Specification of Letters Patent. A Patntdtay 17, 191i).

Application led october 29, 1909. Serial No. 525,251..

To all whomit may concern:

Be it known that I, TiroMAs G. PLANT, a

citizen of the United States, residing atA Boston, in the county of Suiolk and State of' Massachusetts, 'have invented an 1mshoe treatin machines. In the present em 4hodiment o the invention the luhricating devices are illustrated and described in connection with a machine for treating the heels of 'boots and shoes, although, as will be obvious, the invention is not necessarily re-V stricted thereto.

As well understoodby those skilled inthe art it is com-mon to form'o eni'ngs in the heels of boots and shoes for t e, iiisertionvof the fasteninr means which eitherhold the parts of the' eel together or unite the heel to the heel seat. It is ordinarily the practice,

also, tocompress the heel and while in this compressedcondition to prick'it. Obviously grr-ea: friction results by the passage of the awls throu h the heel, and the heat generated is liable to cause serious injury to the awls, as will be readily'un'derstood.

In the drawings :-Figure. 1 is a general side view of one form of 'heel' treating maf chine having the present inventionassociated therewith; Fig. 2 is a section on the line 2-'2 of Fig. et; Fig. 3 is a section on the line 4 is an enlarged detailv of the upper portion of the machine of FiO'. 1, with parts broken away to more clearbly disclose the elements beneath; and Fig. 5 is a section on the line 5-5 of Fig. 4.

While, as hereinbeforenoted, the invention is applicable to a large variety of machines wherein awlsor prickers are used for piercing leatherthepresent embodiment of the' invention Vv,indicates itsfassoci ation with back View of one si Y a heeling machine "ofnthegeneral' typeset" -orth in my prior ,applieationf No. 412,727,

may he had.

Having reference to Fig. 1 the inacl'iinev frame 1 rising fromt-he supporting base 2 may he of any desired construction to ac- 1908, to which reference commodate the working parts, and itV has mounted in .suitable bearings therein the shaft 3 having appro riate cams e which act lupon thel lower env s of rods 5 connected at their upper ends at 6 to the cross`head '7, in all of which respects the general characteristics of the machine shown in the drawings may correspond to the like parts ininy prior application referred to, or otherwise as desired.

Mounted insuitable bearings in the crossvofy head 7 is the turret shaft 8 carrying the usual awls or prickers 9 and nail driving devices (not shown).- Connected to the turret .shaft 8 isthe segment gear 1G' operatively joined to the actuating shaft 11-bysiiitable gearing, as set forth in iny said application,

and said shaft 11 is 'itself actuated through a -gear 12 and the sliding rack har 13 which may be actuated in any suitable manner, or as pointed out in said application. i

, The turret which carries the awls andvnail sov driving devices is preferably provided withl the guiding pins 14 and 15, said pins being' adapted to engage the perforation 4in a lunr 16 secured to the fixed cross frame 17 carried by the machine column, the construction being such that one of said pins 14 or 15 will V engage the said perforation and serve to guide either the awls or nail driving devices as the cross-head rises and falls.

As usual in this class of machines, the

cross-head carrying the turret is first moved downward toV cause the awls to penetrate the heel and then raised to permit the awls to be moved to one side by partial rotary movement of the turret, and the nail driving devices to be brought into coacting vrelation with the-fasteners to he driven, whereupon thecross-head is again caused to descend to drive' the fasteners. These features and characteristics of a heeling machine are well understood and'need no .further elucidation.

Secured to the machine frame-inposition to receive the awls 9 wheii'they' are in their inoperative position, asfindicated in Fig. 4, l:isiagcasing 18,.,Figs. 1, 2 and-3, said casingA 'ioo Y having an openvtop, andV its side next adjai the turret head bein also open' to periflitf the awls'to enter sid casing as' the tank 21, said tank being disposed below the cylinder 23, Figs. 1 and 3, in which fitsr a portion 32 adapted to be engaged by the Ipin 29 to receive the securing bolt 30, the-con verly adjust the tension of the spring 25 and indicated in Fig.

lwill be depressed by the casing 13 and conveniently attached to the machine frame by Suitable means, such as the screw bolts 22.

Rising from the lubricating tank 21 is a hollow plunger or piston 24, normally `held in its raised position by means of a spring 25 connected at oneend 26 to the interior of v`the piston or. plunger and at its other end 27 to a suitable lug secured to or projected from the cylinder 23. In order that the tension of the spring 25 maybe readily adjusted to suit the conditions of'use, the lug or pin 27 is preferably carried vby an adjustable bracket 28, Figs. 3 and 4, which is slotted at structionbeing such that upon loosening the securing bolt 30 which is tapped into the cylinder 23, the lug or pin 27 may be adjusted vertically in either direction to Apropcause it to normally 'hold the .plunger or piston 24 in raised position. Likewise Secured to the plunger or piston 24 is an `arm or lug 31, Figs. 3 and 4, having an upper 14 secured to the cross-head turret, w ien said pin and the .awls which are disposed arallel thereto are in their side position, as 4, and upon depression of the cross-head.

It will be noted that the cylinder 23 coinmunicates directly with the interior of the lubricating tank 21, and froui the construction described it will be noted that the spring 25 will act to hold the piston or' unger 24 in raised position, and as the crosshead descends this plunger-or piston v piu. 14, provided the awls are at the time being in inoperative or side position. It', however, thc awls and perforce their guide pin 1'4 are not in inoperative or side position as the cross-head descends, but are in active position to pierce or prick the shoe-heel, then the arm or lug 31 'and its connected piston or plungel' 24 will not betlepressed.

Rising from the lubricating tank 21 is an aspirator- 33 which is secured to the top of vthe tank by means ot a suitable nut and screw connection 34. Passing through the tube of the aspirator is the inner tube 35 which extends to near the bottoni of the tank, as indicated in Fig. 4.

Projecting from the end 36 of the aspiltop of the lubricating tank 21.

rator, Fig. 2, is a hood, preferably of conical form, leading into an opening 38 i in the wall of the casing 13, Figs. 2 and 3, l

currents through the aspirator, as indicated in Fig. 2.

In order that the oil' spray projected by the aspirator may be conied to proper action upon the awls 9, in the manner hereinbefore noted, the cross-head' 17 has secured thereto a casing 39, Fig. 3, disposed to receive the ends of the awls, when said awls are in their side or raised position, as indicated i'n Fig. 4. The general characteristics of the casing 39 are such that as the crosshead descends, said casing 39 will telescope into the casing 18, thus inclosing the awls by a substantially closed chamber for the act-ion of the lubricant. In order that the lubricant may pass into the awl chamber thus .created by the two casings 18 and 39, the casing 39 is provided with an opening 40, Fig. 2, which registers with the opening 38 aty-tlie end of the hood 37, when the casing 39 is in lowered position, as indicated in Fig. 3, the construction being such that the oil spray will be projected into the casing 39l into intimate contact with the awls as they and the casing 39 move downward under the action of the cross-head.

As hereinbeiore noted, the bottoni of the casing 18 is formed preferably inclined, as at 20, Fig. 3, and connected tothe lower portion of the casing, as at 41, Figs. 1, 3 and 5, is a drainpipe 42 through which surplus lubricant may pass. This drain pipe is preferably connected to the top of the lubrieating tank'21and provided with a suitable strainer to prevent dirt and other foreign substances getting into the tank. @ne convenientform of such strainer is indicated in Figs. 4 and 5, wherein it comprises a suitable casing 43 containing fibrous or other straining material '44 connected, as at 45, with the drain pipe 42. Connected to the strainer casing 43is a pipe 46 leading to the ln order that air may not escape into the pipe 46 and find its way into the casing 18 upon depression of the piston or plunger 24, the inlet-to the pipe 46 is preferably provided with a stop valve, one form of which is indicated in Fig. 5. The stop valve may be conveniently provided with a ball 47 contained in a suitable socket piece 48 and held to its seat 49 covering the inlet opening to the pipe 46 by means of a spring 50, the lower end of which rests upon a perforated plug 51, Athe perforation thereof leading to the interior of the lubricating tank 21.

`From the construction described it will be noted that as the plunger or piston 24 descends and causes a spray of lubricant or oil to be impingcd upon the awls 9 for the time bei in inactive positon, the ball 47 will be he d to its seat aad close the opening to the pipe 46; but, as thepiston rises in response to its sprin 25, the partial vacuum formed in the vlubrlcating tanlr will cause the ball 47 to drop from its seat 49 and piern vmit a suctionto be exerted through the pipes `46 and-42, thereby 'causing withdrawal of 4 the supply opening 52, F ig. 4, the to 353 of whichis disposed below the top 'of t e tank so that the tank can never be completely filled. The inlet opening 52 may be conveniently closed' by means of a screw plug 5d, or otherwise.

From the characteristics of the invention as hcreinbefore set forth'in connection with f the'illustrated form thereof, it will be noted that, when the awls are piercing the Work and are consequentlyin operative position, the guide pin lli will not contact with the arm or lug 3l so that the lubricating device will lihevisefremain inactive. i/Vhen, hoW- gever, the awls are in their inoperative position, as indicated in Fig. a, and the crosshead descends, the pin le will contact with the arm or lug 3l carried by the piston 'or plunger 211 and Willdepress the same, thereby forcing a spray ot' lubricant through the aspirator and onto the awls which are at the time inclosed by the casings 39 and 18, and upon upward movement of the cross-head any surplus lubricant Will be drawn from the botgtom of the casing back into the tank ai'ltcr passing through ay suitable strainer.

Obviously changes and variations may be made in the Various elements which aredescribed as a convenient form ot' thc inven' tion Without departing romthe true scope or spirit thereof, which is definitely set forth by the claims, andwhile herein the a-Wls or pricking devices are described as being lubricated, it will be apparent that Where desired the drivers for driving the nailsV or fasteners may be lubricated and the term nicher-sy or pricking devices herein is 'intended to be inclusive of drivers.
