STOP FOR MULTIPLE OPERATED FASTENER CLOSURES Filed July 29, 1951 Patented May 23, 1933 UNITED STATES PATENT OFFICE GUSTAV JOHNSON, OF WEST BOXBUBY, MASSACHUSETTS, ASSIGNOR TO UNITED-CARR FASTENER CORPORATION, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS STOP FOR MULTIPLE OYERATED FASTENE'R' GLOSURES Application filed July 29, 1931. Serial No. 553,772.

My invention aims to provide improvements in multiple operated fastener, closures and particularly improvements in end stops constructed to permit removal of theslider when desirable.

In the drawing which illustrates preferred embodiments of my invention Figure 1 is a plan view of one end of a pair of stringers closed by multiple operated fasteners, my improved stop members and a slider being shown in normal use;

Fig. 2 is a view of the parts shown in Figure 1, but showing the slider in cross-section and in engagement with the end stops;

Fig. 3 is a view of the parts shown in Fig. 2, but showing the manner in which the slider may be removed;

Fig. 4 is an enlarged section taken on the line 4-4 of Fig. 2; and

Fig. 5 is an edge view of the stop having the pivoted, part carried thereby.

My invention is particularly useful in connection with multiple operated fasteners and is more specifically directed to improvements in so-called top stop members which normally prevent the slider from pulling entirely free from the fastener members secured to stringers. In connection with multiple 0perated fasteners, it has been found desirable to permit removal of the slider from both stringers for various reasons. In some instances it has been found that the sliders have become damaged and therefore it is necessary to remove the damaged slider and replace it with a new one.

Referring to the particular combination of elements illustrated by the drawing, I have shown portions of a pair of stringers 1 and 2 to adjacent edges of which are attached the usual series of separable fastening members 3 in combination with a suitable slider 4 for engaging and disengaging the fastener members 3. Adjacent to the upper end of the series of fastening members 3 on the stringer 2 I have attached a simple U- shaped sheet metal member 5 clamped to opposite sides of the stringer adjacent to the inner edge thereof and secured thereto by rivets 6, as shown in Figs. 1 and 4. This member 5 is of suitable dimensions to permit passage through'the slider 4. On the other stringer 1 I have also secured a U-shapcd member 7 substantially identical with the member 5 secured to the stringer 2. To this member 7 I have pivotally secured, to one of the rivets 6, a stop member 8 which is also U-shaped in cross-section and conforms with the member 7. This member 8 is so shaped and arranged that when it is in the position shown in Fig. 1 the loop portion 9 thereof may enter the slider (Fig. 2) so that the upper edge of the slider may contact with the shoulder 10, thereby limiting the upward movement of the slider relative to the fastener members 3. It will be seen from an inspection of Fig. 2 that when all the fastenin members 3 are engaged and the slider is 1n its furthermost normal posi tion when the fastener members 3 are engaged there are a number of the fastening members 3 located within the slider 4. Therefore the fastening members cannot accidentally become disengaged when the slider is in that position.

If it becomes necessary to disengage the slider entirely from the installation the stop member 8 may be swung about its pivot 6 from a position shown in Fig. 2 to a positlon shown in Fig. 3. This removes the shoulder 10 to a position where it will not prevent manipulation of the slider into a position shown in Fig. 3, thereby permitting the member 5 to be removed laterally from the slider and thereafter tipping and moving the slider upwardly to remove it from the member 7. The tipping and upward movement of the slider relative to the part 7 is necessary because the part 8 prevents sufiicient upward movement relative to the part 7 to permit lateral removal. It is obvious that unless there is suflicient relative movement some of the fastening members 3 will remain within the slider and under such conditions it would be impossible to remove the slider by a straight sidewise movement.

While the pivotifor the part 8 is arranged insuch a manner that the upper edge of the slider engages the shoulder 10 at apoint with relation to the pivot, that upward movement of the slider tends to hold the part 8 in the position shown in Figs. 1 and :2. However, I have provided a sort of snap fastening means to hold the member 1n the position shown in those figures. This snap fastening means'is provided partly by a sort of head 11 "(Figs 2 and 3) formed adjacent to the folded over portion of the part 7 and partly by forming the portion 9 of the member 8 so that it will snap over the head 11, as best shown in Fig. 4. This bead 11 extends only part way along the folded portion of the member 7 so that it will not interfere with the removal of the slider, as shown in Fig. 3. The bead 11 also serves as a guiding means to regulate the tipping action of the slider when being engaged with and disengaged from the member 7. It will be noted from an inspection of Fig. 2 that the member 5 engages the last fastening member 3 of the series secured to the stringer 1 when the fastening means is entirely closed, thereby aiding in holding the fastening members within the slider in interlocking engagement and preventing disengagement until' such time as the member 8 has been moved to the position shown in Fig. 3 when it is intended to permit passage of the member 5 laterally from the slider. In this manner any jam which would prevent the slider from moving toward the opening end of the installation can be corrected by merely pulling the fasteners apart by hand after the member 5 has been pulled outwardly from the slider. Thereafter the slider may be moved to the opening end of the installation where it is ina position to be 'moved toward the closing end, thereby automatically bringing together in the proper manner the fastener members 3 on each stringer. The so-called stop member 5 is not in fact a stop member but is provided more or less for the purpose of having a symmetrical installation. The member 5 is further useful because it is readily adapted to pass outwardly laterally through the slot in the side of the slider.
