STEERING-WHEEL POST.

tit?) from suitable metal Application filed August 25, 1916.

T0 aZZ whom it may concern:

Be it known that I, GRANT E. SMITH, a resident of the city of Poughkeepsie, in the county of Duchess and State of New York, have invented an Improvement in Steeringheel Posts, of which the following is a specification.

his invention relates more particularly to steering wheelsposts, that is to say, the easing which surrounds and in part supports the steering wheel shaft. Steering wheel posts have heretofore generally been cast and thereafter machined to size or drawn from metal to form a tubular post, and in practice considerable inconculty of casting and machining, or drawing the same to exact size to fit the adjacent parts.

The principal object of this invention is to obviate these inconveniences and difiicultics, by provling a steering post which, notwithstanding its tubular construction, will maintain itself in rigid and proper alinement at all times and particularly during shipping, and which may be molded or otherwise formed with such exact dimensions as to enable it readily tobe assembled with its associated parts, i

he accompanying drawings show one embodiment of the present mvention, and there- Specification of Letters Patent.

produce a structure of 'tages of drawn metal plastic material, nally of the post,

Patented Jan. 23, 1917. Serial No. 116,761.

33 of Fig. 1; and Figs. 4 and 5 are detail sections, the planes of the sections being respectively, the lines H and5-5 in Fig. 3. he principal object, aforesaid, of my invention may be accomplished by the use of a plastic material for the steering wheel post, such material being preferably condensite or bakelite or one of the condensation produots of phenol and formaldehyde. substances may be readily molded to exact size and thereafter hardened by suitable heat treatment. lVhen so molded and hardened to form a tubular post, such materials great inherent rigidity admirably adapted to hold its shape, and in such a structure the advantages of a heavier cast and machined post are provided without excessive cost while the disadvantubular construction are entirely eliminated. Moreover, by our bedding in the molded material the connecting wires. as presently described, a tubular post of added strength can be produced.

As shown in the drawings, plastic material a. is preferably, though as at presentbelieved not essentially, molded upon a wooden core Z). This wooden core may be of materi..l assistance in molding the plastic material and it will, to a certain extent, effect an economy in manufacture because less plastic material may be required when used. The condensite or like material permeates the wood of the core, thereby greatly strengthening the core and so unites itself to the wood during the molding process that a substantially integral steering postis formed. The wooden core maybe-tubular or solid when the molding is effected, and if solid it is subsequently bored to receive a steering shaft 0, and to provide a slight clearance as indicated at (Z.

e requisite number of Wires (1 previously referred to may be preferably to lie longitudias shown. As a preferred method of embedding the Wires in the plastie material of the post, they may he first .1nlaid upon or attached to the preferably Figure l is a side elevation of an illustra- Wooden core 6 in the positions whic they so tive steering wheel post assembled; the steerare to permanently occupy, before the plasing wheel, parts of the steering-gear and the tie material is applied thereto. The subsepost; Fig. 3

hood of a motor vehicle being shown partly in section and partly in elevation; Fig. 2 is a front elevation of the lower end of the is a longitudinal section on line quent covering of the core with the plastic material and the molding of the same there on secures the wires permanently in position and not only covers and protects them but may thoroughly and completely insulate them electrically. It may be entirely feasible in view of the insulating properties of the plastic material to embed bare wires in the post to form the several electrical circuits.

Suitable switches e to control the several electrical circuits may be mounted upon the steering wheel post in sutiicient proximity to the wheel to be readily accessible to the operator, and suitable outlets for the circuits may be provided by binding-posts f located preferably at the base of the column.

The switches herein shown are merely for purposes of illustration and the specific details of their construction and their operation inopening and closing the several circuits will be sulficiently understood and need not be herein described in detail. As shown, bases or mountings g for the switch boxes are molded or formed integrally with the plastic material while contact points h are embedded therein and held firmly in place thereby. The appropriate connections may be made between the contact points it and the wires 03 preferably before the plastic material is molded about the wooden core,

and, as in the case of the wires d, the contact points It together with the binding-posts f may be attached to and held in position by the wooden core during the molding and hardening of the plastic material. In the finished structure the contact points of the switches and the several binding-posts may be completely insulated by the plastic material molded around them.' Metallic or other caps i may be secured to the switch bases 9 and may carry appropriate switch control mechanism to cooperate with the contact points 72..

\Vhen the post is assembled, the lower end may be supported as usual by a collar y secured to the casing for a steering gear, denoted generally by 70, while its upper en may be supported by a usual to the dash m, (see Figs. 1 and 2). As shown in the drawings, the steering wheel shaft 0 is connected to and supported at its lower end by the steering gear is, while the upper end is journaled in the steering wheel post. To form a suitable bearing the plastic material of the post may extend inwardly beyond the wooden core at n;,the shaft being thereby journaled directly upon and against the plastic material.

In assembling the completed steering wheel post into the motor vehicle the'sevoral electrical circuits may be completed by connecting the leading ends of the several conductors attached to the vehicle to the respective binding-posts upon the lower end of the steering column.

An electrical circuit may also be provided for heating the steering wheel or for locating upon the steering wlnel rim a suitable switch button for closing a horn circuit and bracket Z bolted as V 7 ing of molded plastic the core, and a connecting wlre for con- 120 the means for completing, the circuit are herein provided as follows: the heating coil or l'luI'Il button not being shown in the drawings. A ring 0 may be connected to a wire 7; leading to a corresponding binding-post located at the base of the column, in the same manner as the connecting wires d. The ring 0 may be embedded in the plastic material at the top of the steering Wheel post and a brush 1" which is electrically connected to the heating coil or horn button by a wire 8, may be so mounted that as the wheel turns it will always maintain its contact with the ring. The return circuit may be through the steering wheel shaft to ground.

In the claims which follow the word condensite is used to refer generally to any plastic material capable of being molded to exact size and thereafter forming a rigid hardened insulating material. It is to be understood that the invention may be variously embodied and modified within the scope of the subjoined'claims.
