This invention relates to an improved pin particularly a safety pin of the type used in laundries and generally known as laundry pins.

Pins of this type are used in laundries to hold mesh bags and the like in closed position. The mesh or other fabric used in the bag becomes entangled with the coil, clasp and other portions of the pin with the result that time is wasted in disentangling the pin and the mesh or other fabric is frequently damaged. The conventional type of shields or guards sometimes provided on safety pins do not prevent the coarse mesh from becoming entangled in the coil, clasp and other portions of the pin.

It is an object of the present invention to provide an improved pin of the above character which overcomes the difiiculties heretofore encountered and will not become entangled with the mesh or other fabric.

A further object is the provision of an improved guard -or shield for a safety pin such as a laundry pin which will serve as a positive stop and which is so formed as to prevent the material with which the pin is used from passing beyond the guard.

Among other objects is the provision of an improved safety pin such as a laundry pin having a positive guard or shield which is relatively simple and inexpensive to manufacture, which will not damage or injure the fabric with which the pin is used and which is sturdy and rugged and will give satisfactory service over a long period of time with comparative freedom from wear.

In the drawing Fig. 1 is a perspective view of a pin embodying my invention showing it applied to a mesh laundry bag.

Fig. 2 is a side View of the pin in open position,

Fig. 3 is an end view from the coil end of the pin showing it in open position, and

Figs. 4 and 5 are sectional views in the direction of the arrows 4-4 and 5-5 on Fig. 2.

My invention resides in the improved type of guards and shields which are applied to the pin together with the structure whereby the guards are combined with the pin.

Aside from the improved guards or shields the pin illustrated in the accompanying drawing is a conventional type of laundry pin which is similar to a large safety pin. The pin is made from a single strand of resilient wire and is formed with two arms 5 and l integrally connected by the spring coil 8, the arm 1 being formed with the point 9 at its free end and the arm 6 being formed with clasp H) at its free end so as to be adapted to engage with the pointed end of arm I.

' between closed and open positions.

The clasp ll] is the conventional shielded clasp made of sheet metal wrapped around the end of arm 6, as shown, and formed with a trough shaped catch H along its opposite or lower edge in which the pointed end of arm 1 rests when the pin is closed. Spring coil 8 is so formed that arms (5 and l are normally held in divergent position when the pin is open as shown in Fig. 2. The pin is closed in conventional manner by squeezing the two arms together until the pointed end of arm I rests in the catch H. The pin and clasp should either be made of a material which will not rust or corrode, or they should be plated or otherwise suitably coated to prevent discoloration ef the laundry.

Adjacent the two ends of the pin I provide the shields or guards l2 and I3 to prevent the fabric from becoming entangled with the coil or the clasp-and also to prevent the material from passing over the coil and clasp onto arm 6. Each of the guards takes the form of a flat plate disposed transversely of the two arms and they may be made of suitable material that will not rust or corrode or they should be suitably plated or coated as in the case of the pin itself.

Guard l2 is positioned adjacent to and blocks access to coil '8 and projects laterally beyond the two sides of the arms 5 and l and above the arm 6 and below the arm 1 when the pin is in closed position. It is provided with an aperture l4 through which arm 6 passes and with a slot 15 for accommodating arm 1. Slot I5 is preferably disposed at an angle as shown so as to conform with the normal movement of arm 1 as it shifts The guard is suitably held in position as, for instance, by being spot welded, brazed or soldered to arm 6. The guard may be conveniently made by a stamping operation.

Guard 13 is positioned adjacent to and blocks access to the clasp and it projects laterally beyond the arms 6 and I and above arm 6 and below arm I when the pin is in closed position. It is provided with an aperture 16 to accommodate arm 6 and with a tapered or generally triangularly shaped slot ll to accommodate arm 1. Slot I1 is of such a size to permit arm 1 to move sufficiently both in an up and down direction and in a lateral direction so that it may be shifted between open and closed positions. Guard 13 is also suitably held in position on the pin as by means of spot welding, brazing or soldering.

The guard-s may be assembled on the pin during the process of manufacturing the pin prior to the attachment of clasp l0.

The pin is used in the conventional manner, that is, point 9 is passed through the fabric or other material while the pin is in open position and the material is gathered on arm 1. Thereafter, the pin is closed and as shown in Fig. 1 the guards form positive stops preventing the material from becoming entangled with either the coil or the clasp or from passing beyond the coil and clasp onto arm 6.

It will thus be seen that I have provided an improved pin which may be used as a laundry pin and which prevents entanglement of the fabric or other material with the pin, which will not damage or injure the fabric and which may be used by an operator without any special skill or training. Modifications may be made in the illustrated embodiment of my invention without departing from the invention as set forth in the accompanying claim-s.

I claim:

1. A safety pin including a pair of arms resiliently connected to each other adjacent one of their ends, a clasp mounted by the opposite end of one of said arms, a trough portion forming a part of said clasp to receive and releasably retain the adjacent end of the second arm, and a guard comprising a plate extending substantially transversely with respect to the pin axis and mounted by and against any movement with respect to said one arm at a point immediately adjacent the clasp carried by tie latter, said plate being formed with a tapered recess disposed in line with said trough portion and defining betwen its edges a space in excess of the transverse area of said portion, said recess being flared in the direction of the second arm and extending to the edge of said plate.

2. A safety pin including a pair of arms resiliently connected to each other adjacent one of their ends, a clasp mounted by the opposite end of one of said arms to receive and releasably retain the adjacent end of the second arm, and a guard comprising a plate extending substantially transversely with respect to the pin axis and mounted by and against any movement with respect to said one arm at a point immediately in advance of the point of connection of said arms, said plate being formed with a slot extending through to its edge and projecting ang-ularly in the direction of movement of the second arm; said slot permanently receiving said second arm.

3. A safety pin including a pair of arms resiliently connected to each other adjacent one of their ends, a clasp mounted by the opposite end of one of said arms, a trough portion forming a part of said clasp to receive and releasably retainthe adjacent end of the second arm, a guard comprising a plate extending substantially transversely with respect to the pin axis and mounted by and against any movement with respect to said one arm at a point immediately adjacent the clasp carried by the latter, said plate bein formed with a tapered recess disposed in line with said trough portion and defining between its edges a space in excess of the transverse area{ REFERENCES CITED The following referenlces are of record in the file of this patent:
