- BACK AND TUBING FEEDING AND s vEEING MEANS. 2

To all whom it may concern:

Be it known that I, EDWARD 'DANNER, a citizen of the United States, and a resident. of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and ticularly in connection with apparatus for continuously forming molten material, such for instance as glass, into cane or tubing,

and has for its objecfthe provision of mechanism for continuously drawing cane or tubing: from a forming apparatus and successively .severingit into sections of predetermined length in a simple and eflicientmanner.

The invention is fully described in the following specification, and while, in ,its

broader aspect, it is capable of embodiment;

in numerous forms, a preferred einbodiment thereof is illustrated in the accompanying drawings, in which Figure 1 is a top .planviewof an apparatus embodying the invention, with a part of the work brealn'ng-olf and delivering mechanism removed.

Referring to the drawings, 1 designates the frame of the apparatus, which frameis preferably in the form of a platform and mounted on a set of wheels 2 to facilitate a .moving of the frame from one position to another. The work A, which may be of continuous tubular or bar form,first passes between a pair of guide rolls'3, which are operating portions of a pair of upper and lower workfeeding chains 4, 4. These feed chains are mounted in vertically spaced relation on respective

setsof sprocket wheels

5, 5, the front and rear sprocket wheels of V shafts 6 and 7 and the front and rear set of shafts 6, 7. are mounted in the lower portions of respective bearing standards 10,

11, (shown in detail in Figs. '8, 9 and 10,) which standards are fixedly mounted on and rise from the frame 1 at one side portion thereof andin longitudinally spaced relation with respects-thereto. The upper set of shafts 8, 9 are mounted in respective bearing blocks 12, 13, which are mounted for vertical adjustment, on the adjacent sides of the upper end portions of the respective bearing standards 10 and 11 to permit a vertical adjustment of the upper set of shafts with respect to the lower set.

85 mounted on vertical spindles at one end of the frame 1, and then enters between the .co-

vertically disposed position in the respective bearing standards 10 and 11, whereby a turning of the screw shafts will eifect a vertical adjustment of the respective bearing blocks 12 and 13. The upper ends of the screw shafts 14 and 15 are connected by respective sets of miter gears 16 to a-shaft 17 which connects the upper ends of the bearing standards 10 and 11, being. suitably journaled therein, and hasa crank 18 at its rear end to facilitate a hand turning thereof in one direction or the other as it may be desired to effect a raising or lowering of the bearing blocks 12, 13.

The working'portions of the chains 4, 4 are held in yielding contact with the work A, as it is fed forward thereby, by the cooperative action'of a stationary platform 19, over which the working portion of the lower chain travels in contact therewith, and a plurality of pressure plates 20, which are mounted above the working portion of the upper chain in a manner to cause said chain to have a yielding downward pressure on the work. The platform 19 is mounted on brackets 21, 21, which aremounted on and rise from the frame 1. Each pressure plate 20, in the present instance, has a stem 22 projecting upward therefrom into a registering socketed part 23 of an overhead frame part 24, which frame part is carried at the upper ends of a pair of

upright posts

25, 25. Each post 25projects downward into a registering opening 26 in the frame 1 (see Fig. 6) for free vertical movements therein and has a sprocket-wheel 27 threaded thereon and resting at the lower end, of its hub on the frame 1, whereby a turning of the sprocket wheel 27 will effect a vertical'a'djustment of the post. A set screw 28 removably secures the frame part 24 to each post 25. A pair of plates 29 are bolted to the frame 1 at opposite sides of the lower end portion of the hub of each sprocket wheel 27 and engage over an annular flange on said hub portion, as shown in Figs. 6 and 7, to rotatably hold the sprocket wheel to the frame 1. The sprocket wheels 27, 27 are connected by a chain 30 to cause a turning of the sprocket wheels in unison.

A coiled compression spring 31 (Fig. 6) is mounted in each socketed part 23 and acts against the respective stem 22 to cause its pressure plate 20 to have a yielding downward pressure on the working portion of the upper feed chain 4. vIt is evident that the pressure of the plates 20 on the chain and the consequent force of gripping of the work A by the working portions of the two chains 4, 4 can be adjusted to suit the requirements of the particular case by a raising or lowerring of the posts 25 This adjustment is also effected upon a changing of the size of the work operated on.

The links of each chain4are connected by' shafts 32 (see Figs. 12 and 13), and alter nate'shafts carry rollers 33 at their ends which coact with the respective platform 19 and pressure plates 20 when traveling therebetween. Each chain 4 is also provided in equ-idistantly spaced relation with chairs 34,-

The pad 35 comprises a holder member 35; j i

and a work engaging part 35*, which is held in position on the shaft by the holder 35. The body portions of-each

pad part

35 and 35 are of rectangular form and substantially of the same length, with the side edges of the holder part 35 projecting beyond the side edges of the pad part 35 to form extensions 35 for folding over the side edges of the part 35*, as shown in Fig. 13. The ends of each of the padparts are also provided with tongue extensions 35, with the extension 35 of the holder part of greater length than the extensions 35 of the pad part to permit an endwise doubling of the holder 9 extension 35 over the pad part extension,

35. The pads 35 are secured to the chairs 34 by a doubling of the

end extensions

35, 35 under the respective end portions of the chair 34, as shown in Fig. '12. The pads on the separate chains 4, 4 are arranged to have opposed-engagement with a work piece A passing therebetween.

The guide rolls 3, 3, which are disposed at the rear of the feed chains 4, 4 are carried by respective vertically disposed spindles 36, 36 (see Fig. 11), which spindles are pivoted intermediate their ends, as at 37, to respective vertically projecting carrying arms 38,

and mounted on a horizontally disposed shaft 39 in respective right and left threaded 1 which arms are enlarged at'their lower ends connection therewith, whereby a turning of the shaft with respect to the bearing arms 38 will cause said arms to have like inward and outward adjusting movements. The shaft 39 is rotatably mounted in the inner forked end of a bracket 40, by which it is held against endwise movement, said bracket being fixed toand rising from the rear end of the frame 1. The lowerends'of the spin dl'es 36 are disposed at the inner sides of the carrying arms 38'and-each is yieldingly connected at its lower end to its carrying arm.

and in thrust engagement at its inner end with said arm. It is evident that this yielding connection between the spidles' 36 and their carrying arms causes the

rolls

3, 3 to exert an opposed yielding pressure against the Work A passing therebetween.

Power for driving the work feeding chains 4, 4 is derived, in the present instance, from a motor 43 mounted on the platform 1 (see Fig. 1), the shaft of said motor carrying a pinion 44 in driving connection with a gear 45. The gear 45 is mounted on a shaft 46 that is j ournaled transversely of the frame 1 in a suitable bearing 47 provided thereonand carries a pinion 48 in mesh with one of a pair of meshing gears 49 disposed one above the other and carried one by the chain driving shaft 6 and the other by the chain driving shaft 8, which shafts for such standard 10 across the frame 1 and are journaled in a bearing standard 50. The upper shaft 8 is provided intermediate the

bearings

12 and 50 with a flexibly connected section 8 which permits a vertical adjustment of the sprocket wheel carrying end of the shaft with respect to the gear carrying end thereof. It will be understood that the gears 44,

45, 48 and 49 are interposed between the motor and chain shafts for the purpose of reducingthe speed of driving of the chains the desired extent with respect to the speed of the motor shaft, and that such connection may be changed to suit the exigencies of the particular case.

The work" A, after passing between the feed chains 4, 4, enters between a pair of horizontally spaced guide rolls 51, thence passes over a vertically yielding pressure table 52, and next enters a registering portion of the work breaking-off and deliverywheel 53, by which the work A is intermittently broken into sections of predetermined length and then delivered from the machine. It is preferable to provide rearwardly flaring stationary guides 54 and 55in position to respectively guide the work between the rolls 51 and into the registering receiving portion of the wheel 53, should the work bar or tubing break off at the rear of either of said members, as frequently occurs when the work is of a brittle nature, like glass. The guide 54 is carried by an arm 56, which fixedly rises from an adjacent portion of the frame 1, and the guide member'55 is carried by a bearing standard 57 rising from the forward end portion of said frame. The guide rolls 51 are mounted in a similar manner to the guide rolls 3, 3 and the specific mounting of the same need not therefore be described. 4 o a The pressure table 52 is elongated lengthwise of the work and is pivoted adjacent to its rear end, as at 58, to a supporting stand.-.

ard 59, which rises from the frame 1. The

forward end of the table 52 is caused to have yielding .upward pressure exerted thereon against the under side of the workA (for the purposehereinafter described) by a the point of upward-pressure of the table 52 on the work as occasion may require,

A shaft 61 is mounted at its' ends in hearing

standards

62 and 63 rising from the frame 1 and is disposed at one side of the pressure table 52, the right hand side thereof, in the present instance, with respect to the direction of feed of the work, and in parallel relation to such direction of feed. This shaft is driven at a high rate of speed by a motor 64, which motor is mounted on the frame 1 and has belt and pulley connection 65 with the forward end of said shaft.

A pulley 66 is splined on the shaft 61 for longitudinal movements thereon between its bearings, and the hub ends of the pulley are preferably ext-ended therefrom in sleeve form,,. as shown at 67 (see Fig. 15). Bearing

sleeves

68 and 69 are respectively mounted forfree rotation on the front and rear hub ends 67, and these sleeves form bearings for the respectivearms of a forked slidehead '70, which straddles the pulley 66, thusshaft transversely thereof; The outer end of the head 7 O carries a bearing fork 71, the arms of which are horizontally spaced and form bearings for a horizontally disposed shaft 72 and carry ball bearings 73 therefor (see Figs. 15 and 20). pulley 74 keyed thereto intermediate the bearing 'arms of the fork 71, and this pulley is connected by a belt 75 to the pulley 66. The fork 71 is shown, in the present instance, as having a stem 71 projecting from the inner end thereof and into a registering socket '70 in the outer end of the slide-head 70, for reciprocatory movements therein, it being prevented from turning therein, however, by a key (Fig. 16). A nut 71 is threaded on the inner end portion of the stem 71 and is held in thrust contact with the outer end of the slide-head 70 by the belt a 75, which connects the

pulleys

66 and 74. A tightening or loosening of the belt may be effected by turning the nut 71 on the stem,'and the nut is locked in adjusted position by a pin 71, as shown in Fig. 16.

A work cutting wheel 76 is fixedly mounted on one end of the shaft 72, the forward The shaft 72 has a.

contact with the top of the work by a down- 7. Ward rocking of the slide-head 70, the forward and backward strokes of said wheel with respect to the table 52, upon a forward and backward reciprocation of the slidehead 70, being indicated by the dotted lines a, b in Fig. 24, the lower line designating the forward stroke and the upper line the rearward stroke of the wheel. It will be noted from the lower line athat the lower edge of the cutter wheel 76 moves downward into ,contact with the work A during the initial portion of its stroke, then remains for a short period in contact with the work and then rises from engagement with the work during the final portion of the forward stroke, the point of contact of the wheel with the work being in opposition to the forward yieldinglysupported end portion of the pressure table 52. The means for effecting such vertical movements of the cutter wheel will be hereinafter described.

The wheel 76 is intended to cut a surface groove in the work each time it is moved into contact therewith, such groove not beingof sufiicient depth, however, to cause a severing of the work at such point at this period in a cycle of operations of the machine, the finalsevering action being caused by the action of the wheel 53 on the work,

which wheel-is intended to intermittently 1.. revolve andexert a transverse strain on the "'-work advance of the cut to effect a breaking ofi of the work at such weakened point.

The frictional coaction of the wheel 76 with the work also causes a localized heating of the work at the point of contact so that a strain up within the heated part thereby facilitating a breaking ofl of the work at the groovedpoint.

A lubricant is retained within one bearing armof the fork 71 by plates 77 secured toopposite sides thereof while plates 7 8, are secured-to opposite sides of the other arm of said fork to retain a lubricant in contact with its bearing.

A guard or housing 79 for the cutter wheel 76 is secured to the outer plate 78 by screws 80 or in any other suitable'manner.

A hand adjusting screw 81 is vertically threaded into the top of the forwardfork arm 71 and carries a block 82 for vertical adjustment therewith, said vblock projecting transversely from the screw through a registering slot or notch 83 in the outer plate 78 and carryinga pair of work guiding -finqers 84 at its outer end. Thefingers '84 are carried at their ,upper ends by a commonpivot screw 85, projecting from the forward end of the block 82, and'pro'ject outward,.

downward and then inward between the outer plate 78 and the wheel inclosing portion ofthe guard 79, and have their lower uds disposed in spaced relation below the ower horizontal edge of the cutter wheel 76 and in position to permit the passage of the Work A therebetween. These guide fingers follow the course of movements of the cut-- drawn toward each other by a coiled contractile spring 86, and the inward relative movements of said fingers are limited by stop-

nuts

87, 87 which have right and left threaded connection with an adjusting screw 88. The screw 88 is journaled for free rotary movements in a pair of spaced bearing bosses 89, projecting from the outer plate 78, and carries a collar 90 between said bosses to prevent endwise movements of the adjusting screw therein. The nuts 87 are positioned to coact with the inner edges of the'respective guide fingers 84 to limit the inward movements thereof, and a turning of the screw 88 in one direction or the other causes the nuts to move inward or outward 'in unison thereon, as is apparent. It is eviwill effect a corresponding raising or lowering of the guide fingers 84 as it may be desired to vertically adjust them with respect to the work.

A guide plate 91 is disposed in rear- Wardly inclined position below the fork 71, having its rear end attached to the rear arm of the fork 71, as at 92, and its forward end adjustably connected to the forward fork arm by a U-shaped yoke 93-, the legs of which project upward from the plate 91 and are provided with vertical slots 94 for receiving a bolt 95, projected through the lower portion ofthe fork arm. The plate 91 terminates at its forward end adjacent to the rear side of the fingers- 84 in position to guide an end of the work A with respect to said guide fingers should the work become broken off at a point at the rear of the guide fingers.

The means employed forreciprocati'ng the slide-head 70 on the shaft 61 will now be described. Mounted in bearingblocks 96, which rise from theframe 1 at the right hand side of the shaft 61, are a pair of shafts 97, which are transversely sp'aced lengthwise of said frame and each carries a sprocket wheel 98. These sprocket wheels are connected by a sprocket chain 99, and

such chain is provided at a point thereon with a transversely disposed shaft 100 car rying a roller 101 at each end thereof A yoke or slide-frame 102 is mounted for sliding movements-lengthwise of the shaft 61 on a slide-base 103 and has arms 102" projecting therefrom and carrying the

respective sleeves

68 and 69, which in turn carry the slide-head 70 (see Figs. 6, 15 and 22).

The outer side of the yoke or slide-block 102 is provided with a boss 104, which coacts with a pair of plates 105 secured to its outer end to form an opening 106, which takes over the chain 99 and sprocket wheels carrying the same, and is permitted to have backward and forward movements over said chain and sprocket wheels. The side walls of the opening 106 are provided with vertically disposed guide grooves 107 in which the rolls 101 on the respective ends of the shaft 100 travel. It is evident that the yoke 102 will have backward and forward movements, communicated thereto by "the rolls 101 as said rolls'follow the successive backward and forward movements of the portion of the chain 99 to which attached when said chain is driven, and that said rolls will move vertically in the grooves 107 as they pass around the respective sprocket wheels with the chain. The plates 105, which are secured to the outer side of the boss 104, are spaced at their inner ends to permit the passage of the shafts 97 therebetween as the yoke is reciprocated. This fornrof driving means for the cutter wheel' carrying parts causes said parts to have rapiduniform forward and backward strokes which are slowed up adjacent the limits thereof and enable the major portions of each stroke to be maintained at a uniform speed which is the same as the speed of forward feeding movement of the work, thereby causing the cutter wheelwhen acting on the work to move therewith without any relative variation in speed.

108,108 (Fig. 15) designate lubricant retaining collars, which are secured to the outer sides of the yoke-arms 102 in encircling relation to the shaft 61 and retain a lubricant in contact with the ball bearings 109 for the respective"

sleeves

68 and 69. The shaft 97 which serves as the drive shaft for the chain 99 has a sprocket wheel 110 thereon, which is connected by a chain 111 to a sprocket wheel 112 on the feed chain driving shaft 8 (see Figs. 1 and 6), said shaft 61 in parallel relation thereto and has one end j ournaled in the bearing bracket 63 and provided without said bracket with a hand-wheel 115 to facilitate a hand turning of the shaft. The shaft 114 has nuts 116 v mounted on opposite end portions thereof in'respective right and left threaded connection therewith, said nuts having coaction with registering portions of the slide-base 103, whereby'they are held against turning and permitted to move lengthwise of the shaft 114. A coiled compressionspring 117 is mounted on the shaft 114 at eachside of the yoke boss 113, and this spring is intended to coact with the respective nuts 116 to serveas a bumper for the slide frame or yoke 102 and to facilitate a reversal of the movement thereof. It is evident that a relative inward or outward adjustment of the nuts 116 can be effected by a turning of the shaft 114 in one or the other direction and a consequent inward or outward adjustment of the springs 117 accomplished.

The means employed for vertically rock- 1 ing the slide-head to raise and lower the cutter wheel 76 with respect to the work at predetermined points in a forward stroke of said slide-head will now be described. A shaft 118 is mounted below the slide-head 70 before the vertical plane of the shaft 61, being journaled at one end in the bearing standard 57 and at its other end in a bearing bracket 119 secured to the adjacent end portion of the slide-base 103 (see Fig; 1). This shaft has connection through a pair of gears 120 (Figs. 1 and 6) with a short shaft 121 which is mounted in the bracket 119 and has bevel gear connection 122 withi the drive shaft 6 for the feed chains. driving of the shaft 118 is so timed'with respect to the speed of driving of the feed chains 4 and the reciprocatorv movements The speed of of the slide-head 7 0 that the-shaft 118 makes I one complete revolution for each complete .cycle of operations. of the machine, or a movements therewith, said wheel having a peripheral groove 124 and a cam working surface 125 provided circumferentially around different portions thereof (see Fig. 18) An arm 126 is carried atone end by the sleeve 68 on the shaft 61 and has its other end projecting transversely from said shaft under the slide-head 7 O'and terminatingover the cam-wheel 123 with a part126 thereof forked to straddle the grooved portion 124 of the cam-wheel. The arm 126 carries a roll 127 at one side of said forked portion in position to ride on the cam surface 125 of the wheel, whereb a rotation of the cam-wheel causes vertical rocking movements to be imparted to the arm 126 in accordance with the formation of said cam surface. A stud 128 projects upward from the free end por- .tion of the arm 126, in the present instance,

into a registering socket in the under side of the slide-head 70 and receives the downward end thrust of the lower end of aset screw 129, which is threaded down through a portion of the slide-head 70 (see Figs; 15,16 and 17). It is evident that a, vertical adj ustment of the cutter wheel 76 with respect to the work can be effected by an adjusting of the screw 129 in the slide-head, the slidehead being thereby raised or lowered with respect to the arm 126. The screw 129 is secured in adjusted position by a set screw 130. I

It is found in practice quite important to prevent the accumulation of dirt and particles of the work within the spline grooves 118" of the shaft 118, especially when operat ing on glass, as it is found that small particles of glass fall in said groovesandnot only prevent a free movement of the slide parts but sometimes cause a locking of said parts against movement. For this reason I have provided a cleaning gasket 131 at each end of the cam-wheel 123, each of said gaskets being set in a recess in the end of the cam-wheel and secured therein by a collar 132, which is secured to the end of the wheel b screws or in any other suitable manner (see Figs. 17, 18 and 19). Both the gasket and collar have spurs 133 projecting inward therefrom and fitting into the respective groove of the shaft 118. The splines 134 are held centered within the cam-wheels and prevented from pounding against and damaging the sp Us 133 of the gasket by set screws 135, W ich are threaded through the respective collars 132. and project through the gaskets in position to engage the respective ends of the splines 134.

The work breaking-off and delivery wheel 53 is journaled at its rear end in a part 57 of the bearing standard 57 and is disposed with itsjaxis parallel to but slightly offset from the line of travel of the work A, said wheel being disposed forward of the bearing standardby which its shaft is carried. The wheel is composed of a plurality of plates 138, which project tangentially from a circle concentric to its axis of rotation and are successively positioned therearound, six being employed in the present instance, and secured at their inner ends to respective sides of the shaft 137, which is made of hexagonal form in crosssection for such purpose, as shown in Fig, 4. The plates 138 cotiperate to form a plurality of pockets around the periphery of the wheel, which pockets are of a length corresponding substantially to the maximum length of the work piece sections to be cut or broken from the work bar or tube. The inner or rear end of each pocket is provided with an end plate 139 having an opening 140 therein flush at one side w th one of the bars 138 and through which the work enters a registering pocket of the wheel. Upon a turning of the wheel 53 in the direction indicated by the arrow in Fig. 4, after a predetermined length of the-work bar or tube. has been projected into a registering pocket thereof, the plate 139 strikes the work bar or *tube slightly in advance of the point thereof which was cut by the cutter wheel 76 and effects a breaking in two of the bar or tube at its weakened point. The turning of the wheel in addition to causinga breaking-off of work sections also moves the pocket containing the broken-off section either to or toward the section delivery position thereof and moves the next pocket in order in position for the advancing work to enter the same.

The intermittent turning of the wheel 53 is controlled by a set of gears 141 (Fig. 5) of the Geneva type, the pin carrying member of which is mounted on a shaft 142 intermediate the

shafts

137 and 118 and is in geared connection with the shaft 118 through the medium of the gears 143. The gears 143 are of like size so that a pocket advancing movement is communicated to the wheel 53 at each complete rotation of the shaft 118. i I

The operation of my machine is as follows: It will be understood'that the work bar or tube A advances from the furnace or other source of supply between the guide rolls 3, 3 and thence between the set of feed chains 4, 4, bywhich it is drawn forward at a uniform predetermined speed from the furnace or forming means, the gripping pressure of the working portions of the feed chains 4 on the work being regulated by a turning of the sprocket wheels 27 on the posts 25, which imparts vertical movement v to the frame part 24 and varies the tension of the spring 31 on the-stem 22 of the pressure plate 20. The feed chains 4, 4 and the sprocket wheels carrying the same, are also adapted to have relative vertical adjustment by a turning of the crank 18 and shaft 17 to which it is attached, which turning communicates rotary movements to the adjusting screws 14, 15 for the respective bearing blocks 12 and 13, which carry the shafts for the upper set of sprocket wheels 5. The work, after passing between the feed chains 4, 4, passes through the guide 54, then between the guide rolls 51, then under the cutter wheel 76 and over the pressure table 52, in contact with the latter, and thence through the guide member 55 and into a registering pocket of the work breaking-off and delivery'wheel 53. As the work advances the. slide-head 70 and other parts which carry the cutter wheel 76, and which connect said slide-head with the drive chain 99, are caused to be, reciprocally moved on the shaft 61 lengthwise of the direction of 'feed of the work and with the speed of movement of each forward stroke, at least, thereof the same as the speed of advancing movement of the work A. It will beunderstood that the shaft 118, which carries the cam-wheel 123,- has a single complete rotation at each cycle of movements of the cutr a predetermined portion of its movement,

after which the wheel is raised to its elevated position and maintains such elevated position during its rearward stroke, as shown by the dotted line b in Fig. 24:. The action of the cutter wheel 7 6 on the work causes a shallow notch to be cut in the surface of the work at the point .where it is desired to have the work subsequently severed or broken and the frictional coaction of the cutter wheel with the work in addition to 'cutting or notchi'ng the same also effects a localized heating thereof at the point of contact so that an abnormal strain is set up in the glass and renders it more brittle at such point to facilitate breaking off. The

point of contact of the cutter wheel with the shaft.

work is opposed to the end portion of the table 52, which bears upward against thework, thereby retaining thework in yielding contact with the cutter wheel during the cutting operation. The cutter wheel is driven at a high rate of speed from the motor 64, which has belted connection with the shaft 61, and said shaft in turn has belted connection with the cutter wheel The drive chain 99 is connected to one of the drive shafts for the feed chains 4, 4: and is driven at the same speed as said feed chains; \Vhen a predetermined length of work has moved into a registering pocket of the-breaking-off and delivery wheel 53 the wheel is given, in the present instance, a one-sixth turning movement, which causes the plate 139 at the rear-end of the pocket in which the work is feeding to strike the work slightly forward of .the notched or weakened point thereof, which effects a breaking in two, of the work at such point. Such movement of the wheel also moves the next pocket in order in position for the advancing work to enter the same preparatory to the next breaking-off movement thereof. It is thus evident that the work is cut and later broken off in sections of equal length during a continuousrforward feedlng thereof and that the cut-offsections are delivered from the pockets of the wheel 53 by gravity as the wheel is successively turned.

In the present use of the machine embodying my invention it is driven at a speed to cause an advancing or forward drawing of the work bar or tube at approximately 140 to 150 feet a minute. This, however, may be increased or diminished, as desired.

While I have herein shown and described one specific embodiment of my invention for lllustrative purposes and have disclosed and discussed in detail the construction and arrangement incident to one specific application thereof, it is to be understood that the invention is not limited to the detail or relative arrangement of the parts, but that it is capable of numerous modifications either in entirety or in the different sub-combinations thereof without departing from the spirit of the claims.
