AUTOMATIC STOP FOR BOTTLE WASHERS.

Original application filed November 22, 1915, Serial No. 62,706. Divided and .this application filed June 9,

' 1919. Serial No. 302,883. 7

To all whom it may concern:

Be it known that I, GEORGE J. MEYER, a citizen of the United States, and res 1dent of Milwaukee, Milwaukee County, Wisconsln, have invented new and useful Improvements in Automatic Stops for Bottle Washers, of

is a description, reference being had to t e accompanying drawings, which are a part of this speclfication.

This invention has for its ob set to provide a bottle washing machine of the type in which the bottle conveyor is given continu ous travellin motion, and the washlng and brushing mec anism is iven a reciprocating travel to co-operate wit the bottles successively while the latter are travelllng, such type of bottle washer beingjexemplified Patent No. 1,095,290 to anlel Schm1 dated May 5,1914.

Another object of the invention is to pro vide a safety stop mechanism whlch W111 automatically disconnect the machine from its driving means upon the occurrence of an abnormal resistance to the operation of the machine from any cause.

Another object of the invention is to perfect details of construction of such a machine generally. I

This application is a continuation and division of, that is contains subject matter taken from, my co-p ending application, Serial No. 62,706, filed Nov. 22, 1915, for

bottle washing machine, which a plicationhas become Patent No. 1,310,128, ated July 15, 1919.

With the above and other objects in view the invention consists in the automatic stop for bottle washers as herein claimed and all equivalents. I

Referring to the accompanying drawings,

- in which like characters of reference indicate cap Fig. 3 is a plan view thereof;

Fig. 4 is a detail view on the plane of line 44 of Fig. 3;

Fig. 5 is a front view of the automatic stop;

Fig. 6 is a side view thereof; and

Fig. 7 is a planview thereof.

Fig. 8 is a rear view of the trip member.

In these drawings 15 indicates a frame in which is journalled a cam shaft 17 having gearing connection with a suitably driven shaft 18. Sprocket wheels 19 on a shaft which is geared to cam shaft 17 give motion to a chain conveyor 20 which passes there- 'around and also around an idle sprocket 21 and another idle sprocket not shown. This chain conveyor has the links of the chain members connected by wooden cross strips 23 forming bottle carriers having tapering openings to receive the necks of bottles so that the bottles are carried thereby in an inverted position. A pair of cross-shaped frames 24 are suspended by links 25, one cross-shaped frame on each side of the frame and together form a vertical slotted swinging guide frame carrying the bottle clamping mechanism and the brushing and rinsing mechanism. This guide frame is reciprocated by having a roller 26 on one of the links 25 travelling in a cam groove of a cam gear 27 on the cam shaft 17, which groove is so shaped as to produce the slow forward and quick return movement of the frame. Slidably mounted in the vertical slots of the frames 24 is a lower clamping frame 28 which is moved vertically in the slots by means of adjustable links 29 connecting it with levers 30, which are pivotall mounted on the frames 24 and are operate by a bell crank lever 31 fulcrumed on the frame 15 and having a roller at one end riding in a cam groove of the cam gear 27. A link 32 at the other end connects it with one of the levers 30. On the lower clamping frame 28 are carried rows of spring-pressed telesco ing sleeves 33 to form yielding funne shaped bottle-mouth-engaging members through which brush spindles 34 pass to enter the bottles, as will be later described. On this frame also are a series of water pipes 35 having funnel-like bottle-mouth-engaging members 36 to fit against the bottles, while jets of water are ejected through openings in the pipes into the interiors of the bottles, there preferably being one of said water pipes ahead of the two rows of brushes, and

two of the water pipes at the rear of, each row of brushes, as shown, so that each bottle will first receive a rinsing, then a preliminary brushing, then a final brushing, followed by a second rinsing and a third rinsing as it travels through the machine.

Also slidably mounted in the vertical guide slots of the movable frames 24 is an upper clamping frame 37 which is lowered at the same time that the lower frame is raised. This movement of the upper clamping frame is produced by adjustable connecting rods 38 connecting it with the shorter ends of levers 30.

The upper clamping frame 37 has a pair of horizontal rods 39 at its ends which form pivotal supports for a number of bottle gage frames 40. These gage frames carry gage members 41 at their ends directly above the brush spindles 34, and have downwardly projecting cam fingers thereon to receive and center the bottoms of the bottlesbetween them and hold the bottles in clamping relation with the yielding funnel-shaped sleeves 33 while the internal scrubbing by means of the brushes on spindles 34 is being performed. The gage frames 40 are releasably held in their normal positions by springpressed clamping jaws 42 thereon engaging the lower surfaces of square clamping rods 43 extending across the clamping frame 37 and ositioned with their diagonals vertical and orizontal. The spring clamps 42 hold the gage frames 40 in their normal positions until they are overcome by an abnormal pressure on the bottles, as upon a brush spindle 34 being lifted against a crowned bottle or a bottle containing a cork or other obstruction. The bottle being lifted by the upward movement of the brush spindles carries the jaws of the spring clamp 42 above the engaged surfaces of the clamping rods 43 and the gage frame is free to swing upwardly to allow the bottle to be lifted without injuring the mechanism. There are as many bottle gage frames 40 as there are bottle openings 1n each of the bottle carriers 23, but any one of them, when raised, will engage and lift a cross bar 44 which is carried by arms 44 pivotally mounted on the rods 39. Arc-shaped cam blades 45 are carried by the cross rods 44 at one end thereof and are adapted to engage arc-shaped cam wings 46 on a trip member 47 which is pivotally mounted at 112 on a vertical axis to lugs on the frame 37. An arm 48 extending from the trip member 47 is bent outwardly and downwardly to engage a trigger 85 of an automatic stop mechanism to stop the operation of the machine whenever said arm is moved by the swinging of the stop member 47 incident to the movement of one of the cam blades 45 against the cam edge of one of the wings 46, shown in Fig. 4, as upon the lifting of one of the bottle gage frames 40 in the manner described. I

In addition to the clamping frames, the vertical slots of the swinging reciprocated frames 24 serve to guide the vertical movements of a gear box 53, in which the tubular brush spindles 34 are journalled, and from which they receive a supply of water under pressure. The ends of the gear box 53 while sliding in the grooves of the guide frames 24 are pivotally mounted on the ends of counterweighted levers 60 which are fulcrumed on upstanding pivoted links 61 which in turn are pivotally mounted on the sides of the frame. The two levers 60 are connected at their outer ends by a counterweight 62 which counterbalances the Weight of the gear box to facilitate the raising and lowering thereof. One of the links 61 has an electric motor 63 mounted thereon, or preferably on a separate pedestal pivotally mounted with the link, and a belt 64 connects said motor with a pulley 65 on the shaft 55' of the gear box for driving the spindles.

A link 66 is mounted on a wrist pin on the cam gear 27 and connects with one arm of a bell crank lever 67 which is' fulcrumed on the frame at 113, the other arm of said bell crank being connected by an adjustable connecting rod 68 with one of the counterweighted levers 60, so that a turning of the said cam gear 27 causes the levers 60 to swing and raise and lower the gear box with its revolving brush spindles. The adjustable connection between the connecting rod 68 and the bell crank lever 67 comprises a sleeve 69 pivotally connected to the upper end of said connecting rod and slidably mounted on the arm of the bell crank 67 and controlled by a right and left hand screw 7 O which is threaded in lugs on the sleeve and the bell crank lever respectively.

The connection between the connecting rod 68 and lever 60 is a yielding connection that will release the connecting rod 68 upon the occurrence of an abnormal resistance to the upward movement of the brush spindles. This connection preferably consists of a pair of rollers 71 which are mounted on the lever 60 and are held by adjustable spring pressure in engagement with notches on opposite sides of the connecting rod 68, said rollers being capable of yielding by moving apart when their spring pressure is overcome and permitting the rod 68 to slide therebetween. A rod 72 is connected with one of the rollers 71 and connects with a bell crank 73 in the line of the pivotal axis of lever 60, which bell crank is connected by a rod 74 with an automatic trip mechanism to stop the operation of the machine as soon as the connecting rod 68 is allowed to slip between the rollers 71, the movement of the rollers in spreading apart serving to vpull upon the rod 72 and thereby push upon the rod 74 to effect such result.

The automatic stop mechanism for stopping the operation of the machine when the connecting rod 68 is released vfrom its driving connection with the lever 60 or when one of-the bottle gage frames is lifted, as previously explained, comprises a spring actuated arm 75 which is pivotally mounted on a plate 76 secured to the frame and bears against a shoulder or fixed collar 77 on a clutch operating rod 78 which connects with a clutch operating lever 7 8 and extends to a position convenient to the attendant. A trigger plate 79 is pivotally mounted between ears on the plate 76 and at its upper part is provided with a raised inclined stop 80 to engage and hold the arm 75 in the full line position of Fig. 5 to which it may be moved against the action of its spring either by pressure on the rod 78 or by means of the handle 81 projecting from the upper end thereof. The movement of the arm 75 is limited by stop lugs 82 on the plate 76. The stop 80 on the trigger plate 79 is only in position to engage and hold the arm 75 when said trigger-plate is in its normal forward position to which it is pressed by a coil spring 83 in the rear thereof. The trigger plate 79, however, may

swing rearwardly to. disengage the stop 80 from the arm 75, as by such upward push on the rod 74, as before mentioned, for said rod connects with the forwardly extending arm 84 of said trigger plate 79. The fit of rod 74 in the forwardly extending arm 84 of the trigger plate 79 may be sufficiently loose to avoid interference with the swinging of saidtrigger plate. When so released by the stop on the trigger plate, the arm is swung by itsspring to its dotted lineposition in Fig. 5, and, in so doing pushes with its rounded bearin' surface against the shoulder of collar 7 on clutch operating rod 78, and thus moves such clutch operating rod to disengage the clutch and stop the operation of the machine.

The swinging movement of the trigger plate 79 to carry the stop out of the. path of arm 75 will also be produced by the movement of the arm 48 of the upper bottle clamp safety stop mechanism previously described as taking place when one of the bottles is lifted by the brush spindle. For this purpose the upper edge of the trigger plate 79 has a horizontal arm 85 projecti'ng from it in position to be engaged by the vertical trip arm 48 so that when the latter is swung inwardly it swings trigger plate 79 rearwardly against the pressure of its spring 83 to release the lever 75, whereupon the spring of said lever causes it to swing to the dotted line position .to open the clutch and stop the machine. In order that injury may not be caused to the machine by a careless'operator starting it in operation again after it has been automatical'ly stopped, and before the cause for stopping the machine has been discovered and removed, a 'dog 86 is provided tdengage the arm 75 and prevent its being returned to its normal position as long as the trigger plate 79 remains in its depressed position. Thls dog 86 is pivotally mounted on the trigger plate 79 and has a tooth 87 extending only part way across its lower surface 'so as to only be in the path of travel of a tooth 88 on the end of arm 75 when the trigger plate7 9 is in its depressed position. When the trigger plate 79 is in its normal forward position the arm 75 is free to swing without interference by the dog, the dog merely resting thereon so that after the obstruction hasbeen removed, and thereafter the trigger plate 79 has been restored to its normal forward position, thggnachine may be started in its operation by swinging the arm 75 to its full line position where it will again be engaged by the stop 80. This resetting of the arm 75 may be performed by pressure on the rod 78 or by pushing on the handle 81.

The automatic stop of this invention may be associated with thestop mechanism covered by Letters Patent issued to me on April 10, 1917, No. 1,221,889, the rod 24 thereof corresponding with rod 78 and the rod 18 thereof corresponding with rod 111.

What I claim as new and desire to secure,

b Letters Patent is:

1. A stop mechanism for bottle washing machines and the like, comprising a clutch actuating shouldered rod, a spring pressed.

stop out of its engagement with the arm,

and a dog pivotally mounted on the stop to engage the arm when released by the stop and disengaged fromthe arm when the stop is returned to its normal position. 3

2. An automatic stop for bottle washing machines and the like, comprising a clutch controlling rod, a shoulder thereon, a spring pressed pivotally mounted arm engaging the shoulder of the rod, a pivotally mounted trigger plate held by spring pressure in a normal position, a stop on the trigger plate engaging the arm whenthe trigger plate is in its normal position, means for moving the trigger plate out'of its normal position to release the arm, and a dog on the trigger plate to engage and hold the arm in its released position while the trigger plate is in its abnormal position but permitting the return of the arm to its position in engagement with the stop when the trigger plate is in its normal position.

3. A stop mechanism for bottle washing machines and the like comprising a clutch actuating rod, means for shifting the rod, a stop normally restraining said means, and mechanism for moving the stop out of its restraining position to permit the \shifting of the rod, said stop serving to engage the means when so moved to retain the rod in its shifted position until the stop is returned to its restraining position.

4. An automatic stop mechanism comprising a plate, a spring-pressed trigger plate pivotally mounted thereon, a spring-pressed shifting arm also pivotally mounted on the plate,- a clutch rod passing through an opening in the shifting arm and having a. shoulder engaged by the shifting arm, a stop on the trigger plate for engaging the arm and holding it against the pressure of its spring, means 'for moving the trigger plate to remove the stop from engagement with the arm, and a dog on the trigger plate having a tooth for engaging the arm and holding it in the position to which it moves when released by the stop.

In testimon whereof, I afiix my signature,

in presence 0 two witnesses.
