BELT-LACING' DEVICE.

Application filed May 215,

This invention relates to improvements in belt lacing device.

One object'oi' my invention is to provide a simple, eiiicient andrelatively inexpensive device for applying lacings to belts of any width.

Another' robject of my invention is to provide a hand-operated device of the type indicated in the preceding` paragraph adapted for belts or aprons up to tenk feet or even more inwidth, such as are commonly used in laundry ironers and the like.

More specifically, an object of my inventiony is to provide a belt lacing device adapted for different width belts or aprons, wherein the holder 'for the belt lacing and the anvil as? sociated therewithare made in unit lengths adapted to be so assembled as to provide for any desired width of belt or apron and'with which is associated a relatively small, travcling striker block, `adapted to be struck by a hammer or other suitable tool, whereby the desired length of belt lacing corresponding to the full width of' the belt maybe 25. clinched by shifting the striker block from point to point along the device and striking the same with a hammer, all in a quick, expeditious manner.

' Other objects of the invention will more clearly and fully appear-from the description and claims hereinafter `following.

In the drawing forming a part of this specification, Figure 1 is la top. plan View of a belt lacing device showing Vmyiimprovekments embodied therein. :In'thisy view, the device is broken off at one end and` also broken away intermediate its ends in order to illustrate the device on a suitablescale. Figure 2 is a vertical, transverse,.sectional view corresponding to the section line 2 9, of Figure 1 and illustrating the position or the striker block just as ity engages the belt lacing. In this view, portions of the base are broken away to accommodate the figure on the sheet. Figure 3 is avew similar to Figure 2, but illustrating'gthe position of the striker yblock whenthe' belt lacing is partially clinched to thebelt'or apron. Figure 4 is a front elevational vview of the striker block detached. Figure 5 is Aa top plan view of a yform oit'beltlacingv usable with my` improved device. lFigure 6 is a plan view of a portion of abelt'o'rapron theother parts. .Said base A will be -made 1927. semi No. V194,019.

of suitable length corresponding tothe maxvimum width ol" belt or apron forfwhich the device is to be used, this length: 'frequently beingy as much-as ten feetland,.of course, may be more. f 70 Secured to the upper side of the base A, 'as by the bolts '10, is an elongated support B, which will also be made of a length cor'- responding approximatelyk to the length of the base A. Said support kB preferably comprises a barlike element, which is suitably machined so as to provide a Hat bottom y 1 1; a vertical inner face 12 v'andan outer vertical face 18. On thetop, the bar support B is provided with an elongated guideway 14 near the inner edge thereof anda relatively wide elongated recess 15 rec tangular in cross-section, for the purposes about tor be describedl Between the guideway 14 and the` recess 15, the support Bis thus 'left with an upstanding wide rib se'ction 16, to 'whichthe ylacingholder isi-se! cured.. i .i i The belt lacing holder, indicated generally by thereference characterC, consists of a plurality of unit sections 17-17, at their. adjacent ends abutted as indicatedV at 18 in Figure 1, said unit sections being secured to the rib. 16 by. a series .of rmachine screws 19-19. Each unit l17 will preferably be made of about onek foot length, thus adapting itfor economical manufacture and will be comprised preferably of brass. Inthis manner, it is evident that a holder of any den sired length may be built up, cor.responding 100 to the maximum width of the beltor apron to be .operated upon andv further,` should any Vpart of the holder become'injured, it can readily be replaced by another unit length of like construction.'Eachv unit section 17'of the lacing holder has the front face thereof beveled as indicated at and the front edge slotted or milled so as to provide a plurality of substantially triangular recesses 21 separated by triangular partitions 22. In this manner, the prongs 23-23 of the belt lacing are adapted to be received within the respective spaces 21 and the lacing held by means of a holding pin 121i, which is extended lengthwise of the lacing holder' and passed through suitable alined holes in the partitions 22. As will be understood by those skilled in the art, thc lacing may be supplied in suitable lengths and one well known form of such lacing is indicated in the drawing. y y

In the manufacture of the holder unit sections and in assembling the same on the sup- ,port B, itis essential that the units be Aaccurately aligned and the milling of the slot-s or recesses to receive the lacing be uni form and to this end the unit sections 17 are each provided with a shallow groove 24 on the underface thereof. Said groove 24 is used as a gauge for the milling of the slotted edge of the holder and also the grooves 24 of the assembled unit 17 receive a rod 25 extended lengthwise` thereofand which accurately .fits the grooves 24 so that, when the units are thus assembled with the rod 25 in place, they are accurately aligned and may then be secured in place by tightening the screws 19. With this arrangement, it is evident that I ain not dependent upon the accuracy oflocation of the tapped holes for securing screws 19 which may vary slightlyv under manufacturing conditions.

s will be evident from an inspection of Figures 2 and, the holder is of a width corresponding substantially to the horizontal width of the rib 16, thus presenting the most advanced part of the holder to a point in line with the front vertical edge of the rib 16. Disposed in the elongated recess 15 is the anvil of my improved device, said anvil being indicated generally by the reference character D. The anvil is comprised preferably of a plurality of unit lengths 26-26 of vcase-hardened or otherwise suit ably hardened steel adapted to withstand the blows incident to the clinching ofthe belt lacing. The anvil sections 26 .are of a depth slightly greater than the depth of the recess 15`and the upper faces of the anvil sections 26 are beveled downwardly and inwardly along their inner edges as indicated at 27, the innermost edges of the beveled port-ions terminating substantially Vflush with the lower surface of the holder C, forl the purpose hereinafter described. By making the anvil in lunit sections corresponding preferably in length to the unit sections of theholder, it will be seen that I can make the devioeof any desired lengt-h andalso am enabled to effect replacements at minimum cost.

or shear the fabric.

Cooperable with the holder andL anvil described in the preceding, is a striker block indicated'generally by the reference chan acter E. Said striker block E is preferably made of a length slightly less than half of the length of the `unit sections of the lacing holder and is provided .on the top with a rounded striking surface 28, against which ythe hammer impinges when clinching the acter F. The pin 31 is retained in position y byany suitable means such as the cotters 3333- As will be evident from an inspeetion of the drawing, the arms 29 str'addle the carrier F and the blockE is thus adapted to swing through an arc of approximately 180 with reference to the carrier F. Therblock E is provided along its front edge with a depending suitably hardened section 34, the bottom face 35 of which affords astriking face so located as to engage the upstaiiding vprongsrof the beltI lacing as indicated in Figure 2. The innermost portion of vthe striking face 35 is beveled or slightly rounded in a direction opposite to the beveled portion 27 ofthe anvil soy that, when the striker block Eis in its lowermost position and at which time the lacing is clinched to the belt or apron 36, the two beveled faces converge in a direction away from thel lacing holder. The arrangement of the striking beveled faces of the striker block and anvil is an important feature particularly when the device is used in connection with comparatively thin belts or aprons, such as canvas, and correspondingly smallsized belt lacings. It will also be noted, by i'eference to Figure 7, that the portions of the striking faces of the anvil and striker lblock which are remote from the holder, will be parallel or.` approximately parallel at the final clincliing opera-tion. With Vthis arrangement of oppositely beveled striking faces and parallel faces, the prongs of the belt lacing may be properly clinched in the belt or doubled over end of the apron and the outer faces ofthe prongs brought flush with the outer faces of the belt or apron without danger of the prongs of the lacing being forced so closely together as to tear Further, the parallel portion of the faces ,will engage the apron or belt outwardly of the lacing proper and hence the downward movementA of the striking block willV thus be limited'by the belt or of the lacingzwithout. danger of deforming the usual hingepin receiving portion of ,the lacing or danger of tearing or injuring the fabric or apron, is positively assured.

apron.v In thismanner, proper application in a longitudinal rabbct 40 provided on the bottom of the support or bar B. As'will be understood, the plate 89 is secured to the vcarrier F by suitablescrews 4l and the carrier is slipped endwise' onto the support B and may be adjusted tovany point thereon.

In the operation of my device, a suitable length of belt lacing is inserted in the holder and secured therein by the pin 34 in the manner indicated kbest in Figure 2. The edge of the belt or apron is then presented to the holder between the two sets of prongs of the lacing as indicated in the same view and then the striking block E is hammered down preferably beginning at one s-ideof the belt and woi'king gradually' along the entire width ofthe belt until the entire length of lacing is applied. The pin Q4 is thenl removed and the 'apron' or belt with tlieflacing 'attach'edfalso removed. l

Iny the drawing, I- have illustrated one specific form of belt lacing and tol which the termlacing is technically correctly applied. 'Howeven as will be obviousvto those skilled inltheart, other forms of belt lacings or fasteners such as a series of individual hooks or staples may be used with my improved device and I employ the terms lacing or belt lacing in the appended claims, broadly, to include any type of belt lacing or fastening.

V,From the preceding description taken in connection with the drawing, it will befevident that -my improvements may be ymanufactured at comparatively small-cost and the device'made for any suitable width of `belt or apron. The lacing maybe applied readilyand without the aid of anyspecial tools, the only tool required Vbeing a hammer or the equivalent. 1 1 Although I have herein shown and describedv the preferred .manner lof carrying' out my invention, I am aware that various changes and modifications could be made without departing from the spirit of the invention, and all such changes and modifications are contemplated asv come within the scope of the claims appended hereto.
