Abstract: A two-part worm drive clamp embodying a first part in the form of a tensioning strip having a housing-enclosed, slack take-up worm at one end and a tab at its other end, and a second part in the form of a ribbon-like, band-forming strip having a tab-receiving cut-out or opening at one end and a longitudinal series of generally transverse, worm-engaging slots extending inwardly from its other end. The desired size of the clamp is attained by wresting the second part from a tandem or one-in-front-of-the-other array of unit band lengths in a roll of preformed band-forming stock, the requisite number of unit lengths being dependent upon the required size of the band of the clamp. An important feature of the invention resides in the nature of the interlock which is established between the tab and the tab-receiving opening, the interlock being such that it is unnecessary angularly to displace either part in order either to effect or disconnect the interlock.
Abstract: An adapter for temporarily and releasably attaching or connecting the eyepiece barrel of one telescope of a binocular to a camera of the type which has a deeply recessed lens, to the end that the optical or lens system of such telescope may serve as a telephoto lens system for the camera, while the other telescope of the binocular is capable of serving as sighting means for the user of the camera. An optical image diverter which is associated with the adapter projects into the camera recess and increases the eye relief of the one telescope of the binocular and carries the image backward or rearwards through the camera recess so as to retrofocus such image on the camera film with or without magnification or demagnification and without vignetting.
Abstract: A material mixing apparatus having a cylindrical mixing bowl within which there is disposed a rotary, power-driven, mixing assembly embodying a cylindrical turret which embodies an upper extension and carries about its periphery a series of material mixing components including lift plows and material cutters. When the apparatus is used for mixing materials which combine and liberate heat because of the addition of water or other liquid, the added water or other liquid is applied to the turret and its extension for wash-down purposes in order to avoid the creation of indestructible solid lumps in the material undergoing mixing. A novel turret configuration and a novel plow and plow holder arrangement which accomplishes efficient material agitation and folding within the bowl, constitute the principal features of the present invention.
Abstract: An alignment clip adapted for use in aligning two like reglets in end-abutting relation, such reglets each comprising a channel component including a bight portion and two flanges extending from opposite longitudinal edges of the bight portion and converging outwardly therefrom, said clip comprising a body portion adapted to overlie the adjacent ends of the bight portions of two abutting reglets, and flange means on opposite longitudinal edges of the body portion for engaging the reglet flanges to hold the reglets in alignment, such flange means including a snap-on flange.
Abstract: A spreader bar assembly which is designed for use in a concrete wall form and cooperates with a she-bolt on one end of a tie rod in preventing inward collapse of the adjacent side of the form prior to pouring of wet concrete between the opposed form sides. A washer which is loosely and telescopically received over the she-bolt bears against the outer side of the adjacent form side and is clamped thereto by a nut, while a pivoted spreader bar proper which is captured on the washer is capable of swinging movement in a vertical plane between a locking position wherein it passes across the front or outer face of the nut and assimilates any tendency for inward collapse of the adjacent form side, and an out-of-the-way position wherein it exposes the nut for manipulating purposes.
Abstract: A key ejector lock adapted for use in the door of a cabinet or other enclosure and which will eject the lock key in any rotational position thereof comprises a tubular barrel, a front end plug rotatable in the barrel and having a keyway extending therethrough, a rear end plug rotatable in the barrel and adapted for connection to a locking member, rotatable drive means interposed between the plugs for driving the rear end plug, means providing a sliding drive connection between the front end plug and the drive means, one member of the front end plug and the drive means being mounted for axial reciprocal movement in the barrel, means resiliently urging the one member forwardly in the barrel, means on the barrel providing rearwardly opening internal notches, lug means projecting outwardly from the one member and removably received in the notches for securing the rear end plug in respective locked and unlocked rotational positions, a key ejector axially reciprocally movable in the barrel between the front end plu
Abstract: A releasable, reusable, slip-on she-bolt type gripper device designed for telescopic reception therein of one end of a cylindrical horizontally extending tie rod which is associated with a concrete wall form and serves to lateral displacement of the sides of the form when the latter is in use. The device is adapted to receive the reaction pull of the tie rod when the latter is under tension as a result of the pouring of wet concrete between the form sides. Longitudinally shiftable, chuck-forming jaw segments within the forward or inner frusto-conical end section of an elongated tubular shell are spring-biased so as frictionally to engage the adjacent end of the associated tie rod and are self-energized by the longitudinal pull of the latter. A pull rod is connected in common to all of the jaw segments, projects rearwardly through the rear or outer end of the shell and, when pulled rearwardly, releases the jaw segments from the tie rod.
Abstract: A releasable, reusable, slip-on, she-bolt type gripper device designed for telescopic reception therein or therethrough of one of the projecting end regions of a cylindrical horizontally extending tie rod as used in connection with a concrete wall form or the like and adapted to receive the reaction pull of the tie rod incident to the pouring of wet concrete between the wall form sides. The device embodies a series of circumferentially arranged chuck-forming jaws which normally grip the adjacent tie rod end region but which become released therefrom when a hollow pull rod through which said tie rod end region extends is actuated.
Abstract: A filing cabinet lock including a generally elliptical barrel having a cylindrical longitudinal plug-receiving bore is provided with a key plug assembly of the spring-pressed plate tumbler type rotatable in the bore and adapted for cooperation with a single-bitted key. First and second slots are provided in the barrel along the bore, for reception of the tumbler ends projecting from the plug assembly when locked and during unlocking, respectively. The outer end of the first slot and a portion of the outer end of the second slot are covered by a plug head in the assembly, and the remaining portion of the outer end of the second slot is covered by a cover member mounted on the barrel, whereby access to the slots from outside of the barrel is prevented.
Abstract: A foundry mold conveyor system for the intermittent movement or indexing of pallets or other mold carriers successively first past a mold receiving station where a foundry sand mold is placed on each empty pallet, then to and through a jacket transfer station where a conventional jacket is placed on each palletized mold, then past a pouring station where each palletized and jacketed mold is poured with molten metal, then back to and through the jacket transfer station where the jacket is lifted from each poured palletized and jacketed mold, then past a mold discharge station where the poured mold is pushed from each pallet, and finally back through the mold receiving station where a fresh sand mold is again placed on each empty pallet.
Abstract: An armored cable-type lock assembly embodying an armored cable consisting of a length of stranded steel cable on which there are threaded in bead-like fashion armor pieces in the form of alternately arranged ball members and socket members. A fixed terminal lock housing at the proximate end of the cable is provided with a transverse bore through which the distal end of the cable may be passed so that the housing functions as an overlap slip joint and causes the cable to form a closed retaining loop when the distal end of the cable is in the bore, the size of such loop being regulated by pulling or pushing the cable through the housing.
