THOMAS J. SLOAN, OF NEW YORKVN. Y.

Specification of Letters Patent No. 8,027, dated April 8, 1851.

To all whom t may concern:

Be it known that I, THOMAS J. SLoAN,

of the city, county, and State of'New York,

have invented certain new and useful Im- `provlenfienfts in l`Bowling-Alleys and Pins Therefor, and that the following is a full,

clear, and exact description thereof, referand trouble is lost in setting them up when y knocked down by the players. Many seriousinconveniences and sometimes accidents result from this stateof things whichiit is the object and purpose 'of this invention to overcome and avoid. I propose to accom-` plish this by an arrangement for setting all the pins up by a single `motion of a lever at what is called the head of the table, and by which also the pins are all brought at once into their proper relative positions.

The first part of my invention consists in` making the `bases of the pins spherical when thislis combined with the use of a set of elevating sockets (one for each pin and each onemovable on a fixed rod) and` v my pins b in the same relative positions with respect to each other as is now" practised. The bosses c, permanently attached to the frame CZ of the table, pass up through ten holes in the table to a level with it, the upper end of each being circular socket e in which ts the spherical base f, of the pins b which are sustained therein by the tension of a small spring 7L in the bottom of the said socket. The tension of this spring is just sufficient to Sustain the pin in a vertical position. When the pins are struck by a ball thrown by a player, the tensive force of the spring h is overcome, and they fall over but not enrovided with a Witnesses:

tirely to the table,as their ends are confined in the circular sockets e. When one pin is lmocked from the force of the blow into this position, it rotates around the center of its spherical base and causs" those pins within its reach to fall down. Y

In setting up the pins all together, `the I operatic-n is as follows: Under the table and directly below the pins is what I call the elevator c' which is a board provided with ten holes directly opposite the ten holes in the table a. This elevator is horizontal and has a vertical motion on the bosses@ and guided by the stud pins j. Between the table and the elevator, and surrounding the bosses c, are what I` call the elevating sock-` et-s or rings lo, which, when the pins are down and it is desired to 'setthem up, are caused bythe motion of the elevator i to bear against the shank or largest part of the pins and rise through the table in the posi` tion seen in dotted lines in Fig. 3, until the p pins are all brought into a vertical position in which they are sustained bythe tension of the small spring 71 in connection with the circular sockets e as` before described. The elevating board being then lowered the elevating sockets sink to a level with the surface of the tableand'the pins are ready to receive another ball.

Motion is communicated to the elevator by means of the forked levers Z and inflexible rods or connections m from the hand lever 0 at the head of the'table or by any othervarr'angement desired. The balls are returned by means of inclined ways or otherwise. i

The advantages of my improvements consists in the saving of time and labor in settingwup the pins, saving the expense of an attendant for performing this duty, and the absence of liability to accident to persons from the flying of the pins or balls.

What I claim as my invention and desire to secure by Letters Patent is- Elevating thepins of a bowling alley by means of a set of 'elevating sockets operated from the head of the table when this is combined with any well known device or devices which will permit the `pins to fall and sustain them in a vertical position after they are elevated, substantially as described.
