My invention relates to spring tongued snaps.
The object device of this class which is new, novel,
practical and of utility; which may be men ufactured in a variety of sizes and shapes; which will comprise an interchangeable tongue and clamping member; which may be quickly and cheaply which will be positive in action; which will be durable; which will be relatively inexpensive in manufacture; which will permit of application use; which will be eiiicient in accomplishing all the purposes for which it is intended.
In spring tongued snaps of present manufacture, in so far as this applicant knows or can ascertain, no means is provided for the quick and cheap replacement of broken springs or spring tongues. A broken spring usually results in a discarding of the snap and all. of its In my device all snaps of a given size are provided with interchangeable spring tongues and clamping means making it possible to quickly and cheaply replace those broken or Worn out thereby saving the loss of the other parts.
With these and other objects in view as will more fully appear, my invention consists in the construction, novel features,and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in theaccompanying one-sheet drawing, of which,
Figure 1 is a perspective view of my device, showing the removable tongue and tongue clamp;

of my inventionis to provide a replacedif broken;
' it is also understood that the drawings are i of the snap to various forms of parts and replacement with Like characters of reference parts in all the figures.
It is understood that various changes in the form, proportion, size, shape, weight and other details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of my invention and without sacrificing any of the advantages thereof; and
to be interpreted as being illustrative and not restrictive.
A practical embodiment of. the invention as illustrated in the drawings comprises: i
A snap hook member 1, having an upwardly and backwardly curved hook end portion 2, culminating in a lip 3. Said member 1 is provided with a shank portion 4-, which in the position as shown in Figure 1, has upon its upper forward side edge portions a pair of curved'upstanding parallel lugs or guides 5. The fist floor 6 of the channel thus formed betweenthe said lugs 5, lies in a plane which, extended toward said lip 3, passes above the under surface of said lip.
Rearward from the said lugs 5, shank 4:, is disposed the clamp -7.
Said clamp 7 is preferably stamped and die out from sheet metal, is formed in an inverted U shape, has a fiat top 8 and two downstanding side portions 9. Said sides 9 are adapted to fit the sides of the said shank 4 and together with said shank 4 are alin'ed- 1y perforated as shownat 10, for the insertion therethrough of a removable holding upon said designate like meansl-l; i V
A flat tongue 13, of spring metal, 1s provided, having an upturned end portion shownas 14.
The said top 8 of the clamp 7 is provided with a slot 12 for seating the said upturned end liWhiCll may be a rectangular perforation as shown in the drawings, or a rectangular notch in the edge of said top 8, if desired.
In usual assembly the said spring 13 is disposed within the channel formed between thesaid lugs 5, its rear end portion clamped V by clamp 7 to theshank 4, with holding means 11, therethrough. The upturned end 14 of the spring 13 is engaged by the said slot 12, the forward end of the spring 13 is disposed under the end portion of the lip 3, which may be recessed as shown at 15, therefor.
The rear end portion of the said shank L is formed as desired, integral with or securely attached to, various forms of attaching members usual to snap hooks, as inclicated at 16 and 17 in Figs. 1 and 6.
In Fig. 5 an embodiment of my device is shown as a double snap, utilizing two spring tongues secured by a single clamp. It will be noted as shown at 18 that one of the springs is inverted, the end li being turned down and disposed within a groove provided therefor in said shank 4.
The case with which the spring tongues of my device may be assembled with ordisassembled from ,thehooks will be obvious.
Obviously, the invention is susceptible of embodimentin forms other than that which is illustrated in the accompanying drawings and described herein, and applicable for uses and purposes other than as detailed, and I therefore consider as my own all such modifications and adaptations and other uses of the form of the device other than as herein described as fairly fall within the scope of my invention.
