in the construction of the latter.

Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawings:

Figure 1 is a perspective view of a Ford motor and adjacent parts of the chassis, showing the application of my invention.

Figure 2 is a perspective View of the attachment and its securing means.

Figure 8 is a detail vertical sectional view as indicated byline 3-8 of Fig. 1.

Figure f is a vertical transverse sectional view .as indicated by line ll of Fig. 3.

In the drawings above briefly described, the numerals 1 designate the side bars of an ordinary Ford chassis frame, to which the usual hangers 2 are secured for supporting the rear end of the motor 3, said hangers being attached to the fly Wheel casing 41 in the well known manner. The lower side of the motor base is provided with the well known hemispherical socket- 5 which usually receives the ball 6 on the rear end of the radius rod 7, but in adapting my invention to the machine, the cap 8 which previously held the ball 6 in the socket- 5, is removed and said cap is later used to mount the ball in another socket with which the invention is provided.

In the preferred form of construction which is herein described and illustrated, a centrally depressed metal bar 10 is provided to extend across the chassis frame under the rear end of the motor 3, directly in front of the fly wheel housing 4;, the ends of said bar being provided with horizontal portions 11 whose inner and outer ends may be offset to some extent, longitudinally of the machine, if desired. In view of the fact that the portions 11 form rests for the rear end of the motor, I have hereinafter referred to these portions as rests. The outer ends of the rests 11 are adapted to underlie the side bars 1 of the chassis frame and to be secured thereto by any suitable means such as the U-bolts 12. In the present form of construction, it is necessary toemploy suitable spac ing blocks 13 between the rests 11 and the side bars 1, but it will be understood that the equivalents of these blocks might well be formed directly on the rests. The inner portions of the rests 11 underlie the usual flanges 14 on the front side of the fly Wheel housing 4:, bolts 15 being passed through the usual openings of said flanges and through bolt holes 16 formed in the rests. By securing the bar 10 in place in this manner, it supports a great deal of the weight of the motor 3 and is mounted in a sufficiently rigid ployed to hold said ball in the socket.

manner to effectively resist all strain exerted by rearward thrusting of the radius rod 7, which rod I intend to connect with the bar 10 as above suggested.

In the preferred form of construction, all parts of the bar 10 are formed of cast metal as shown, the upper edge of sald bar bemg provided with a forwardly extending flange 17 while its lower edge is equipped with a rearwardly projecting flange 18. These flanges permit the body portion of the bar to be in the form of a rather light web, due to their reinforcing effect, and I utilize the upper flange 17 in connecting the radius rod 7 with the bar. This upper flange is provided with a hemi-spherical projection 19 extending upwardly therefrom and adapted for, reception in the ball socket 5, while the lower side of said flange is formed with a hemispherical socket 20 extending into the projection 19 and adapted to receive the ball 6 of the radius rod 7, the cap 8 being e1;-

11 this connection, attention is directed mor particularly to Fig. 4, from which it will be seen that the flange 17 is formed with openings 21 through which the vertical bolts 22 extend from the motor base, said bolts pass ing through the usual openings in the cap 8 and carrying the well known springs 23 and nuts 24 on their lower ends.

The construction just described establishes an effective connection between the motor base and the bar 10, which serves to brace them relatively, but said bar is of sufficient rigidity to receive all rearward thrust of the radius rod without transmitting any undesirable amount thereof to the motor, Tthrough the instrumentality of the projection 19.

' My invention may be advantageously marketed and may be quickly and easily attached to automobiles without the necessity of taking them to a garage or other shop and when once installed, it will be seen that the motor and its hangers are relieved of the intense strain to which they are commonly subjected. Attention may further be direct ed to the fact that the invention. establishes a very rigid connection between the motor and the frame which prevents undue vibration of the former and resultant loosening of the hanger arms, which later produces rather serious transmission troubles.

As excellent results have been obtained from the details disclosed, they may well be followed, but I wish it understood that within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. A motor supporting and thrust receiv ing attachment for automobiles comprising a rigid depressed bar adapted to extend across a chassis frame under the rear end of the motor, means for rigidly securing said bar to the chassis frame and to the motor to take strain from the hanger-sol the latter, and means for connecting the usual radius rod of the automobile to said bar instead of to the motor, thereby taking additional strain from said hangers.

2. A thrust receiving member for aulomo bile radius rods having a projection for reception in the usual radius rod ball socket; of the automobile motor.

A thrust member comprising a bar adapted to extend across a chassis frame under the rear end of the motor, said bar having a projection for reception in the usual radius rod ball socket in the motor and being itself provided with a socket for the radius rod ball, and means for securing the ends of said bar to the chassis frame.

4. A thrust member comprising a bar adapted to extend across a chassis frame under the rear end of the motor, said bar having a hemi-spherical projection formed on its upper side for reception in the usual radius rod ball socket of the motor, said bar being provided with a dowmvardly opening hemi-spherical socket; extending into said projection to receive the radius rod ball, said last named socket being adapted for coaction with the usual cap to hold the ball in place,

and means for securing said bar to the chassis frame.

In testimony whereof I have hereunto set my hand.

WILLIAM (l. DUNN.
