Application led August 16, 1913. Serial No. 785,180.

To all 'Hf/wm 'zit muy concern.:

lie it known that we, Anneau' YV. hun, ot Blount; Rainier, in the county ot Prince. George and State of 'Marylanxh and Josemi A; Kimymonn, otllhishington, in the Districtot Columbia, citizens of the lluit-ed States. have invented certain new and usetal Improvements in Aunnunitimnlloists; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to loading ordnance, and more especially to the hoisting devices for raising heavy ammunition, as from the hold or magazine near the bottoni ot a gunhoat, through the various declis to the interior o't the turret.

The object et the invention is to produce an extremely simple mechanism for hoisting heavy shells, and one in which the shell is taken up automatically when it is fed to the hoist and is delivered automatically when it reaches the upper end ot the shaft, whereby hitman services are dispensed with further than the act ol' feeding the shells to the lower end of the hoist and taking them from its upper end and placing them in the cannon. This object. is carried out by constructing the hoist in the manner hereinafter more fully described and claimed and as shown in the drawings wlnwrein- Figure l is a vertical section and Fig. 2 a. front elevation ot this hoisting mechanism complete; Fig. 3 an enlarged section on about the line l-3 of Fig. 2, partly broken away, and Fig. 4. is a section on the line l--l of Fig. 3; lfig. 5 is an enlarged section taken about on the line 5-5 ot Fig. l: and Figs. C and 'T are sections on the `lines ti--t'i and THT respectively ot Fig. 5. Figs. S and f) are diagrams in elevation showing the di'lferent positions ol an ascending shell under the impulses of the two cams.

l'Ve have diagrammatically illustrated in Fig. l the internal construction ot' a battleship, or so much thereof as is necessary to a clear understanding ot' this invention. In the lower portion ot said ship, as perhaps within the hold ll'. is disposedA the driving mechanism for this ammunition hoist, so that, it the motor he an electric motor li as shown in Fig. 2, the electricity will he below the loading tloor L which ferais the bottom of the magazine M as shown and there will be no danger that a. spark will reach any combustible oluexplosive.. Ylrom said loading floor L the shaft S of this hoist extends upward, preferably at an angle of about 150, through the. deck or several decks l) and into the turret T. where the delivery end of the shaft S will be near the cannon or gun which is to receive the .unmunition. lt is to he understood that the general practice is to retain the ammunition in the magazine as long as possible, but during gun practice or while the boat is in action the shells are fed up the hoist as rapidly as they are used by the gunner-s within the turret or elsewhere. At other times, however, the ammunition is stored below, the hoist is out otl action, the guns are empty, and everything is as safe and ship-shape :.s possible.

In the drawings, the motor E is shown as geared at G to a main shaft l mounted in suitable hearings 2 carried on a support 3 and perhaps having a heavy ily wheel l, and on this sh att are secured two cams which are exact duplicates oit' each other although disposed in direct opposition, and a description of one will sullicc for beth. As best seen in Fig. 3 the cani 5 is exactly round but mounted otl'-ce.nter on the shat't l, its face is channeled or grooved as at G ior the reception of a tongue 7 at the lower end of a shoe S whose lower l'aee is curved and rests on the upper side of the cani as shown, and in order to reduce. friction this lower -lace. inap7 be oiled through the oil cup tl. To prevent the possibility thaty the shoe will he thrown ott the tace, we preferably provide the shoe with a hook itl which passes down over the outer side ot' the cam 5 and has its bill loosely disposed within an annular groove 11 formed in the cani as shown. Ordinarily the weight ol the Shoe and the rack bar carried thereby (as will bey explained below) willv hold the lower face et the shoe tightly in Contact with the upper or active face of the cam, hutit1 for any reason there should be a tendency to dislodge the shoe therefrom the hook 10 engaging the groove 11 will prevent. It desired, an antifriction roller l0 11u137 be carried by the hook lll. As seen in Fig. l the companion cam and shoe are con structed in precisely the same manner, with the di lierence of course that the hook is on the opposite Lace so that theif'iiodies of the two cams may run side by side and as close to each other as possible. n

From each slice rises a rack bar 12, its

lower end being by preferencepivotally and perhaps removably connected with the shoe as at 13, and its body passing through a suitable guide 14 carried by the licor L, and extending thence V`upfward throughoutthe length of the shaft Said shaft, asbest seen in Fig. 5, will by preference be made in the shape of a sheet-iron tube 15, cut away at its lower end the frontl side to produce an inlet 16 forA the shell or other. piece of ammunition A, and provided at its rear side with an oiset best indicated in Fig. 5, and which 'forms the housing for the two rack bars 12 and 12. That -is to say, a sheet metal strip' 17 is bent into substantially lilshaped cross section, and the arms of the U connected with the back ot the tube by brackets or angle plates 1S, the

A rear side or the tube 15 being provided lloosely receive pins 21.I

with slots'orcut away entirely to permit -the projection into it of the teeth ot' the rack bar-s yet to be described. These bars stand against oppositel faces of an uprigl'it strip -29, andfthey preferably have longitudinal ins 19 which project back into the tl-sliaped housingifi" as-seen 'in Fig. and are slotted at intervals as seen at 20 in Fig. 1 so as to The latter extend across said housing and through the strip 29, and prevent the dislodgnient of the bars. Atthe upper end of the shaft S brackets 22 carrying rollers 23 on either side of the mouth or outlet end ol2 the same, and over these rollers the shells il. may be passedas they are delivered troni the hoist, as indicated in dotted lines in Fig. 2. clear that' the and proportion et' part-s is immaterial, and it is obviously necessary that the elevator shaft S' extendthrough' all the intermediate decks D although we have illustrated but one in Fig. 1,

rllhe teeth ot the rack bars and their exact disposition are matters of importance in this invention. Each tooth is in the form of a dog whose upper or active 'face 31 is fiat but whose inner end is beveled beneath said face as seen at 32 in Figo, and the entire dog is mounted in a recess 33 in the body of the bar 12., which recess is disposed transverse to the length of said bar and is there fore almost horizontal when the bar is inclined about 15. l? rom the back ot the dog a rod or bolt 34 projects rearward, through an expansive spring 35 which is disposed between the rear end of the dogv and the rear end of the recess, and then through the rear wall of the bar 12-Where it receives a nut 36. By\ removing the latter the dog may of course be taken out of the recess 33. By ad- .justingthe hat 36 the extent to which the active face or corner of the dog will project lt will be' beyond the ifront face et the bar 12 may be regulated. These dogs constitute the. teethv throw ot the cauifromgits lowest position toits highest position will be six inches, and

while i that will be the length of the path through'v which theY rack bar reciproeutes. On this understanding and with cams having a throw ol.e six inches,` the active Aaces ofthe teeth .will be disposed slightly less than twelve inches apart, and in vsuch position on the two bars that they will besubstantially in .register with Aeach other whenone bar is up and the other bar is down, as seen in Fig. 2. lilowever, the tact that theyvare not exactly in register is important as will be seen. ll'e have shown the teeth on the right hand har 12 as set a little lower than those on the ,i

lett hand bar 12 and we have also shown the right hand bar as having one additional tooth at its lower end. which tooth lis pur! posely disposed a little below the level of the loading ioor L when this bar is down.

Referring now to the diagraniinatiu viewsy illustrated in Figs. 8 and 9, when the shell A is ted into this improved ammunition4 heist, its lower end sliding on the floor L passes over the active tace ot' the lowerniost tooth a which at this time stands a trifle. below said floor as just described. A

one-halt' revolution of the shaft 1 then causes the cam 5 to raise the bar 12 six inches and the cam 5 to permit the bar 12 to descend six. inches so that all teeth on the` 'right hand bar now stand relativelyr twelve inches higher with respect to the teeth on the left bar than they did before the shaft made this half-revolution. lslowever,l the fact that the teeth on any bar are a trifle less than twelve inches apart causes those on the left hand bar at this time to stand a trifle below those substantially opposite to .them on the right hand bar, and as all teeth or dogs which are not pressed to the rear by the weight ot the shell will be pressed tori'io ward by their springs 35, that .dog (iy iinmediately beneath the lower end ot the shell on the left hand bar 12 will at this time be.

projected forward into position to support said shell. shaft for another half turn restores the parts to the position shown in Figs. 2 and 8, but this time the shell A' is carried up by Continued revolution et the.

the. lett hand rack bar to such a point in the shaft S that the next dog' 7) on the right hand rack bar may engage beneath the lower end ot the shell to raise the latter further on the next succeeding` milt-revolution of the shaft. Thus it will be seen that the teeth or dogs on the two alternately reciprocating rack bars raise the shell A step by step throughout the length of the shaft S until it reaches the upper end thereof and can be removed over the rollers 23. this piece of ammunition has passed upward out of the inlet 1G sulliciently far, the men at work within the magazine may present another shell to the hoist and it follows the first one up the shaft; in fai-.nit is quite probable that if the shells or pieces ot' ammunition are. being rapidly used on the gun deck or decks, they will be moving` up the shaft constantly. So rapid will be the supplythat it is quite possible the shaft S may be provided with openings as indicated at O in Fig. 'l so that it' there be guns mounted on the deck indi 'ated at l) the ammunition therefor could be supplied through the same hoist by taking it manually out of such opening. In fact, while we have described this device as particularly useful as an ammunition hoist, it will be clear that the same could be employed for elevating other articles than pieces of ammunition, and we reserve the right to put our invention to all uses to which it may possibly be adapted.
