WASHER-COUNTER.

Application filed August 9, 1915.

To all whom it may concern.

Be it known that I, JOSEPH E. VINCENT, a citizen of the United States, and a resident of the city of Cambridge, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Washer-Counters, of which the following is a full, clear, and exact specification.

The object of this invention is the construction of an improved machine for auto.- matically counting and stacking washers, especially the rubber ones used in sealing glass jars. In producing the same I prefer to provide several arms rotatably mounted on a common turret, upon which the washers are strung by hand and by which the washers are presented to a toothed wheel which performs. the selecting, removing, counting and stacking.

Referring to the drawings forming part I of this specification,Figure 1 is a side elevation of a machine embodying my invention, parts thereof being in section. Fig. 2 is a face view of one of the washers to be counted. Fig. 3 is a detail sectional view of the detent carried by each arm for retain ing thereon the washers until they are presented to the wheel.

Therefe'rence numeral 1 designates the turret mounted to turn on an inclined spindle or bolt 2, and carrying several arms or rods 3 projecting radially therefrom. Close to the point which the outer end of each rod will touch in the lowermost position reached during its revolution about the spindle 2, is vrotatablyt supported a, wheel 4:.

formed with a predetermined number of teeth 5,as twelve,in a portion of its periphery. When each rod reaches this position of maximum inclination, the washers 6 thereon slide along down until stopped by meeting the smooth portion of the wheels periphery.

As the wheel slowly revolves, its first tooth engages and carries downward the outermost washer, whose place is immediately taken by'the second washer. This in turn is engaged and carried down b the second tooth, and so on until the twelfth tooth has disposed of the twelfth washer.

As each washer descends, it impales about the bifurcated standard 7 whose inclined leg 7 causes the washer-to take a horizontal position as it descends upon the table 9.

Specification of Letters Patent.

Patented Feb. 27, 191 '7.

Serial No. 44,465.

When the entire twelve have descended upon the table, and while thesmooth portion of the wheel is moving past and keeping back' the desired function of retaining the washers upon the arm 3.

When the turret is being turned and just before each arm 3 reaches its delivery position 1n front of the wheel, a suitable cam projection 15 is met by the inner end of the slender rod 13-. and presses upon the latter sufliciently to lower the detent to the position indicated in Fig. 1. This frees the washers from its detaining action and permits them to slide on into engagement with the wheel 4.

I prefer to form each leg of the receiving and reversing member 7 with a too 7 proj ecting outwardly at its lower end, and upon which the washers accumulate, as shown in Fig. 1. 'When the desired number has been received thereon, as the usual dozen,

the legs 7, 7 are pressed toward eachv other,

thereby freeing the washers from the support of the toes 7 and permitting the pile to drop to the table 9. Said legs being of resilient material, they immediately (return to their normal condition when released, and become ready to receive the next accumulation,1while the pile beneath is swept into a box, or otherwise taken care of.

Although each arm 3 is designed to accommodate a large number of washers, the last thereof will finally reach the counting and removing device, and another arm with a fresh supply is to be swung into position. As this. is done, the member 7 is removed from the first arm and suspended from the.

second one. For suchpurpose, each arm is formed with a socket 16 with which the accumulated nular devices, means for withdrawing said devices from an end of said-arm, and an accumulating instrumentality suspended from said end of the arm, said instrumentality being composed of a plurality of members each having at its lower end a stop for temporarily supporting said annular devices until a proper number has accumulated thereon, said stops being adapted for disengagement from said devices, to permit the number to drop to a support beneath. v

2. A coiinter for washers, comprising an arm designed to receive and support a quantity of annular washers, means for withdrawing said washers from an end of the arm, and an accumulating device comprising a plurality of legs suspended at their upper ends from said end of the arm, and stops at the lower ends of said legs for temporarily supporting said washers, the upper ends of said legs being near together and their lower ends being separated to .distances nearly equal to the inner diameters of said washers.

3. The combination with an arm designed to support a quantity of. annular washers,

' slidable parallel suspended from the end of the arm and having resilient legs each wardly extended toe at its lower end, upon having an out-- which the washers accumulate as they leave the arm.

4. An arm pivoted at one end to swing in an inclined plane, a detent pivoted in one end thereof, said detent having an elbow, a slender rod engaging the elbow and with said arm, a helical spring acting on the slender rod to normally retain the detent elevated above the surface of the arm, and a fixed cam projection disposed to meet an end of said rod when the arm is in its lowermost position and to depress the detent, in combination with a toothed wheel positioned at said lowermost point.

In testimony thatl claim the foregoing invention, I have hereunto set my hand this lth day of August, 1915.
