Rising from the passage 46, adjacent the opening 56 is a fixed support I54 to which there is re:-

mova'oly secured a fixed contact member I56 that normally contacts a movable contact member I58. The movable contact member I68 is pivoted between the spaced legs of a .U-shaped bracket I68 mounted in the passage 40 andsupports a downwardly and forwardly inclined. arm or operating plate I62 that is disposed in. the opening 56.

The contact members I56 and IE8 are.v connected to circuit wires I64 that extend to a motor operated conveyor I66 having a plurality of rockable pin supporting cradles I68which are rocked by a cam I69 on a contact member III atthe rear of the chute E6 whereby the pins Il0 in the cradles I68 will roll down the member I'i'I to engage a. stop or turner plate I12 mounted on the chute.

Arcuate guides 1'14 depend from the chute I6 and from each of the openings in the passages, it being noted that the length of the guides I'I4 increase from the passage 34 to the passage 40.

and decrease from the rear of the chute to the forward endv of the chute since the chuteis to be inclined downwardly from the passage 40 to the passage 34 and downwardly from the rear of the chute to the forward end of the chute.

In practical use of the present invention, the conveyor I66 rotates and pins are discharged from the conveyor and roll down the member I'II where the same partially contact the plate I72 to turn the pins slightly.

The pins slide base first down the chute III and the first pin enters the passage 34, slides over the closures 66, 66 and T0 and falls into the opening 62 where the same urges the arm I2 downwardly and rearwardly to raise the closure 66.

The second pin sliding down the chute will enter the passage 34, slide over the closures 68 and I0 and contact the closure 66 so that the same will be directed into the opening 60 to force the arm H of the closure 68 downwardly and rearwardly thereby raising the closure 68.

The third pin, entering the passage 34, will ride over.the closure I6, contact the plate 68, and will then be directed into the opening 62 to move the arm I2 of the closure I0 downwardly and rearwardly to raise the closure I0.

The fourth pin, entering the passage 34, will contact the closure 70 and be directed into the opening 64 to move the arm I08 downwardly andrearwardlyto raise theclosure create 92.

The fifth pin entering the chute It) will engage the gate 92, be directed into the passage 36, slide over the closures l8 and 80, and will enter the opening 54 to move the arm 82 of the closure 18 downwardly and rearwardly and raise the closure 18.

The sixth pin entering the chute Ill will enter the passage 36, engage the closure 18, and be directed into the opening 14 thereby moving the arm 82 for the closure 8t downwardly and rearwardly to raise the closure 80.

The seventh pin entering the chute it) will enter the passage 36, contact the closure 8|], and be directed into the opening it to move the arm I24 downwardly and rearwardly to raise the gate 94.

The eighth pin entering the chute l0 will engage the gate M and will be directed into the passage 38, slide over the closure 86, and will enter the opening 55 to move the arm 88 downwardly and rearwardly to raise the closure 86.

The ninth pin entering the chute IE] will be directed into the passage 38 to contact the closure 86 whereupon the same will enter the opening 84 to move the arm !38 downwardly and rearwardly to raise the gate 96.

The tenth pin entering the chute will engage the gate 96 and be directed into the passage 40 where the same will enter the opening 58 to move the arm I62 downwardly and rearwardly to space the contact members I56 and i513 and break the circuit to the conveyor.

Obviously, the instant structure is capable of being used in conjunction with a sweeping mechanism whereby the pins may be swept to a conveyor that leads to the conveyor ltfi, so that after the pins have been struck by a ball the said pins may be again set up.

It should be noted that the instant chute assembly is to be used in conjunction with a pin cage assembly (not shown) located under the chute, and when the pin cage assembly is lowered or moved below and from the chute assembly to deposit pins on the alley, the gates and panels on the chute assembly return to their normal position.
