This inventionrelates to improvements in' combinedharness slides and snaps of the type comprising a slide to receive yand 'slidably engage the breast connection, strap, chain or snap pivotally connected to the slide and adapted to receivetheneck yoke'eyei The object of the invention is toprovide an improved combined harness slide and snap of simple, inexpensiveconstruction thatwill operate smoothly and easily, and will be strong, durable, reliable and efficient in use.

Particularly important novel characteristics of the invention residein-thespecialconstruction. of slide, the particular. connection of the slide to the attachingsnap, and in the special means provided for limiting the oscillatory movement of the slide relatively to the attaching snap, whereby. strain andwear on the parts is materially reduced, and ease of operation, strength, durability, and efliciency secured in a simple inexpensive structure.

The invention, with other objects and advantages thereof, and the particular construction, combination and arrangement of parts comprising the same, will be understood from the hereinaftercontained detail description,

whenconsidered inconnc ction with the accompanying drawings, forming parthereof, and illustrating one embodiment of the invention.

In the drawings; v Figure 1 is a side elevation of a combined slide and snap constructed in aocordancewith the present invention. I P i Fig. 2 is a top plan View. v Fig. 3 is a section on the line w a: of Figure 2, part of the attaching snap being shown in side elevation.v v a I Fig. 4 is a side elevation of a modified "construction.

Fig. 5 is a plan view of the modifiedconstruction illustrated in Figure 4, and f Fig. 6 is a section on the line; 66of Figure 5, partof the-device being shown in elevation.

While particular embodiments of the invention are illustrated in the drawings, it will ofcourse be understood that changes and variations inthe particular constructions Referring to a detailed description of the 5 5 particular embodiment of the invention illustrated in Figures 1, 2 and? of the dr awin s,] the sl de,-des1gn ated generally A,of the i evice comprises a body portion 1 rounded or curved longitudinally, and provided with side walls ormarginal flanges 2 at its under 1 side,.the structure being of channel like form to slidablyreceive within the same a breast connection. The side Walls or marginal flanges 2, whichar'e shown substantially semi-circular shape in form, are oo-extensive with the body portion 1, said flanges, or side: 7

wallsfbeing of greatest depth at the'central part of the body portion 1 and gradually'de creas ng in height toward either end'thereof.

In addition to its longitudinal curvature, the slide A is curved transversely, bein concave at underside, th'e'bottomfface 3 o the body portion 1. of the slide merging into the inner sidefaces 4 of'the sidewalls or flanges 2 in a gradual curve, the particular construction of slide shown, being especially adapted for use with a breast connection in the' form of a chain, the-structure possessing" strength and beingsuch as to prevent "binding or, cramping, and providing for free sliding'engagementof, the linksfof the chain with the s1ide,thebottom' face. 3 and the inner side faces 4 of the side walls or flanges 2 of the slide beingsmooth, andthe flanges'2 at their edges and the ends 5 of the body portion 1 being rounded, the endsof the body portion joining the ends of the flanges 2 in a gradual curve, as shown. 'At its upper side 6 the'slide has a projecting'portion or boss 7, which is provided with an aperture or bore 8 to form a bearinglooated above its bottomchain engaging 'surface "3, said boss extending transversely coextensive with the body'portion 1 and being provided with enlarged end por tions9having flat endfaces. o

The attaching snap member comprises a hook portion 10, a spring heldjpivoted tongue 11 and a shank 12. Integral with the shank 12 is a-rectangular shaped. frame'comprising spaced'side arms 13,and forward-and rear cross bars 1 1, 15, the shank ,12 connecting with the cross ,bar15. Intermediate their ends the side arms 13 have rounded enlarged apertured portions 16. Theslide A is adapted tobe arranged between the side arms 13 with -its boss 7 disposed in alignmentwith the enlarged aperto rock freely upon the rivet, the end faces ofthe enlarged, end portions 9 of the boss 7 of theslide A slidably engaging the inner side faces of the enlarged portions 16 of the side arms 13.

The rear cross bar 1 1 of the attaching snap is adapted to serve as means for limiting the oscillatory movement of the slide A in either direction relatively to the attaching snap, the same being arrangedin the path of movement of and adapted to be engaged by the outerend portions of the slide at the upper side thereof. As will be understood by changingthe point of the pivotal connection of the curved slide relatively to the cross bar or changing the size of the bar, the angle at which the slide will be stopped by the bar may be adjusted as desired.

The attaching snap including the hook portion 10, shank 12, and rectangular frame 13, let, 15, is cast or otherwise suitably formed in a single piece or unit, and the slide A preferably takes the -form of a casting.

In the modified construction illustrated in Figures 4, 5, and 6 of the drawings, the con struction' of the slide is, the same and the slide is pivotally connected at a point above its under chain engaging side to and between the side arms of the snap like in the construction, illustrated in Figures 1, 2, and 3, hereinbeforedescribed, this modified construction possessing all of the advantages of the particular construction of slide andthe special pivotal connection of the same to the snap atja point above its under chain engag ing side. In this particular instance, however, the frame of the snap is not provided with a rear cross bar or with special means for limiting the oscillatory movement of the slide, the slide being pivotally mounted closer to the forwardcross bar of the snap, and the breast chain itself depended upon to limit the oscillatory movement of the slide in the operation of the device. In Figures 5, and 6, 18 designates the slide having at its upper side the projecting portion or boss 19 to provide a bearing above its bottom chain engaging surface 20. The slide 18 is pivotally connected to the attaching snap 21 by a rivet or similar fastening member 22 extending through the aperture of the boss 19 of the slide and through the apertures of the enlarged portions 23of the side arms 24: of the frame of the snap 21. In this 'construction, the distance of the pivotal mountingof the slide 18 from the crossbar 26 of the frame of the snap 21 is such that the chain 27 will engage the cross bar 26 of the snap frame and in a way act to, limit the oscillatory movement of theslide in either direction.

' It Will be noted that by the particular construction and arrangement of parts hereinbefore set forth a combined slide and snap is afforded, which is of a simple, strong, durable, eflicient nature and which can be manufactured at low cost. The particular construction of slide and the special mounting o1 pivotal connection of the same to the attaching snap acts to secure ease and smoothness in operation, avoiding wear and strain on the parts, and the particular means provided for limiting the movement of the slide relatively to the attaching snap being of a simple, efiicient nature.
