11 Claims.

This invention relates to pin holders suitable for commercial and domestic use where the basting of fabric materials requires the use of many pins.

The primary object of the invention is to provide an improved pin holder which includes mechanical means for feeding and positioning the pins during basting operations.

A specific object of the invention is to provide a pin holder with an automatic feed means for advancing pins to an ejection position, and a manually operable means to manipulate a pin from that position into a position suitable for insertion into fabrics during basting or similar operations.

A further object of the invention is to provide an improved pin holder of simple construction which is readily operable by one hand of the worker during basting of fabrics or in other types of operations requiring the use of a plurality of pins.

Another object of the invention is to provide an improved pin holder which, due to its few parts, is susceptible to inexpensive manufacture.

With the foregoing, and other objects in View, the invention resides in the following specification and appended claims, certain embodiments thereof being shown in the accompanying drawings, in which:

Fig. 1 is a partially sectioned view in perspective of the invention;

Fig. 2 is a partially sectioned end elevational View of the invention;

Fig. 3 is a partial view in perspective of the ejection end of the invention;

Fig. 4 is a sectional plan view of the body portion only of the invention taken along the line 44 of Figure 1; and

Fig. 5 is a rear elevational view of the invention.

Referring more particularly to the drawings, the pin holder referred to generally at I consists of two main parts, a body 2 and an ejector plate 3. The body 2 is preferably formed by die casting a plastic material such as Bakelite; however, it is obvious that other materials such as metal would be equally suitable. The body 2 is provided with an opening 4, the purpose of which will hereinafter be described. Adjacent the opening 4 on either side of the body 2 are bosses 5 having underlying arcuate grooves 6. The body 2 is formed with a longitudinal slot 1 running from the loading end 8 to the ejection end surface 9 where it is joined by a transverse slot It] in the body 2. The slot 1 is of such design as to accommodate a plurality of pins H in sideby-side arrangement with their fiat heads being received in the circular channel portion 12. It is to be noted that the slot 1 is formed on both sides of the opening 4 so that the upper and lower sections of pins II are held against lateral movement with respect to the body 2 when they are inserted at the loading end 8.

A resilient means, preferably a heavy rubber band !3, is used to automatically move the pins ll toward the end surface 9 after a leading pin is ejected from the body. This band [3 is first engaged with one of the grooves 6 in a boss 5 after the body has been loaded with pins. It is then passed around the last pin I4 through the opening 4 and looped over the other boss 5 to engage the other groove 6. Thus, as can clearly be seen in Fig. 4, a considerable amount of force may be applied to the pins to move them toward the left, or the ejecting position.

The length of the channel I and the position of the bosses 5 as well as the strength and length of the band 13 will determine the amount of pins to be effectively accommodated by this pin holder. Thus the body 2 may be longer to accommodate more pins. The bosses 5 may be located further to the left when viewing Fig. 4 so that less pins will be left in a dormant position between the points 15 and H3 in the body 2 when the band l3 has advanced pin M to the point 16.

The body 2 is formed with an elongated arcuate portion l! which consists of a substantially circular head It joined to the body 2 by neck portion IS. The neck portion I9 defines a recess 20 between the shoulder 2| of the body 2 and the head I8. The neck portion l9 also defines the inner surface of a groove 22 on the rightside of the body as viewed in Fig, 2. The outer surface of the groove 22 is defined by the rib 23.

The ejector plate 3 is preferably formed from a single piece of metal having superior resilient qualities. The upper end of the plate 3 is formed to engage the head [8 of the elongated portion ll of body 2. The end 24 of plate 3 is placed in groove 22 and the plate is then sprung over head l8 until the indented portion 25 is received in recess 20 of the body 2. It is to be noted that the arcuate portion 26 of the plate is spaced from the upper edges of head 18 for a purpose hereinafter described. It should also be noted that the indented portion 25 of the plate 3 occupies only a portion of the recess 20.

The plate 3 is provided at one side with an ejector member 21 extending transversely to plane defined by the plate. The member 2'! is provided with an inclined portion 28 for engaging the pins II. The lower portion of the member 21 is recessed at ll when the plate 3 is formed to provide an ofiset portion 29 which serves as a pin stop during operation of the mechanism. The end of the body 2 is recessed at 30 to accommodate this ofiset member 29 as seen in Fig. 3. The member 21 is provided with a slot 3| through which a pin 32 extends to limit the outward movement of the plate 3. The pin 32, as shown in Fig. 4, extends from the exterior of body 2 through the slot 3| of the plate, and the rear section 33 of slot it] into the body at 34. This pin may be press-fitted into position or may have a threaded engagement at 34.

Adjacent to and leading into the section 33 of slot is a cam surface 35 which is engaged by a similar cam surface 36 on member 21 during an operation of the device.

The complete operation of the invention will now be described. A plurality of pins, either in connected strip form or otherwise, are loaded into slot I at loading end *8. The first pin loaded abuts the surface 9 and the remainder fill the slot 1. The rubber band !3 is then looped over one boss 5 to engage a groove 5, and is then Wrapped around the last pin Ill through opening 4 to engage the groove 6 in the other boss 5. The operator may then grasp the holder by placing the thumb against the body 2 and the fingers against the spring plate 3. Upon the application of pressure, the plate 3 is moved inwardly until cam surfaces 35 and 36 engage each other. Upon the engagement of these two surfaces, further pressure will move the plate 3 and consequently the member 2'! inwardly and downwardly. The downward movement is permitted by the spaced relationship between the arcuate portion 26 of the plate and the upper edge of the head It as well as by the relative size of recess 20 to the indented portion 25 of the plate.

The angular portion 28 of member 2! engages a pin in the transverse slot I0 and will rotate the first pin about its head as an axis. As the pin is under the tension of resilient band 13, the depending pin stop member 29 which is provided on member 21, prevents the said pin from being projected out of the access opening 31 provided in the end of the casing. When the pin has been rotated to the position shown in Fig. 2, it will be seen that, due to the cam action of surfaces 35 and 35, the heel portion 38 of member 21 has moved downwardly over the head 39 of the pin to firmly engage the shank thereof at 40 the other side of the shank being firmly engaged against lower wall 43 of slot Ill. The lower surface 42 of the member 21 at recess M then firmly engages the head 39 of the pin to hold it in the circular portion I2 of channel 1.

With the pin thus extending at right angles from the body a basting operation may be made. The fabric so engaged by the pin acts through friction to dislodge the pin from the holder after pressure on the spring plate 3 has been released and the member 21 has moved back to the normal position as shown in Figure 1; the holder I as a whole being moved longitudinally of the pin and in a general direction opposite to that used to insert the pin in the fabric.

Thus it is seen that the invention provides an improved holder and manipulator for pins which is simple in construction and which is easily handled when it is desired to place pins in fabrics undergoing basting operations.
