Abstract: A sulky characterized by a single supporting wheel positioned behind, or partly beneath, the frame of the sulky, and where the driver's seat is positioned behind the single supporting wheel for added weight concentration and better driving control. The frame has a generally U-shaped plan configuration, unlike the present bow shape, and is typically made from a light weight metal which decreases in vertical dimension in a direction towards the head of the pulling horse.

Abstract: A door arrangement having particular adaptability for use on a storage cabinet characterized by a frame positioning a reversible or interchangeable panel, the latter being slideable into a received position upon removal of a portion or section of the frame.

Abstract: An archery bow sighting arrangement and method characterized by the use of a mechanical scale for establishing the desired shooting range, the sight point being determined by the intersection of a cursor or index line and calculated scale lines representing the various range distances. The cursor line may be movable with respect to a fixed pattern of scale lines or the cursor line may be fixed and the scale lines rotatable. The invention permits the instantaneous setting of sight markings, in contrast to the present approach of separately marking a piece of tape for each distance.

Abstract: A filter mask characterized by a filter receptacle which carries a liquid, such as water, into which a plurality of air inlet tubes extend. Air is drawn through the liquid by reason of the vacuum caused by breathing, filtering the contamination, and then passes through an associated face mask. The filter mask effectively removes contaminates in the air, as various forms of dust, solid or semi-solid particles, pollen, chemicals and the like.

Abstract: An arrangement for dispensing grain, or other like material, characterized by (1) a cushion box communicating with a material passageway, at a material receiving bin, in a ball and socket relationship, including a material outlet and a slot for eliminating trapped material; and, (2) a ball joint, at the upper end of the material passageway, providing versatility in application.

Abstract: A message display arrangement having particular adaptability for use on a wheeled vehicle, such as a bicycle, characterized by a display unit for presenting a succession of indicia information in response to the movement of the vehicle. Structure on a spoke of the vehicle wheel selectively rotates an indicia carrying segment wheel in front of a source of light, where the indicia pattern is transmitted to the display unit through a system of fiber optic strands.

Abstract: A toy in the form of a miniature vehicle characterized by a replaceable hood, as found on a conventional automobile, truck, or the like, spring-urged into a normal operating position upon assembly. The hood may be made of deformable material, e.g., aluminum foil.

Abstract: A hypodermic syringe projectile for animal usage characterized by a hollow housing which receives an axially movable body member. A chamber for receiving treatment liquid is defined between an end of the body member and an end of the housing which mounts an injection needle. The body member is retained in a fully retracted or filled position by flexible fingers on a wall thereof which selectively engage an end of the housing and which are maintained in such retained position by a weight. Movement of the weight upon impact with an animal releases the body member for movement from the retained position and forces the treatment liquid from the chamber through the injection needle.

Abstract: An attachment for a tennis racket characterized by a pair of resilient retaining members releasably positioned on the frame of the racket and arranged to receive a tennis ball resting on a court or other surface, and to raise such with upward movement of the racket for subsequent removal and use. With the ready grasping of a tennis ball, the tennis racket attachment eliminates, or at least minimizes, the countless bending and stooping formerly required for tennis ball retrieval during the course of a tennis game.

Abstract: A solar collector panel characterized by an integral base having a heat transfer liquid channel and weir at each end of a corrugated heat transfer surface. The channel and weir define a self-contained heat transfer liquid system which provides for the even distribution and collection of such liquid over and from the heat transfer surface.

Abstract: A railroad safety and warning arrangement characterized by a single foot pedal which initiates the consecutive operation of a locomotive bell and both the locomotive bell and a locomotive whistle. The operation of the preceding alarms are discontinued by means of a release mechanism which selectively disengages a notched control arm from a side edge of the foot pedal.

Abstract: An integrally molded plastic lubricant fitting which has the check valve at the outlet of the fitting instead of at the inlet, and where hydrostatic pressure from the lubricant within the body of the fitting maintains the fitting in an operative position. The latter is further assured through the provision of circumferential ribs on the outer surface of the body of the fitting, such coacting with the inner surface of a predrilled fitting hole in a positive manner.

Abstract: A tent frame assembly characterized by a two-part corner member or casting secured together by an independent nut and bolt arrangement, where the nut is dimensioned so as to permit ready grasping and tightening during the assembly procedure. The invention further includes a pre-positioned rotatable sleeve forming part of a corner brace assembly to expedite installation and to achieve a stabilized frame.

Abstract: A platform lift adapted for use on framework disposed within a doorway of a vehicle characterized by a platform and a ramp simultaneously movable by hydraulic means from a stored position to an operative position, and where the hydraulic means further serves to raise and lower the platform. Provision is made for independent manual movement of the platform in the event of any hydraulic failure, adding further utility to the arrangement.
