Abstract: A surgical case cart having a closed container supported on a chassis. The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the container can be completely opened with the front and portions of the sides being exposed by the door panels wrapping around the side and back. The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction. The lower edges of the door panels provide a baffle effect to reduce the movement of contaminated air into the cart. The top of the cart contains an overhang lip to prevent liquids from spilling into the container. Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect. The intersection between the back, sides and chassis is constructed to avoid the possibility of collecting contamination and bacteria.

Abstract: The present invention relates to a locking mechanism which has particular application to a medicine cabinet. The device includes a first member which is adapted to be connected to the pivoting door of a medicine cabinet and a second member which is adapted to be connected to a side wall of the medicine cabinet receptacle portion itself. The member attached to the medicine cabinet receptacle wall includes a latching mechanism actuated with a pivoting movement to enable the latching and unlatching of the first mentioned member and thereby the locking and unlocking of the door of the medicine cabinet. The inventive locking mechanism may easily be utilized in other applications where it is desired to selectively lock a door.

Abstract: A latch has spaced inner and outer plates formed with respective coaxial bores. The outer plate is formed at its bore with at least one notch and the inner plate is formed adjacent its bore with at least two angularly offset and axially extending cutouts. A plug extending through the bores and rotatable therein about the axis has an outer head in the outer bore and accessible from outside the plates and an opposite inner end exposed inward past the inner plate. A locking dog extends radially from the plug in the space between the plates. An inner abutment washer is secured to the inner end of the plug and spaced axially inward of the inner plate and a retaining washer angularly nondisplaceable on the inner end of the plug has a bump engageable in the cutouts of the inner plate. A compression spring braced between the washers urges the bump into the cutouts. A key engageable with the plug head has a radial tab complementary with the notch of the outer plate.

Abstract: A one-piece molded plastic quarter-turn fastener is provided for releasably latching a panel to a cabinet. A generally disc-like body has a flanged and slotted stem axially extending therefrom to be snapped into a hole in the panel. Projecting radially from the body is a latching lip for engaging and disengaging a cabinet. A positioning boss is provided to permit a quarter-turn rotation of the fastener with a detent provided at each rotational limit.

Abstract: A locking device for a sliding closure unit having two panels, at least one of which is slidable, embodies an elongated stop member which is pivotally connected to one panel in position to rotate selectively to an inoperative position to permit relative movement of the panels and to an operative position to limit relative movement of the panels.

Abstract: The latch assembly is provided with a locking collar and a pair of knockouts so that the latch assembly can be easily converted to a latch-lock assembly by simply inserting a cylinder lock in the proper knockout, depending upon whether the assembly is used in a right-hand or left-hand installation. The conversion of the assembly may be made before or after installation of the latch-lock assembly.

Abstract: A document clamping device formed from a series of pivotally interconnected links. Adjacent pairs of links are movable between a first position of mutual alignment and a second position at right angles to one another about a pivot. Locking means are provided to hold the links firmly in the second position and preferably also in the first position. This locking means may be in the form of spring-loaded ball catches or resilient bosses on one link locating within recesses on the other link of a pair. Pivoting may be achieved either by means of a pivot pin or by mutually engaging configurations on the interconnected ends of two adjacent links.

Abstract: A holder for a window made up of a holder bracket and a lever having a frictional end pivoted to the bracket. The bracket is attached to the window frame so that the lever frictional end can swing down and engage the window at an acute angle to the window so that it will hold the window and prevent it from sliding down. The lever can also be swung up so that the frictional end will engage the window below the pivot to prevent the window from being raised.

Abstract: A lock for use in conjunction with a window panel slidably supported in a track of a channel member includes a stop member which is permanently and translatably secured in the track of the channel member. The track includes a generally tubular portion extending the length thereof and the stop member includes a generally U-shaped lower portion, with the distal end of the U-shaped portion slidably disposed in the tubular track portion. The stop member includes a web portion extending upwardly from the U-shaped portion, and a top panel extending orthogonally from the upper end of the web. The stop member may be pivoted about the portion engaged in the tubular part of the track to increase the frictional engagement therewith and prevent translation of the stop member. The top panel of the stop member includes obliquely extending edges which are engaged by the sliding window panel to rotate the stop member into the locked position.

Abstract: A fireplace stove comprising a generally rectangular metallic housing adapted to extend into a fireplace opening, with penetration being limited by a flange around the housing which engages and seals against the face of the fireplace. A metallic inner fire shell is closely spaced within the inner surfaces of the housing to provide airflow passages between them. An air inlet with a blower is located at the lower end of one side of the housing and a narrow, hot air outlet extends across the top. Air is directed to flow almost completely around the fire shell for maximum heating. An air inlet with a blower is located at the lower end of one side of the housing and a narrow, hot air outlet extends across the top. Air is directed to flow almost completely around the fire shell for maximum heating. An access door is held in sealed engagement by a spring latch and a combustion air duct in the door extends into the interior so that the air entering thereto is preheated before actual contact with the fire.

Abstract: Sliding closures such as sliding glass doors or windows are locked by a stop member mounted in the upper track for the closures. The stop member is elongated longitudinally of the track and is pivoted about a transverse horizontal axis to permit its movement between an upper retracted position and a lower door-abutting position. The principal improvements comprise: (a) a stationary shoulder which abuts a part of the stop member when in its door-abutting position to resist excessive forces applied against the stop member by sliding movement of the door; (b) stationary pivotal supports for the stop member connected on both sides thereof to the track; and, (c) the supplemental use of a lateral projection attached to an outer sliding door for abutment by the stop member. Further, there is provided a novel spacer assembly in the upper track to limit upward movement of the door.

Abstract: A retainer cylinder is rotatably mounted in the bore of a housing cylinder and selectively latched against rotation by means of a resilient latching assembly. The housing cylinder is formed with a longitudinally extending groove and a corresponding recess is formed in the retainer cylinder. In one arrangement, the resilient latching assembly comprises a flat spring captured in the housing cylinder groove and having an intermediate portion resiliently urged into the retainer cylinder recess. A dog slidably mounted in the recess is cammed by a key to force the spring element from the recess and allow rotation of the retainer cylinder. In a second arrangement, the same housing cylinder allows for handle operation of a retainer cylinder wherein the latching assembly comprises a cam pin resiliently mounted in the retainer cylinder recess.
