DEVICE F'PR APPLYING- ANI) REMOVING COTTER-PINS.

Application filed. October 12, 1907. Serial No. 397,046.-

To all whom it mag concern:

Be it known that I, WILLIAM C. J AEGLE, a

' citizen of the United States of America, re-

siding in the borough of Manhattan, in the city, cohnty, and State of New York, have invented a Device for A plying and Removmg- Cotter-Pins, of whic 1 the following is a I specification.

ploy ordinary tools for that purpose.

The objects of my invention are to produce a device, by means of which cotter pins may be introduced in place without (lest-r0 mg their naturally open set; another 0 ject is to produce a device by means of which the projecting ends of the cotter in when introduced in placemay be opener so as to prevent accidental removal of the cotter pin; another object is to produce a device y means of whi h the open ends of the cotter pin may be flexed so that the pin can be removed; andanother object is to produce a device by means of which the (otter pin may be removed from its seat.

Further objects will appear from an examination of the following specification and accom singing drawings. 4

In t e rawings, Figure 1 is a side elevation of a portion of one embodiment of my invention with the jaws in the separated position. Fig. 2 is a detail view of the same taken at right angles to Fig. 1. Fig. 3 is a 'detail view of the lower end of the same with the aws closed. Fig. 4 is an elevation of the extracting device. Fig. 5 is an elevation of a modified embodiment of my invention. Fig. 6 is a detail view taken at right angles thereto. Fig. 7 is a bottom plan view thereof. Fig. 8 is an elevation of a further modi fication. Fig. 9 is a detail view showing the application of the device for straightening the ends of the cotter pin; and Fig. 10 is a bottom view of the device shown in Fig. 1 showing the cotter pin lying at right angles to that illustrated in Fig. 2.

In all of the views like parts are designated by the same reference characters.

Figs. 1 and 4 representan embodiment of the invention in which the introducing and extracting mechanism are disconnected. Figs. 5 and 8 show structures in which the applying and extracting mechanism. are con- Patented Aug. 4, leosi In the structure shown in l best formed of steel or other elastic material,

and the arms are best formed integral therewith. The free extremities of the arms carry jaws 4-5. The opposing faces of the jaws are set back at an angle, as shown, so that when the two are brought to enga ement by flexing the arms 3 they will grip t c cotter pin 6 at a point adjacent to the lower faces of the jaws and will bite into the pin and prevent slipping of the pin in the jaws. The arms 3 are normally opened by their elasticity, and are closed by a device sliding upon the body 1 and arms, such device being applicable at a point adjacent to the head 2. T is device, as shown in Fig. 1, comprises a rod 7 having extremities bent at an angle with holes through which the body and arms pass, and which slides freely upon such body and arms. The opening of the rod which surrounds the arms is of such a size that when the rod is moved toward the a ws it will inclose and compress the arms )gether, engagirsuch jaws. The ower face of tie jaw 5 18 shown as provided with a recess 8 ada ted to engage with the head of the cotter nn 6, to push it home when it has been part y inserted in its seat.

The device for closing the jaws 4 and 5 may be modified, one form being shown in Fig. 5. In this structure, instead of the rod 7, a sleeve 9 surrounding the body and arms is employed. The sleeve is provided with a flange 10, being a means for sliding the sleeve, and for another purpose, which will be described. The lower end of the sleeve fits sufficiently close around the arms 33 the jaws and grip ingth cotter in betwee. I

so that when the sleeve is moved to the position shown in Fig. 5 it will force the two arms together, causing the close engagementof the jaws 4 and 5. In this modification the recess at the bottom of the jaws is formed in both of the jaws instead of in one, the jaws in the modification illustrated in Figs. 5, 6 and 7 being both of the same size. As shown in Fig. 7 the abuttingfaces of the jaws are provided with notches 11, so that when the aws engage with the cotter pin the surface engaged with will be greater than if such notches-were not used. In Fig. 8 is 4 by pressure exerted upon one side of the arm supporting the jaw 5, the arm supportmg the aw 4 being sufficiently rigid to form 'a support against which the other jaw engages. Engagement of the two jaws is made by means of a lever 12, which is pivoted to the body and provided with a handle 13 ad- 4 opened by the reversed movement of the jacent to that end of the body opposite to the-jaws. The other end of the lever 12 is provided with a ring 14, which surrounds the arms-'3.3; engagement of the base of the ring with the lighter of the two arms, will, when the lever is caused to pivot, close the two jaws with any degree of prcssure-de- Sl'r6(l.; The lever 12 may be supported in disengaged position by means of a spring 15,- if such is desired.

Y The device for removing the cotter pin in the form of a hook 16. This hook may be separate from the body 1, as shown in Figs. 1 and 4, or connected thereto, as shown in Figs. 5 and 8.

In the first embodiment of my invention the device is shown as made in two parts, one part carr 'ng the jaws 4 and 5, and the other part the 00k 16. Inthe otherembodiments of my invention, the device is shown as made in one part, such part having the jaws 4 and 5 at one end and the hook 16 at the other.

The operation of the embodiment of my invention, described and illustrated, is as fol- .-.-.'-ws: To 3. ply the cotter pin it is first placed between t e jaws 4 and 5 and the latter closed upon it, as shown in Fig. 2.. The engagement of the jaws with the pin should be close to its free ends so that the limbs of the pin may be closed together readily against their normal tendency to remain set in open osition. The cotter pin isnow' introduced into its seat, which may be readily done as the two limbs of the pin are closed. when introduced in its seat, the jaws 4-5 are mechanism employed for closing them. The recess 8 on the aws is then caused to engage with the hes-.1 or the cotter pin and the latter is pushed home into its seat. if desired the cotter pin may be fur her secured by separating free extremities m the manner shown in Fig. 9, although this will not be necessary ordinarily, as the cotter pin may be introduced by my device without ireo Withdrawthe cotter pin the ook 16 is used. If the free ends of the limbs of the cotter pin are widely se arated, as shown in Fig. 9,

they may be *rougnt together by applying th jaws 4 and 5 to the free end of the limb,

as shoe-o. in Fig. 9, and swinging the device I so that longitudinal line is in line with the longitudinal center line of the cotter pin.

The'free extremities of the cotter pin may then be pinched together by closing the jaws 4 5 u on them with suflicient force to attam this end. In using the structure shown m Fig. 5, the flange 10 may beused as a means for pressing the cotter pin home tool. The gripping surfaces of the jaws 4 and 5 are set back at an angle, as already described, so that any resistance of the cotter pin to be seated results in a closer grip of the aws with 1t.

It is apparent that a device made in accordance with my invention may be used in situations where ot or tools cannot be employed. This adv [ntage is particularly striking in automobile work in which cotter pins are abundantly used and which are employed in most inaccess ble places. If the manipulation shown ii 9 be dispensed with, the cotter pin may be introduced and removed from a place somedist'ance from the.

seat of the in, and thro gh a space of relatively smal area. The devide, therefore, possesses great utility in suehsituations, as it makes possible the z.pplication and removal of cotter pins with the expenditure of a minimum of time, tern )er and atience.

In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the appa ratus which I now consider to re resent the.

(lOSlIGlZO best embodiment thereof, but have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other we *s.
