DOOR FOR PACKING-HOUSES.
Specification of Letters Patent.
Patented May 13, 191.3.
Application filed May'22, 1912. Serial No. 699,012.
To all whom it may concern Be it known that I, BERNARD Barns, citizen of Canada, residing at Vancouver, Province of British Columbia, Canada, have invented certain new and useful Improvements in Doors for Packing-I'Iouscs, of which the following is a specification.
My invention has for its object the provision of means whereby when the door of the cooling room of a packing house is opened, the closure for the trolley passage will be automatically and simultaneously moved to an open position to permit the passage of the meat-carrying trolley.
The invention also seeks to accomplish the stated object by means which will be at once simple and durable, so that the cost of installation and maintenance will be slight and the liability of the parts to get out of order will be minimized.
The invention is illustrated in the accompanying drawings, and consists in certain novel features which will be hereinafter first fully described and then particularly pointed out in the appended claims.
In the drawings :-Figure 1 is an elevation of a packing house door having my invention applied thereto; Fig. 2 is a detail section 011 the line 22 of Fig. 1, showing the trolley closure in the closed position in full lines, and in the open position in dotted lines; Fig. 3 is a detail perspective view of one of the brackets or supports employed for the operating mechanism; and Fig. 4 is a detail perspective view of parts of the operating mechanism, showing the same detached.
The door, 1, is of the usual refrigerator construction and is mounted upon hinges, indicated at 2, and equipped with a lock, indicated at 3, of such character that the door will normally be in closed position and will form an airtight engagement with the door frame, these features being well-known in the construction of refrigerator buildings. Above the .door 1, is a rail or track 1 supported in the building in the usual manner and so located that the door 1 will swing freely below the rail without binding against the same, but will not be so far below the rail as to leave an opening through which the cold air may escape or hot air enter the cooling room in such quantities as to affect the meat or other products stored therein. Trolleys are mounted to travel on this track, and as the trolleys are of ordinary construction and their use is well-known, I have deemed it unnecessary to illustrate the same and have omitted them from the drawings, therefore, for the sake of clearness. An opening 5 is provided above the door 1 through the door frame to permit the passage of the trolley when moving articles from the cooling room, and this trolley opening or passage is fitted with a door or closure 6.
On the door frame, above the trolley passage 5, I secure brackets 7, consisting of a base plate 8 adapted to fit against the frame, and an arm 5) extending from the base plate and constructed with an opening 10 near its free end. A shaft 11 is mounted in the openings '10 to rotate therein, and between the brackets 7 similar brackets 12 are secured to the said shaft by set-screws 11.3, the base plates of these brackets being secured to the door or closure (3 at the upper end of the same, as clearly shown, whereby rotation of the shaft will swing the door in a vertical plane, as will be readily understood on reference to the full lines and the dotted lines in Fig. 2. The shaft: 11. extends laterally from the door (3 and is equipped at its outer end with a bevel pinion 14; meshing with a similar pinion 15 on the upper end of a shaft 16 which is journaled in brackets 17 on the door frame, the said vertical shaft 16 being disposed in the same vertical plane as the pivotal members of the hinges 2. The shaft 16 is constructed at its lower end with a crank arm 18 having its tern'linal bent downwardly, as shown at 19, to engage a bracket 20 secured on the door 1 at the upper edge of the same and near the corner thereof. This bracket or guide 20 is in the form of a channel iron, as shown most clearly in Fig. st, whereby it presents a groove or trough in which the down-turned terminal 19 of the vertical crank shaft may play.
The constrimtion and arrangement of the several parts of the device being thus made known, .it is thought the operation and advantages of the same will be readily understood and appreciated.
\V hen the door 1 opened to permit the withdrawal from the cooling room of a loa d of meat or other products, the guide or trough 20 necessarily follows the movement of the door, and the terminal 19 engaging said guide will, of course, be carried forwardly and around therewith, so that the shaft 16 will be rotated, and this rotation will be imparted through the bevel pinions 15 and 14 to the shaft 11, so that the door 6 carried by said shaft and rigid therewith will be swung to the position shown in dotted lines in Fig. 2, out of the way of the trolley which may then roll or travel upon the track or rail 4 without hindrance. As the door 1 is closed. after the meat has been withdrawn,the several parts will move in the reverse direction to swing the closure 6 to the position shown in full lines in Fig. 2, as will be readily understood.
My device is obviously simple in the construction and arrangement of itsparts, and will be found highly efficient for the purposes for which it is designed. The troughlike guide 20 permits relative movement of the terminal 19 and the said trough, so that binding of the parts will not occur, and the frictional wear will not be excessive. As the trolley passage will be uncovered automatically, no attention thereto will be required of the operator, loss of time in withdrawing the meat or other product will be avoided, and the exposure of the cooling room to the entrance of outside hot air for a prolonged period will be prevented.
It is the common practice to mount the doors 1 upon spring-hinges, so that they will tend to automatically close after having been opened, and my device accelerates this operation, and, in some instances, may dispense with the springs in the hinges, as the weight of the closure 6 tends to hold it in its closed position, so that when it is swung outwardly and upwardly it will remain in such position only while the main door is held open and will gravitate at once to its original closed position when the main door is relieved of the holding force.-
Having thus described my invention, what I claim is 1. In a door for packing houses, the'combination with a door frame having a trolley passage therethrough, of a main door hung on said frame below said trolley passage, a supplemental door adapted to close the said trolley passage, a rotary shaft mounted on the door frame and connected with said closure for the trolley passage, a rotary shaft mounted on the door frame in a plane intersecting the plane of the first-mentioned shaft and having a late-rally extending crank arm at its lower end engaging the main door, and gearing between the adjacent ends of the two shafts.
2. In a door for packing houses, the combination of a door frame, a main door hung on said frame, a supplemental closure above the said door, a rotary shaft supported on the door frame above said closure and having rigid connections therewith, a crank shaft mounted on the door frame above the main door and extending laterally from the supplemental closure, gearing between the two shafts, and a guiding bracket secured on the main door at the upper end thereof and engaging the said crank shaft whereby the opening or closing of the main door will actuate said shaft.
In testimony whereof I affix my signature in presence of two witnesses.
