YIELDABLE GUIDE FOR COATING IYIACHINES.

Application filed July 27, 1922.

To all whom 'it may concern Be it known that I, IRVIN F. DITTMAR, a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvement-s in Yieldable Guides for Coating Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in yieldable guides for coating machines and more particularly to guides adapted to be used in connection with machinesL for coating strips: of lumber in which the strip is passed through the machine on edge, the object being to provide a guide which is so constructed that it will yield so as to allow crooked pieces and pieces showing a variation in thickness to pass through without stoppage, which causes roller marks to spoil the pieces at the point of roller contact, thereby overcoming the dii'iculties now existing in having to stop the machine and remove the strip when it has become jammed in the guideway.

Another and further object of the invention is to provide a yieldable guide formed of superposed guiding members, each guide member being formed of spaced members held in proper relation with each other in Such a manner that they are capable of moving laterally in 'order to allow an'irregular strip to pass freely through the guide.

Other and further objects and advantages of the invent-ion will be hereinafter set forth and the novel features thereof dened by the appended claims. l l In the drawings, Y f

Figure 1 is a perspective view of a portion of a guideway constructed in accordance with my invention;

Figure 2 is a vertical sectionvthrough the same showing the manner of connecting the guide members of the guideway to the supporting members; Y

VFigure 3 is a vertical section through a slightly modified form of guideway;

Figure 4 is a vertical section through still anotherform of guideway;

Figure 5 is a vertical section through still another form of guideway; and- Figure-6 is va vertical section through an* other form o f guideway,

Serial No. 577,869.

In the drawing 1 and 2 indicate supporting members which are herein shown in the form of angle irons to which are adapted to be connected guide members 3 and 4C having notches 5 and 6 at the point of application of the coating so as to allow Ithe strip to be coated as it passes through the guideway.

rlhe upper guide 3 is formed of an invert# ed U-shaped strip of flexible material having its lower edges cut away to form a fe male guiding edge and the lower guide member t is formed of a U shaped strip of flexible metal having its upper edges cut away to form a male guiding edge.

The guide members formed with this particular construct-ion of guiding edges are especially adapted to receive strips of lumber having interlocking male and female edges and itis, of course, understood that the particular construction of the guiding edges can be changed to fit the shape of the edges of the strip to be coated and therefore I do'not wish to limit'myself to the use ofa guideway formed of guide members having any particular construction of guiding edges as I am aware that the conguration of the guiding edges can be readily changed to conform to the edge of the strip of lumber to be coated without departing from the spirit of my invention.

In the drawing I have shown'the guide member 3 connected to the support l by a bolt 9 `and spaced therefrom by spring washer l() in order to allow the legs of the guideway to expand and contract. The lower guide 4 is connected to the lower support by a bolt 11 which passes through one of the legs and is provided with

spring washers

12 and 13 in order to 'allow the legs of the guideway to expand and contract, it, of course, being understood that a number of bolts are employed for connecting the guide members to the supports and while I have shown means for connecting these guide members so as to allowthe inner leg of each guide member to expand and contract, I am aware that by rigidly connecting the guide members tothe support, the outer legs of the substantially U-shaped guide members will expand and contract so as to` allow a strip of lumber to pass freely through the guideway formed by said members 'and I do not wish to limit myself :to

any particular means for connecting the guide members forming the guideway to the supports, asI am aware that these members can be connected to the supports in various ways without affecting the operation of the members.

In the preferred embodiment of the in vention as shown in Figures 1 and 2, the guideway formed by the

guide members

3 and 4 is formed ot substantially Ufshaped members to form yieldable legs, while in Figure 3 the upper and lower guide menibers forming the guideway are Jformed of spaced strips of metal 14 and 15,' the upper strips 14 being spaced apart by tapering block 16 and secured together by aV bolt 17 on which is mounted a spring washer 18 which allows the spaced strips to move in respect to each other.

The spacedV strips `forming the guide member 15 are spaced v'apart by a tapering block 19 and are secured together by aj bolt 20' which passes through 'the 'block and is provided with a spring washer 21, ythe upper edge lof the-"strip being ciitaway to'form a male guidingY edge;

In this construction, the spaced strips forming the guide members 'are yieldably held together soasto provide a yieldable guideway for thestrip 'as it passes'therethrough, as` clearly shown. y 4

In Figure 4 I show the upper guide member 2Q `formed of spaced 'stripssecured' together by bolts QS'and 24" provided with spring washers 26 and spaced 'apart'at their upper end' by a block 'QZ'which allows the spaced members `constituting the guide member to'move in respect to one another, the lower edges being'cut away-to vform a temaley guiding edge. The lower guide member 28 formed'of" spaced stripssecured together by bolts'2'9 andSO carries spring washers 31 arranged betweenthe stripsv in such a mannerthat the strips 'are Jfree to move in respect to one another, theA lower "3 nut of the boltY 3() being drawn tight while the upper nutY ofthe b olt 29' is spa'cedffrom the strip so as toallowthe strips to yield in respect to one another, the upper edges of the strips being cutaw'ay vto'forin a :male guiding edge. f'

In Figure 5 of the drawing Il show a guideway formed of'upper andlower guide members 32- and" 33, the upper guidemeiriber 32 being formed offapair ofstrips'between which. is arranged an elastic Spacing member 34,l said 'strips being securedv toi gether and held so as to' `holdithe elastic strip under compression by Abolts which` areprovidedwithspring washers 36.

In Figure 6 I show a guideway formed of an upper guide member 40 and a lower guide member 41, the upper guide member being formed of .a Vpair of strips spaced. apart by elastic washer' 42 and secured together by bolts 43:carrying spring washers 44. The lower guide member 4l is Jformed of strips spaced apart by elastic washers 45 and secured together by bolts 46 and 47, the nut of the bolt 46 being drawn tight so as to 'place the elastic material 'under compression whiley the nut on the bolt 47 is loose in order to allow the strips to move in respect to one another lso that the strip will pass freely through the guidewav formed by th'eguide members.

'While in the" cha'wing I have shown various forms oi'"mounti'ng and constructing the guide members forming the guideway, I ain aware that various changes can be made without departing from the spirit of my invention and I' do not-wish'to confine myselfjto the use ofjany particular construction Aof spring washer as I' am aware that a washer having more than one convolutioncanbe used or a flat` spring could be substituted for the washer and the same result obtained. j

From the foregoing description it will be seen that I have 'provided a'guideway formed of a pair of spaced guiding members, each guide member having spaced guiding edges which are yieldably 'heldinl a predetermined position so als to allowthe guiding edges to expand andcon'trafct to conform tothe' shape ofthest'rip in itsjpassage*therethrough to prevent the strip Jfrom j ammingso that the speed of the machineffor coating the .st-rip can vbe increased and all danger o'ty having a: construction that' the stripjcan be readilyk placed between4 the guidewar land fed easily therethrough.

A'In' Figure 1 of the drawing I' have shown the guide` strips Band 4 forming the v'guideway with notches 5 and 6 and' while I have only shown aj portion kof the guideway with a pair 'ofopposingl notches, it is, ofcourse, understoodfthat-the guideway can be formed with any numberg 'otnotchesdesiredto meet the'speciiic-requiremeiitoffthe'coating'being applied. I5 am alsoawarethat the particular fshapegf'ofrthese; notches can` be changed to conform to the shape of the applying device.

What I claim is l. A guideway for coating machines comprising spaced guide members, each guide member having yieldably spaced guidin.r edfes.

A guideway for coating machines comprising spaced guides, each guide being formed of yieldably spaced members and means for yieldably supporting said guide.

3. A guideway for coating machines comprising spaced substantially U-shaped guides, one guide being provided with a male guiding' edge and the other guide with a female guiding edge.

e. A guideway for finishing machines comprising spaced notched guides, each guide being formed of spaced members yieldably held in respect to one .another and means for yieldably supporting said guide.

5. A. guideway for wood finishing machines comprising spaced guiding members,
