In the drawings Figure 1. is, a, top plan view of my device; Fig. 2. isa sectional sideelevation thereof in the plane indicated by line: 2.2 in Fig. 1., with the. pin-lowering apparatus in normal position, and-part of the pins in raised position; Fig. 3: is-a pars tial similar view withl-thei-pin-lowering apparatus. in the position occupied at-the end of. the down-stroke; Fig,- 4. is a=sectiona1 plan viewin the plane-indicatedby line 4+4 in Fig. 3; Fig. 5.-.is alike view in the plane indicated byline -5--5 in Fig- 3 Fig. 6. is a sectional siderelevation in theplane indicated by line 6-6in Eigc 1; Eig. 7 is apartly sectional'plan View ofthe ball re? turning-device; Fig. 8.- a partly. sectional side elevation of said device, and Fig. 9 is a front elevation of the: housing on top of'my device: with some-of.theaindicators, hereinafter described, projectingtherefrom.

Referring to the drawings,-the reariportion11 of a. bowlingalley. 12, of ordinary construction, is surmountediby a platform 13 vprovided with vertical openings 14, cor re spondingin numberto thevnumberof bowling pins 15 to-be-used, and locatedso as to have the center of their front edges located substantially above the center of the front edges of the correspondingbowling pins, respectively, when the latter are in position on alley 12. At a suitable distance i above platform 13 another: platform-.16 is located, and to the underside thereof are attached vertical guide brackets 17, each. preferably consisting ofiaflatmetal str1p= bentdouble so as to form a. vertical slot 18.

One; of these. brackets is located above thecenter of-the rear edgeof eachof openings 14. At a-z-suitable distance back of each of brackets 17 there is fastened to the underside of platform :16, aacarrying bracket 19, of like construction asgulde -bracketsll,

In each of brackets-19 there is looselymounted, on arivet 20, the lever 21,from the forward end of which is suspended, by. means of hanger 22, one of pins 15, while to-the rear end of each of said levers, 21 is attached a weight 23, heavy enough to lift not only corresponding pin 15, but also cor+ responding vertical stem 24, and the: arts attached thereto, one of said stems sing slidably mounted in platform 16,- above. the

frontend-ofi each of levers-21. Eachof said stems at its lower.end is provided with a horizontal disk.26,- adapted to beengaged housing 31, superimposed onplatform16,

in limiting the upward movement of frames 27 and stems 24, and thereby also of the forward ends of levers 21, and of'pins- 15. By contact with-the upper surfaceof plat form 16 lips 29 also limit the downward movementofframes 27 .and stems 24. Slots 32 inroofs 30 are penetrated by frames 27 permit. of vertical sliding motion thereof, and serve to keep the faces of frames 2.7 toward the players end of alley 12. Housings 31 are of a. height substantially equalto that of frames27, so that when lips 29 contact with platform 16, cards 28 are entirely within housings 31, thus being concealed from view; while whenlips 29 contact with roofs 30, cards 28 are in full view above housings 31.

At .a height about equal to that attained by disks 26 when lips 29 are in contact with roofs 30, there are mounted in suitable sup; ports 32, transverse rods 33, formed, in .front of each ofcarrying brackets 19 with a projection 34, adapted to depress, when ,moveddownward, the forward end of corresponding lever 21. The ends of rods 33 are bent downward, and then outward, so as to form cranks 35,-the ends 36 of which are connected with each other by rod 37, to the frontend'of which is attached extension spring 38, while its rear end is connected, by a suitable link 39 to the upper end of'a vertical lever40, the lower end of which is connected, by means of a wire 41, with the rear arm 42 of an angular lever 43,.the forward arm 44 of which carries at its outer end a pedal 45 located at the of platform 16 transverse metal plates 46] players .end of alley 12. On the underside tent notches 48 in the front ed es of hangers 22 whenever the front ends levers 21 are depressed suificientl -for pins to touch alley 12. There is a so attached to the underside of platform-1.6, a transverse frame 49, preferably mounted in eyescrews 50 in such a waig. as to be slidable forward and back- ,ward,"-"but normally held, by extension springs 51, in its forward position.\f1his frame is arranged so that it passes immediately in the rear of one of ins 15, and in front of a number of other pms 15.

Back of portion 11 ofalley 12 a transverse ball chute 52 is arranged, inclined toward, and terminating in, a depression 53 at the rear end of return runway 54, for balls 55.

Just back of depression 53 a ropelling device is arranged as follows horizontal bolt 56, mounted in brackets 57 and 58, is provided, at its rear end, with vertical crosspin 59; some distanceback of its middle with horizontal crosspin 60; at its front en with bufi'erplate 61; and, between bufferplate 61 and bracket 58, with compression spring 62. A spring 63, pressing down on bolt 56, secures the engagement of looking notch 64, on the underside of bolt 56, with bracket 57 whenever bolt 56 is pushed back, against the pressure of spring 62,

sufficiently far to make bufferplate 61 lie substantially flat against the rear wall 65 of runway 54. A suitably mounted trans-' verse rod 66, .provided at one end with depending arm 67, terminating in fork 68 which straddles bolt 56 in front of crosspin 60, carries at its other end upright arm A 69 (see Fig. 3) which'is flexibly connected,

by link .70, with the lower portion of lever 40 in such a way'that whenever this lower end of lever 40 is pulled forward, bymeans of wire-41 and lever'43, bolt 56 is pushed. back by means of fork 68, acting on crosspin 60. A bellcrank 71 is arranged, and

connected, by wire 72, with the lower end 73 of another lever 74, located at the players end of alley 12, in such a way, that whenever the upper end 75 of lever 74 is pushedback a short distance, by means of pushbutton 76, notch 64 is lifted out of engagement with bracket 57. A lever 77,

mounted in a suitable frame 78, is arranged, and connected by wire 79, with lever located at the players end of alley 12, in such a way that by a pull on the handle of lever 80 bolt 56 may be pushed back, against the pressure of spring 62, by the lower end of lever 77 bearing against crosspin 59, Extension spring 81 is provided to then. be thrown normally hold lever 7 a position wherein its lowerend bears against bracket- 57. A

hump82 is providedin runway 54, near the players end of alley 12, to prevent a rolling back of balls 55 toward the rear end of-runway 54. To end 75 there is connected, in addition to pushbutton 7 6, the lower end of a lever 89 the upper end 83 of which 6 forms the movable ed e of what may betermed an elastic coin-chute 84 through which a coin 85 may be forced from above,

by means of pro'ection 86 on lever 87, in

such a way that 1n its assage it will force end 83 sufficiently far orward, to cause the lower end of lever 89' to move lever 74 in such a way .as to "release notch 64 from bracket 57. 4

The operation of my device is as follows --Pedal 45 is pushed down. Asa result thereof the lower end of lever 40 is pulled forward, and thereby, through link Y 70 and rod 66, bolt 56 is pushed back until notch 64 engages bracket 57. At the same time, the upper end of lever 40 being pulled backward, od 37, being connected to lever.

40 by link 39, .pulls cranks 35 backward,

and causesjprojections 34 to bear down on the forward ends of levers 21,.until detent notches 48 engage edges 47. As .a result of this movement pins 15 are placed in proper position on alley 12, and stems 24 with frames 27 are caused to drop down until cards 28 are concealed within housings .31. At the end of this movement, pedal 45 being released, spring 3.8'at once pulls rod 37, and through it cranks 35, projections 34, lever 40, lever 43, arms 69. and 67, and fork 68, back into normal position; A ball may b one of the-players in the ordinary way. 1 f it hit a pin 15, the corresponding notch 48 is disengaged from the corresponding edge 47, thus permitting cork I responding weight 23 to lift such pin 15 beyond the reach of further balls 55, and

incidentally to push corresponding stem 24 and attached frame 27 upward until card 28, held by such frame, is fully displayedabove its housing31. Ball 55, having spent its energy, rolls downchute 52 untilit rests T in depression 53. A push on button 76,

or the forcing of asuitablecoin through chute 84, will then lift notch 64 out ofengagement with bracket 57, thus releasing bolt 56, and causing spring'62 tohurlits forward end with buiferplate 61' against ball 55 in depression 53, thereby-propelling said ball along runway 54 and over hump 82 until it rests atfthe players end of runway54. By a pullon the handle of lever 80 bolt 56 is thereupon pushed back, through lever '77, against the pressure of spring 62, until notch 64 again engages bracket 57, whereupon spring 81 pulls levers 77 and 80 back into normal position. Other balls may then be thrown, releasing all pins 15 directly hitby them, and if they hit the pin in front of frame 49, also releasing all of the pins in front of which frame 49 passes. Each ball thrown may be immediately returned by a push on button 76,

or the forcing of another coin through chute 84:, and the propelling device be made ready for another ball 55 by a pull on the handle of lever 80.

At any stage of the playing all of pins 15 may be replaced in position on the rear end of alley 12 by pushing down pedal 45. Whenever this is done the ball-propelling device at the rear end of runway 54 is automatically put in propelling position, and all of frames 27 with cards 28 are automatically dropped back into housings 31, as above described. Cards 28 may be used to indicate either the name or the member of the different pins, or the playing value of each pin struck, or both.

Manifestly lever 89, chute 84 and lever 87 may be omitted; this will be done where the outfit is used for private purposes, or rented by the hour etc. On the other hand pushbutton 76 may be omitted. This will be done where it is desired toexact payment for every throw; the idea being to use only one ball for playing, and thus to compel the party who wants to use it, to part with the necessary coinbefore the ball becomes available at the players end of the alley. The coins in this case will drop into a locked receptacle 88 under chute 84.
