G. M. BOLL. LOG BUOY. .APPLIOATION rum) MAY 16, 1908. 9 1 9,53 1 Patented Apr. 27, 1909. WITNESSES. INVENTOR rm: NORRIS FIYRR! co \vAvlluqmN. n. h UNITED STATES PATENT UFFICE. CARL M. BOLL, OF MERRILL, WISCONSIN. LOG-BUOY. To all whom it may concern: Be it known that I, CARL M. BoLL, a citizen of the United States, residing at Merrill, county of Lincoln, and State of Visconsin, have invented new and useful Improvements in Log-Buoys, of which the following is a specification. My invention relates to improvements in log-buoys or floats. The object of my invention is to provide a simple and e'flicient float or buoy, which is adapted to be quickly and easily attached to heavy logs or timber, the specific gravity of which is such that they will not otherwise float in water. My invention pertains more specially to the mechanism by which a float may be quickly and easily attached to the upper surface of a log at a slight distance from its respective ends, whereby the liability of the same being broken or detached by contact with other logs or stationary objects is avoided and whereby when the log has been transported to a mill or market, the buoy maybe quickly removed therefrom and again and repeatedly used for like purposes. My invention is further explained by ref erence to the accompanying drawings in which, Figure 1 represents a side view of my device in connection with a submerged log. Fig. 2 represents an end view of the device, shown in Fig. 1. Fig. 3 is an enlarged de tail drawing of the fastening dog removed from the log, showing lug 10 curved upwardly instead of downwardly. Fig. el represents amodified form of fastening device, in which the dog is connected with the float through a slidable instead of a pivotal connection, and Fig. 5 represents the dog inserted through an aperture of a rigidly con nected bar. 1 represents a log submerged in water, 2 represents the buoy by which the log is caused to float in the water, the buoy 2 being preferably provided at its respective ends with fastening lugs 3, which are secured thereto by bolts or ri 'ets i, in any convenient manner. 5 is a fastening dog, which is. pivotally connected with the lugs 3 by the pivotal bolt 6. The dog 5 is provided with a fastening barb. 7, which is adapted to be driven into the surface of the log, whereby the fioat Specification of Letters Patent. Application filed May 16, 190B. Patented April 27, 1909. Serial No. 433,256. is securely held in place. The dog also comprises an impact head 8, which is adapted to receive the strokes of a mallet or hammer when driving the barb 7 into the surface of the log. The dog 5 is also preferably provided. 'ith an elongated slot 9 for the reception of the pivotal bolt (3, which permits of the required movement between the pivotally connected parts which is produced as the barb is being driven into the log. The dog is also preferably provided with a rearwardly projecting lug 10, which facilitates in disengaging the barb from the log and between which and the log a crow bar may be inserted for such purposes. The float 2 is preferably made of sheet metal but may be made of wood or other substances of less specific gravity than water. In the modified form, shown in Fig. 4-, the float 2 is provided at its respective ends with an elongated loop 12, while the dog is pro vided with a lateral projection 13 through which an aperture l i is formed, for the reception of said loop 12. whereby when the barb T is driven into the log, said lateral projection 13 is free to slide down upon said loop until the barb has penetrated the required distance into the log. It will be understood that in other respects, the modified form is adapted to perform the same functions as the dog shown in the other figures. In the modified form shown in Fig. 5, a horizontal bar 15 is connected with the float ing dog 18. The dog 18 is provided with an aperture 17 for the reception of a fastening dog 18. The dog 18 is provided with laterally projecting lugs 19 and is connected with the float by a chain 20. Havii'ig thus described my invention what I claim as new and desire to secure by Letters Patent is, 1. The combination of an elongated float adapted to be secured at its respective ends to the sides of a log, fastening dogs movably connected with the respective ends of said float, respectively provided with a barb and a contact head against which the strokes of a hammer may be applied for forcing said barb into the log. 2. The combination of a cylindrical float, a fastening dog movably connected with the respective ends of said float, provided with a barb, a head against which the strokes of a hammer may be applied for forcing the gaging said dog from a log and means for movably connecting said dogs With the respective ends of said float. In testimony whereof I atfix my signature in the presence of two Witnesses. barb into the log and a projecting lug for disengaging the fastening dog from the log. The combination of a float, a pair of fastening clogs, adapted to be forced into a 5 log and means for pivotally connecting said float and (310 's to 'ether. k. The coiiibination ofahollow cylindrical CARL BOLL' float, fastening clogs respectively comprising Vitnesses: a contact head, a barb adapted to penetrate WILL GEHRKE, 10 a log, a laterally projecting lug for disen ILL RADATZ.
