CHANGE-MAKER.

-- Specification of Letters Patent.

Patented July 1c, 1915.

Application filed May 5, 1916. Serial No. 95,580.

To all whom it may concern."

Be it known that we, MAX C. BRUHN and Gnonon F. MCGILL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Change-Makers, of which the following is a specification.

This invention relates to a holcler'and dispenser of coins for making change, and the principal objectof theinvention is to pro vide a new and improved construction, combination and arrangement of 'partsfor accomplishing the desired result. I

In the drawings, Figure 1 is a frontelevation with parts broken away, of a change maker constructed in accordance with the principles of our-invention; Fig. 2 is a sectional view; Fig. 3 is a sectional view taken on line 38 of Fig. 2; Fig. 4: is a sectional view taken on line H of Fig. 2; Fig. 5 is a plan view of a portion of the operating mechanism; and Fig. 6 is a perspective of one of the operating mechanisms.

In the present invention, the numeral 1 designates generally a casing which-may be made of'any suitable material such as metal or wood, and in the present form the casing is provided with a removable front 2,

having a hinged top 3 which is held in place by a spring catch 4 at one or both ends of the casing.

Supported by the casing are a plurality of coin-holding tubes of difierent sizes, each opened on one side and adapted to contain coins or checks of difi'erent sizes. These tubes are rigidly supported by the casing and are inclined from the vertical, as shown more clearly in Fig. 2, with a rounded portion 6 adjacent the bottom of each tube bent at a slightly diflerent angle, more nearly upright than the remainder of the tube. Ihis rounded'portion 6 also conforms more nearly to the curvature of the coin for whichthe particular tube is designed and intended.

At the bottoms of the tubes 5 is a plate 7 for supporting the stack of coins in each tube. The inclination of the tubes from the vertical position takes some of the weight of the stack of coins from the bottom plate so that no matter how high the coins are plate 7, and consequently on the bottom coin, will not be excessive. This bottom plate 7 is formed between the sides of each tube with a notch 8 from the center of which extends a curved slot 9. A shaft or pin 10 is secured to the bottom plate 7 and depends from the plate at approximately the center of curvature of the slot 9. Pivoted on the pin is an ejecting member 11 pressed upwardly against or in the direction of the plate 7 by means of a spring 12 which is held on the pin 10 by nuts 13 or other suitable fastening means operable also to adjust the tension of the spring. A

At the rear of each coin tube 5 is a slot 1 1 in the bottom plate 7. Through this slot extends one arm 15 of a key-lever 16- which is pivoted on a shaft 17 mounted below the coin tubes in brackets 18. The other arm 19 of each key-lever extends through a suitable gaged to press the arm 15 of the key-lever to the rear of the slot 14. I

Each projecting member 11, as shown more clearly in Fig. 5, is provided with an irregular slot 23 which extends at an angle to the slot .14 in the bottom plate 7 but crosses it, so that the extremity of the-arm 15 of the key-lever 16 also extends through the slot 23 of the ejecting member. Projecting upwardly from the ejecting member 11 through the slot 9 of the bottom-plate 7 is an ejecting projection 2a which is cut away at the rear, as designated by the numeral 2 5, and as viewed in Fig. 6, so that in the forward movement in the slot 9 the projection 24 will engage the rear of the lowerm'ost coin because of theyielding action of spring 12 which tends to press the ejecting member 11 upwardly against the bottom plate 7. Also extending upwardly from the front of each ejecting member 11 and forming an integral part thereof is a project-ion 26. the top of which'is in the plane or just above the plane of the top of the bottom plate 7. At the rear of this projection 26 is an inclined portion 27 which extends below the .top of the bottom plate at all times. The normal position of this projection 26 is in the notch 8 at the front of each coin tube, substantially in front of the slot 9. The object of the projection 26 is to engage the lower and outer edge of a coin positioning it in the tube by tipping the front of the coin outwardly, thus insuring that it rests directly upon the top of plate 7 so that the rear of the coin will be in position to be engaged by the ejector 2% upon its forward movement. Without this projection 26 it might happen that if there were only a few coins, or only a single coin in the tube it might have tipped downwardly at the forward side of the coin and therefore the ejector in moving forwardly would fail to engage the rear of the coin and hence would not eject it; but by providing a pro ect on 26 at the front of each coin tube the coins are positively positioned and properly held upon the bottom plate for engagement by the ejector 24.

I11 order to prevent the ejection of more than one coin from each tube upon a single operation of the ejector, a detent plate 28 (see'Fig. a) is attached to the lid 3, which has projections 29 extending downwardly to a point above the top of the bottom plate 7;, depending upon the thickness of the coin for which the tube directly opposite any one of the projections 29 is designed. 7 These projections 29 permit the dispensing of a single coin but prevent more than one coin from being ejected from. the tube at the same time.

Arranged at the front of the tubes 5 and within the casing 1 just below the cover 3 is an inclined hute 30 which extends through an opening at the end of the easing fordischarging the coins into another chute 3 1 attachable to the outside of the easing. This chute 31discharges the coins into a receptacle 32 preferably in the form of a shallow-dish, from which they-are easily removable. This receptacle 82 may be made removable-by providing it with a bracket 33 into which a tongue 84 secured to the chute 31 extends. At thebottom of the chute 81 or secured, to the receptacle 32 is a bridge 35 extending substantially the width of the chute 31 to engage and prevent coins from rolling down the chute thuscausing them to slide into the receptacle so they will not jump over or out of it.

The arrangement of the chute 31 and receptacle 32 is optional, depending upon the place in which the change maker is used. The specificconstruction above'described is particularly adapted for use in connection .all or any of the key-levers may be depressed at the same time. Upon the return of the ejecting member not only will the ejector 24 pass vertically under the stack of coins without disturbing them, because of the pressure spring 12, but also all of the coins, and particularly the lowermostcoin of each chute will be pro erl 'posititned by the projection 26 of the ejecting member so that the lowermost coin willbe positively placed and held in position for engagement by the e ector upon its next fprward movement. If the coins become clogged in any of the tubes 5, in the chute 3O, or if it is desired to insert or remove coins from the tubes 5 it is necessaryenly to raisethe cover 3 by disengaging the latch 4t and to manipulate the coins as desired. i We claim: I I r v v 1. In a change maker, a coin tube and a bottom support for a stack of coinsin the tube, and a movable ejector pivoted at one side of the coin stack for "engaging the lowermost coin in one direction of movement, yieldingly supported for depression below the lowermost coin in the other direction of movement. l v
