ATANK SPLASH PLATE Filed June 24 1929 Patented May 16, 1933 UNITED STATES PATENT OFFICE FREDERICK G. THWAITS, OF WAUWATOSA, WISCONSIN, ASSIGNOR TO 'THE HE'IL CO., OF
MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN v TANK SPLASHl PLATE Application led June 24,
The object of the present invention is to provide tank splash plates for tank truc-ks used in carrying oil, gasoline and other liquids.
A further object of the invention is to pro- Vide a tank splash plate for tank trucks which will minimize the shock of the weight of the moving liquid in starting and stopping the truck and in turning corners as well as the wear and strain on the trucks, parts and tires.
A further obj ect of the invention is to provide tank splash plates which are attached to their supports in a manner to permit slight turning movement thereon when subjected to strain to eliminate the strain being transferred to the supporting members and loosening of said supports from the partitions and heads.
With the above and other objects in view the invention relates to the improved splash plates for tank trucks and their parts and combinations as set forth in the claims, and all equivalents thereof.
Referring to the annexed drawing in which the same reference characters indicate the same parts in all of the views:
Fig. 1 is a transverse vertical sectional view of a tank equipped with the preferred form of my invention;
Fig. 2 is a longitudinal sectional view thereof;
Fig. 3 is a view similar to Fig. 1 showing a modified form of my device;
Fig. 4 is a view similar to Fig. 2 vshowing the same modification.
In the form shown in Figs. 1 and 2 the reference numeral 1 designates the usual tank, which in the present instance, is divided into transverse compartments 3 by partitions 2. Welded to the face of each partition and also to each end wall of the tank is a pair of parallel angle irons 4 and extending longitudinally of the compartments and' bolted to the angle irons is a pair of longitudinal angle iron supporting members 5. Welded to each pair of angle irons and suspended within each compartment is a splash plate 6 which is longitudinally curved to present a convex face towards one side of the tank and a concave 1929.` Serial Noi. 373,174.
surface towards `the lother side of the tank.
rIhe upper and lower edges of the splash plate terminate short of the upper and lower surfaces of the tank.V The bolts connectingthe irons together are positioned' in vertical alinement in pairs to permit a slight turningof the ends of the longitudinal angle irons on the bolts when the plates are subjected to strain causing slight distortion thereof, thus eliminating twisting of the parallel'irons 4. j
With this construction, it will be observed that the splashor baffle-plate 6 will resist the movement of liquid (caused by the swinging and jouncing of the vehicle) toward opposite sides of the tank, but this resistance to the movement of the liquid will not be abrupt and positive, as the curved faces of the plate will cause the liquid to slide off the edges of the plate. As it moves or splashes against the convex side of the plate, the liquid will be caused to move in a curved path over the top edge as well as over the lower edge of the plate, and practically the same actionwilltake place on the concaved side of the plate, so that the plate will thereby be relieved of the impact or force of the movement of the liquid to a large extent. In actual practice, these curved plates will serve to greatly reduce the churning of the liquid during transportation and will also reduce injury to the tank to a minimum. It has also been found in actual practice that making the plates curved to present a convex surface toward one side and a concave surface toward the other side so greatly reduces the force of the impact or push of the liquid that the liability to breakage of the plates from their supports is greatly reduced.
In the modified form of device, the plates are arranged transversely of the tank, this form of device being particularly desirable where the tank is not provide-d with transverse partitions. In some cases, I may arrange in the same tank transverse as well as longitudinal splash-plates.
What is claimed as new is 1. A splash plate structure for tanks, comprising, horizontally alined upper flanges projecting inwardly from the opposite walls of the tank, horizontally alined lower flanges projecting` inwardly from said opposite tank walls and cooperating with said upper flanges to provide superimposed sets, an upper supporting bar resting upon said upper flanges, a lower` supporting bar resting upon said lower flanges, alined retaining bolts e'oacting with each set` of said flanges and with the adjacent bar ends, and a splash plate' attached 2. A splash platestructure for tanks, comprising, horizontally alined parallel upper flanges projecting inwardly fromv the opp'oLA site walls of a tank, horizontally alined parallel lower flanges projecting' inwardly from' said opposite tank walls and cooperating with upper flanges to provide vertically superimposed sets, upper and lower parallel supporting b'ar's resting' upon said upper and lower' flanges respeetivelyalined retaining bolts `t'iir'ria'lo'ly connecting the corresponding ends of saidrb'ars with each set'of said flanges, and splash plate attached to both of said bars' andI eXten'ding upwardly' and downwardly beyond the saine.
