CO~EYO~ '`KIRT ANI:! HO~DER
~ACX~;ROUND OP THE Il~'VENTION
Heretofo.e, s~irt board devices have involved arrangements which because of _apid wear-by the moving conveyor belt, necessitated frequent replacement, or constar.t adjustment which, with the arrangements used, was difficult and because of the continuous wear on the d~vices it was impossible to maintain an effective and continuous seel between the skirt boards and the moving belt.
- 10 It has been the general pr~ctice to utilize skirt boarding on uonveyorsto provide a seal between the moving cGnvevor belt and the stationary bin, or chute, where ma-terial i~ discharged onto the belt. This particuiar point is ~ery important to ~eal because it is here that a great per-centage of the dirt encountered thrGughout a plant finds its source. Material escaping from the conveyor at this loading point becomes scattered throughout the plant and rapresents a .
loss of the material conveyed.
~. Prior skirt boards were constructed from resilient material, such as rubber or the like, and were mounted on tSe conveyor housing by some means whic~ afforded manual adjustm~nt, in an effort to mate the board with the conveyor belt in some such manner as miqht form an adequa~e seal~nq relationship.
The ~eal was extremely difficult to maintain because of the wear resulting from the abrasion by the cons.antly traveling conveyor belt and which made the frequent adjustments re-~uired, almost .impossible for maintenance personnel in the plant to cope with and unless the adiustment was attended to at regular intervals it w3s not possible to prevent the material frcm escaping from the conveyor system.

............... ~.~ ....... . - '~
Conventional skirt board installations heretofore have provided arrangements where it was possible to adjust the skirt boards to obtain a sealing engagement with the conveyor belt but generally, these prior skirt boards were bolted in place and it became a major operation to perform the adjustments. The system had to be completely shut down, the bolts loosened, the skirt boards adjusted and then the bolts retightened and each time an adjustment was required these same steps became necessary to perform and if any resemblance of an effective seal was attempted to be maintained, the operation had to be repeated quite frequently.
The present design for a skirt board installation utilizes an inventive concept which avoids the problems of such prior art devices and overcomes the various short-comings inherent in the structures heretofore relied upon.
According to the present invention there is provided a skirt board installation for a conveyor having a travelling belt, the installation including at least one mounting plate and at least one skirt board section connectable to the mounting plate and disposed above the belt and adapted to contact the belt. Slide and guideway interlocking connection is provided between the mounting plate and the skirt board sections allowing generally vertical movement of the skirt board sections with respect to the mounting plate. Friction means is disposed between the mounting plate and the skirt board section adapted to permit sliding of the skirt board section toward the conveyor when a predetermined force is exceeded, but to retard movement of the skirt board section away from the belt.
The improve~.ents aforded by this invention provide a simple and convenient means for installing the skirt ~ boards and for adjusting them relative to the moving belt.
This adjustment can readily be made merely by tapping in-dividual skirt boara sections to move them downwardly to positions in enaagement with the belt, which can be accomplished without the need for stopping the belt, thus avoiding complete shut-down of the s~stem.
By thus mairltaining the seal ng relatioship 0 between the skirt board and the conveyor belt more o less constan~ the escape of material from the belt is prevented ` and the high labor costs of cleaning uv this lost material ic avoided. Present EPA rules reguire that plants be ke~t very clean and in view of which any material escaping from the conveyor system must be cleaned up and with prior skirt board arrangements it was not possi~le to work arour.d a moving conveyor bet so that it became nec-ssary to shut down the conveyor sy~tem to adjust the skirt ~n an effort to obtain a more effec:tive seal and to clean u? the lost material.
:0 . `Shutting down the conveyo:- system for these pur-poses resulted in a serious loss of valuavle production time so that the capability of the present skirt board arranqement to enable the individual skirt board sections to be tapped into ergagement with the belt to maintain a maximum sealin~ condition ~reatly reauceC, or el~minates, the necessity for clean-up operations and stoppage of the conveyor system.
O~JECTS OP T~E I~.~ENTION
It is a primary purpose of this invention to ` provide a sealing installation between a stationary bin, or loading chute, and a traveling conveyor belt which effectively prevents the escape of material and which `
, . .
:
may be readily adjusted to maintain a substantially continuous sealing relationship with the belt.
The principal object of the invention is the provision of a skirt board installation for conveyors including a plurality of skirt board sections individually adjustable.
An important object of the invention is to provide a s~irt board installation for conveyors having a plurality of skirt board sections interlocked together at their 10 adjoining vertical edqes and capable of individual relative vertical movement.

DE~CRIPTION OF rREFERP~ED FMBOD}MENT
- As shown in Pigure 1, a hopper bin, or chute 10, is mounted to discharge its contents onto a traveling con-veyor belt system 11. The conveyor belt runs on rollers 12 located respectively at opposite ends of its reach and the conveyor belt surface is supported by idler rollers 13 which carry the conveying surface in a trcugh-like shape by reason of the inclined disposition of the side rollers relative to the bottom center roller ~see Figure 2). Rollers 14 at spaced intervals support thc under side of the conveyor belt system.
~he bin, or chute 11, discharqes directly onto th-conveyor belt 11 and in order to prevent escape of any matsrial by leakage at the side and rear edges of the chute, a skirt board installation 15 is mo~.nted at thesë edges to '0 seal these areas against the escape of material deposited on the belt into the surrounding area beyond the conveyor system. ~he skirt board installation includes a mounting ~late 16 a~apted to be secured on the face of each side wall of the chute 10, here shown as being riqidly attached ~y ~eans of welding 1~. The mounting plate 16 is proviaed with a plurality of vertical slides 18 at longitudinzlly spaced intervals upon which a plurality of separate skirt - board,sections 19 are adapted to be mounted for relative vertical sliding movements and as best sho-~n in Figures 4 ~ and ~, these slides are of dove-tail section whereby to ~ . . .. .. . .. .. .
provide an interlocking connection with the s~irt board sections which have complcmentally shaped guide~ays ~0 closely fitting and operatively engaging the slides 1~. Thus, the s~irt board sections are restr2inoa against relative longi-tudinal displacement but may be moved vertically on the mounting plate 1;des 18 without affecting their longitudinal position relative to each other and to the mounting plate 16 The individual skirt board-sections 19 have interlocking connections at their vertical edges with -10 adjoining skixt board sections and these connections ta~;e the form of a vertically extending slide ~1 of round section on the edge of one skirt board section and a complementally shaped guioeway 22Ofround shape, on the adjoining skirt boa~d section. qhis relationship is best indicatea in Figures 4 and 5. Th~s, the individual skirt ~oard secticns 19 are ; adapted to hava relative vertical slidiny move.. ent with respect to the mounting plate 16 and to each other, without aff~cting their interlocking relationship with either.
As best shown in Figure 5, the outer face of each of thé vertical slides 18 is provid--d with hori~ontal serrc-tions 23 w~ich are shaped to facilitate movement of the skirt board sections 19 in a downward direction but to resist, or .
retard upw2rd movement thereof, as best indicated in Figurr 3. Thus, zs thc skirt board sections are adjusted downwaraly to enqage the belt 11 for more effective sealing purposes, the adjusted position thereof is retained by the serrations engagement with the inner faces of the skirt board sections.
It can readily be understood that an individual s~irt board section, or for that matter, several such sections, can be removed vertically and replaced without affecting adjoininq sections. ~his is possible because of the relat;vely verticai slidiDg movements permitted by the interlocking connections _ ~ _ A~
18~20 ana 21/22 between the sections 19 and mountin~ plate 16 ana tbe adjoining skirt board sections; respectively.
To facilitate sliding movement of one or more individual skirt board sections an opening, or recess 24, is provided in the outer face of each such section and when it is nece-ssary, or aesirable, to remove one or more sections, a suitable tool-can be insertea in the recess 24 for the purpose of prying, or slidinq, the section out of the assembly. When inserting a new skirt board section, or when adjusting one or more sections toward the belt, it is necessary merely to tap the top edge of the section with a suit3ble hammer, or mallet, to drive the individual sections in a generally downward direction for a ~ore effective sealing engagement with the conveyor belt 11.
These operations may be performed w_thout shutting down the conveyor, if desired, in view of the simplicity of the operation affordea by this mounting arrangement. Only simple relative sliding movements o: the skirt board sections are involv~d in making these adjustments.
The description of the invention hereinbefore makes reference to relative vertical movements of the skirt board sactions with respect to each other and in reiard to the mounting plate ~ut it must be pointed out that this does not require that the skirt board sections actually move in a directly vertical direction. ~he generally ver-tical movements of the sections may include a component of movement whereby the sections would move toward and away from the conveyor be t, as by means of inclinea guideways and slides, disposed at an angle such as would cause the sections to move generally vertically toward and away from the belt, Ag .
The mounting plate 16 may be fabricated from metal in the form shown, as preferred, but the skirt board sections 19 are nonmetall;c and may be made from rubber, or a suitable plastic material such as might be consistent wit~
the type of service to be encountered with an installation such as herein proposed~ The bottom edge of the skirt board rides on the belt 11 and therefore must be capable of with-standing this type of wear. However, the skirt board of this invention is highly adapted to this type of service and L0 may readily be adjusted to compensate for any wear that may occur on the bottom edge of the skirt board sections as a result of the running belt in engasement therewith, merely by .
tapping the sections on their upper edges with a hammer, or the like, to move them downwardly, as necessary, to take up .
any develo~ed clearance, which otherwise might result in leakage of the discharged material.
MODIFI~D SKIPT BOARD EMBODIMENT
As illustrated in Fig~re 6 a modification of the s~irt board sections 79 is shown wherein the skirt boa-d sections are of the same general dimensions as before and have simil1r slide and guideway features 21 and 22, respec-tively, of round section, at their opposite side edges an.
an actuating recess 24 in the front face thereof. ~owever, this skirt board section utilizes a slide arrangement and guideway ~or association with the moun~ing plate that is simi-lar to the slide and guideway arrangement 21/22 of round section whereby all of the slides and complemental guideways are of similar round section. The skirt board section on its inner face is provided with a pair of longitudinal spaced guideways 25 of round shape designed to be comDlemental to a slide of round section on a modified mounting plate (not shown).
~ p ~,~ _ 9, _ .
, . . 11~5786 In this ~orm of the invention the r ~ d sY~ion ~hicl~
slides on the mountin~ plate 16 may al~o be constructed to '' retard upward movement of the skirt board sections l9 once - --~
adjustment thereof has been attained. For this purpose the round section slidingon the mounting plate may comprise threaded rod sections secured on the face of the mounting plate lG by welding or the like. The guideways 25 in the skirt board sections which engage the slides on the mounting plate may be smooth on their inner surfaces or they might be provided with generally horizontal ribs on their rounded inner surfaces which would relate to the threaded ~ortions - on'the ro~nd slides in a manner to retard upward movement of the skirt board sections once they have been adjusted' downwardl~ into positions bearing on the conveyor belt 11.
The skirt board sections I9 of this type will - function relative to a mounting plate and in respect to each other just as the preferred form does but the modified - arrangemert facilitates manufactur~ inasmuch as all of the - slides anc guideways are of simila: design.
MC~DIPIED SXIRT 80AR1~ AND MVUNTIN~ PLATE
Figure 7 illustrates a fnrther modification of the skirt board'installation which involves changes in the mounting plate as well as the skirt board section. The outer face 26 of the mounting plate 16 310pes inwardly from top to bottom so that the dovetail sliaes 18 on this face are in-- clined at an inward angle whereby the skirt board sections 19 mounted'on the mounting plato by means of the slides 18 ana complemental guideways 20 in the skirt board sections, are disposed at a similar inclination and engage the conveyor belt 11 at th;s anglc. The skirt boards are movable toward or away from the belt on the slides 18 at the angle of the ~ 7 ~ . . . . . ~ . .. . . ..... . .
.
.
front surface 26 in making any adjustment of the skirt board sections rclative to the conveyor belt.
The skirt board sections 19 in this form of the invention incorporate a modified slide and guideway arrange-ment at their side edges which may be described as 'J-shaped.
Each skirt board section 19 has a V-shaped slide 27 on one side edge, a complementally V-shaped guideway 23 on - the opposite side edge so that, in operative oosition, ', adjoining skirt board sections interlock against relative lateral displacement just as in the,previous forms of the invention and are relatively slidable in the same manner as the previously described versions.
~UMMARY
From the foregoing it will be seen that there has been provided a skirt board installat~on fox use with ' a conveyor belt wherein individual skirt board sections are r , independently movable toward or away from the conveyor belt for adjust~ent, or removal and renlacement`ana wherein the skirt board sections have interloekingengagement with a mounting plate and with respect to each other to main-tain operative relationship while permitting adjustment of one,or more sections without the necessity'for shuttinq down the conveyor operation. ~he interlocking connections between skirt board se~tions and with respect to the mount-ing plate afford advantages not heretofore available in maintaining al~-gnment of the skirt board sections and in-,dependent adiustment and renewal.

The outer face 26 of the mounting plate 16 310pes inwardly from top to bottom so that the dovetail sliaes 18 on this face are in-- clined at an inward angle whereby the skirt board sections 19 mounted'on the mounting plato by means of the slides 18 ana complemental guideways 20 in the skirt board sections, are disposed at a similar inclination and engage the conveyor belt 11 at th;s anglc. The skirt boards are movable toward or away from the belt on the slides 18 at the angle of the ~ 7 ~ . . . . . ~ . .. . . ..... . .

front surface 26 in making any adjustment of the skirt board sections rclative to the conveyor belt.
The skirt board sections 19 in this form of the invention incorporate a modified slide and guideway arrange-ment at their side edges which may be described as 'J-shaped.
Each skirt board section 19 has a V-shaped slide 27 on one side edge, a complementally V-shaped guideway 23 on - the opposite side edge so that, in operative oosition, ', adjoining skirt board sections interlock against relative lateral displacement just as in the,previous forms of the invention and are relatively slidable in the same manner as the previously described versions.
~UMMARY
From the foregoing it will be seen that there has been provided a skirt board installat~on fox use with ' a conveyor belt wherein individual skirt board sections are r , independently movable toward or away from the conveyor belt for adjust~ent, or removal and renlacement`ana wherein the skirt board sections have interloekingengagement with a mounting plate and with respect to each other to main-tain operative relationship while permitting adjustment of one,or more sections without the necessity'for shuttinq down the conveyor operation. ~he interlocking connections between skirt board se~tions and with respect to the mount-ing plate afford advantages not heretofore available in maintaining al~-gnment of the skirt board sections and in-,dependent adiustment and renewal.
