2 Claims. (Cl. 273-46)

This invention relates to pin spotting means for
use in` the usual bowling alley, and in other like
games, for >prop‘erly‘positioning pins, where pins
or the like are used, and aims to provide a novel,
simple and improved means for the above pur

Referring first to Fig. 2, the conventional bowling alley I, at its pin-carrying end or foot, is con
structed oi somewhat less thickness than the rest
of the alley, and I provide it beneath the surface
with a plurality of properly positioned, longitudi
nally extended channels or pockets 2 to receive
the pin-spotting elements, and these pockets, Fig.
1, are subsequently covered with a sheet of suit

the lower end enters an aperture 2 Ia., in the lower
end of the stud. The spring, of course, acts auto
matically if strong enough, otherwise it helps, to
return the stud 5 and bar I9 to normal position
35
when the latter is relieved of pressure.
The inner end of each bar I9, Fig. 6, is pivotally
supported by a link 22, connected thereto and
to a bracket 23 mounted on the cross support I2
on the alley I, to cause the bar to rise substan
tially horizontally with a short longitudinal mo

properly, Fig. 2, upon all the studs 5 in the same

game, where pins or the like are used in a similar
manner. It costs little to build it into a new
alley, and it may be readily installed in an old
alley, without destroying the alley end, and with
out substantially disturbing the floor of the build
ing.
Heretofore, it has been, the practice to use a
frame of triangular, rectangular or other shape,
to carry and raise the pin-setting studs, or the
10 like. This requires a clumsy, heavy and expen
sive structure, and extensive cutting of floor
beams, particularly if of metal or concrete, for
installation. I have very much simpliñed the
problem by the use of my several long stud-rais
