UN TED STATES. PATENT OFFICE XELS P. NYSTR'OM, OF KOLAXD,-MINNESOTA.

TR ACE-BUCKLE.

Specification 0! Letters Patent.

Patented Aug. 4, 1908.

To all wit am it may concern:

Be it known that I, NnLs P; Xrsrnon,

' citizen of the United States, residing at Koland, in the county of Marshall and State of Minnesota, have invented certain new and useful Improvements in Trace-Buckles, of which the following is a specification.

This invention relates to harness and comprises-primarily a novel form of trace buckle, adapted for attachment to a hame-tug, back band, and belly band.

The object of the invention is to eliminate the necessit-yof providing a hole in the hame tug, whereby ordinarily the latter is weakened so that it frequently breaks at this point, and at the same time provide effective means for securing the tug to the buckle without liability of accidental detachment of the strap parts.

For a full understanding of the invention, including the advantages and operation thereof, reference is to be had to' the following detail description, and to the accompany ing drawings, in which: v V

Figure 1 is a plan view showing a buckle embodying my invention applied; Fig. 2 is a vertical longitudinal sectional view of the invention with parts of buckle arranged as when in operative engagement with the strap parts; Fig. 3 is a view slmilar to F3. 2, omitting dotted line illustration of the strap parts, however, and showing the positions of the members of the buckle when at their maximum spaced adjustment; Fig. 4 is a vertical transverse section; Fig. 5 is a side elevation partly broken away, showing thelatch device of buckle, and 'Fig. 6 is a detail transversesection partly broken away bringing out more clearly the movable connection between the buckle mcmbcrs.

Similar reference characters refer to similar parts throughout the following description and onthe several views of the drawings.

In the practical embodiment of my invention, I construct my buckle in two main parts, which for the purposes of this description will be termed relatively movable and stationary members 1 and 2 respectively. The relatively movable member 1 consists of a body provided at its longitudinal edges with side flanges 3 which are arranged adjacent to, and in the space between, similar side flanges 4 of the relatively stationary member 2. The flanges 4 of the member 2 are provlded with longitudinally mchned slots 5. Projecting outwardly from one of' the flanges 3 of the member 1 are two lugs or projections 6 which are received in adjacent slots 5 of the member 2. An elongated opening 5 in the member 2 receives a pivot fastening 7 which extends from the intermediate portion of a lever-catch 8 mounted upon the movable member 1 of the device. The catch 8 is pivotally secured at one end, as shown at 9 to the member 1, its intermedi ate portion has a sort of pivotal and loose connection at 7 with the member 2, and its lower or inner crxl portion cooperates with ratchet teeth 10, projecting outwardly from the flange 4 adjacent to which the catch is located. The operation and function of the )arts 7', 8, and 10 will appear more clearly iereinafterand it is to be noted that the lower end of the lever catch 8 projects sli htly from the adjacent portion of the buckle to provide a finger piece l1.-

At one end thereof the member 1 is provided with a loop 12 to receive the free end of the trace 13, while at the opposite end portion of the buckle, the relatively stationary so I member 2 thereof projects a short distance beyond the member 1 to form an attachment extension 14 whereby the hame tug 15 is con nected with the member 2 aforesaid. Extending from its opposite sides the member 2 is formed with integral loops 16 whcrcbythe back and belly bands of the harness are connected wit-h the buckle.

The inner adjacent faces of the members 1 and 2 are toothed or serrated longitudinally as shown at 17 to provide gripping surfaces 1 for engagement wit 1 the strap part 13. The mounting of the parts 1 and 2 relative to one another, is such that the member 1 is aila ted for a certain amount'of longitudinal shd ing movement u pon the member 2, by reason of the connections established by the projections 6, and fastening 7. The inclination of the slots 5, however, is such that in its sliding movement the member 1 is caused to move at an angle to such sliding movement and toward the member 2.

'hen the buckle is in use the free end of the trace 13 )asscs through the loop 12 of the member 1, t 1e back and belly bands being connected with the loops 16 of the member 2, and the hame-tug secured to the extension 14 of said member 2. In order to effect the relative longitudinal or clamping movement of the members 1 the lever catch 8 is moved toward the extension 14 of the buckle. and rides in engagement with the ratchet 10 projecting from the latter. The members 1 and 2 are thus locked in firm clamping engagement with the trace 13 received therebetween, and since the trace passes through 5 the loop 12, it will be seen that the tension or strain thereon presses the member 1 toward the member 2 and increases the gripping en- 'agement of the buckle with the trace, the atter of course being suitably adusted in the o cration. henever it is desired to release tl i e strap part clamped between the members of the buckle it is only necessary to manipulate the catch 8 disengaging the same from the ratchet teeth 10 and thereby unlocking, so to speak, the members 1 and 2 and ermitting free relative movement thereof ongitudinally and away from one another.

The various advantages of the invention will be recognized upon reference to the foregoing description of the construction and operation thereof.

Having thus described the invention, what is claimed as new, is:

1. A buckle comprising relatively movable and stationary members, means connecting said members together and ada ted to effect cooperative clamping action tJOl'GOf when moved, and means for automatically locking the members in clamping posit-ion after operation thereof.

2. A buckle comprising complemental members, connecting means between the members for causing clamping cooperation thereof when actuated, a pivoted catch for :3 operating the members; and locking means engaging the catch for holding said members in clamping osition after operation thereof.

3. In com ination with a strap part, a buckle comprising complementa-l members,

connections between the members permit tin longitudinal relative movement thereof,

and for causing clampin movement of the same when forced toward one another to engage the stra part, and a catch connected with one of t 1e members and engaging the other of the members to lock the parts in clamped position when operated.

4. A buckle comprising relatively movable and stationary members, the stationary member being provided with longitudinal inclined slots, projections extending from the movable member in the slots of the stationary member whereby said members are with the movable member, and pivotal connection between the middle portion of said catch and the stationary member, and

ratchet teeth carried by the stationary memher for locking cooperation with the opposite end of the lever catch in the manner specified.

5. buckle comprising relatively movable gripping or clamping members, connecting means therebetween, a strap engaged by said members, and locking means for causing clamping action of the clamping members and holding the same in clamping position.

In testimony whereof I alhx my signature in presence of two witnesses.
