Description
THGMAS KERRIGAN, 0F MAHANOY PLANE, PENNSYLVANIA.
SHAKER-PLATE Specification of Letters Patent.
Patented Dec. 21, 1915.
Application f led March 27, 1915. Serial No. 17,456.
To all whom it may concern:
Be it known that I, THOMAS KnRRIoAN, a citizen of the United States, residing at Mahanoy Plane, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Shaker-Plate, of which the following is a specification.
The device forming the subject matter of this application is a shaker, or screen, and the primary object of the invention is to provide means whereby shaker plates may be assembled with the frame without bolting through the shaker plates, the construction being such that the shaker nlatesmay here moved readily at the will of operator.
.115 is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.
With the above and other obj ectsin view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawing: Figure 1 is a top plan; Fig. 2 is a section on the line of Fig. 1; Fig. 3 is a cross section on the line 33 of Fig. 1; Fig. 41: is a cross tion on the line 4- 1 of Fig. 1. V
In carrying out the present invention there is provided a frame comprising sides 1 and an end wall 2. Located below the end 2 and constituting to all intents and and Ti'illl an purposes a part thereof is an end bar 3 having an upstanding flange l located in front of the end wall 2 and defining a recess. EX- tended between the sides 1 is an intermediate bar 5 provided in its upper face with a groove defining upstanding flanges 7. 'The sides 1 of the screen frame are united at their forward ends by a front bar 8 carrying an upstanding flange 9. Assembled in any suitable manner with the forward end of the frame is a chute 10, constructed as the eXigencies of the proposed use may demand. The screen frame above described may be mounted in various ways, hangers 11 being resorted to if desired. Extended longitudinally of the frame and cooperating with the sides 9 are supports 12 in the form of beams.
The screens or shaker plates 14 may be variously constructed so far as their screening functions are concerned, but at their inner ends they are provided with depending lips 15 formed by bending down the ends of the shaker plates, the lips 15 lying between the flanges 7 of the intermediate bar 5 and being received in the groove 6 thereof as Fig. 2 will clearly show. The forward and rear or outer ends of the shaker plates 14 are equipped with depending lips 16, lying, respectively, to the rear of the flange r on the end bar 8 and in front of the flange 9 on the front bar 8 It will be understood from the foregoing description that owing to the particular manner in which the lips 15 and 16 of the shaker plates 14 interlock with the various cross bars, an endwise movement of the shaker plates will be prevented. Transversely, the shaker plates are supported by the cross bars 8, 6 and 3, and longitudinally, the shaker plates are upheld by the supports 12 which are assernbled withthe sides 1 of the main frame.
Disposed above the shaker plates and bearing thereon are retainers 17 in the form of bars extended loi'igitudinally of the main frame and abutting against the sides 1. Transverse securing devices 18, preferably bolts, pass through the openings 17 in the retainers 17 and through openings 19 formed in the sides 1, these openings being enlarged vertically so as to permit a slight vertical movement of the retainers 17 with respect to the shaker plates 1ft. The securing devices 18 may carry nuts 20, hearing on the outer faces of the sides 1 of the main frame. The retainers 17 bear upon the shaker plates 14 adjacent the longitudinal edges of the shaker plates and bind the shaker plates against the supports 12. A means is provided for forcing the retainers 17 downwardly on the shaker plates 14:, to bind the latter on the supports 12, and with this end in view, angle brackets 21 are secured to the sides 1 of the main frame, the angle brackets comprising arms 22 which overhang the shaker plates 14. Clamping devices which may be screws 23 are mounted in the arms 22 of the angle brackets 21 and bear upon the retainers 17, the screws 23 if desired being provided with lock nuts 24 which coact with the overhanging arms 22 of the angle brackets 21. As shown best in Figs. and 4, the retainers 17 may be provided with depending projections in the form of pins 25 received in openings 26 formed in the supports 12. As will be understood readily, when the screws 23 are rotated to cause the same to move upwardly, and when the securing devices or bolts 18 are detached, the retainers 17 may be lifted, whereupon the depending flanges or lips 15 and 16 on the ends of the shaker plates 14 may be disengaged respectively from the cross bars 6 and 8. Since the transverse securing devices or bolts 18 are mounted for vertical movement in the enlarged openings 19 of the sides 1, the retainers l7 first may be crowded down onto the shaker plates 1% by means of the screws 23, after which the nuts 20 on the securing bolts 18 may be tightened up. Owing to the construction above described, a strong and a double hold for the retainers 17 on the longitudinal edges of the shaker plates lt is provided. Since the projecting pins 25 on the retainers 17 engage in the openings 26 of the supports 12 and since, as shown in the drawing,
the pins 25 pass through the shaker plates 14:, all of the parts above mentioned are interlocked.
Having thus described the invention, what is claimed is In a device of the class described, a frame embodying sides having vertically elongated slots; supports connected with the sides; a screen resting on the supports; retainers resting on the screen and provided with transverse openings, the retainers being united with the supports by a pin and open- 1 ing union to prevent a longitudinal movement of the retainers, to prevent a longitudinal movement of the screen and to aline the openings in the retainers with the slots; vertically movable clamping devices carried by the sides and coacting with the retainers to force the retainers onto the screen and to force the screen on the supports; and transverse clamping devices mounted in the openings of the retainers and vertically movable in the slots of the sides when the vertically movable clamping devices are actuated, the transverse clamping devices being adapted to be tightened up, thereby to bind the retainers on the sides and to divide the strain between the vertically movable clamping devices and the transversely movable clamping devices' In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
THOMAS KERRIGAN.
