GLOBE HOLDER Filed Dec. 1932 2 Sheets-Sheet 2 ISnventorJ (Ittorneg v Patented June 5, 1934 UNITED STATES PATENT OFFICE GLOBE HOLDER Alwin G. Steinmayer and Robert L. Smythe, Milwaukee, Wis., assignors to Line Material Company, South Milwaukee, Wis., a corporation of Delaware This invention relates to globe holders and is particularly directed to globe holders adapted to be positioned on the upper end of an ornamental pole for holding a transparent globe in place.

Objects of this invention are to provide a novel form of globe holder which is so made that it is impossible for water to enter the apparatus or for the water to freeze and lock the mechanism against operation, or for the water to freeze and lock the globe in place against removal.

Further objects are to provide a novel form of globe holder in which there is a minimum of exposed portions, the manipulating part of the locking means being substantially the only exposed part of the mechanism, and in which a construction is provided which precludes the entrance of dirt or rain into the apparatus or into the globe.

Further objects are to provide a construction in which an actual sealing effect is produced between the globe and the gasket or other member carried by the globe holding apparatus, in which yielding pressure means are provided for 5 directly engaging the globe so as to prevent any chance of cracking or unduly stressing the globe adjacent the attaching means.

Further objects are to provide a construction which is of very simple form, which is cheap to make, and which may be very quickly and easily operated. Y

Embodiments of the invention are shown in the accompanying drawings, in which:

Figure 7 is a fragmentary face view, partly broken away, of the structure shown in Figure 5.

Figure 8 is a sectional view of a still further form of the invention. 1

Referring to the first form of the invention, particularly Figures 1, 2 and 3, it will be seen that the pole l is provided with an upper finishing ring 2, the ring being held in place in any suitable manner, as by means of screws 3, which are threaded through the ring and which fit into a groove or into apertures formed in the upper end of the pole. Preferably a groove is formed in the upper end of the pole.

The ring is provided with an upper face 4 upon which a cork or other gasket 5 is positioned and preferably cemented to the upper face of the ring. The ring is provided with an inner upwardly projecting annular flange 6, which is notched at a plurality of equally spaced points, as indicated at '7 in Figure 3. Preferably a plurality of lugs 8 project inwardly from the ring to support the socket, not shown.

The globe 9 of transparent material rests upon the cork or other gasket 5 and is preferably provided with an enlarged reinforcing or beaded lower portion 10. It is to be noted that the inner surface of the globe adjacent its lower portion slopes outwardly, as shown in Figure 2.

The holding means for the globe comprises a plurality of resilient fingers 11 which are preferably slotted, as indicated at 12 in Figure 3, so as to allow the parts of each finger to separately adjust themselves to the inner curvature of the globe when the fingers are forced into locking position, as shown in Figure 2, the fingers being relatively stiff but nevertheless being somewhat yielding so as to prevent cracking or unduly stressing the globe. The fingers when rocked into their locking position, as shown in Figure 2, very securely lock the globe in place and also force the globe downwardly into binding engagement with the gasket, thus eflecting a watertight joint.

At this point, it is to be noted also that the globe is exterior of the flange 6 and consequently there is no outer flange inside of which the globe is positioned and within which water could collect. Therefore, it is clear that the solid freezing of the parts together due to collecting water is avoided by this construction. Instead, the construction is such that the water is readily shed and does not enter the apparatus, nor does it accumulate around the lower portion of the lobe.

A further feature in this connection is the fact that the manipulating shaft 13 for operating the fingers is housed or shielded by the overhanging flange 14 of the ring 2, such locking shaft being provided with a manipulating handle or outwardly turned portion 15.

The shaft 13 extends through the ring 2 and also through an inwardly positioned bearing support 16 formed integrally with the ring. A cam 17 is pinned, as indicated in Figure 3, to the shaft 13, the shaft being, however, free to slide and rotate within its bearings.

The cam 17, see Figure 4, is provided with a slanting face 18 which may terminate in a fiat portion indicated at 19 in Figure 3. The cam bears against an upwardly projecting rib or member 20 formed integrally with the ring and, therefore, as the shaft is rotated, it is caused to move forwardly by means of the cam. The cam is provided with a pair of stops or shoulders, indicated by the reference characters 21 and 22, see Figure 4, so as to limit its rotation in either direction.

Each spring finger is provided with an aperture through which its corresponding shaft 13 projects to thereby prevent unseating or removal of the finger. Each finger is provided with a transverse rearwardly projecting rib 23, see Figures 2 and 3, which bears against the front of the cam, the front of the cam being a plane surface as shown in Figures 2 and 3. Thus as the shaft is rotated, the finger is pressed forwardly. However, the lower end of the finger is loosely pivoted within a slot between a pair of upstanding lugs 24, see Figure 2, formed integrally with the ring 2 and constituting, therefore, a fulcrum for the spring finger.

The spring finger is forced rearwardly by means of a spring 25 loosely surrounding the shaft 13 and bearing at one end against the ring and at the other end against a washer contacting with the spring finger, see Figure 2.

In assembling the device, it is a simple matter to position the parts and slip the shaft 13 there through subsequently forcing a pin 26, see Figure 3. through each cam and its corresponding shaft.

In the form of the invention shown in Figures 5, 6 and 7, itv will be seen that a reciprocatory plunger or rod 27 is provided and reciprocates through an aperture 28 formed in the ring 2. This rod is threaded at its inner end and is provided with a spool-shaped member 29 which is screwed onto the rod and locked in place in any suitable manner, as by means of the lock nut 30. This member 29 is provided with relatively widely spaced flanges, as may be seen from Figure 5, between which arms 31 of the forked end of a spring finger 32 are positioned. This spring finger is pivoted upon a shaft or pivot member 33 carried by inwardly projecting portions 34 formed integrally with the ring 2 and are pref= erably secured to such pivot member by means of a cotter pin or split pin 35. t is preferable to provide the forked arms 31 of the spring finger with forwardly projecting ribs indicated at 36 in Figure 5, so that the forward flange of the member 29 will bear against such ribs when the rod or plunger 27 is forced inwardly.

The means for forcing the rod inwardly comprise a small lever or finger piece 37 which is pivoted as indicated at 38 to a bracket 39 formed integrally with the ring 2. This finger piece is preferably made of sheet metal and is of the order of a channel-shaped bell crank lever. It

has inwardly projecting arms indicated at 40 in Figure 6 which carry a transverse pin 41, see Figure 5. The pin 41 slides within a vertical slot 42 formed in the head 43 of the rod 28.

It is to be noted from reference to Figure 5 that when the rod is forced all the way in and the finger piece is in the position shown in Figure 5 that the pin 41 is above the center of the pivot pin 38 and consequently the rod 27 is locked against outward motion.

It is obvious that the member 29 may be very readily adjusted so as to provide the necessary spring pressure for the finger and may be locked in place by the lock nut 30.

In the form of the invention shown in Figure 8 very much the same idea as that shown in Figures 5, 6 and '7 is followed. However, thering 2" is provided with a slot 44 within which the reciprocatory rod 45 moves. This rod has a slight rocking motion as it is pivoted, as indicated at 46, directly to the inner arm 47 of the bell crank lever or finger piece 48. It does not slide in a horizontal line inwardly and outwardly as does the rod or plunger 27. It has a slight rocking motion as well as the sliding motion, the rocking motion being provided for by the slot 44 formed in the ring 2".

The spring finger 49 is pivoted upon the member 50 in a manner similar to that previously described and is provided with an opening 51 through which the reduced ends 52 of locking nuts 53 pass. These locking nuts are screwed into their correct adjusted position and are locked against each other, their reduced ends 52 freely passing through the opening 51 of the spring finger 49. It is apparent, therefore, that when the finger piece 48 is rocked upwardly and outwardly that the pressure on the spring finger is relieved and its upper end is rocked inwardly. However, when the finger piece is pressed in the position shown in Figure 8, it is apparent that the spring finger is pressed into engagement with the inner side of the globe, not shown.

In each of the last two forms of the invention it is clear that the overhanging flange 14 shields the outwardly projecting portion of the mechanism.

The form shown in Figure 5 is practically sealed and prevents the entrance of water.

The form shown in Figure 8 is substantially closed against the entrance of rain, but it is possible that some dust may find its way into the device. However, in both the first and second form of the invention the device is substantially sealed against the entrance of dust or of rain.

In the form shown in Figures 5 and 8 it is apparent that the inwardly projecting arms of the finger pieces contact with the end portion of the flanges 14 and consequently limit the inward rocking motion of the finger pieces.

In the form shown in Figure 1, it is apparent that the stop is provided by the shoulder 22 of the cam 17, see Figure 4.

In each form of the invention it will be seen that it is practically impossible for rain to enter the apparatus and consequently there is practically no chance of water freezing and locking the parts of the mechanism against operation.

Also it is apparent that the manner in which the globe is positioned and the relative association of the parts, see particularly Figure 2, is such that water is shed very readily from the apparatus and consequently there is practically no chance of the freezing of the globe tightly to the apparatus.

In all forms of the invention it will be seen that very simple mechanisms have been provided and that these devices may be very readily constructed and are relatively cheap to make. Also that they are very quick to operate as there is merely a quarter or half turn necessary for any one of the manipulating members.

Although this invention has been described in considerable detail, it is to be understood that such description is intended as illustrative rather than limiting, as the invention may be variously embodied and is to be interpreted as claimed.
