I rrvo'rnn-roiveun SNAP-HOOK.

Be it known citizen of the that I, J OHN United States, residing at Watervliet, in the county" of Albanyyan'd State f of New York, have invented certain new and useful Improvements' in Pivotedof which the followtherein to the accompanying drawing p ,This 1nvent1on rel tes to lmprovements in certain novel features of construction, and in the peculiar arrangement and combination 3 of its parts, as will be fully herein after described, and defined in the claims. The invention has more particularly to dealwith pivoted spring is utilized for retaining thetongue in looking engagementwith the hook proper, and the improvements include novel means of connection for the severalparts, compriswhereby 7 the device 1s easy-to manufacture, and is form of rendered more durable and eflicient in operation,-and. whereby the parts are more readily coupled together, while permitting of their detachment, as desired.

In the accompanying draw ngs forming a part hereof, I have shown convenient em-- bodiments of the invention, for the purpose of illustration, and in the said, drawings, Figure 1 is a bottom plan viewof the snap hook, Figs, 2 and 3 are longitudinal and transverse sectional views Figs. 4; and '5 are detailviews'of a modified tongue, Figs. 6 and 7, are detail ,views of still another modified form,of

the hook, and forming a shoulder against I:

which a portion of the tongue member, presently to be-described, engages when in normal position. Arranged forwardly of said shoulder 8 is a transverselyextending slot 4 in the body portion of the hook, the transversely extending wall 43 constituting a pivotal bearlng for. the tongue member, The

- under surface ofthe body portion 1 is'reduced at said bearing part, asindicated in 2, thesaid reduced portion connecting With, the opening textending through said body portion. It is obvious,of'course, that the bearing 4?, which forconvenience may be termed a bearing bar, may be formedby placing abar in the body portion of the opening 4, However, the preferred construction resides in forming said bearing bar integral with the body portion of the hook; a

hook at a point intermediate the ends of the The tongue member comprises an elongated body portion 5j'adapted at its forward end to engagewithinthe-reduced part 2 of .the hook terminal, and having projectingdownwardly from its sides adj acent'its said forward end, suitable ears 6, which if the tongue is stamped from sheet metal, may be formed: by bending. down the projecting preferably widened toward its rear end, as

The tongue is gal,

shown "at 7, and said widened part-has a downwardly extending upright wall 8 of a theends of the slot 4: and

v point immediately adjacent the shoulder 8?. The upright portion 8 of the tongue is conveniently of .heightin excess erator when the device is in use. Projecting downwardly from the upright portion 8 of the tongue isa'tail or lip 9 adapted to be curved about the bearing bar a and rest 1 within the plane of theouter surface of saidbody part 1.

1 The spr ng memberispreferablyU-shaped comprising an elongated bearing arm 10 adapted to engage the inner surface of the' tongue and rest between the downwardly projecting ,sideears 6 of the latter, and

having aheelpart 11 adapted to rest in the recess formed by the opening 4 of the body portion 1 of the hook, and which said body portion 1 of the hook.

Either the bearing rod 4, or the tail 9 of the ton ue may be provided;

with a recess therein of a Width slightly in excess of the Width of the spring member at the bend 15 thereof, but preferably both of said parts are provided Withfa recess," that in the bar 4? being indicated by the 41 and that in the tail "of "the tongue by the reference numeral 9*. The-spring at its bend is mounted upon the "bearing bar 1 at said recessed part 4*, and beneath the tongue at said recess 9?. In the 'spring is conveniently placed u-pon the bearing bar -and in engagement beh-ind the shoulder 13; as is obvious, when the tongue is applied with its recessed part overlying the bend of if the tongue is formed of sheet metal as is lpreferred the tail "thereof upon being inserted through the slot 4 "is bent about the bearing bar 4*. The recessed i parts 4 and 9 in the bearing bar and undue binding or contacting action between the spring "and the tongue, in the operation of the latter. Projecting d'oWn-Wardl from the tongue are oppositely disposed lugs or pro-v the spring member, and preferably of a length to "overlie both arms of the spring. "These arms 'constitute guides for the spring, and prevent unnecessary la'teral play of the rlat-' 10 ter, and they are conveniently of bendable metal and adapted to be bent or. curved to constitute "with the tail 9 of the tongue position Will be substantially flush With the outer surface of said Wall, as shown. In applying the parts the s wing is first applied to the bearing bar as be ore, when the body portion of the tail of the tongue Will be bent rearwardly about the bearing bar, and the slitted lugs of the tongue bent tliorwardly about the bearing bar, and preferably overlapping 'theterni inal of the body portion so as to constitute a substantially closed bearing .to engage the bearing bar.

in that embodiment of the invention illustra'ted in Figs. 8, 9 and 10, the forward Wall 3 of the loo'p is substantially flush with vthe body portion 1, and the tongue when in position rests at its rear end 20 upon -said Wall 3. The body portion 1 of "the hoo'k is provided avithan opening 21 separated a transversely extending hearing bar 22, and *proj eoti-ng downwardly from the inner surface of the tongue are two pairs I of "lugs, conveniently of bendable metal, said lugs being arranged one pair upon each side of the spring. v One lug of each pair is arranged to bend or curve about the bearing bar forwardly of the latter, and the other lugof each pair is adapted to be curved or bent about said bearing bar rearwardly of the latter, as is clear, and the "respective lugs of each pair constituting a substantially continuous bearing extendaround the bearing rod, and lying 'Within the plane of the outer surface of the "body portion 1, as shown.

In each oftt'h'e embodiments, it Willbeap preeiated that the bearing point for the tongue is adjacent to and "preferably is the same bearing point "for the bend of the spring with the result "that the spring :is more efiicient operation, and the retaining action thereo fmore readily "overcome in the "operation of the tongue. Again, the conabout thebearing bar 4 as shown, whereby 1 g p struct'ion is very "advantageous where a a substantially continuous or closed pivotal short book is desired, "the improvements being equally applicable to hooks of various sizes. It .Willalso be o'bservedthatth'e par ticular connection for the tongue consti- "tutes an effective retaining means for the latter, sincea substantially closed bear'ing is provided, and also a part or parts of said 1 5 bearing onstitute "in effect a housing or guide engaging'overthe sides of both arms of "the spring :andypreventin'g any undue lateral play of the latter. Should it be desiredto'separatethe 5pafts, it is only 'necessary-torebend the tail of 'the 'tongue and thecc'operating oppositely disposed lugs '01 projections, when "the tongue in ay be readily lifted from engagement with the body por- "tion of the hook, and When the-springwill he free for removal, as is obvious.

llaving thus described the inventi6n,=what I"clain as new and 'desireto secure by Let- 'ters Patent is: 1.' Ina snap'hoolga body part having a 4'5 b'earing engaging about -the rod 4". v

"In Figs/4t, 5, "6 and 7 is shown a "slightly modified form of construction in which the {forward wall '3 of the loop part "of the device is reduce'd at 16 to constitute the bearing Iodorbar forthe tongue. In this embodiment of the invention, "the body p'ortionof the hook is provided with an open ing '17 therein forwardly of said b'earing bar, and the tongue'is preferably formed'of 65 a single sheet of metal with the tail 18 thereof slitt'ed to form one or more bendable lips or lugs 19 topa'ss through the jopening 1-7 inthe body portionof the hook 'and engage around the bearing bar 16 in 6011 direction opposite to that of the body portion of the tail '18 "which passes rear- Wardly about said bearing bar. 7 The body portion of said tail of the tongue constitutes in effect a continuation-of the 'Wallof '65 the shoulder 3, since the *same when in hook at one end, a transversely extenda ing bearing bar atits opposite end, a substantially U-shaped spring mounted at its bend on said bearing and engaging at one end the hook member and at its opposite end the tongue, the tongue being formed of bendable material and having a tail-piece bent about and under the bearin bar, and also having integral elongated at fingers projecting at a point intermediate its sides, a

one fingerbeing at each side'of the spring with the fiat'surface thereof bent forwardly of and under the bar. a a
