9 Claims.

My invention relates to an improvement in pins, wherein it is desired to provide a pin having a body designed to lie fiat against the material pierced thereby.

Because of the fact that common pins are usually straight throughout their length, flexible sheet material pierced by a pin at two spaced points must be bent to some extent to admit the pin. The straight body of the pin also makes it necessary for the sheet material to be folded or bent considerably during insertion of the pin. Where the pin is used to connect flexible sheets lying upon a flat surface, or the like, it is dinicult to fold or bend the body to insert the pin. For example, in pinning a pattern to a piece of cloth laid upon a table, the insertion of the pins necessitates the lifting of the two sheets and flexing of the sheets to admit the pin.

Attempts have been made to curve pins so 'that they may be inserted without flexing the sheet material. Such curved pins have the disadvantage of producing a bulge between the points of insertion of the pin. In other words, the portion of the pin intermediate the pierced points of the material curves away from the sheet material, thus a bulge is ordinarily formed in the sheet materials where the pin has been inserted.

It isthe object of the present invention to avoid previous difiiculties with pins by providing a pin which is bent to producea substantially straight center section and inclined ends thereupon. One of these inclined ends is pointed,

while the other of the inclined ends is used as a handle. This type of pin has the obvious advantage of lying closely adjacent the sheet material pierced between the points of pierce and permits the sheet material to lie flatterupon the table or other supporting plane, than has been previously possible.

A feature of the present invention lies in the provision'of a pin having a straight center section and an inclinedpoint extending angularly therefrom. This point is of suflicient length to provide a guide so that the person using the pin will know at what point the material should be pierced for the second time, In piercing the material it is thus common practice to insert the point through the material to a depth at which the center portion of the pinhas started to pivot through the opening, whereupon the pin may be pivoted so as to start the second piercing operation. By having the pin constructed in relatively straight sections which are formed in angular relation, one part of the pin may provide a guide for the next section thereof.

A further feature of the present invention resides in the provision of an enlarged handle at tached to, or formed by the handle end of the pin; so as to simplify the insertion thereof. This handle end provides a simple means for engaging the pin and for accomplishing the insertion thereof.

A further feature of my invention resides in the fact that the pin may be constructed double, if it is so desired, so that two parallel pinsmay be used in place of a single pin. Such a construction has several advantages. In the first place, the connecting means between the two handle ends of the pins forms a means of grasping the pin assembly and of operating the same. In the second place the two pins naturally will hold the two or more sheets of material being connected more firmly than would otherwise be the case. In addition to these advantages the pin assembly thus constructed will not tilt when inserted through the sheet material.

A further feature of my invention resides in the fact that my pin construction may be provided with a cork screw shaped handle, and which may be used to support a flower or the like. My pin construction may also be embodied in the shank of a safety pin, so that the shank of the pin will lie flat against the pierced sheet material.

These and other objects and novel'features of my invention will be more clearly and fully set forth in the following specification and claims.

My pin A, illustrated in Figures 1, 2, and 3 of the drawing comprises an elongated pin body or shank III, which includes a central section I I', and an angularly extending piercing section I2, provided with a piercing point I3, and a handle portion I4. The piercing portion I2 and the handle portion I4 extend angularly with respect to the central portion I I and are preferably in the same plane. The extremity of the handle portion I4 is curved at I5 to provide a handle anchor.

The pin A includes a handle I6 formed of plastic or other suitable material which embeds the anchoring end I5 of the handle portion I4 of the pin. This handle member I6 is shown in the form of a flat disc, but may be of any desired shape to provide a suitable handle for the pin shank III. The curve I5 in the handle end I4 prevents the pin body from pulling away from the handle member l6.

In Figures 4 and 5 of the drawing, I disclose a pin B, which is virtually identical with the pin A. The pin B includes a pin body or shank I! which includes a central straight portion I9, a pointed piercing end 20, and a handle end 2|. The handle end 2| and the piercing end are preferably in a single plane, as illustrated in Figure 5. The extreme end 22 of the handle end 2I is flattened or otherwise deformed to provide an anchor for this pin end.

A handle member 23 is provided to embed the flattened end 22 and adjacent end of the anchoring portion 2| of the pin II. In the form shown, the handle member 23 comprises a disc of plastic or other suitable material, but this handle may be of any desired shape to operate effectively.

In Figure 6 of the drawing, I disclose a pin C, which is similar in operation to the pins A and B. Tie pin C includes an elongated wire shank 24 which includes a central straight portion 25, a piercing point section 26, and an anchoring end 21. The anchoring end 21 continues to form a spiral handle 29, which is formed of the material forming the pin bent into a spiral shape. This spiral head or handle provides a simple means of engaging the pin and holding the pin during the use thereof.

The pin D is illustrated in Figures '7 and 8 of the drawing. This pin D is similar in operation to the previously described pins, but is provided with a double shank. The pin D is formed of a wire body or shank 30, which includes a central connecting portion 3| which is connected by connecting elements 32 to angularly inclined portions 33. The angularly inclined portions 33 merge into the central substantially fiat portions 34 which bend into the piercing portions 35. The connecting portions 32 extend in parallel relation, as do the inclined portions 33, the straight portions 34, andthe piercing portions 35. Thus, both of the piercing points enter the sheet material to be pinned at the'same time and the pin is inserted to the same depth.

In Figures 9 and 10 of the drawing, I disclose a pin E, which is particularly designed for supporting a flower or the like, but which may be used for many other purposes. The pin E includes a central straight portion 36 from which merges an inclined piercing portion 31 and an inclined handle portion 39. A helically-shaped or corkscrew-shaped end 40 is provided with a piercing point 4 I' which may be threaded into the body of a flower or the like in the same manner in which a corkscrew is threaded into a cork. After the flower has been attached the pin may be inserted through the lapel of a coat or through a garment, the straight portion 36 lying on the underside of the lapel, or on theinside of the garment flat against the surface thereof. The lapel of the coat, or the supporting garment need not be curved or bulged by the fastening pin.

The safety pin F, illustrated in Figure 11 of the drawing, also embodies the principles of my invention. This safety pin is formed of a strip of spring wire, such as 42 which at one end 43 is enclosed within a safety pin head 44 formed of flat material. Adjacent the end 43 is provided the rear side 45 of the pin, which continues into the helical spring end 46. An inclined portion 41 emerges from the spring 46 and this inclined portion 41 is connected to a flat portion 49 which in turn is connected to an upwardly inclined portion 50. The upwardly inclined portion 50 is provided with a piercing point 5I, which maybe used to pierce the sheet material when disengaged from the safety pin head 44. As the con-' struction of the head 44 is very similar to that now in use, the exact detail construction thereof is not described. Needless to say, this head forms a channel to receive the pointed end 5| of the pin. In operation, the shank of the pin is inserted through the sheet material by forcing the pointed end, such as I3 on the piercing point portion I2 of the pin through the sheet. After this portion I2 of the pin has been forced through the sheet material, the pin is rotated to some extent so that the portion I2 underlies the sheets of material. The second piercing operation is then started so as to force the piercing point I3 up through the material. The portion I2 is of sufficient length to guide the pin back through the material at a point properly spaced from the handle end I4 so that he piercing points through the material are properly spaced. I have found that ordinarily the piercing point portion I2 should be slightly shorter than the center portion II so that the piercing point I3 may move forwardly to a slight degree along the undersur- 7 face of the material before the piercing operation starts. I have found that if the portion I2 of the pin is as long or longer than the central portion I I, the point l3 will pass through the material at a point spaced from the first point of pierce slightly greater than the length of the portion I2. Accordingly in such a case, the center portion I I is not long enough to properly connect the points of pierce without bulging the material to some extent.

In Figure l, the pin is shown in position extending through the cloth 52 and the pattern 53 laid thereupon. It will be noted that the center portion II of the pin closely engages the undersurface of the material sheet 52.

In accordance with the patent statutes, I have described the principles of construction and operation of my pin, and while I have endeavored to set forth the best embodiments thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
