Jan. 10, 1967 M R. HUTCHINS SECURITY STRUCTURE FOR A COIN METER Filed June 30, 1965 INVENTOR.

MAR LY N R HUTCHINS A TTORNEVS United States Patent G1 ice 3,297,123 SECURITY STRUCTURE FOR A COIN METER Marlyn R. Hutchins, Spring Lake Park, Minn, assignor to Andrew P. Simon, doing business as Pak Distributing (30., Spring Lake Park, Minn.

Filed June 30, 1965, Ser. No. 468,545 7 Claims. (Cl. 194-97) This invention relates to protective shield means for coin storage containers and more particularly to security structure in combination with the housing of a coin operated meter for protecting the coins stored in the vault section of the meter.

Coin operated meters are widely used with self-service machines as laundry washers and dryers, car washers, amusement and vending machines and other electrically operated devices. The character of the market locations of these machines vary widely from conservative safe locations to tough problem locations where abnormal theft conditions prevail. In the problem locations a profitable business cannot be attained because of excess vandalism.

The design of a conventional coin operated meter is not particularly suitable to prevent theft of the coins stored in the meter. The conventional coin operated meter is relatively easy to pry open with simple hand tools, as the meter housing has openings and edges suitable for bearing surfaces and fulcrum points for the hand tools. The security structure for a coin operated meter of this invention obviates these disadvantages of the conventional coin operated meter.

The object of the invention is to provide improved security structure for a coin operated meter which eliminates openings and exposed edges to establish maximum protection for the coin chute and money box.

Another object of the invention is to provide security structure in combination with the housing of a coin operated meter which has a safe and attractive appearance and does not interfere with the use and operation of the coin slide.

Still another object of the invention is to provide security structure for a coin operated meter which permits easy access to the coin box yet provides maximum security for the coin box.

A further object of the invention is to provide security structure usable in combination with coin operated meters having different sizes and shapes.

Still a further object of the invention is to provide security structures for coin operated meters which can readily be installed in the field on operating meters with a n1inimum of time and labor.

An additional object of the invention is to provide a relatively simple and sturdy security structure for a coin operated meter which is strong in construction, reliable in use, and pleasing in appearance.

The exact nature of the invention as well as other objects and advantages thereof will be readily apparent from the consideration of the following specification relating to the accompanying drawing in which:

FIGURE 1 is a fragmentary perspective view of an automatic laundry machinehaving a coin operated meter equipped with the security structure of this invention;

FIGURE 2 is a fragmentary plan view of the meter and security structure of FIGURE 1;

FIGURE 3 is a sectional view taken along the line 3-3 of FIGURE 1;

FIGURE 4 is a sectional view taken along the line 4-4 of FIGURE 3; and

FIGURE 5 is an enlarged sectional view taken along the line 5-5 of FIGURE 3.

Referring to the drawing, there is shown in FIGURE 1 3,297,123 Patented Jan. 10, 1967 an automatic machine indicated generally at 10 equipped with a coin operated meter 11. The machine 10 is an automatic unit such as a laundry washer, laundry dryer, car washer, amusement device, vending machine and similar electrically operated devices. The coin operated meter 11 has a timing mechanism which is actuated in response to monetary coins for controlling the operation of the machine. The machine 10 together with the meter 11 are normally used by the public on a self-service basis with a minimum of supervision. This exposes the coins stored in the meter to vandals and thieves. To minimize the theft of the coins stored in the meter security structure indicated generally at 12 is attached to the meter to eliminate openings and edges used as bearing surfaces and fulcrum points for hand tools of vandals and thieves.

The machine 10, shown in fragmentary form in FIG- URE 1, has a flat top wall 13 integral with an upright side wall 14 The coin operated meter 11 is rigidly mounted on the top wall 1-3 flush with the side wall 14. In some instances the coin operated meter may be mounted on the side wall 14 or the front wall (not shown) of the machine.

The coin operated meter 11 has a box-shaped metal housing 16 enclosing a coin actuated timer mechanism and defining a coin vault. The housing 16 comprises a flat top wall 17 integral with laterally spaced side walls 18 and 19. As shown in FIGURE 3, a front. wall 21 having a peripheral forwardly projected flange 22 is secured by spot welds to the forward end sections of the top wall 17 and the side walls 18 and 19. The forward edge of the peripheral flange 22 is flush with the ends of the walls 17, 18 and 19 positioning the front wall. 21 rearwardly or behind the ends of the side walls 18 and 19'.

As shown in FIGURES 3 and 4, the front wall 21 has a rectangular opening 23 accommodating a coin box 24 located in the vault section of the housing defined by a horizontal petition 26 and a vertical petition 27. A lock mechanism 28 attached to the center portion of the front wall 29 of the coin box 24 is used to lock the coin box to the vertical petition 27. The coin box 24 has an open top for receiving coins from. a coin chute 31 projected through and secured to the front wall 21 above the open ing 23. The coin chute 31 includes a. coin transporting slide 32 having coin receiving openings 33 used to align the coins in the coin chute so that the coins can be moved into the housing 16 and stored in the coin box 24 after actuation of the timer mechanism of the meter.

The security structure 12 is used in combination with the housing 16 to provide maximum protection for the coins stored in the vault section of the meter 11. As shown in FIGURE 1, the security structure 12 comprises a heavy inverted U-shaped strap indicated generally at 34 having upright fiat legs 36 and 37 disposed adjacent the opposite sides of the housing side walls 18 and 19. The flat leg 36 projects below the bottom of the housing 16 so as to cover the linear opening between the bottom of the housing 16 and the machine top wall 13. The bottom end of leg 37 rests on the top wall 13. As shown in FIGURE 3, legs 36 and 37 project forwardly from the front of the housing 16 to form protective side extensions on opposite sides of the coin box 34. The forward extension of the fiat legs 36 and 37 is indicated by distance 38. The inverted U-shaped strap 34 has a flat top wall 39 integral with the top edges of the upright legs 36 and 37 covering the forward portion of the top of the housing 16. As shown in FIGURE 2, the front section of the top wall 39 has a cutout forming semicircular wall 41 providing access to the coin receiving openings. The opposite ends 42 of the semicircular wall 41 are rounded to eliminate sharp and abrupt edges.

The inverted U-shaped strap 34 is secured to the side Walls 18 and 19 by bolt and nut assemblies 4-3, projected inwardly through suitable holes in the fiat legs 36 and 37 and housing side walls 18 and 19. The detailed use of one bolt and nut assembly 4 3 is shown in FIGURE 5 and comprises a bolt 44 having a semispherical head 46. The bolt 44 projects through a hole 47 in the strap leg 36 and through a hole in the housing side wall 18 into the value chamber. The head 46 is located in a countersunk recess 4 8 having a diameter substantially equal to the diameter of the head so as to minimize the exposed edges between the head and the outer face of the flat leg 36. A nut 49 is threaded on the inner end of the bolt 44. and cooperates with the 'bolt 44 to firmly clamp the leg 36 to the housing side wall 18.

To further prevent the prying and dislocation of the coin box 24 a heavy flat plate 51 is secured by bolt and nut assemblies 52 to the outside of the box front wall 29. As shown in FIGURES 3 and 4, the plate 51 has a width and height larger than the opening 23 in the housing front wall overlapping the side, top and bottom portions of front wall 21 forming the rectangular coin box opening 23. The plate 21 has a width substantially equal to the transverse distance between opposite sections of the peripheral flange 22 and a bottom edge positioned in a contiguous relationshi with respect to the machine top wall 13 as as to minimize openings and edges suitable for bearing surfaces and fulcrum points for hand tools used by vandals and thieves. The nut and bolt assemblies 52 are mounted in the same manner as the nut and bolt assembly 43 in FIGURE 5 so as to prevent access between the bolt heads and the outer face of the plate 51.

In summary, the security structure 12 is used in combination with the block shaped housing 16 of the coin operated meter 11 to eliminate access openings and exposed edges usable by hand tools to pry open the coin chute 31 and/or coin box 24. The security structure 12 includes an inverted U-shaped strap 34 projected forwardly from the front of the box. The strap 34 embraces the top and sides of the meter housing 16 to act as a shield and armor enclosing the coin vault of the meter. The top wall 39 of the strap has a semicircular edge 41 providing an access opening to the coin receiving openings 33 of the coin transporting slide 32 and thus does not inhibit the use or operation of the coin slide. The front of the coin box 24 is reinforced with a heavy plate 51 having a peripheral section overlapping the front wall 21 of the housing;

While there have been shown, described and pointed out the fundamental novel features of the invention as applied to a preferred embodiment, it is to be understood that various omissions, substitutions, changes in shape and details of the security structure illustrated may be made by those skilled in the art without departing from the spirit of the invention.
