1 Claim.-

This invention relates to a machine for wrapping coins and more particularly to one adapted for use in theaters, mercantile establishments and banks where it is desired to package a stack of coins of the same denomination in predetermined quantities to be easily and quickly exchanged for a bill of equal value.

One of the objects of the present invention is to provide a simple and practical device of the above character which will be strong and durable yet simple and practical inconstruction.

A further object is to provide a coin wrapping machine which will be very inexpensive to manuiacture as it has few parts which may be easily and quickly made and assembled.

A further object is to .provide a device capable of easy and quick adjustment to handle coins of diilerent size.

A further object is to provide a machine which will permit the coins to be tightly wrapped, thereby to permit subsequent handling of the rolls of coins without danger of unwrapping and loss.

Other objects will be in part obvious from the annexed drawing and in part hereinafter indicated in connection therewith by the following analysis of the invention.

metal, glass or plastic but a metal stamping as shown in Figure 4 is preferable, as it may be easier made. If thin stock is used, a strengthen- This invention accordingly consists in the fea- I tures of construction, combination of parts, the

unique relation of the members, and in the relative proportioning and disposition thereof, all as more completely outlined herein.

To enable others skilled in the art to fully comprehend the underlying features of the invention, that they may embody the same in various modifications in structure and relation contemplated by the invention, a drawing depicting a preferred form has been annexed as part of this disclosure, and in such drawing like characters of reference denote corresponding parts throughout the views, in which- Figure 1 is a side elevational view of the coin wrapping device;

Figures 2 and 3 are opposite end elevational views in section onthe lines.2--2 and 3-4, respectively; and

Figure 4 illustrates the blank from which the case is formed.

The coin wrapping machine includes generally a base it! adapted to rest on a desk or table having upturned ends II and -82 the latter bein slightly higher, thereby to support two rollers l3 and I4, preferably in slightly inclined position to better stack the coins while being wrapped. The base may be of any suitable material such as ing upturned flange I5 may be advisable.

The rollers are preferably covered with a com position suitable to coact with the coin wrapper without slippage similar to the rubber covered paper feed rolls used on a typewriter although other means may be used to urge the paper into proper relation with the other parts. The rolls are each provided with a bearing pin is at the lower ends and a similar axle ll at the upper ends. The pins i6 engage any one of a series of openings or holes l8 in the end wall ll while the pins ll may be dropped into any one of the series of openings or notches 20 at the top of the other end wall i2 as shown.

A central stud is mounted in the end wall H and for convenience of manufacture may be an internally threaded" sleeve 2| closed at its outer end :and held in place on the wall II by a screw bolt 22 as shown in Figure 2. This abutment or stud is mounted midway between the rollers and slightly thereabove so as to engage the end of the stack of coins as they are placed on edge on the rollers. The closed end oi the stud is about the size of a dime so as to have a relatively large surface contact with the lower coin faces regardless of the size or denomination of the coin.

Heretofore, it may have been attempted to adjust a part corresponding to this stud vertically with respect to the center of the stack as the denomination was changed, but it is now found that much better results are obtained in the tightness of the wrapped package which is most important, by moving the axes of the rollers laterally away from each other. Thus, if the rolls are close together, as is desirable, to package dimes, radial lines from the coin center to the points of tangency between the edge of the coin and the supporting rolls should be about Accordingly, when half dollars are to be wrapped, it is desirable to separate the rolls to obtain substantially the same relative position as when wrapping dimes.

Such a construction as herein described accomplishes several desirable results. For instance, if the rolls are close together and one attempts to slip the wrapper beneath the edges of a stack of half dollars, unless great care is used, the roll or stack of coin will spill oil the rolls especially if the paper is of the usual stillness. One the other hand, if the rolls are relatively wide apart and one attempts to package dimes, then it is very diiflcult to feed the wrapper down under and up over the other roller. When the points of tangency are as above described the paper feeds more easily around the stack of coins to the best advantage to be grasped by the operator to tightly roll the coins.

each side of the center plane whereby the sup' porting rollers may be moved laterally with respect to this center plane to accommodate coins of a difierent size. For instance, the rollers would be mounted on the inside openings when rolling dimes, in the middle openings when rolling quarters and in the outer holes or openings of the series when packaging half dollars, or coins of approximately that size.

While openings are shown in these end plates as probably being the easiest and cheapest to manufacture and operate, it would doubtless ocour to any mechanic that other forms or means for adjusting the rollers laterally with respectto the center plane could easily be evolved.

The operation will, of course, be clear to those familiar with the subject. However, it may be stated that when packaging dimes for example, the rollers are adjusted to a position where they are closest together and a stack of fifty dimes is placed upon these rollers with their faces parallel to the central stack or abutment. A wrapping paper 23 is then slid under the stack of dimes 2A and above one of the rollers, and between the stack and the other roller, and the inserted end of the wrapper is turned over the top of the stack of dimes while the wrapper is fed, thus to provide several thicknesses of paper around the stack, after which the free end of the wrapper is crimped down around the upper end and the abutment which holds the stack away from the end plate provides suflicient paper at the opposite ends of the wrapper to be crimped over that end when the stack is removed.

It will thus be seen that the present invention provides a simple and practical coin wrapping machine which may be easily and quickly adjusted and operated to provide a tightly wrapped package which may be safely handled in the manner first above described.

What I claim is:

A coin wrapping machine comprising a base including upstanding, spaced apart, first and second walls, a relatively fixed abutment projecting centrally from said first wall toward said second wall, the first wall below said abutment having lateral series of openings, corresponding openings of each series being the same lateral distance from a vertical line intersecting said abutment, the second wall having notches in its
