page_text: the lever is closed. The spring H is rivetted at P to the side of the body and
extends outward in the proper position so that when the lever is closed, the lug O
passes over the spring and engages behind it, thus holding the lever securely in place.
In order to unfasten the lever, the spring is pressed downward as indicated by the full
and dotted lines in Fig. 2 thus allowing the lug O to swing over the spring and the
lever to be swung outward in which position the hook I may be disengaged from the
pivot F. The free end of the lever is provided with a suitable projection or thumb
piece which facilitates its disengagement from the spring H. A lug may be cast
on the body to prevent the spring H from swinging too far inward when the parts
are unfastened.
It will be understood that the pivot F may be engaged with any one of the
hooks I I so as to secure the proper adjustment of the hame to the collar.
As indicated in Fig. 5 the spring H is secured in place on the side of the body by
the lug or lugs R against which the edge of the spring bears, the spring being held
in place by the rivet P. The lug R is cast on the inside of one of the bars
of the slotted body, which is also provided with a recess which permits the spring to
be bent away from the slotted lever.
As indicated in the drawings the hooks D D' on the ends of the body and the
toothed strap are made of a peculiar form being bent or curved spirally, and the
spiral portion projecting laterally on one side of the longitudinal axis of the body or
strap as shown most clearly at Ď Fig. 2 by which device I am enabled to mould the
hooks without a core, and the hooks thus made possess a further advantage, in that they
are not as easily detached from the eye on the hame as those heretofore made while,
if desired, they may be closed down on the eye so as to attach the body or strap
permanently to the hame as indicated by the dotted lines in Figs. 1 and 2.
By this invention I am enabled to construct hame fasteners in a cheaper manner
than has been heretofore practised and also secure greater durability and effectiveness
or freedom from accidental detachments whereby accidents are prevented.
It will be observed that the free end of the spring H projects beyond the lever,
so that it can be readily bent out of engagement with the lug on the lever. The
spring retains the lever in place in the body and prevents its falling out when the
strain of the horses pulling is released. It will be observed that the relative positions
of the pivots G G and pin F are such that the strain of the draft forces the body
inward toward the collar, and holds the parts together.
By this construction I am enabled to produce a hame-fastener, which will remain
locked on the collar when the hames are applied with sufficient tension, without the
retaining spring, but by the use of the spring, the device is kept locked even when
carelessly attached or when the horse is backing or going down hill.
Having now particularly described and ascertained the nature of the said.
invention and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, I wish it to be understood that several of the
features herein set forth being already known, no claim is made to such features
separately but only in the combinations as set forth. I claim ;-
1. The combination with the slotted body A, having hook D the toothed strap C
provided with hook D₁ the slotted lever B pivotted in the ends of the slotted
body and provided with pin F of the retaining spring H adapted to retain the lever
in the locked position, substantially as described.
2. The combination with the toothed strap C provided with hook D¹ the slotted
lever B pivotted in the ends of the slotted body and provided with the pin F and
the spring H by which the lever is secured to the body of the slotted body A having
hook D and provided with cross bar J substantially as described.
3. The combination with the toothed strap C having hook D¹ the slotted lever B
pivotted in the ends of the slotted body and provided with pin F of the slotted
body A having hook D and provided with cross bar J adapted to engage with one
of the teeth of the strap to prevent its disengagement from the pin of the slotted
lever substantially as and for the purposes set forth.

page_text: 4. The combination with the slotted body A having hook D and the toothed strap C
provided with hook D₁ of the slotted lever B pivotted in the ends of the body on the
pins G G having collars L L' on their extremities substantially as described.
