PRERINSE DEFLECTOR Filed Sept. 16, 1929 INVENTOR 9m iMm@.-4%w M? v Patented Oct. 6, 1931 UNITED STATES PATENT OFFICE WISCONSIN VIRGINIA, ASSIGNOR TO GEO. J'. WISCONSIN, A CORPORATION OF PRERIN SE DEFLECTOR I Application filed September 16, 1929 Serial No. 393,103.

This invention has for its object to provide a pre-rinse deflector for bottle-washing machines.

Bottle-washing machines provided with a pie-rinsing device such as that shown in the co-pending application of George L. N. Meyer and Otto Dreher, Serial No. 309,302, filed September 29, 1928, wherein bottles are subjected to an emptying and preliminary l0 rinsing before loading onto the conveyor 0f the washing machine, have been handicapped by the necessity for use of 'low water pressure in the pre-rinsing device in order to avoid a drenching of the operator in the absence of a bottle in any one of the grooves ortroughs forming bottle seats of the swinging table. The present invention provides an automatic guard member for each of said bottle seats adapted to recede out of the way from the weight of the bottle when the bottle is present but springing into position'to intercept the forceful stream of rinsing water and de fleeting it away from the direction of the operator and into the drain tank therebeneath, thus making it possible to use a rinsing pressure as strong as desired.

While the invention is particularly designed for use with such pre-rinsing devices, it is capable of use with other devices and is .therefore not limited to pro-rinse loaders.

lVith the above and otherobjeets in view the invention consists infrhe deflector as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views,

Fig. 1 is a sectional view of a portion of a pre-rinse device provided with a deflector constructed in accordance with this invention and showing the position of parts when a bottle is in place and receiving the pre-rinsing spray;

Fig. 2 is a similar view showing the de- 5 flector raised to deflect the pro-rinsing spray in the absence of a bottle;

Fig. 3 is an enlarged sectional view of the deflector;

Fig. 4 is a sectional view line 44 of Fig. l;

on the plane of Fig. 5 is a sectional view on the plane of line 55 of Fig. 2, and

Fig. 6 is a longitudinal sectional view of a deflector of modified form.

In these drawings, 10 indicates a rinsing 555 tank, or drain trough into which the bottles are emptied when the swinging frame 11 is tilted from a horizontal position to the posi tion shown. An automatic valve-controlled spray pipe 13 is in position to discharge forceful sprays of water through openings in the wall of the drain tank 10 so that the sprays enter the bottles which are carried in the respective grooves or bottle seats of the corrugated sheet metal plate 14 forming the sup- 5 porting surface of the swinging table. The

direction of the streams of rinse water is toward the operator, who places the empty bottles on a feed table 15 above the drain tank. As previously used the pressure in the spray pipe 13 has been limited to avoid spraying the operator in the absence of a bottle on one of the bottle seats of the swinging table and to prevent this a spring-actuated deflector 16 is provided for each of the bottle 7 seats, there being an opening formed in the corrugated sheet metal plate 14 into which the deflector is depressed by the weight of the bottle, but which deflector in its open position, as when no bottle is in place thereon, so stands in the path of the stream of water and deflects it away from the operator and into the drain trough therebeneath.

This deflector may consist of a sheet metal plate bent to conform with the rounded suras face of the bottle seat, as shown in Fig. 4, and therefore offering no obstruction to the passage of the bottle in the horizontal position of the swinging table. It is preferably provided with side wings 17 bent downwardly on parallel to each other. The deflector is pivotal ly mounted at its upper end by a pivot pin 18 passing through the side wings 17 and journaled in brackets 19 secured to the upper angle 20 of the swinging table 11. as Preferably the deflector is soldered or otherwise rigidly mounted on the pivot pin and the end of the pivot pin, as seen in Figs. 4 and 5,

is bent downwardly to form a crank arm 21, WlllCll is engaged by a c011 spring 22 secured to the lower angle 23 of the swinging table. The arm 21 may have suflicient weight to dispense with the necessity for a spring.

The upper position of the deflector is limited by the engagement of outturned lugs 24 on the edge of the side wings 17 with the bottom of the bottle seat 14, while the lower position of the deflector is determined by its engagement with the lower angle 23, the side wings being shorter to leave a projection 25 of the curved surface for that purpose.

At the upper end of the deflector there is I preferably a downwardly extending end wall will do no harm.

26 curved around the pivot pin to deflect the water downwardly, but, if desired, such wall may be continued to the end of the side wings to form a bottom wall 27, as shown in Fig. 6.

\Vith a deflector of this character on each of the bottle seats and with a spray pressure as strong as desired for the intended purpose, thereis no danger of the operator being deluged with water every time an operation takes place in the absence of a bottle on one of the bottle seats, for the deflector stands in position to intercept the stream and deflect it downwardly into the drain trough, where it This is accomplished without interfering in any way with the movement of the bottles to and from the bottle seats, since the force of the spring is such that it will be easily overcome by the weight of the bottle on the deflector.

What I claim as new and desire to secure by Letters Patent is:

1. In a pre-rinse device or the like, a tilting table over which the bottles slide grooved to form bottle seats, means for directing a rinsing spray thereon, a deflector on each bottle seat for intercepting the rinsing spray thereto and capable of being depressed outof position by the weight of a bottle thereon. 2 In a pre-rinse device or the like, a swinging table having bottle seats in the 'form of grooves over which the bottles slide,

spray means for forcefully ejecting rinse water against the bottle seats when the table is swung to the rinsing position, and a swinging deflector mounted on each bottle seat for lntercepting the water spray thereto in the absence ofa bottle on the bottle seat, said deflector being depressed out of position by the weight of a bottle thereon.

3. A pre-rin'se device or the like having a swinging table over which the bottles slide containing grooves forming bottle seats with openings in their bottoms andhaving a spray means for forcefully e'ecting rinse water toward the bottle seats w en the swinging table is in an inclined position, a deflector let into the opening in the bottom of each bottle seat and depressed by the weight of a bottle thereon, and means for lifting the deflector to a position for intercepting the stop lugs on the side wings engagin ing spray means for forcibly discharging water toward the bottle seats in the rinsing position of the table, each bottle seat having an opening in the bottom thereof, a deflector pivotally mounted beneath each bottle seat and occupyin the space formed by said opening, said deflector having side wings with stop lugs for engaging the edges of the opening, and spring means for swinging the deflector to deflecting position.

5. In a pre-rinse device or the like having a swinging table with bottle seats and having spray means for forcibly discharging water toward the bottle seats in the rinsing position of the table, said swinging table having a corrugated sheet metal plate mounted on parallel spaced angles with an opening in the bottom of each bottle seat between the angles, brackets secured to one of the angles, a pivot pin pivotally mounted in the brackets, a deflector occupying the space formed by the opening in the bottom of the bottle seat, parallel side wings thereon in which the pivot pin is mounted, stop lugs on the side wings engaging the edges of the opening, an end of the deflector projecting beyond the side wings and engaging the other one of said angles, an arm on the pivot pin, a spring connecting the arm with the last mentioned angle, and an end wall connecting the side wings of the deflector and extending around the pivot pin.

6. In a pre-rinse device or the like having ing in the bottom of each bottle seat between the angles, brackets secured to one of the angles, a pivot pin pivotally mounted in the brackets, a deflector occupying the space formed by the openin in thebottom.of the bottle-seat,\para l1e side wings thereon in which the pivot pin is mounted, the

edges of the opening, an end of t de ector projecting beyond the side wings and engaging thepther one of said angles, an arm on the ivot pin, a spring connecting the arm wit the last mentioned angle, and an end wall connecting the side wlngs of the deflector and extending around the pivot pin and continuing to the end of the side wings to form a bottom for the deflector.

In testimony whereof. I affix my signature.
