COLLAR AND HAIVIE AND FASTENING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 610,792, dated September 13, 1898.

Application filed 11 1897.

signed as an improvement on the hames illus trated and described in Letters Patent No. 234.,519, granted to me November 16, 1880.

The objects of the present invention are to improve the locking mechanism at the lower end of the hames, whereby the looking or unlocking may be effected from either side of the joint, and to improve the adjusting devices between the upper and lower sections of the hames.

lVith these and other objects in view the invention consists of the several details of construction and combination of parts, as will be hereinafter fully described, and particu-" larly pointed out in the claims.

In the drawings, Figure 1 is a sectional front view of a collar and hames constructed in accordance with my invention. Fig. 2 is a detail perspective view of the lower portion of the hames closed. Fig. 3 is a similar view showing the hames open. Fig. 4 is a crosssection through one of the hames where the upper and lower sections are connected. Fig. 5 is a perspective view of the locking-pin decached.

Similar reference-numerals indicate similar parts in the several figures of the drawings.

1 indicates the collar, which may be of any suitable material and is divided at its lower end but unbroken at its upper end. The two hames are hinged together at their upper ends and are detachably connected to the collar by bolts 3. Each hame is formed of two sections,the upper sections being indicated by 4. and the lower sections by 5. Each section is tubular and preferably heart-shaped in cross section, and the upper sections are adapted to fit within the lower sections and be held in the required position relatively to each other by means of set-screws 6. In this manner the length of the hames can be adjusted to suit collars of different lengths.

Serial No. 642,294. (No model.)

Instead of being heartshaped in cross-see tion the tubes may be of any cross-sectional shape other than circular, the purpose being to prevent the two sections from turning relatively to each other.

- Each of the lower sections 5 is provided at 1 its lower end with a plate portion 7, against which plates the lower ends of the collar abut, and when the hames are closed these plates will closely engage each other and there will be no open space at the lower end of the collar. Each of the sections 5 is provided on its lower face adjacent to its lower end with an elongated slot 8, and this slot is enlarged, as indicated at 9, at the end most remote from the lower end of the section.

10 indicates a latch which is pivoted on a pin 11, secured in the lower section 5, and this latch has an enlarged end which fits in the enlargement 9 of the slot. The latch is provided at its forward end with a hook 13, and a spring 14, preferably spiral, is seated between the inner face of the enlarged end 12 of the latch and the opposing inner face of the hame, and the parts are so arranged that when in their normalposition the latch will lie in the slot 8 and be flush with the outer surface of the hame. A latch is' pivoted in each section 5, as above described.

16 indicates the locking-pin, which is provided midway its length with a flange 17, and this flange is beveled on each side and its periphery thereby brought to a knife-edge.

The bores in the lower ends of the sections 5 are countersunk, as indicated at 18, to receive the flange 17 in order that when the hames are closed the flange will not interfere with the two sections 'making a close joint. The pin is provided near each end with a recess 19, which recesses are adapted to receive the hooks 13 on the latches 10. The forward end of each latch 10 is beveled, and the corresponding end of each slot 19 is similarly beveled, as indicated at 15, and these beveled surfaces are adapted to engage and prevent the forward end of the latch being forced inwardly too far by the force of the spring 14. The pin is also provided near each end with recesses 20 to receive the ends of set-screws 21, which are tapped into the hames, and the vious that hames made in accordance with my present invention can be unlocked at their lower ends from either side, and this arrangement enables the hames to be used on either the near-side or off-side horse and it will not be necessary to go between the horses in order to unlock the hames. This is a great practical improvement upon the device illustrated in my former patent, referred to above, for when made in accordance with that patent the locking device had to be made right and left hand, and a further disadvantage of the old construction in practical use has been that the rigid tongue would frequently break, and the hames be thus rendered useless. In my present invention the pins,which will be made of forged steel, will not be liable to break, and even should one break it can be very easily replaced. The manner of adj ustment vertically between the two sections in the present invention is also an improvement over the threaded connection between the two sections, as shown in the patent, for in practice it was found that the lower section would turn upon the upper section when draft was applied to the hames. This objectionable feature is entirely overcome by my present construction.

It will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described the invention, I claim 1. In a fastener for hames and the like, the combination of separate sections having their meeting end portions made tubular, alongitudinally-curved pin having an annular flange midway of its ends to engage with the meeting ends of the tubular sections and limit the movement of the pin when thrust therein, and adapted to have its end portions make detachable connection with the tubular ends of the said sections and be concealed thereby, and catches applied to the tubular ends of the aforesaid sections to make positive engagement with the end portions of the pin and secure the parts when in working relation, substantially as set forth.

2. The combination of a pair of tubular hames hinged together at their upper ends and having the bores at their lower ends coun tersunk, of a pin having a flange midway its length, the sections of the pin on opposite sides of the flange being adapted to fit in the lower ends of the respective hames, and the flange to fit in the countersinks of the bores, said pin having a recess near each end, and a pivoted latch in each hame, said latches having hooks to engage in the recesses in the ends of the pin, substantially as described.

The combination with a pair of tubular hames hinged together at their upper ends and having the bores at their lower ends countersunk, of a pin having a flange midway its length, the sections of the pin on opposite sides of the flange being adapted to fit in the lower ends of the respective hames, and the flange to fit in the countersinks of the bores, said pin having a recess near each end, a setscrew in each hame adapted to engage the pin and lock it against withdrawal, and a spring-actuated pivoted latch in each hame, said latches having hooks to engage in the recesses in the ends of the pin, substantially as described.

4. In combination, hames pivoted together at one end and adapted to be separated at the opposite end, the separable ends of the sections being tubular and provided with vertically-extending plates, a collar separable at one end and adapted to have the separable ends abut against the plates provided at the separable ends of the hames, a pin having a flange midway of its ends and adapted to have its end portions removably fitted within the tubular ends of the hames, catches applied to the said tubular ends of the hames and adapted to positively engage with the end portions of the pin and connect the parts, and other fastenings between the end portions of the pin and hames for positively connecting them, substantially as set forth.

In testimony that I claim the foregoing my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES E. BERRY.
