Application May 1, 1937, Serial No. 140,204 2 Claims. (Cl. 273-46) In the pocket cover member 3 are secured, Figs. E," 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 5. pose, having, among others, the advantages and l, 6, 9, at proper points, as the pin seats, the nec essary number of sockets or stud bearings 4a, for the proper number and arrangement oi the pin spotting studs 5, and the bearing may be con- novel features hereinafter described and illus trated. „ veniently secured in position by threading one ` end and screwing it into a plate S, secured as by screws or pins 1 to the under face of the cover In the drawings of one embodiment of my in vention selected for illustration and description 10 herein: member 3. The alley end, Figs. 3, 6, is` provided with usual _ suitable cross supports 8, 9, I0, II, I2, and the members 9, III, Figs. 3, 6, are cutaway to provide Fig. 1 is a plan of the pin carrying end or foot of the conventional alley, as it appears with my clearance for the outer ends of levers I3, pivoted in brackets I4, Figs. 3, 5, 6, the inner ends I5 novel pin-setting mechanism installed; of the brackets being turned downwardly and ` Fig. 2 is a plan of the alley end broken away, as outwardly, and secured to the member Ill. 15 the mechanism appears installed therein, with The outer ends of the levers I3, Fig. '7, are pro the mechanism covering element of the alley re vided with links or other suitable elements I6, for attachment to a foot treadle I1. moved; Fig. 3, a Vertical, longitudinal section on the The inner ends of the levers I3 are connected line 3-3 of Fig. 1, looking to the left, and partly as by pins I8 with stud-raising elements such as broken away, showing one of the levers in its channel bars, or links, I9 of suitable length to operate the appropriate number, either one or pocket; Fig. 4, an end view of the structure of Fig. 2, more, Aof pin receiving studs 5. In Figs. 5, 6, showing the foot treadle for raising the pin-spot broken out for convenience, the bar I9 is shown with a shallow shoe 2D, which carries the lower ting levers; Fig. 5, a partial plan of a section of an alley end of the stud 5 slidable vertically in the bear with its top removed, on an enlarged scale, show ing 4, within the pin seat on the playing surface, ing a stud-raising lever, as the one on the left of and the stud carrying a helical spring 2 I , the up« Fig. 2, in its pocket in the alley, and which lever raises only a single stud; Fig. 6, a side elevation of the center stud rais ing lever, Fig. 2, partly broken away at the cen ter for convenience, and showing the alley struc per end of which seats against the plate E, while ture in section; Fig. '7, a vertical section on the line 1-,-"I, Fig. 6, showing the pivot joint of the stud raising le ver; Fig. 8, a vertical cross section on the line 8-»8 oi Fig. 6, looking to the right; and Fig. 9, a vertical section of a portion of the structure shown in Fig. 6, but showing the base of a pin broken away, as it is spoted by the stud. 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 tion, when actuated by the lever I3, so as to act properly, Fig. 2, upon all the studs 5 in the same Vertical plane, when the bar acts on more than one stud. By placing one foot upon the treadle I'I to depress it and raise the bar I9 and studs 5, the pins 24, which have stud receiving sockets 25 in the lower ends, may be quickly and accurately spotted and set up, without danger of any of. them being out of position or falling down, with con 50 sequent loss of time and extra work. I believe my pin-spotting mechanism to be the able material, as wood or ñbre~board, or the like, simplest and most convenient and practicable, 3, known as a pin plate, secured by any suitable means, as screws 4. This pocket covering sheet 3 is, of course, of a thickness to complete prop erly the level playing surface of the alley. as well as least expensive, device of its kind that Iknow of, for use with the usual alley; and modl iied within the spirit of my invention for any 55 2 2,1 17,204 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 same may be made, all within the spirit and scope of the appended claims. I claim: 1. Pin spotting means for bowling alleys having stud openings therein, said means comprising a plurality of stud raising bars longitudinally ex tended beneath the alley in parallel arrangement. studs loosely positioned on the bars and adapted, when projected through the stud openings in the alley, to spot the pins, the bars operative indi 10 vidually on the studs for the pins normally grouped in the same vertical planes with the re spective bars, a lever and a link respectively se Where formerly it was necessary to cured to opposite bar ends with supports for said remove, usually, the obstructive cross beams lll,r levers and links, and a foot treadle with means 15 or their equivalents, or other supports of the alley connected thereto and separately to each bar whereby each bar is separately adjustable and re floor, in order to introduce the frames for rais movable While preserving the assembly as a ing the pins, I can now avoid this work and ex Whole. 20 pense to a great degree by the use of individual 2. Pin spotting means for bowling alleys and 20 )ars I9, or the like, which are accommodated by the like with stud receiving passages therein, said the few channels in the floor structure inexpen means comprising a plurality of stud raising, sively made. Furthermore, my construction provides another parallelly extended bars beneath the alley, and 25 important advantage, namely:-if. any trouble is studs loosely resting on the bars and adapted to had with any particular pin stud, it may readily be projected through the said passages in the alley 25 be attended to Without disengaging or añ'ecting iloor to engage and spot the pins, said bars oper the remainder of the mechanism. In the usual ative individually only on the studs grouped in instance, trouble with one stud affects the Whole the same vertical planes with the respective bars, so stud-raising structure. My structure, with its levers and links for the opposite bar ends and relatively few elements, is much more simple to supports for said> links and bars, the bars con 30 operate and easier than any of the conventional nected operatively only at their rear ends, and a 15 ing bars I9. ones that I know of. My invention is not restricted to the particular 35 embodiment thereof illustrated and described -treadle with means for connecting it to and for operating the bars, each bar being free of any lateral frictional drag from the other bars. herein, as obviously many modiñcations of the 35 JOHN F.
