CLEMENT C. OLAVVSON, OF NEWVARK, NEW JERSEY.

COIN-CONTROLLED AIR-PUMP-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 619,279, dated February 14, 1899. Application filedJune 30, 1898. Serial No. 684,779. (No model.)

To all whom it may concern.-

Be it known that I, CLEMENT O. CLAWsoN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Coin-Controlled Air- Pump-Operating Mechanism; and I do hereby 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The present invention has reference to a novel construction of coin-controlled mechanism in which by the depositing of a coin a pump-operating mechanism becomes freed and can be worked by the turning of a crank.

The object of my invention, therefore, is to provide a novel construction of apparatus of this character in which after the mechanism has been freed by a deposited coin one or more air-forcing pumps can be operated to drive or force the air through a pipe or tube connected with the casing of the apparatus and from which the air can be forced to inflate the object connected with or attached to the end of the said tube.

One of the principal objects of my present invention is to provide a machine or apparatus which can besecured to the side of a building or post to enable riders of bicycles to inflate the tires of their vehicles along the road by simply dropping a coin into the slot of the apparatus, attaching the air-inflating tube connected with the apparatus to the tire of the wheel of the bicycle, and by turning the crank of the apparatus forcing air into the tire to fully inflate the same.

A further object of my invention is to provide an apparatus or machine of the nature and for the purposes stated which shall be of a compact, reliable, and efficient construction.

The invention therefore consists in the novel construction of coin-controlled mechanism and means for driving or operating an air pump or pumps; and the invention, furthermore, consists in the novel features of construction and the several arrangements and combinations of the parts of such mechanism, all of which will be fully described in the accompanying specification and. finally embodied in the clauses of the claim thereto appended.

The invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a front view of my novel construction of apparatus, and Fig. 2 is a top view of the same. Fig. 3 is a front View of the apparatus with a pair of doors in the front of the casing removed to illustrate one arrangement of the controlled mechanism within the casing, the several parts being represented in their normally inoperative positions; and Fig. 4 is a horizontal section of the casing, taken on line 4. 4 in said Fig. 3, said view illustrating in top view the general arrangement of the operating mechanism embodyin g the principles of this invention. Fig. 5 is a longitudinal vertical section of the easin g with the pump-operatin g mechanism represented in front elevation,the coin-controlled mechanism being represented in its freed position to permit the actuation of the pumpoperating mechanism. Fig. 6 is a horizontal section of the several parts, said section being taken on line 6 6 in said Fig. 3. Fig. 7 is a longitudinal vertical section of the casing and a front elevation of one arrangement of three air-pumps, a three-way valve and connecting-tubing, and a means for operating said pumps; and Fig. 8 is ahorizontal section taken on line 8 8 in said Fig. 3. Fig. 9 is a vertical cross-section taken on line 9 9 in Fig. 5, illustrating a portion of the coin-chute in crosssection and the operating mechanism directly connected therewith being presented in end elevation, but the arrangement of air-pumps being omitted in this view. Figs. 10 and 11 are a face and edge view, respectively, of a cam and a portion of the operating-shaft on which it is arranged for working the air pump or pumps. Fig. 12 is a longitudinal vertical section of one of the air-pumps. Fig. 13 is a horizontal section of the same, taken on line 13 13 in said Fig. 12; and Fig.14 is a similar section taken on line 14 14in said Fig. 12 when looking in the direction of the arrow a in said figure. Fig. 15 is a side view of a guide-frame and rollers employed in connection with the air-pump. Fig. 16 is a longitudinal vertical section of said guide-frame, and Fig. 17 is a plan view or top view of said frame. Figs. 18 and 19 are detail views of a pair of receivers or holders adapted to'embrace and retain the air-pump in proper positionin the casing of the apparatus, and Figs. 20 and 21 are the respective end views of the devices illustrated in said Figs. 18 and 19.

Similar letters of reference are employedin all of the above-described views to indicate corresponding parts.

In the said drawings, A designates a suitable casing of iron or wood, which is preferably of the shape indicated in the several figures of the drawings, being provided with a back a, sides ct, and top and bottom sides a In the said back a there is a suitable arrangement of holes, as a*, for the reception of screws or nails, whereby the device can be securely attached to the side of a building or post, as will be clearly evident.

The sides and the top and bottom pieces of the casing A are preferably provided with a suitable and ornamental molding a and a cross piece or bar a connects the two sides a of the casing A in such a manner. that an opening a will be formed at the top and an opening a? will be formed in the lower portion of the front of the casing, as will be clearly seen from an inspection of Fig. 3. Said openings of and a are formed on three of their marginal edges with flanges a", on which can be made to rest the doors I) and b, as indicated in Figs. 1, 4., 8, and 9. Each door 1) and b has'a flange or lip b which fits under the edge a of each opening a and a and in the door I) is the usual form of coin-slot b and a lock I), while the door I) is provided with a lock b whereby, as will be clearly evident, 'the said doors can be securely held in their locked positions in the said openings a and a of the casing A to protect the mechanism within the said casing.

In suitable bearing-portions in the cross piece or bar a and in the back a of the easing A is rotatively arranged a main shaft 0, which projects from the front of the said piece or bar a. and has a crank a secured thereon,

as clearly indicated in Figs. 1, 2, and 4. On the said shaft 0 I have secured a peculiarlyconstructed wheel d, which is provided with a hub d and a set-screw d for firmly securing it upon the shaft 0. Said wheel (1 has a web portion (1 from the inner side of which extends an annular or circular flange 01 which, however, is eccentrically placed in relation to the central longitudinal axis of the wheel 'd. The said web (1 has an opening d in the one side thereof, which isfor the purpose of reducing the weight of metal and to facilitate the getting at the set-screw d in securing the said wheel 01 in its operative position upon the shaft 0; but said opening d is not essential and may be dispensed with, if desired. The periphery of the said wheel d is provided with a suitable arrangement of ratchetteeth d formedin the manner clearly illustrated in Figs. 3 and 5, and f is a suitable dog or pawl pivotally arranged on a pin wheel.

f, extending from the back of the said cross piece or bar a, and f is a weighted arm on said dog or pawl to cause the part f of said pawl to hang in constant sliding engagement with the peripheral surface of the said wheel d and against the ratchet-teeth thereon to permit of the forward rotary movement of said wheel, but to prevent any backward .movementof said wheel by the said part f coming in stopping engagement with the angular portion of the ratchet-teeth of the said At a suitable pointin the upper righthand portion of the periphery of said wheel at when the parts of the mechanism are in their normally inoperative positions there is a squared projection d7, which forms a suitable stop, for the purpose to be hereinafter more fully set forth. Directly back of said projection d the said wheel is provided with a pair of inclined surfaces d and d", the same forming a -shaped portion between the said projection d' and the following ratchettooth d, as will be clearly seen from an inspection of said Figs. 3 and 5. Directly back of the said wheel (1 and secured upon the said shaft 0 by means of a set-screw g between the hub d of the wheel at and the inner surface of the back aof the casing A is the hub g of asuitable cam-disk g, the purpose of which will be more fully set forth in connection with the description of the air pump or pumps. As will be seen more especially from an inspection of Fig. 8, the said back a of the casing is provided with a suitable post a, having a screw-threaded opening a Rotatively secured on a pin or screw j, screwed into the said opening in the end of thepost a is a disk e, having a circular peripheral edge portion a and an eccentrically-placed curved edge portion e a pair of diagonallyarranged portions (2 and a being provided to connect the said portions 6' and e in the mannerillustrated more particularly in Figs. 3 and 5. Secured to the said disk 6 by means of screws 6 or in any other well-known manner is a second disk 6 which is provided on its peripheral su rface with suitable ratche tteeth 6 On a suitable post or pin h is a hub h, which is provided with a downwardly-extending arm h having a finger portion 77, at its. lower end projecting at a right angle therefrom and being normally in sliding en gagement with the edge portions 6' or e of the disk 6. Said arm 71, has projecting from one edge thereof an arm it having a finger portion h, formed at a right angle at the lower end thereof and extending directly beneath the discharge-opening of a suitable coin-chute 'i, as clearly indicated in Figs. 3, 5, 6, and 9. To prevent any backward movement of the two disks e and e, I have pivoted to said arm 71, a suitably-constructed dog orpawl h",whicl1 slides over the ratchet-teeth of said disk (2 When moving in the proper direction; but which prevents any backward movement thereof, as will be understood. Pivotally arranged upon the pinj,hereinabove mentioned,

is a rod or lever 7c, which is provided at its free end with a screw lo and a roller or wheel arranged on said screw. Said rod or lever 70 is provided with a pin. or post k and the arm h hereinabove mentioned, has an eye or loop 71 the said loop or. eye and the post 70 being connected by a coiled spring m, substantially as illustrated in Fig. 3. The normal tendency of this spring m when the several parts of the mechanism are in the positions indicated in said Fig. 3 is to force the end of the upwardly-extending arm 71, directly against the stop portion of the projection d of the wheel d, with the finger portion h of the arm h in holding or locked engagement with the stop formed by the diagonal portion 6 connecting the peripheral edge portions e and e of the disk 6. At the same time the tinger portion 7L6 of the arm h5 is forced up directly against the under surface of the discharge-openin g in the coin-chute 'i, and a coin which has been dropped in the chute i will be retained therein, near the bottom, by resting on the said finger portion h? and against the inner curved surface 1" of the coin-passage within the chute, as indicated in said Fig. 3. Said spring m, connected with the arm or 1ever It, will also cause the constant operative rolling contact of the wheel or roller k with the eccentrically-arrauged annular flange d of the wheel (I. As will be seen from Figs. 3 and 5, pivotally attached tothe said rod or lever k is a suitable dog or pawl is, having a tooth k which is forced in operative engagement with the ratchet-teeth-e of the disk e by the weighted end portion 70 of said pawl. From the above description of these several parts and an inspection of said Fig. 3 it will be clearly evident that the mechanism is locked and that the shaft 0 and parts connected therewith cannot possibly be operated until the mechanism is released in the manner to be described. The said coin-chute 2' consists, essentially, of a pair of peculiarlybent plates 01 and 71 said plate 7? having suitably-spaced ribs t upon which the said plate 11 is secured by means of screws 2' to form the complete chute. Said plate 2' also has a pair of brackets i whereby the chute can be secured in position within the casing A against one of its sides a, as indicated in the several figures of the drawings, with the inlet or mouth of the coin-chute directly back of the coin-slot in the door I) and the outlet of the said coin-chute 71 directly above the finger portion of the arm 7L As will be noticed from Figs. 3, 5, 6, and 9, the said plate i is also provided with a perforated bearing portion 6 which extends directly over the edge of the plate 4? and above a slot i in said plate. (See more particularly Fig. 9.) In this bearing portion 2' and in a suitable perforation in the top (L of the casing A, I have arranged a rod '21, provided on the outside of said casing with an ornamental knob 71. The

lower portion n of said rod, as will be seen from said Fig. 9, extends below said bearing 2' and down into the said slot i in the plate '6 of the coin-chute, a portion of said rod extending into the coin-passage of the chute z. Said rod is normally held above the coin which has been deposited in the chute by a spring 02 which encircles the said rod n on that portion located between the inner surface of the top of the casing A and said bearing 1' in the manner illustrated in Figs. 3 and 5. Now as soon as a coin has been dropped into the said coin-chute t' it will be retained in the position indicated in dotted outline in said Fig. 3. By applying a downward pressure upon the knob n of the rod 71. the end a of said rod is brought down upon the edge of the coin. The latter will thus be caused to partially project from the discharge-opening in the chute 1', thereby exerting a pressure upon the finger portion h of the arm 7L5, whereby the arm 71 will be disengaged from the projection d on the wheel cl and the finger portion 71 of the arm h will be lifted away from the portion 6 of the disk 8, as clearly illustrated in Fig. 5, with the coin still retained in the position indicated in said figure. The crank connected with the shaft 0 can now be operated to turn said shaft and all the parts connected therewith. In the meantime the spring m causes the roller or wheel 70 on the arm 7a to roll against the annular surface of the eccentric projection or flange d of the wheel 61, which with each revolution of the shaft 0 and the wheel (1 causes a vibratory motion of the rod or lever 70, and hence the latter by means of the dog or pawl k produces an intermittent rotary motion of the disk 6 and disk 6 on the pin j. As soon as the highest point of the eccentrically-placed curved edge portion 6 engages the finger portion h of the arm [L3 said arm 713 and the arms 722 and 71 will be moved slightly forward, owing to a partial rotation of the hub h upon its pivotal post or pin h, whereby the finger portion h of the arm ha is brought farther away from the dischargeopening in the chute and the coin is permitted to finally drop down into the lower part of the casing A. As soon as the coin has passed from the chute v; the spring at causes the finger h4 of the arm 7L3 to rest in sliding contact on the circular edge e of the disk 6. The shaft 0 and parts thereon are thus still permitted to be operated, the said circular flange d on the wheel cl being so arranged that one revolution of the flange and wheel will cause but a partial rotary motion of the

disks

6 and 6 equal to the distance between two consecutive ratchet-teeth on said disk a These several parts of the mechanism are so arranged and timed that about fifteen complete revolutions of the shaft and wheel 61 will have caused but one complete e Z and a connecting-wall Z holding or locked engagement with the projection d on the wheel d,-with the several parts of mechanism in their normally inoperative positions and the finger portion h of the arm 71, directly beneath the dischargeopening of the coin-chute t', as indicated in said Fig. 3. second operation when another coin is deposited into the chute i.

I will now describe the manner of arranging and operating the air pump or pumps when the shaft revolves in the manner just described.

In Figs. '7 and 8 I have illustrated one manner of arranging and securing the air-pumps in their operative positions to be worked by the cam-shaped disk g, which is connected with the shaft 0, as above stated. Secured to the back a of the casing A, preferably upon suitably disposed enlargements or projections, as (1 (see Fig. 8,) is a receiver or holder section Z, to which is secured a second receiver or holder section the same being secured together in such a manner to form a socket or receiving portion in which a pump 0 is securely and operatively held. Said section Z is formed with a semicylindrical part The outer portion of said part Z is made with angular sides Z and has holes Z whereby it can be secured by means of screws upon the projection a Said semicylindrical part Z also has oppositely-extending lugs or ears Z and 1 which are provided with holes or perforations Z and directly beneath the lug or ear Z there is a curved or cut-away part 1". Connected with the said lug or ear 1 is an upwardly-extending arm Z which has a longitudinal rib Z on its inner surface, said rib terminating at a point Z on said arm, substantially'as illustrated in Fig. 18. At one side of said arm Z there may be a laterally-extending leg Z having a perforated lug l for securing it by means of a screw Z to the back a of the casing A. The said receiver or holder section Z also has a semicylindrical part Z and a connecting-wall Z and is provided with opp0 sitely-extending lugs or ears I and Z, which are provided with holes or perforations Z Directly beneath the lug or car Z is a curved cut-away part Z Connected with the said lug or ear Z is an upwardly-extending arm Z which has a longitudinal rib or projection Z terminating at a point Z on said arm, substantially as illustrated in Fig. 19. When the section I has been secured against the back of the casing A, the section Z is placed upon the section Z, (with the pump in the socket formed by the two sections,) so that the lugs or ears of the section Z will rest upon the lugs or cars of the section Z and the rib Z on the arm Z will rest directly upon the rib Z of the arm Z the two sections then being-firmly secured together by means of screws Z all of which will be more clearly understood from an inspection of Fig. 8. When secured in this manner, the respective arms Z and Z The device is now ready for a nipple 0 therein;

will have a suitablespace between them and will form a guide for a flanged roller 8, connected with a guide-frame u on each pump 0. "Each air-pump, of which there may be one, two, three, or more, arranged between a corresponding number of pairs of receiving or holding sections, may be of any well-known construction, the pump herein shown. consisting, essentially, of a main cylinder 0, having aclosed bottom 0, an air-outlet 0 and a The upper portion of each pump has an internal screw-thread-0 into which is screwed a ring 0 Movably arranged in said ring is a cylindrical tube 0 having an annular flange 0 which normally rests againstapacking-ring p at the bottom of said ring 0 to prevent the withdrawal of said tube .0 after these parts have been properly assembled. Secured to the bottom 0 of said tube 0 which is also provided with suitable air-passages e is a cap 0 and a cup-shaped washer 0 both of the usual form of construction, and between said cap 0 and the bottom of the cylinder 0 there is a spring o When all the parts hax e been put together in themanner illustrated in Fig. 12 and the tube 0 is moved up and down in said cylinder 0 against the action of the spring therein, a perfectly-operating air-pu mp is produced and the air can be forced from said cylinder 0 through the discharge-opening therein into a tube or pipe 15.

Loosely arranged in the open end of each tube 0 of the pumps is the guide-frame 11., above mentioned. Each frame is provided with a flanged portion a, which rests di rectly upon the upper flanged or beaded edge of the said tube 0 Said frame 2' is open, as at 11. and rotatively arranged on a pin u extending across said opening, is a wheel or roller u, which when the pump or pumps have been securedin the casing A is forced into operative rolling contact with the peripheral surface of the cam-disk g by the action of the spring 0 in the pump.

In order that the reciprocatory action of i the tube 0 may be properly guided when the machine is in operation and to maintain the proper alinement and operative rolling contact of the roller or rollers w against the camsurface of the disk g, each guide a has a pair of outwardly-extending and perforated ears or lugs 11. between which, on a pin 8 I have arranged the flanged rollers s, hereinabove mentioned. Said roller 8 is in alinement with the roller u, and its flanged portion 8 extends between the guide portions of the arms Z and 1, connected with the respective receiver or holder sections Z and Z", as more clearly illustrated in Fig. 7. Thus it will be evident from an inspection of Figs. 3, 5, and 7 that after the coin-controlled mechanism has been freed in the manner hereinabove set forth and the shaft 0 and cam-disk g are being revolved the action of said cam-disk against the rollers or wheels 8, connected with the pumps, is such that during each revolution of the shaft 0 two pumps are constantly forcing compressed air through the tubes or pipes t, connected with the respective pumps. As shown in the several views of the draw ings, the said tubes or pipes tare connected with a suitably-constructed valve-chest '11,.

provided with a three-way valve of any wellknown construction which has an outlet pipe or tube 1). Said pipe or tube 1 is connected with a nipple o in the bottom or side of the casing A, and connected with said nipple o on the outside of the casing, is a flexible tube or pipe v which is provided with a suitable mouthpiece i= which can be placed over the tire-valve of a bicycle for inflating the latter or over any other valve connected with some other article to be inflated with air.

Although in the present construction of apparatus I have illustrated an arrangement of three air-pumps, it Will be clearly evident that I may use but one pump, or I may employ two or more pumps without in the least departing from the scope of my present invention; and, furthermore, I do not wish to be understood as limiting my present invention to the exact arrangements and combinations of the several mechanisms herein set forth nor to the details of the construction thereof, for I am fully aware that they may be departed from without departing from the scope of my present invention.

Having thus described my invention, what I claim is- V 1.
