s head including atop member ZSand abottom 44, 46 which provide therebetween a passage 48 in communication with the magazine 42. It is to be noted that the zig-zagged strip I4 may be inserted in the magazine 42 through a suitable door 56 hinged as at 52 to the aforementioned wall 44, the door 58 being openable as indicated at 54 and any suitable type of a removable cover 56 being provided on the top member 28 so that access to the interior of the head 26 may be had for the purpose of opening the door 56 and installing the strip I4 in the magazine 42. It is to be noted that the door 52 and the floor of the magazine 42 are provided with inwardly projecting detents 58, 60 respectively, which detents are intended to engage and separate, so to speak, the individual blanks I2 in the strip I4, prior to the admission of the strip i4 into the passage 48 in a flat form.

The reinforcement strip I4 is propelled through the passage 48 by an automatic feed mechanism designated generally by the reference character 62, which will be hereinafter more fully described. After leaving the passage 48, the reinforcement strip I4 is subjected to three separate and distinct operations, namely, preforming, separating and installing, this work being effected at three different locations, namely, what may be referred to as the preforming station 64, the separating staiton 66, and the installing station 68. As will be hereinafter more fully apparent, these various stations involve the provision of equipment or facihties on the platform 24 of the base 28, and on the bottom member 36 as well as on the top member 28 of the head 25.

The preforming station will rst be described, this involving the provision of a support block 18 best shown in Figure '1, which is secured to the top member 28 of the head 26 by suitable screws 12 and is equipped at the under side thereof with an acorn-shaped preforming punch 14. This punch is preferably of a hexagonal cross sectional configuration and is formed integrally with a base 16 and with a screw threaded shank 18, whereby the entire preforming punch is secured to the support block 16 by a nut 86, as will be clearly understood. Upon depression of the pad 4|), that is, upon depression of the applicator to a position shown in Figure 2, the preforming punch 14 is forced through aligned, hexagon shaped openings 82, 84 in the aforementioned walls 44, 4o respectively, registrabie opening 66 provided in the platform 24 of the base 28. The openings 82, 64 and 86 actually assume the form of a die for the punch 14, so that when one of the reinforcement blanks I2 is in position in the preforming station 64,

upon depression of the applicator, the precut center portion of the blank will be struck out and separated into several substantially triangular sectors and these sectors will be bentI downwardly as indicated at 88 in Figures 2 and 5. It should, of course, be understood that the bottom wall 45 and the passage 48 terminate at the preforming station 84, so that after the sectors 88 are formed, the blank is free to travel to the separating and installing stations 66, |58 respectively. That is to say, the aforementioned opening or aperture 64 in the wall 46 is not closed, but rather, assumes the form of an open notch or recess, from which the preformed blank may be slid laterally without obstruction.

The installing station 68 will be next described, this assuming the form of an installing punch 90 which, like the preforming punch 14, is equipped with a base 92 and with a screwand through a similar,

4 threaded shank 94, whereby the punch 90 is scured to the platform 24 by means of a nut 96.

The installing punch 98 is receivable in a hexagonal aperture 98 formed in the wall 44 of the bottom member 3U and it is to be noted that a deflector |00 is installed on the punch 98, substantially as shown. When a preformed blank is in the installing station 68 and a loose-leaf |02 to which the reinforcement is to be applied is located on the punch as shown in Figure 3, upon depression of the head 26 the preformed reinforcement will be brought in engagement with the punch and the deflector |66 will permit the sectors 88 of the reinforcement to pass through the opening in the leaf |02 after which the reinforcement sectors 88 will be bent or doubled under the leaf |82 so that the reinforcement will be f'lrmly and securely retained in position on the leaf.

Means are provided for separating the applied reinforcements from the main body of the strip I4, this operation being effected at the separating station 66 and involving the provision of a separating blade |84 which is secured by a screw |66 to the aforementioned support block 16. Upon depression of the head 26, the blade |04 is projected through a slot |88 formed in the aforementioned wall 44, whereby the installed reinforcement is automatically separated from the strip i4 when the head 26 is depressed.

The aforementioned feed mechanism 62 consists of a pair of spaced substantially parallel wire arms IIl which are connected together adjacent one end thereof by means of a suitable holding plate I |2 and are pivotally attached as at ||4 to a rod 32 provided transversely in the support 22. The free end portions of the arms II provide what may be referred to as a pair of arcuate feeding ngers I I6 which extend through pairs of aligned slots IIS formed in the walls 44, 46, substantially as shown. In this manner, the fingers ||6 extend through the reinforcement passage 48, and it is to be noted that a suitable spring |20 is provided on the pivot rod 32, this spring engaging the plate ||2 and urging the fingers ||6 of the arms |||l through the slots |I8. Suitable pads |22 are secured to the fingers I|6, these pads being slidable on the upper surface of the wall 44 and thus preventing the spring |26 from urging the fingers ||6 through the slots i i8 to excess.

The configuration of the slots I I8 is best shown in the accompanying Figures 4 and 6, wherein it will be noted that the slots terminate at one end in outwardly arcuated portions |24, while the remaining ends thereof terminate in outwardly angulated portions |26, the fingers ||6 being disposed in the slot portions |24 when the head 26 is depressed as shown in Figure 2. However, inasmuch as the pivot rods 32, 34 are spaced one from the other, raising of the head 26 in the direction of the arrow |21 will cause the fingers Ilia` to travel inwardly and forwardly in the slots ||8 as indicated at |23 in Figure 4, until the head 26 is fully elevated as shown in Figure 3, at which point the ngers ||6 will spring outwardly into the slot portions |26, as indicated at |38 in Figure 4. It should be explained at this point that the arms l I8 are resilient so as to normally urge the ngers I|6 outwardly into the slot portions |24, |26, the travel of the lingers through the intermediate portions of the slots I|8 being effected against the resiliency of the arms III).

Matters are so arranged that when the head 26 is moved from an elevated to a depressed position, the fingers H6 by virtue of their arcuate configuration, simply slide upwardly over the edges of the slot portions |26 and after leaving the latter are drawn rearwardly as indicated at |32 in Figure 4, until they drop into the slot portions |24 when the head 26 is fully depressed.

Referring again -to the movement of the fingers H6 in the direction of the arrows |28 when the head 26 is being elevated, the fingers while moving in this direction, of course, extend through the passage 48 and are brought in engagement with the recesses I8 between two of the reinforcement blanks, and by virtue of this engagement, the fingers ||6 propel the reinforcement strip through the passage 48 toward the preforming station 64, and at the same time, propel the preformed blank from the station 64 to the installing station 68 until the fingers are disengaged from the recess-es |8 and are sprung laterally into the slot portions |26. On the other hand, when the head 26 is depressed, the fingers ||6 simply disengage themselves from th-e slot portions |26 and travel as indicated at |32 into the slot portions |24, after which the fingers engage themselves with the recesses (I8) between the next adjacent set of reinforcing blanks, as will be clearly apparent. As a result, when the head 26 is depressed, one of the reinforcement blanks will be preformed in the preforming station 64 While another reinforcement blank, already preformed, is installed on the sheet |02 in the station 66 and is simultaneously separated from the strip I4 by Ithe blade |04 in the station 66, as will be clearly understood. Thereupon,

when the head 26 is raised to its elevated position, the feed mechanism 62 advances the strip i4 so that the preformed blank is brought into position in the installing station 68 and another blank is brought into position for preforming in the station 64, in readiness for the next depression or actuation of the applicator.

In conclusion, it may be explained that the -top member 28 is provided under the pad 40 with an inturned flange |34, whil-e the bottom member 30 is formed with an outturned, coacting flange |36, these anges being engageable one with the other so as to prevent the members 28, 3|) from becoming separated to an excess, as will be clearly understood.

It is believed that the advantages in use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is deemed 11nnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
