Abstract: A roofing shingle consisting of an upper layer of composition roofing material, a lower layer of waterproof roofing felt, and an intermediate layer spacing the upper and lower layers apart, all of the layers being firmly bonded together. The intermediate layer may function to provide a dead-air space for purposes of heat insulation, or may consist of tubular members permitting free circulation of air between the upper and lower layers. The composite structure of the shingle gives it a bending strength highly resistant to curling or other damage by high wind, and the lower layer may be extended to underlie adjacent shingles in the same course, so as to provide a waterproof under-layer for the upper layers.

Abstract: A dump truck bed including a tiltable dump bucket adapted to dump its load laterally of the bed, and mechanism operable to elevate it to any desired elevation within a substantial range before dumping, whereby its load may be dumped into high truck beds or other higher receptacles, and to move said bucket laterally of the bed in the direction of dumping, whereby its load may be dumped into receptacles further from the side of the bed.

Abstract: In a food delivery system for restaurants, a conveyor tray adapted to receive a food container and to move along an overhead conveyor track from a central station along a loop including a series of delivery stations at patrons tables, an elevator including an elevator tray at each of the stations, trip mechanism at each station operable when actuated to remove the food container from the conveyor tray to the elevator tray at the station, the trip mechanisms being selectively actuated from a central location, mechanism operable by the reception of the food container on the elevator tray to lower said elevator tray to a position within reach of the patron, and to reset the trip mechanism, and mechanism operable by removal of the food container from the elevator tray to re-elevate the tray into operative relation with the conveyor.

Abstract: A phonograph turntable adapted to allow the playing of a plurality of records in automatic sequence, but in which no record ever touches any other record or any other element in relation to which it has a relative movement, excepting of course the stylus of the tone arm. Generally, this object is accomplished by providing each record with its own individual turntable, and handling the turntables in a manner similar to that in which the records themselves are handled in prior automatic record changers.

Abstract: A floor furnace heating system including a specially constructed floor furnace adapted to discharge heated air at floor level with a strong radially outward motion component so as to spread horizontally over most of the room area before rising due to its lowered density, the cold air returns to the furnace also being disposed to assist in this spreading of the heated air at lower levels of the room.

Abstract: An apparatus for balancing automotive wheels consisting of a horizontal support plate adapted to be disposed beneath the central wheel disc, a flexible cable affixed to the support plate to extend upwardly through the central hub aperture of the wheel disc, apparatus for centering the wheel accurately concentrically with the cable, and a gauge member fixed to the support plate and having an aperture spaced above and concentric with the attachment of the cable to the plate, the cable extending through the aperture and being suspended from a higher point to support the wheel, a balanced condition being indicated when the cable is centered in the aperture.

Abstract: In combination with the barrel of a shotgun, a sighting rib extending along said barrel thereabove, and pivoted to said barrel at its rearward end on a horizontal transverse axis, and one or more short links extending angularly between the barrel and rib at their forward ends, the links being both pivoted and longitudinally slidable relative to the rib and barrel to permit changing of their angularity adjust of the angularity of the rib to the barrel, and mechanism for securing one end of each link against pivotal and sliding movement, whereby the angularity of the rib to the barrel may be fixed as desired, while leaving the opposite end of each link freely slidable to permit unequal longitudinal thermal expansion of the rib and barrel.

Abstract: An auxiliary footrest for automobiles consisting of a step rigidly affixed to the automobile body directly adjacent and to the right of the accelerator pedal, at an elevation higher than the normal elevation of the pedal, and adapted to support the right foot of the driver when it is not on the pedal, as is often necessary in cars equipped with automatic speed regulating devices. A skirt attached to the step edge adjacent the accelerator pedal and depending below said pedal may be used as a guide to direct the driver's foot to and from the footrest.

Abstract: A lawn bag caddy consisting of an open wire frame adapted to be inserted snugly into the mouth of a lawn bag to hold the mouth open, the frame being adjustable in circumference to accomodate bags having different circumferences, and a stand operable to support the frame in a generally vertical plane when rested on the ground, the stand and frame being foldable to a substantially flat configuration for convenience of storage.
