Abstract: A leather product decorated with predetermined indicia and a method of making the product. Preferably, a leather belt is provided with a liner attached thereto along a predetermined section of the rear of the belt to define a pocket. Decorative indicia such as letters, symbols, or the like are then marked on the belt immediately opposite the liner. A resistant cutting strip inserted into the pocket facilitates filagreeing by enabling spaces between the marked indicia to be removed through cutting or chiseling without damaging the belt. After unwanted material between the desired decorative indicia has been removed through filigreeing, the cutting strip may be simply removed from the pocket. In a preferred embodiment of the invention the decorative indicia may be colored prior to removal of the liner, and/or a background strip of predetermined color may be drawn into the pocket as the liner is removed to highlight the filigreed decoration.

Abstract: The present sewer pipe cleaning device may be used on a conventional plumber's fish tape. The device comprises a rowel-like member having curved tines thereon, with the axis of the rowel-like member being transverse to the axis of the sewer line. The rowel-like members are rotatable mounted on a non-rotatable member in such manner that the rowel-like member may be moved into the debris which is clogging the sewer pipe. The rowel-like members each have a plurality of curved, sharpened tines, secured thereto which tines extend in the same direction, with the tines of each rotatable member lying in a plane perpendicular to the axis of the respective rowel-like member. The rotatable members are spaced apart so they will rotate in apertures in flanges on the mounting member, when moved in one direction.

Abstract: Attachments for broadcast combines which have been converted into row type combines, in which the bearing guard attachment shields the shaft bearing on the lower ends of the drum shafts from becoming covered with vegetation which wraps therearound during the harvesting operation. The vegetation wrapped around the shaft bearing and the lower ends of the shafts precludes free circulation of air which cools the bearings and prevents the loss of lubricant therefrom due to expansion of the lubricant resulting in leakage from the elastomer seals.

Provision is made for molding the cap or cover integrally with the handle and with the portion to which the brush bristles are attached. Further provision is made to mold a socket in the stem to receive the brush bristles.

Abstract: This vibration damping device is of a character to minimize the shaking or vibrating of levers, particularly gear shift levers on heavy trucks and other heavy machinery, which when operated over rough terrain at high speed, creates a noise that becomes almost unbearable, resulting in great fatigue on the part of the operator. The present arrangement utilizes an aggregate, shot, or a metallic material within the compartments of a device which may be secured around the lever, as by a zipper, a draw string and tape, so that the sudden and high frequency vibrations are minimized and dampened without interfering with the operation of the gear shift lever. The compartments of the device are divided longitudinally to maintain the aggregate or shot evenly distributed longitudinally. The compartments are also divided transversely, so when fastened around a gear shift lever, they will form circumferential pockets. The device is easily mounted on a gear shift lever and may be removed in a minimum of time.

Abstract: A motor operated abrading device for abrading surfaces, such as vehicle bodies, which device utilizes a cylindrical housing of the motor on which to secure a sheet of abrasive material, so when the cylindrical motor housing is rotated an abrading element is formed, without having to drive the abrading element with chains, gears, belts or the like. The motor will have any suitable source of power, such as electricity or air, so long as the outer housing is cylindrical and rotatable with respect to a stationary shaft. When air is used as the motive power, the air, which is cool, passes through the motor, and will maintain the motor cool as well as the cylindrical drum and the abrasive surface which is mounted thereon. The motor may be used with or without a guide frame to control the abrading element with respect to the surface being abraded.
