UNITED STATES PATENT OFFICE.
CHARLES HENRY LISTER, OF NORTH ST. PAUL, MINNESOTA.
INGLINED ELEVATOR.
Application filed May 8, 1919.
To all whom it may concern:
Be it known that I, CHARLES HENRY LIS- TnR,'a citizen of the United States, residing at North St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Inclined Elevators, of which the following is a specification.
My invention relates to improvements in inclined elevators and is particularly adapted for use on such elevators where boxes or packages are delivered to the same automatically from a gravity conveyer as illustrated in my Patent No. 1,200,508 of October 10, 1916.
It is the design of such devices to deliver 7 packages or boxes from a gravity conveyer in front of the push bars of the elevator but occasionally a package is improperly delivered and deposited upon the bar to the detriment of the operation of the device.
The object of my present invention is to prevent such defective delivery of boxes or packages to the inclined elevator from the gravity conveyer and to minimize possible injury to the goods by reason of improper placing of the packages on the elevator.
In the accompanying drawings Figure 1 is a side view of my improvement partly in section; Fig. 2 i a plan of the same and Fig. 3 is a fragmentary view showing one of the elevator bars.
Referring to the drawing, A is the delivery end of a gravity carrier of any ordinary construction and B is the receiving end of an inclined elevator such as that illustrated in my above mentioned Patent No. 1,200,508. A is usual in such structures, the elevator is provided with a power driven endless chain conveyer 10 having a series of push bars 11 connected at their ends to the chains 12 of said conveyer 10. The purpose of such bars 11 is, of course, to push the packages or boxes up the inclined elevator.
My improvement consists of the following described mechanism embodied in such an elevator. The push bars 11 are journaled at each end in flanges 13 on the side chains 12 of the elevator carrier and are preferably angular in cross section 2'. 6., as shown in the drawings, hexagonal. On one end of each cross bar 11, a pinion 14: is fixed which is adapted to mesh with a gear rack 15 attached to the side frame 16 of the elevator Specification of Letters Patent.

Serial No. 295,562.
near its base. Except when said cross bars 11 pass this rack, they operate merely as the propelling or supporting members of the conveyer on the inclined elevator but when in the travel of the conveyer 10 a bar reaches said rack 15 and a pinion 14: engages the same the bars are rotated in a direction opposite to that in which the carrier chainis traveling and in consequence if, as sometimes occurs, a box or package is delivered from thegravity carrier A to the elevator in such position that it will ride upon a cross bar, such package is pushed backward and slips from the bar upon which it has been delivered to the floor of the elevator in position to be pushed up the same by the succeeding bar on the elevator conveyer.
Having described my invention, What I claim as new and desire to protect by Letters Patent is:
1. The combination with the conveyer of an inclined elevator of push bars journaled at their ends in said conveyer and a pinion on one end of each said bars and a gear rack, fixed .on the side frame of said elevator near its base, adapted to engage said pinions and turn the push bars as they pass said rack to prevent the accidental retention of packages upon said bars.
2. The combination with the conveyer of an inclined elevator of a series of push bars journaled at their ends in flanges attached to said conveyer, a pinion on one end of each bar and a gear rack fixed on the side frame of said elevator and adapted to temporarily engage and rotate said push bars as they pass said rack, whereby a package deposited upon a bar may be dropped in front of the succeeding bar.
3. In combination with the power driven conveyer of an elevator, a series of push bars journaled at their ends in said conveyer, a pinion on each of said bars, and a gear rack attached to the frame of said elevator and adapted to engage said pinion and rotate said bars as they severally pass said rack, whereby packages misplaced upon said bars may be removed therefrom.
In testimony whereof I have signed my name to this specification in the presence of a subscribing witness.
CHARLES HENRY LISTER.
