6 Claims.
This invention relates to forms for supporting composition material for curing in a baking oven and it is particularly adapted for carrying strips of romposition friction material for this purpose.
The object of the invention is to provide a form for curing strips of composition material which will be light in weight, strong and substantial in construction, and which will hold the material in a desired shape.
Another object of the invention is to support the material on the form in a manner which will permit the circulation of heated air between the material and the form to enable uniform curing.
And a further object is to provide a simple means for retaining the material in place on the form.
And a still further object is to provide adjustable means for retaining strips of material to be cured of different lengths.
I have illustrated the invention in a simple embodiment in the accompanying drawing and referring thereto Fig. 1 is a side elevation of the form with ma.- terial to be cured applied on one end portion thereof and the retainer bar partly broken away.
Fig. 2 is an enlarged transverse sectional View on the line 2-2 of Fig. 1.
Fig. 3 is an enlarged fragmentary longitudinal sectional view through an end portion of the drum.
Fig. 4 is a fragmentary View partly in section taken on the line 1-4 of Fig. 1 showing the adjusting means.
Referring to the drawing the forni comprises an elongated transversely curved face plate 5 having end plates 6 and one or more intermediate transverse brace plates l corresponding substantially with the end plates, the end plates and the brace plates being provided with edge iianges 8 which are spot welded or otherwise secured to the face plate to secure the parts together. Openings 9 are provided in the end and brace plates to lighten the weight. The openings in the end plates form convenient means for grasping the form when it is loaded with composition strips to transfer the form from the loading table to the oven, and the marginal edge about the opening may be turned or flanged at 9' to afford a better hand hold and prevent injury to the operators hands. The side edges or" the face plate project below the bottoni edges of the ends and reeniorce strips 1G having down-turned ends 1l nt against the bottoni edges of the end and brace plates and between the marginal edges of the face 55 plate, these reenforce strips being spot welded (Cl. ltd-34) or otherwise secured 'to the flange at the bottom of the end and brace plates and to the face plate.
A sheet 12 of reticulated material, such as wire mesh, is applied to the outer side of the face plate and is snugly secured thereto by bending the 5L marginal edges 13 around the lower edges of the face plate and the ends 11 of the reenforce strips', and the marginal edges of the retlculated sheet may be secured in place in any suitable manner, in addition to bending them as just described, as by means of rivets 12. Additional reenforce and stiffening strips le may be spot welded or otherwise secured to the strips 10. The reticulated sheet is out away at 15 to expose the face plate 5 on opposite sides thereof and at spaced intervals between the ends of the form and these exposed portions of the face plate have slots 16 therein. Bolts 1'? project through these slots and carry spring hooks 18 which are adapted to receive the retainer bars 19 which are preferably channel shape in cross-section'and arranged in place with the weh in Contact with the strips and the anges outwardly directed. Tubular inserts 19 are secured in the channels to bear against the hooks 18 and pressure is applied to force the bars downward canse the inserts to spring the hooks outward to create suicient tension to hold the bars in place. The flat contact face of the web of the channel bar retainer has restricted Contact with the surface of the strips and bears against the surface of the strips without indenting or marking them. The inner ends of the bolts are provided with wing nuts 20 which are accessible through tle 7oottom of the form and through the openings 9 in the end plates. The hooks 18 may be adjusted on the face plate by moving the bolts in the slots 16. The invention is particularly adapted, although not exclusively, for holding strips 21 of composition friction material which is suniciently soft when made to adapt itself to the outer face of the reticulated sheet, or to be easily shaped to nt snugly thereon, and after a desired number oi strips 21 are so applied to the form the retainer bars 19 are dropped into the hooks 18 and against the end portions of the strips and are forced downward in operative engagement with the hooks to retain the strips in place while the form is being handled and during the curing operation. The form is preferably made to a shape which will give the strips the proper curvature when the curing operation is finished and the hardened strips are removed from the forms; and these strips may be used lin the full lengths in which they are cured or they may be divided into desired lengths. 110
It is important, of course, that the forms should be sufciently strong, substantial and rigid to maintain their shape so that the strips will have the desired curvature corresponding to the curvature of the forms when the curing operation is nished and my invention provides such a form which is also light in Weight and capable of being easily handled. It is also important that the heated air should circulate between the strips during the curing operation and that the strips should be protected from the face plates which may get excessively hot, and this is accomplished with my invention by the provision of the reticulated fabric sheet Which forms an air space between the st ips and the face plate broken only by the strands of Wire forming the sheet and enabling the heated air to circulate between the strips and the sheet suiliciently to prevent ununiform curing of the strips.
I have shown the invention in a simple embodiment which has been found satisfactory in actual use but it may be desirable to change the form, construction, proportions and arrangenient of parts to adapt the form for other strips and for other material, or for other purposes, and reserve the right to make all such changes Within the scope of the following claims.
I claim:
1. A form for the purpose described comprising an elongated transversely curved face plate, a reticulated metal covering applied to the face plate to receive the material to be cured on the form, means adjustable transversely on the face plate for retaining the material in place on the face plate and including hooks on the form, and longitudinally extending retainer bars adapted to be supported by said hooks in engagement with the material to prevent dislodgment thereof from the form.
2. A form for the purpose described comprising a face plate adapted to support the strips of material to be cured on the form, means adjustable transversely on the face plate for retaining the strips of material in place on the face plate and including hooks on the form and longitudinally extending retainer bars adapted to be supported by said hooks in engagement with the strips oi material to prevent dislodgment thereof to retain the strips on the form.
3. form for the purpose described comprising an elongated transversely curved face plate adapted to receive and support the strips of maerial to ne cured, oppositely disposed hooks adjustable transversely on said face plate and projecting from the outer side thereof, and longitudinally extending retainer bars adapted to be supported by said hooks in operative engagement with the strips of material to retain the strips on the form.
4. A form for the purpose described comprising an elongated transversely curved face plate adapted to receive support the strips of material to he cured, said form having oppositely transverse slots, hoolrs on the outer face or" the form adiustably secured in said slots, and longitudinally extending retainer bars supported in said hooks in operative engagement with the strips of material to retain the strips on the form with the faces f ereof exposed.
5. A for the purpose described comprising an elongated transversely curved face plate adapted to receive and support the strips o material to be cured, oppositely disposed hooks adjustable transversely on said face plate and projecting from the outer side the-reci, and substanlel shaped longitudinally extending i: th the strips of material to retain the strips on the form with the faces thereof exposed.
6. A. form the purpose described comprising elongated transversely curved face plate adapted to receive support the strips of material to be cured, oppositely disposed spring hooks adjustable transversely on said face plate and projecting from the outer side thereof, sub'- stantially channel shaped longitudinally extending retainer bars having tubular inserts secured in the channels thereof to hear against the spring hooks t hereby the Webs oi said retainer bars will be heid in operative engagement with the strips of mate 'iai to retain them on the form with the faces thereof exposed.
