This invention relates to mechanism for supplying fastenings, and more particularly to mechanism having one or more raceways from which fastenings are delivered separately as required for use. The invention is herein illustrated as applied to a multiple raceway mechanism of a type commonly used for supplying tacks to the tack-driving instrumentalities of pulling-ever or lasting machines, features of whichare disclosed,

for example, in United States Letters Patent No. 1,002,422, granted on September 5, 1911 upon an application of It. F. McFeely. It is to be understood, however, that in its'inore general aspects the invention is not limited in utility to mechanism of that particular type. r

Mechanism of the type illustrated in the above-mentioned Letters Patent'includes aseparator movable to separate and deliver tacks from the lower ends of the inclined raceways, and an end block located at the lower ends of the raceways and provided with ooves so receive the separated tacks and C3 deliver them into the tubes that lead to the driving instinmentalities. Mounted on the end block are plates which overlapthe separator and the lower ends of the several raceways and are so formed and arranged as to provide supporting surfaces for the heads of the tacks at the lower end portions of the raceways in the same plane as the tack-sup porting surfaces of the remainder of the race ways, There is also a cover which overlies the lower end portions of the raceways and portions of the above-mentioned plates and the separator, the cover being mounted for upward swinging movement to expose the lower-ends or the raceways and to facilitate access to the separator.

In the use of mechanism of the abovementioned character it sometimes happens that movement of the separator is obstructed because of displacement of one or more tacks from normal position, the presence of an abnormally shaped tack, or for some other reason, and in that case it is usually necessary to gain access to the lower ends of the raceways and sometimes also to remove the. separator. To aft-0rd access-to the lower ends o n, u

of the raceways, and also to permit removal of the separator if that is necessary, the end block is accordingly so mounted that it may I be readily displaced or removed from operative position. If the separator is then removed, however, the tacks will slide out of the raceways unless there is means to prevent them from doing'so. If they are thus permitted to escape from the raceways, some of them may fall among the operating parts of the machine, into the tubes that lead to the drivers, or upon the floor and thus cause trouble and annoyance, and this involves also more or less wasteof tacks. To avoid such consequences in the use of mechanism of this general character, the present invention provides novelmeans for controllingthe fastenings in a raceway or raceways in such manner as to prevent their escape or delivery under abnormal conditions as, for example,

when the separator is removed. Conveniently, and in accordance with one of the features of the invention, there 1s provlded means controlled by the raceway cover for preventing delivery of fastenings whenever the cover is displaced from its normal position. Since the operator will almost invariably lift the cover if there is any interference with the movement of the separator, there isthus'afforded a substantial safeguard against escape or fastenings from the raceways the separator isremoved- In order, however, to insure such control of the fastenings, the cover in the construction shown is provided with a member which projects in front of the end block when the eoveris in its normal position and thus prevents removal of the ing of the cover.

' In a further important aspect the invention provides novel means for retracting the fastenings from the lower end portion of a race way or raceways, as well as for preventing their escape, under abnormal conditions. Such means is particularly advantageous in an organization of the type illustrated, in which the removableend block, as above eX- plained, carries means which provides sup porting surfaces for the heads of tacks at the lower end portions of the raceways, since the movement of the tacks away from the lower ends of the raceways facilitates the removal of such means and its subsequent replacement in operative position. For the purpose in view, in the construction shown the member hereinabove described for preventing delivery of fastenings from the raceways is somountcd and controlled as to have a movement lengthwise of the raceways to retract the rows of fastenings in addition to its movement downwardly toward the raceways, both these movements resulting from the lifting of thecover. More particularly, as herein illustrated this member is pivotally mounted for movement toward and from the raceways on a slide which is movable lengthwise of the raceways, and the lifting of the cover results in swinging the member downwardly into operative relation to the raceways and also in movement of the slide to cause the member to retract the rows of fastenings.

The difierent features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings, 7

Fig. 3 is a view similar to Fig. 2, illustrating the positionsof the parts when the raceway cover is lifted and the tacks are retractee from the lower ends of the raceways; and

Fig. t shows detached. a portion of the mechanism for preventing delivery of tacks from the racewa'ys and for holding them in retracted positions.

Since the generalcharacteristics of mechanismof the type illustrated are well known and are described in various prior Letters Patent including those hereinbefore mentioned, a brief reference thereto is all that is necessary for an understanding of the present invention. A rotary tack hopper 10 acts by intermittent movement to supply tacks t to a plurality of inclined raceway s 12 com prising members spaced apartto provide grooves or slots in which the tacks arrange themselves in rows supported by their heads. Mounted to reciprocate across the lower ends of the raceways is a tack separator 14 which separates the lowermost-tacks from the raceways delivers them into tubes 16 which lead to the tack-driving instrumentalities, these tubes being mounted in a raceway support 18. The separator 14 is detachably secured at its ends by screws 20 to a slide 22 by which it is operated. Mounted in front of the lower ends of the raceways is an end block 2% which serves, in part, as a guide for the separator 1d and is provided with grooves 26 to receive the tacks delivered by the separator and to direct them into the tubes 16. Secured to the end block 24 are plates 28 which ov rlap the separator 14 and the lower ends of the raceways l2, portions of these plates being reduced in thickness and provided with slots in line with the raceway slots, as indicated at 30 (Figs. 2 and 3), to receive the tacks and provide supporting surfaces for the tack heads at the lower end portions of the raceways near the separator. The lower end portions of the raceways are recessed to receive these plates, so that the surfaces of the plates that support the heads of the tacks are in the same plane as the tack-supporting surfaces of the re mainder of the raceways.

Mounted in a fixed position over the upper end portions of the raceways 12 is a cover plate 82, and pivoted at 83 on upraised portions 3st of this cover plate are arms tnat prog'ect from a cover 36 which in its normal position (Figs. 1 and 2) is over the lower end portions of the raceways, and also partially overlaps the plates 28 over the separator 14, the cover 3-3 carrying screws 39 the ends of wnicn normally rest on the plates 28 to as sist in supporting it. This cover may be swung upwardly about the pivot 83 to eX- pose'the lower end portions of the raceways.

In the use of mechanism of this character it sometimes nap; ens that because of the presence of an abnormally shaped tack, dis placement of one or more of the tacks from normal position, or for some other reason movement of the separator 14; is obstructed. In that event it is usually necessary to gain access to the lower ends of the racewavs and sometimes also to remove the separator in order to get rid of the obstruction. Accordin ly, as disclosed in the Letters Patent mentioned, the end block 24, with its plates 28 that overlap the separator, is so mounted that it may be readily removed, thus affording access below the separator to the lower ends of the raceways and also facilitating removal of the separator if that is necessary. To permit such removal the end block is provided at each of its opposite ends with a spring-controlled plunger 38 (Fig. l) which projects normally into hole 40 in the raceway support 18. Members l2 which are mounted on pins 43 connected to the plungers 38 through slots in the block 24 provide means i w tiilt whereby the plungers may be readily with drawn from the holes to release the block, and the block may then be removed by sliding it forwardly away: from the ends of the ETeiCGWEIFS in a direction parallel to the incline of the raceways The separator 14 is made up of a number of separate parts, as cr'ofore, secured together. byscrews and indicated at 44 (Figs; 2 and 3) which 45 extend in order e normally movable in recess agthwisc of the end block vent these screws and nuts from ini 'ng with the removal of the end block, the latter is provided with recesses indicated by dotted lines at 46 in Figs. 2 and 3, which are so arranged as to be opposite the screws and nuts 44 when the eparator is in one position so that unobstructed removal of the end block is permitted.

It will be evident that if the separator 14 is removed the tacks will escape from the raceways unless means is provided to prevent them from doing so. The present invention provides novel means for preventing such delivery or escape of tacks, t iis means being constructed also to slide the rows of tacks upwardly portions of the raceways, and especially from the recessed portions of the plates 28 which, as hereinbefore described, support the heads of the tacks at the lower ends of the raceways, thus facilitating removal of these p tore J 1 rates with the end block 24 and their subsequent re placement. For the purpose in view there is positioned under the'cover 36 abar 47 which extends over the se'ies of raceways and is provided with a plurality of projections or fingers 48, one for each'raceway, which are arranged to enter the grooves of the racer ays in front of the lowermost tacks positioned therein. the bar 4'? is supported on arms 49 which are pivotally mounted at, 50 on a slide 52 providedon its opposite sides with tongues 54 which are mounted in grooves or slideways 56 formed in the upraised por-' tions 34 of the fixed cover plate 32, these slideways extending in parallel relation to th raceways 12. The arms 49 at their rear ends are joined by a yoke-shaped member 60, and between this member and the slide 52 is a spring 62 which acts normally to hold the bar 47 upraised within an arched recess 64 3) in the cover 36, the arms 49 being positioned in recesses 66' in the cover.

hen the parts are in normal positions the projections 48 on the bar 47 are thus raised above the raceways and above the plates 28, as illustrated in Fig. 2.

in. order to stop delivery of'tacks from the raceways andto retract the rows of tacks from thelower ends of the raceways as here- 7 inbefore described, the arms 49 are operated by the lifting of the cover 36 to swing the bar 47 downwardly, and by the same movement of the cover the slide 52 is operated away from the lower end to carry'the bar along the raceways, so that theprojections 48 enter the grooves of the raceways and force the rows of tacks away For from the lower ends of the raceways.

imparting the downward swinging move-. ment to the arms 49 the arms 35 of the cover,

36 are provided on their rear ends with cam faces 68 (Fig. 3) which act to depress the arms 49 when the cover is lifted, and for moving the slide 52 along the raceways by the same movement of the cover the latter is connected to the slide by a link 70 pivoted at i .raceways through movement imparted to the slide 52, so that the projections 48 of the bar 47 are carried downwardly into the grooves of the raceways in front of the lowermost tacks through the slots 30 in the plates 28, and that by continued upward swinging movement of the cover the projections 48 are then moved along the raceways to retr ct the rows of tacks from the tack-supporting portions of the plates 28. Preferably, the projections 48 are so formed, as illustrated, as to extend rearwardlyimder the heads of the lowermost tacks into engagement with the shanks of the tacks, for better control of the tacks as they are moved upwardly along the raceways. Toassist in maintaining the cov or 36 in its lifted position, there are mounted in the'upraised portions 34 of the plate 32 spring-controlled plungers which are arranged to engage fiat faces '78 on the rear end portions of the arms 35 of the cover. These plungers also assist in maintaining the cover in its normal downturned position by engagement with other flat faces provided on the ends of the arms 3 the operator will normally lift the cover if there any interference with the movement of the separator, itwill be evident that by controlling through movement of the cover the means for preventing delivery of tacks from the raceways and for retracting them from the lower ends of the raceways, substantial ertaintyis afforded that this means will. be in operative position at any time when the s arator is removed. There is, however, fur J61 providedmeans I for positively insuring that L118 tacks will be controlled in the manner lab pvwnich is controlled end block 2 that is, the path which the end blocl-r must take if it is removed from e invention ther is thus provided means by movement of the retor preventing delivery taming member 82 r the raceways if the end of tastedigs from block is displaced.
