  • Patent number: 4875676
    Abstract: A weight training apparatus that allows the user to safely perform free-bar type bench press exercises, both in the standard fashion and in the more effective eccentric contraction fashion is described. The weight bar is attached to a cable system that incorporates a safety stop to prevent the weight bar from crushing the chest of the user in case of accident and especially features a guided sled proximal the user's feet and connected to the weight bar by the same cable system and whereby the user may, at his option at any time during the exercise, partially support or lift the weight bar by engaging the guided sled with his feet and pushing it using his leg muscles.

  • Patent number: 4852888
    Abstract: This invention relates to a target board for electrically sensing the penetration of darts and similar missiles that do not penetrate entirely through the target. More specifically, the invention relates to the construction of a target board that is adapted to be a sensing device to trigger an electrical scoring device not of this invention wherein an electrical trigger circuit is closed upon the impact of a pointed missile partially penetrating the target board. A unique feature of this invention is that it allows the use of regulation-grade metal-pointed throwing darts of the type preferred by serious dart players, with no modifications made to the dart to accommodate the triggering of the target board circuit.

  • Patent number: 4799877
    Abstract: This invention is a safety device for cigarette lighters fueled by butane or other compressed or liquified gas. The invention is a barrier adapted to selectively engage the thumb layer of the lighter to restrict the motion of the thumb layer, thereby to prevent the release of gas to the burner tip. The restricting member is supported by a band or sleeve that is adapted to at least partially surround and slidably engage the body of the lighter. A sliding motion of the band on the lighter engages or disengages the restricting member with the thumb lever; this motion may be selectively prevented or allowed by the selective engaging or disengaging of a spring-loaded member having a laterally extending projection adapted to fit into an opening in the lighter's structure.

  • Patent number: 4789017
    Abstract: This invention relates generally to funnels; more specifically it relates to funnels intended for use with fluids used in engine compartments, such as in transportation vehicles. Examples of such fluids are crankcase oil, transmission fluid, anti-freeze or other coolant fluids, brake fluid, and power steering fluid. The invention is a liquid transfer system including a funnel with a dust cover that may be stored on a funnel support while the funnel is in use and that may include a piercing tool on its inner surface capable of puncturing the lids of containers used with the funnel. Also claimed is such a liquid transfer system including a support that holds the funnel in a vertical position during storage, a drip catcher, and an axially extendible and compressible spout.

  • Patent number: 4721244
    Abstract: This invention relates to a device for signaling the delivery of mail, newspapers, or parcels in an enclosed receptacle that is open on at least one end, that end being the receiving opening for such deliveries, there being no closure for said opening. The principal application is for the commonly-used roadside newspaper delivery tube, the opening of which generally faces away from the residence so the presence of the newspaper is obscured from view by the resident for whom the newspaper is intended. The invention comprises a trigger element that blocks a portion of the delivery opening of the receptacle and a flag element that signals the delivery, these elements operatively slidably engaging one another.

  • Patent number: 4699380
    Abstract: A finger grip insert for a bowling ball is formed of a resilient hollow body having an outer configuration adapted to be inserted into a finger hole of a bowling ball. The outer end of the insert is open to permit insertion of a bowler's finger into the interior of the hollow body. The interior of the body has a generally triangular shaped cross section defined by three spaced flat sides with respective concave portions of the body extending between respective pairs of the flat sides to allow the bowler's finger to stay in a relatively natural position while enhancing the feel and adding lift and power to the bowler's delivery as a result of the substantial finger to insert contact area provided by the finger grip insert.

  • Patent number: 4690182
    Abstract: This invention relates to a device to hold the lever of a nozzle assembly in a position to open a valve controlling the flow of fuel from the nozzle. The principal application for this device is on the gasoline delivery nozzle assembly at a self-serve gasoline station. The device, in addition to being a convenience for the average user, is an aid to the user who may be physically handicapped or inconvenienced by arthritis or other disabling condition that would otherwise deter him from using the more economical self-serve gasoline pumps.

  • Patent number: 4671500
    Abstract: A symmetrical clamping device for producing bonded uniform panels from narrow strips of wood as well as laminated boards glued together. Includes two relatively long guide plates provided with appropriate linkage mechanism capable of exerting pressure to the entire surface being clamped while applying force to the ends in a direction that is perpendicular to that surface when actuated manually by way of appropriate jack screws disposed at each end of the guide plates or automatically by using power cylinders in combination with linkage and an end bolt incorporated therein, to insure participation of bondable material in the process of clamping and conformation to the surfaces of guide plates which may have a straight flat surface or an irregular shape so as to produce desired final product.

  • Patent number: 4628914
    Abstract: This invention relates to a device for providing therapeutic support to the penis of a man who suffers either partial or total sexual impotence, which device thereby allows nearly normal sexual activity between him and his partner. The device comprises parts that are mounted on spring-loaded hinges that create external pressures on the corpora cavernosa, the erectile tissues within the penis, compressing them so less blood is required to achieve erection and/or maintain the penis in an erect state. A significant feature of this invention is that it can be applied to or removed from the penis after coitus has begun and without complete disengagement of the male organ from the female.
