7 Claims.

Vapertures in the impaling posts.

10 'Ihe invention comprises thejnovel structure and combination of parts hereinafter' described and more particularly pointed out and dened in the appended claims.

1 In the accompanying drawing which illustrates l5 a preferred form of this invention and in which similar 'reference numerals refer to'similarleatures in the different views:

Figure 1 is a fragmentary end elevational view of a record binder with one cover thrown back- 20 wardly and involving this invention.

Figure 2 is a fragmentary and enlarged sectional view taken through the pintle slide casing substantially upon the line II-II of Figure 1,

looking in the direction of the arrow.

25 Figure 3 is an enlarged sectional view taken through the rear endof the casing for the pintle slide showing the latter in elevation.

Figure 4 is an enlarged fragmentary' sectional view taken upon the linevIV-IV of Figure 2.

:i In connection with this invention, there is illustrated a record binder consisting of a cover member structure comprising aback member 1 to which pintle slide casings 2 are attached. The usual cover members 3 are hinged to the `back as 25 vis well'known in the art. Each of the casingsv 2 hasl suitable notches 4 in its forward edge for receiving theends of impaling posts -5 which, are provided withpsuitable apertures 6 for receiving the pintles 7 on the pintle slides 8. l'I'he 0 pintle Yslides 8 project beyond one end of the casing where they are provided with a rightangle finger portion 9.

In the present 'instance,lthe binder is shown with a casing and a pintle slide upon each side 5 thereof. It will, however, be understood that a single pintle slide may be used if desired. As the casings`and pintle slides aresubstantially duplicate except that one is right-hand and the other is left-hand, only one of them need be 50 described.

In referring to Figure 2, it will be noted that a spring yoke 10 is mounted within the casing and is provided with oppositely extending arms 10a. ,One arm 10a terminates in curved shoulder 55 11 which is located in a recess 8a in the pintle (Cl. 12S-24) slide 8 and is adapted for engaging either the shoulder 12 or the shoulder 13 in the ends of the notch or recess 8a as will later more fully appear. The other arm 10a of the spring yoke carries a rearwardly extending portion or arm 14 which 60 is located in a vrecess 15 cut in the edge of the pintle slide 8. A coil spring 16 in abutting relation with the rear shoulder of the recess 15 surrounds the portion 14. The two arms 10a merge into an eyelet 17 which extends through the back e5 of the binder and is anchored by means of a strap 18 which is fastened by a rivet 19 extending into the back of the binder.

In referring to Figure 3, it will be noted that a pin 20 extends through the casing 2 and serves 70 as a stop for the pintle slide 8, the rear end of which is adapted to abut pin 20 when it is pushed inwardly to its full operative position. When the slide is in its full operative position, the shoulder l1 on the spring yoke will of course 75 be no longer located in the notch 8a but will be positioned against the edge of the slide 8 at a point a short distance rearwardly of the rear shoulder of the notch l5. However, when the pin ,20, which may be in the form of a screw, is requ moved, the slide 8 can be pushed rearwardly untilthe shoulder 11 on the spring yoke engages -in the long notch 15 and is adapted for engaging the rear shoulder of such notch 15 for permanent- `ly locking the slide 8 from any forward movement 85 with the result that the binder becomes permanently locked. This permanent lockingu feature of the binder is very desirable when the binder has been filled and it is desired to store the same away for safekeeping.` 9 In the operation oi'this binder, the pintle slide 8 may be pulled outwardly by grasping the ringer portionl 9 until the shoulder 11 on the lock spring yoke 10 engages the rear shoulder of the notch 8a.

In this position of the slide, the pintles 7 will have 95 become entirely disengaged from the impaling posts 5 with the result that the cover and back portions of the binder can be swung into the position shown in Figure 1. However, as soon as the pintle slide is released, the spring 16 acting against 100 the shoulder 15a of the slide will force the same rearwardly until the shoulder 11 on the lock spring yoke 10 will engage the shoulder 12 of the notch 8a. In this position of the slide, the pintles '7 will bridge a portion of the notches 4 as shown in Figure 2. The pintles '7 are inclined at the forward edges as indicated at 7a with the result that they may be automatically thrust forwardly when brought into engagement with the impaling post 5. With the pintle slide in the position shown in 11 l pintles will snap the same forwardly in order to pass the impaling posts, and as soon as the pintles '1 come into registry with the apertures spring 16 will automatically draw the pintle slide` rearwardly and engage the pintles with the aper- 10 tures in the post. This automatic engagement of the pintle 7 with the post, 5 will of course be only partial but by manually pushing inwardly on the pintle slide 8, the pintles '1 may be brought into full engageme t with the impaling posts 5.

It will beappreciated that the spring lwhen put under compression by the forward movement of the pintle slide will act automatically to push the pintle slide inwardly a predetermined extent when released by the operator. This predetermined extent to which the spring 16 may autointle slide is equal to the matically operate the extent oi the notch 8a. slide 8 maybe withdrawn until the shoulder 11 strikes the shoulder 13 and when the pintle slide is released, the spring 16 will automatically-push the pintle slide inwardly a distance equal to the length of the notch 8a. 'I'his distance will partially project the pintles 'la across the notches 4, whereby such pintles may gaged with the impaling posts without the necessity or any hunting action.

I am aware that many changes may be made, and numerous details oi construction may be varied through a wide range without departing 3i from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the appended claimsv I claim as my invention:
