PUSHING APPARATUS Filed May 16, 1928 Patented Sept. 17, 1929 UNITED STATES PATENT OFFICE PUSHING APPARATUS Application filed May 16,
This invention relates in general to apparatus for pushing objects along a predetermined path, and more particularly to such apparatus for pushing a plurality of cakes or blocks of ice along the floor of an ice house.
In ice manufacturing plants the fakes or blocks of ice as they are ejected from the cans are arranged in a row on the floor against a bumper rail on one wall of the house toward which the floor declines and in which there is a discharge opening, and the blocks are carried on an endless conveyor along said floor and bumper rail to said opening through which they slide outwardly by gravii y.
One object of my invention is to provide power oierated apparatus of the character described embodying novel and improved features of construction for simultaneously pushing all of a plurality of such blocks of ice alon said floor so that the blocks are always arranged in immediate succession in a row with one always ready to be ejected through said opening.
Another object is to provide a novel and improved pushing apparatus including a pusher arranged to run on a track and driven by a motor mounted on the pusher and geared to a straight rack whereby great traction and power are obtained.
Other objects are to provide a pushing apparatus of this character including means for automatically reversing the direction of movement of the pusher and stopping the same: to provide such apparatus which shall be siuu'ile. inexpensive and reliable in construction and operation, and to obtain other advantages and results as may be brought out by the following description.
Referring to the accon'ipanying drawings. in which corresponding and like parts are designated throughout the several views by the same reference characters,
Figure 1 is a top plan view of a pushing apparatus embodying my invention.
Figure 2 is a transverse vertical sectional View taken on the line 2-2 of Figure 1.
Figure 3 is a transverse vertical sectional view taken on the line of Figure 1 Figure 4r. is a fragmentary horizontal sec- 1928. Serial No. 278,230.
tional view taken on the line 4-4 of Figure 3, and
Figure 5 is a wiring diagram.
Specifically describing the illustrated embodiment of the invention, the reference char- 5.; acter A. designates the floor of an ice house or the like which gradually declines toward a wall B upon which is arranged a horizontal bumper beam C against which blocks or cakes of ice D are arranged in a row as the cakes are ejected from the freezing cans. The wall B has an opening E therein through which the blocks or cakes of ice D are passed into an adjacent room or platform. The construction so far described is old and no claim of novelty thereon is made.
My pushing apparatus includes a pusher 1, which has side flanges 2 and 3; one of which depends through a slot 4 in the floor A. Each of these flanges has journalled thereon a pair of wheels 40 arranged to run on a rail' 5 which may be conveniently mounted on an I-beam (3, to provide the required stability. The rails 5 are arranged substantially parallel to the bumper beam C and beneath the floor A so that the pusher l is arranged to move parallel to the bumper beam C toward and from the opening E in the wall B.
For automatically moving the pusher along said tracks I may utilize a reversible electric motor 7 secured to the top of the pusher and connected by a chain and sprocket gearing 8 to the shaft 9 of a speed reducing gear mechanism 10 of known construction. This speed reducing mechanism is also mounted on top of the pusher 1 and has a driving shaft ll extending downwardly verticaland journalled in a bearing 12 secured in a bracket 13 to the inside of the flange 3 of the pusher. The shaft also has fast mounted thereon a pinion 14 meshing with a rack bar 15 secured to the web of the I beam 6. The speed reducing gear mechanism 10 causes the shaft 11 to be driven at a relatively slow speed and obviously rotation of the shaft 11 due to meshing of the pinion=14 and rack bar 15 will cause movement of the pusher along the rails 5.
In operation of the apparatus tl e'. pusher is nermally disposed atthe end of the row of mil blocks D of ice opposite the opening E, and when the motor 7 is started the pusher moves the blocks of ice toward the opening E. As each block reaches the opening, it immediately slides therethrough due to the inclination of the floor A, and accordingly the blocks are successively ejected through the opening upon continued movement of the pusher in the same direction.
Preferably means is provided for automatically reversing the direction of movement of the pusher when it reaches the opening E. This means may comprise a reversing switch 16 of known construction mounted upon the top of the pusher and including an operating shaft 17 upon one end of which is a depending arm 19 to cooperate with spaced abutments 20 and 21 disposed upon the corresponding I-beam 6, one of the abutments being adjacent the opening and the other being disposed at the opposite end of the path of movement of the pusher. \Vhen the pusher reaches the opening E, the arm 19 strikes the abutment 20 which actuates the switch 6 to reverse the current through the motor 7 and when the pusher reaches the other end of its path of movement the arm 19 strikes the other abutment 21 so as to throw the switch into reverse position. At the same time a cam F on the pusher 1 will operate a normally closed stationary stop switch G cutting off the current and thereby bringing the apparatus to a stop. To start the pusher in the other direction toward the opening E, the operator presses a conveniently located push button switch H, thereby closing the circuit.
The shaft 11 is preferably formed with a reduced portion 22 so that the shaft 11 will break at that point should the pinion am on the rack or the ice cake-s become obstructed or jammed in the opening E.
\Vhile I have shown and described the in- "ention as embodying certain details of construction, it will be understood that this is primarily for the purpose of illustrating the principles of the invention, and that many modifications and changes may be made in the details of construction without departing from the spirit or scope of the invention.
