2 Claims.
My invention relates to apparatus enabling indulgence in the sport known as log-rolling under simulated conditions, and the primary object of the invention is to provide a simple, efficient and practical arrangement of this character whereby the sport mentioned may be carried on regardless of the time,- the place, and weather conditions. I I Other important objects and advantages. of my invention will be apparent from the a reading of the following-description taken in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.
In the drawings:
Figure 1 is a general side elevational view,
partly broken away and contracted, showing a preferred embodiment of my invention.
Figure 2 is a top plan view thereof.
Figure 3 is an enlarged fragmentary vertical longitudinal sectional view taken through one of the bearing assemblies.
Figure 4 is a transverse vertical sectional view taken through Figure 1 approximately on the line 44 and looking toward the left in the direction of the arrows.
Figure 5 is a transverse vertical sectional view taken through Figure 1 approximately on the line 5--5 and looking toward the left in the direction of the arrows.
Referring in detail to the drawings, the numeral 5 generally designates a log of suitable diameter and length, which may, according to the choice of the operator, be a finished or an unfinished log, the same having substantially squared ends 6 and I to which respective bearing assemblies 8 and 9 are secured by means of bolts l0. Each of the bearing assemblies comprises a hollow cylindrical shell II which has two interior annuli I2 and 13, the annulus l2 being located near the middle of the shell II with the annulus [3 between it and the right hand end of the shell as illustrated in Figure 3 of the drawings. The right hand end of the shell is axially threaded as indicated by the numeral 14 to receive a cap [5 while the opposite end of the shell is exteriorly threaded as indicated by the numeral [6 to receive a packing compressing cap [1, the latter being provided with an opening I8 through which the stub shaft l9 revolubly extends. The stub shaft I9 extends also through several layers of suitable packing 26 pressed in the end of the shell I I against a washer 2| which works against a ball-bearing 22 whose opposite side abuts the laterally outward side of the an- -nines l2." The stub shaft 19 as an enlarged portion 23 which turns in thebearing 22 and an annular enlargement 24 which bears i against the laterally inward side ofthe bearing. The stub shaft l9 has a second annular enlargement 25 which bears against the longitudinally inward side of the ball-bearing 26 which is seated in the right hand end of the shell ll and'itself abuts the longitudinally outward side of the annulus l3. The bearing 26 receives an enlarged diameter portion 21 of the stub shaft l9 and the right hand end of the shaft is threaded as indicated by the numeral 28 to receive the tightening nut 29 which bears against a washer 30 which, in turn, bears against the longitudinally outward face of the bearing 26. At circumferentially spaced intervals the outside of the shell, II has attached thereto generally L-shaped brackets 3|, these brackets being fastened to the shell along the part which lies between and in the neighborhood of the annuli l2 and I3 as illustrated in Figure 3, and the right angularly related foot portions 32 are pierced with bolt-receiving holes 33 throughwhich the bolts l0 pass into the log 5.
The left hand extremity of the shaft 19 is threaded for a considerable distance as indicated by the numeral 34 and" provided thereon with two spaced nuts 35 and 36 for engaging the opposite sides of the vertical member 31 of the respective one of the two supports or landing stages 38 and 39, between which the log 5 is by the means described revolubly supported. It is obvious that by adjusting the positions of the nuts 35 and 36 along the threaded portion 34 of the shaft l9 that logs of slightly different lengths may be readily accommodated.
Each of the landing stages comprises a heavy horizontal bolster 40 notched to receive the heavy vertical member 31 flush with the laterally inward edge thereof as indicated by the numeral 4| in Figure 4. The lower end of the vertical member 31 rests on the ground or other support (not shown) and at its inner side there is attached at the same level a cross member or foot 42, which like the bolster 40 extends at equal distances on opposite sides of the vertical member 31. Attached to the top of the vertical member 31 and similarly extending equally on opposite sides thereof is the platform 43 which extends laterally outwardly to seat in notches 44 in the upper ends of the angulated stiles 45 of the step-ladder or stairs 46, the steps being constituted by horizontal cross members 41 extending between the stiles. Upper and lower V- shaped brackets '48 and '49 are secured to the inner edges of the stiles and to the adjacent edge of the bolster 40 while reinforcing blocks 50 are secured in place to take up the space between the stiles and the vertical member 31 and the platform 43 to provide a thoroughly braced structure.
Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of my invention thereto except as may be required by the scope of the subjoined claims.
Having described the claimed as new is:
1. A device of the character described comprising a pair of vertical supports, said supports invention, what is being horizontally spaced apart at a substantially greater distance than the length of a log to be rolled, horizontal stub shafts secured to and projecting from the facing sides of said vertical supports, said stub shafts being of relatively small diameter and being in axial alinement, elements rotatably mounted on the free ends of said stub shafts, a relatively large diameter log positioned between said vertical supports and having its opposite ends substantially spaced from the said supports, means fixedly connecting said elements to the ends of said log in substantial alinement with the axis of the log, and spacing means extending between said supports on opposite sides of said log, said spacing means being connected to space said vertical supports and brace the same in position.
2. In a log-rolling game device, a pair of opposed supports, stub shafts mounted on said supports, said stub shafts being in axial alinement, a log rotatably supported by said stub shafts, tubular elements secured to the respective opposite ends of said log and extending longitudinally therefrom, said tubular elements being sleeved on said stub shafts, and bearing assemblies housed within said tubular elements and disposed circumjacent the respective stub shafts.
