An end compartment receives an applicaator head which is stored within the compartment in a suitable liquid. The applicator includes a suction bulb and the head which is in the form of a cylindrical body having a peripheral edge of approximately the diameter of the outer edge of the lens and a membrane extending across the cylindrial body. The membrane has an upper surface for engaging the lens which is perforated so that suction applied by the bulb draws the lens onto the membrane and then further suction distorts the membrane to pull the sides of the cylindrical portion inwardly to pinch the lens and break the seal.

Abstract: A line block is used for producing profiles on bodies, especially filled automobile bodies. The block is composed of a series of thin, stacked plates with fine cutting teeth along one edge of each plate. The plates are clamped together with bolts so that they can be loosened and pressed against a profile to be matched so that the cutting edges of the plates follow the profile. The bolts are then tightened and the line block used to produce the desired profile. Notches in the cutting edges of the plates are offset on adjacent plates in the block to accommodate material removed from the body being profiled.

Abstract: An implement such as a broom or rake has a supplementary handle attachment mounted upon an upper side of the conventional shank of the implement. The handle attachment includes a first hand grip section in the form of a bar parallel to the shank and spaced upwardly from the shank. A pair of further hand grip portions are attached to the bar at respective ends of the bar and extend therefrom upwardly and forwardly toward the implement head. The further hand grip portions consist simply of a simple cylindrical body shaped solely to receive the hand of the user gripped therearound without any further handle sections at the upper end. The handle attachment allows a user to select the preferred hand grip locations to allow operation of the device without bending.

Abstract: A feeder for cylindrical bales is of the tombstone type that is it includes a lower circular band defined by hoops and an upstanding sheet of material forming a skirt. U-shaped frames or tombstones are then attached to the outer frame and extend upwardly therefrom with the animal able to reach between the tombstone for grasping feed from a bale confined within the feeder. In accordance with the improvement of the present invention, the tombstones are bent inwardly and upwardly so that the animals front legs are confined outwardly away from the bale while the animal can reach over the inclined portion of the tombstone and through the vertical portion of the tombstone to the table. The animal is encourged to feed within the outer frame and thus any waste is deposited within the outer frame and cannot be trampled or spoiled. The animal is inhibited from pressing its shoulders against the frame thus reducing damage or breakage and excessive movement of the feeder.

Abstract: A threshing concave or concave guide for a combine harvester is described. The concave is positioned in its conventional location on a combine, however, the design has been modified. The crop is directed into the concave by threshing cylinder rasp bars. As the crop enters the guide, at its base, there are positioned a number of angled bars that direct the incoming crop away from the center of the concave. Traditional concaves move the grain toward the center of the device. The angled bars of the present invention distribute the load more evenly along the concave surface, thereby resulting in a decreased wear and tear of the concave and rasp bars. The design also reduces the damage to separate grain as the grain slides into the leading edge of the device rather than abruptly hitting the sharp edge of a first cross bar, as in traditional concaves.

Abstract: An attachment device for a tractor of the type including a front end loader bucket and a rear mounted backhoe comprises a rear axle and ground wheels for positioning beneath the backhoe tower and attachable to the rear of the tractor by forwardly extending straps. Beneath the bucket is permanently attached a kingpin device formed by a plate and pin mounted upon a bracket which is so shaped that the pin and plate are wholly above the plane of the lower wall of the bucket so that the bucket can be normally used with the kingpin devide in place and such that when the bucket is fully retracted the kingpin is presented vertically downwardly. Thus the bucket can be positioned upon a conventional fifth wheel of a road tractor.

Abstract: A weather strip for attachment to a jamb for engagement of a flexible portion of the weather strip against a closure member for example a door comprises an attachment portion of rectangular shape for attachment to the jamb and a flexible portion of blade-shape or cylindrical shape for flexible engagement with the door. The attachment portion is formed of an exterior thin wall surrounding a hollow interior with the wall being co-extruded with the flexible portion. The resultant body is thus relatively flimsy and is rendered rigid by the addition of a stiffener element inserted into the hollow interior defined by the walls.

Abstract: A ground working implement includes a tool bar and a tool element which can be pulled across the ground by its attachment to the tool bar by a bracket and link system. The link comprises a U-shaped arm with a transverse portion parallel to an axis of rotation of the tool. The transverse portion is carried in a bracket depending from an underside of the tool bar. The transverse portion is formed of a tubular member which has a projecting portion extending radially from the axis of the tubular portion. The projecting portion has two side plates which rub against side plates of the channel to prevent side to side movement of the tool. The tool can raise or lower by rotation of the transverse portion of the channel or by lifting of the transverse portion in the channel within the limits defined by a base plate of the channel or a transverse restraining pin. The tool is latched in a raised position by a latch plate attached to the projecting portion which wedges underneath the base plate of the channel.
