AUTOMOBILE-RADIATOR-COOLING MEANS.

Application filed May 31, 1917.

To all whom it may concern:

Be it known that I, CARL E. W. SPEISER, a citizen of the United States, residing at Green Castle, in the county of Sullivan and State of Missouri, have invented certain new and useful Improvements in Automobile- Radiator-Cooling Means, of which the following is a specification.

This invention relates to automobile radiator cooling means, and more particularly to a radiator fan adapted to be mounted closely adjacent the inner face of a radiator so as to cool the same by directing an air current through the radiator.

One of the main objects of the invention is to provide a fan for cooling an automobile radiator which is so constructed as to be quickly and easily adjusted to vary the pitch of the fan blades so as to control the fiow of air through the radiator thus permitting accurate control of the cooling of the radiator. A further object is to provide a fan the blades of which are pivotally mounted so as to be rockable for the purpose of varying their pitch, simple and efficient means being provided for quickly and easily rocking the blades about their pivotal axes and securing the same in rocked adjustment. A still further object is to provide simple and eflicient means for adjusting the fan blades in the manner stated and for securing the same in adjustment. Further objects will appear from the detailed description.

In the drawings Figure 1 is a fragmentary side view of the front portion of an automobile with a fan constructed in accordance with my invention applied, partly broken away and sectioned to show details of construction,

Fig. 2 is a top plan view of the fan and the supporting bracket therefor partly broken away.

Fig. 6 is a section taken on line 6-6 of Fig. 5.

Fig. 7 is a section taken substantially on line 7-7 of Fig. 6.

A supporting bracket 1 is securely bolted to the engine 2 at the front thereof. This bracket is provided with an integral forwardl extending bearing sleeve 3 formed at its inner end with an annular shoulder 4 Specification of Letters Patent.

Serial No. 171,911.

Two upwardly and rearwardly inclined arms 5 are formed at the inner end of the bearing sleeve and serve to pivotally support an operating lever 6 which is mounted at its approximate center on a rod 7 secured in the upper end of arms 5 and passed through the lever.

Lever 6 is provided at its upper end with a fork 8 in which is pivotally secured the forward end of an operating rod 9 the inner end of which is connected by a universal joint 10 to the forward end of a cylindrical member 11 slidably mounted in collar 12 carried by an upright 13 which is rigidly secured to a base board 14 closely adjacent and at a right angle to the instrument board 15 of the automobile A. Member 11 is provided in its upper face with an axially extending groove or key way 16 which receives a key 17 fixedly secured in the collar 12. By this means, member 11 is free to move axially through collar 12 but is secured against rotary movement. An operating rod 18 is seated in an axial bore in member 11 and is provided with a radially extending stud 19 which is operative in a helical slot 20 formed in member 11. By rotating rod 18 axial movement will be imparted to member 11, the direction of this movement depending upon the direction of rotation of the rod. This movement will be transmitted by rod 9 to lever 6 thus rocking the lever on its pivotal axis.

Rod 18 is extended so as to project beyond the inner face of instrument board 15, and an operating crank or handle 21 is secured on the inner end of this rod. This handle is operative over the face of an approximately semi-circular adjusting plate 22 which is provided with a series of equally spaced adjusting points 23 which are dis posed concentric with rod 18, these points projecting beyond the face of plate 22 so as to engage the under face of handle 21 so as to grip the same frictionally and thus lock the handle in adjustment, the handle having a certain amount of resiliency for this purpose. Each of the points 23 is given a number, these numbers designating the amount of rotation which has been imparted to the operating rod 18 when the handle 21 is set on a given point. To prevent looseness or play, the operating rod 18 is provided a short distance from the inner face of instrument board 15, with a collar 24 secured thereto. An expansion coil spring 25 is confined between this collar and a flanged bearing ring 26 secured to the inner face of the instrument board and acting as a hearing member for rod 18. This spring acts as a cushioning element and serves to hold the finger 19 of rod 18 in contact with the outer wall of slot 20 in member 11 thus permitting adjustment of the fan blades in a manner to be described.

An adjusting shaft 27 is slidably mounted in bearing sleeve 3. This shaft is of such length as to project forward of the fan hub 28 which is rotatably mounted on the bearing sleeve adjacent the forward end thereof. The fan hub is extended inward and provided with spaced

peripheral flanges

29 and 30 to form a pulley 31 about which is passed the fan belt 32. The inner end of the fan pulley 31 is provided with an inner annular recess which receives the annular shoulder 4 at the inner end of bearing sleeve 3. Axial movement of the fan hub rearwardly of the bearing sleeve is thus positively prevented. The forward end of bearing sleeve 3 is threaded to receive a securing nut 32, between which and the outer or front face of fan hub 28 is interposed a bearing washer 33. By this means, the fan hub and the belt pulley integral therewith are mounted on the bearing sleeve for free rotation but are effectually secured against axial movement thereon. Adjusting shaft 27 is provided on its outer end with an integral disk head 34. Head 34 is provided with a central annular groove which cooperates with a similar groove formed in the inner face of adjusting ring 35 mounted concentric with the head to provide a race way for the hearing balls 36 interposed between the head and ring. By this means, ring 35 is mounted on head 34 so as to have independent rotary motion, but is movable with the head axially of the fan hub. For adjusting the shaft 27 so as to move head 34 and ring 35 toward and away from the fan hub, the adjusting lever 6 is provided at its lower end with a fork 37 which straddles the inner end portion of shaft 27 being connected thereto by a .pin 38 secured through the shaft and extending through slots 39 formed at the lower ends of the arms of fork 37. By rocking lever 6 in the desired direction shaft 27 may be moved either inward or outward through the bearing sleeve 3.

A rim 40 is mounted concentric with fan hub 28. A plurality of equally spaced and radially disposed fan blade-supporting rods 41 are pivotally mounted at their inner ends 1n the fan hub 28. These rods are reduced at their outer ends to form bearing fingers 42 which are pivotally mounted in the rim 40. By this means, the fan blade supporting rods 41 are pivotally mounted so as to be rockable about their pivotal axes. A fan blade 43 is secured to each of the rods 41 so that, by rocking the rods the angle or pitch end of this arm is pivotally secured by a screw- 45 to the ring 35, this screw being inserted through a suitable aperture in the arm and threaded into the ring. By moving the adjusting shaft 27 so as to move head 34 and ring 35 forward or away from the fan hub, the rods 41 will be simultaneously and similarly rocked about their pivotal axes so as to adjust the pitch of the fan blades 43. By thus adjusting the pitch of the blades, I am enabled to regulate with great accuracy the amount of air which is drawn through the radiator B thus permitting very accurate control of the cooling of the radiator. This adjustable fan may be used inconnection with any suitable instrument connected to the radiator for indicatingthe temperature of the same. If it is seen that, at any time, the radiator is above the desired temperature, the fan blades 43 may be quickly and easily adjusted so as to increase their pitch, thus increasing the amount of air which is drawn through the radiator and reducing it to the desired temperature. .For thispurpose, the graduated adjusting plate 22 is of material assistance, as it can be quickly ascertained by experience just exactly which point 23 the handle 21 should be placed on under ordinary conditions so as to maintain the radiator at.

proper temperature for a particular auto-- mobile.

The operation of this fan will be more clearly understood from Figs. 1 and 2 of the drawings. If it is found desirable to increase the amount of air which is drawn through the radiator so as to lower the temperature of the same, the handle 21 will be moved over the adjusting plate 22 toward the right hand end thereof, as considered in Fig. 1 of the drawings. When the handle 21 is thus operated, the rod 9 will be moved inward or rearward of the machine, thus swinging the fork 37 of lever 36 forward and forcing the adjusting ring 35 away from the fan hub 28. When this takes place, fan blade supporting rods 41 will be rocked about their pivotal axes so as to swing the fan blades in thedirection indicated by the arrow in Fig. 2 of the drawings, thus materally increasing the pitch of the blades and consequently the amount of air which is drawn through the radiator by the fan. When it is desired to decrease the flow of air through the radiator the handle 21 will be moved in the opposite direction thus reversing the operation.

It will be evident that there may be slight changes made-in the construction and ar rangement of the different parts of my invention without departing from the field and scope of the same, and I intend to include all such variations, as fall within the scope of the appended claim, in this application in which a preferred form only of my invention is disclosed.

What I claim is In radiator fans, the combination of a fixed bearing sleeve, a fan hub rotatably mounted thereon, radiating fan blade supporting rods pivotally mounted in said hub so as to be rockable about their pivotal axes, each of said rods being provided with an &

angularly disposed adjusting arm, a shaft slidable through said sleeve and projecting forward 01": the fan hub, said shaft being provided on its outer end with an adjusting head, an adjusting ring carried by said head and mounted thereon for independent rotary movement, the outer ends of said adjusting arms being pivotally, secured to the adjusting ring, and means for adjusting said shaft through said bearing sleeve.

In testimony whereof I afiix my signature in presence of two witnesses.
