HINGED SPLIT FOLLCWER.

SPECIFICATION forming part of Letters Patent No. 679,947, dated August 6, 1901.

Application filed August 22, 1899.

To all whom it ma concern."

Be it known that I, JEREMIAH F. COLLINS, of Brockt-on, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Hinged Split Followers, of which the following is a specification.

This invention relates to an improvement in hinged split'followers; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described, particularly claimed, and clearly illustrated in the drawings.

Figure 1 represents in side elevation a hinged split follower constructed in accordance with my invention. Fig. 2 represents a top plan view of the same. Fig. 3 represents a perspective View of the same, one of the forepart sections being removed to show the arrangement of the parts. Fig. 4: is a detail sectional View taken in a line passing through the heel and between the two sections of the fore part. Fig.5 represents an end elevation of the heel-section and its attached tube-hinge. Fig. 6 represents a cross-sectional view on the line 6 6 of Fig. 1 looking toward the heel 1. Fig. '7 is a detail perspective view of the end of one of the fore-part sections, showing the recess in which and the recessed pintle about which the tube-hinge is arranged. Fig. 8 represents a horizontal longitudinal section of the follower on the line 8 8 of Fig. 1 looking in the direction of the arrow. Fig. 9 represents a perspective view of the heel member of the hinge. Fig. 10 is a perspective View of a preferred form of the heel member of the hinge.

This invention relates to an improvement in hinged split followers, and particularly that class of hinged split followers shown in United States Patent No. 626,366, granted to me June 6, 1899.

The present invention has for its object the simplification and improvement in the hinge members by which the movement of the heelsection and fore-part sections are regulated and controlled.

1 represents the heel section, and 2 2 represent the companion fore-part sections.

3 represents the hinge member that is connected to the heel-section. This, as shown in Fig. 9, is in the form of a tube having a fiat face 4, formed with a rib 5. The rib 5 Serial No. 728,046. \"No model.)

fits in a complemental groove 6 in .the heel section, (see Fig. 3,) and the member 3 is secured to the heel-section by a screw 7, the rib 5 serving to keep the member 3 from twisting, as will be evident from an inspection of Fig. 3. The member 3 upon the side opposite the rib 5 is formed with a slot 8, having cam-faces 9 9 and an enlargement 10. Each fore part (see Fig. 7) is formed with a tubular pintle 11, arranged in the member 3. The pintle 11 has a central recess 12 to receive the opposite ends of a spiral spring 13. A circular recess l-t is formed between the pintle 11 and the adjacent wall of the section 2, in which the member 3 is arranged to slide. (See Fig. 8.) A finger 15 is secured by a screw 16 to each of the opposing spaces of the sections 2 2, said fingers being properly located in a countersunk recess opening into the circular recess 1 The ends of the fingers 15 project across the circular recess let enlarged and arranged in a recess 20 in the other section 2, limits the distending action of the sections 2 2.

The parts being constructed and arranged as shown, when it is desired to remove the follower from a boot or shoe the heel-section is swung upward to shorten the follower. This movement ofthe heel-section turns the member 3 about the pintle 11, causing the camfaces 9 9 to engage their-respective fingers 15 15, thus forcing the two sections 2 2 toward each other against the action of the springs 13 and 16 The swing of the heel thus shortens and contracts the followers. When the follower is in operative position, the fingers will be in the enlargement 10, (see Fig... u and 5,) while when the heel-section is thrown up the fingers 15 15 pass from the cam-faces 9 9 to straight faces 21 21, by which the two sections are held contracted, owing to the action of the springs against the fingers, until the heel-section is swung down. The camfaces maintain the sections dental expansion.

-VVhile I prefer to move both sections 2 2 by means of the hinge, I do not wish to be understood as limiting my invention to such a construction, as I may move but one part through the action of the hinge.

In I ig. 10 I have shown a. preferred form of hinge. Instead of the hinge being cast, as shown in Fig. 9, I form the hinge out of a piece of metal stamped into shape, the said hinge being provided with extensions 40, provided with screw-holes 42. The form of hinge shown in Fig. 10 is applied to the parts of the follower substantially in the same manner as 2 2 against accithe form shown in Fig. 9, with the exception that instead of the screw 7, used in the form of hinge in Fig. 9, I employ pins passing down through the last in the Way commonly employed for securing the leaves of hinges in the respective sections.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it maybe made or all of the modes of its use, I declare that what I claim is- 1. Ahingedsplit'followercomprisingaheelsection, a sectional distensible fore part, a hinge member connected to the heel part and formed with a slot, complemental inclined cam-faces formed upon opposite lower walls of said slot, complemental holdingfaces formed upon opposite upper side walls of said slot, a finger upon each sectionof saidfore part and each finger arranged in said slot whereby the fore part may be contracted by the engagement of the fingers with the camfaces and held in contracted position by the engagement of the pins with the holdingfaces.

2. A hinge member for split followers comprising a tube, a single recess formed in said tube having an enlarged lower portion and a reduced upper portion, the side walls of one being arranged at an angle, to the complemental side walls of the other and forming, in efiect, a broken continuation thereof.

In testimony whereof I have affixed my signature in presence of twofwitnesses.
