AUTOMOBILE TOP.

' Application filed March 22, 1920. SerialNo. 267,771.

This invention relates to the design and construction of a rigid, or non-collapsible, vehicle-top as a finished and complete article of manufacture, that may be subsequently used, either alone or in conjunction with other separately constructed elements, to form a cover for the vehicle body; and the general objects and purposes of our 1mprovements are to produce an article of this kind; which will be of'a substantially integral character, and will be easily handled as a unitary structure, both in the process of fabrication and in subsequent use; which will be light in weight and therefore readily manipulated in the various training, painting, covering, trii'nn'nng, finishing and packing operations to wh ch it subjected in passing through the different departments of the factory; which Wlll be sufficiently firm and unyielding in form to not only sustain itself, but also withstand any stresses or shocks it may receive either during the course of manufacture or in subsequent shipping and assembling operations; which will be capable of quick and convenient attachment to, or detachment from, the tonneau or main body of the vehicle, without the use of any loose fixtures that are liable to become misplaced or lost; 39 and which also possesses when in place on the vehicle body, a degree of inherent resiliency, and of elastic relationship to its support, that will enable it to yieldingly resist the severe torsional strain imposed upon the connected body and top members, and elastically absorb the violent shocks and jars to which they are subject when the car driven over rough roads or is turning corners at a high speed. The manner in which these various results are attained by the use of our improvements,and various other advantages that may be secured by such use-will be made clear to those skilled in this art, by the following description of the preferred form of organization which is illustrated in the accompanying drawings where:

Fig. l is a plan view-from below of the general if ame work of the structure. Fig. 2 is a corresponding plan view-from above --of the same organization. Fig. 3 is a side elevation of the completed top. Fig. is a longitudinal sectional view on the plane 4l-l of Fig. 2 lookingin the direction of the arrow. Fig. 5. is a partial horizontal section on the plane 55 of Fig. 4;;

Fig. 6 is a partial section on the plane 66 of Fig. 4. Fig. 7 is a perspective view of one of the important elements of our rigid unitary constructionf Fig. 8 is a sectional elevation on the plane 88 of Figs. 3' and a. Fig. 9 isa rear elevation of the top before the deck covering has been applied. Fig. 10 is a longitudinal section on the 'plane l010 of Figs. 1, 8 and 9. Fig. 11 is a partial horizontal section on the plane 11 11 of Fig. 9. Fig. 12- is a partial inside elevation (on an enlar ed scale) of the rear portion of the construction shown in Fig. 1-, and illustrates the manner of attaching the top unit to the tonneau and side units of an assembled closed body combination; F 13 is a plan viewfrom below,of those portions of the top and side units that are shown in Fig. 12, and Fig. 14 is a detail view of a modified form of one of the attachment fixtures illustrated in Figs. 12 and 13.

The skeleton frame of our improved organization is made of wood and comprises the curved lower sill 1; thevertical side and back posts 2, 2, 3, 3, and 7, 7; the upper deck rails orstringers 999-; the front bill board 9"; and the transverse arched roof struts 12, 12, 12, etc, all of which are mortised and tenoued (or scarfed and lapped) and then glued and screwed together, at their joints, so as "to form a substantially integral, unitary construction, that possesses per se, a high degree of stillness and rigidity of form. The upper deck portion of this L shaped framework is further strengthened and stiffened by the longitudinally arched sheathing strips 13, 13, 13, etc.,wl1ieh are securely fastened to each of the arched cross struts 12, 12, 12 etc, to form a flat dome shaped roof that will carry very heavy load stresses without collapsing or becoming permanently distorted.

The vertical leg portions of the frame work are all rigidly bound together by a continuous metal sheathing l lwhich entirely covers the exterior side and back surfaces of the structure except where it is cut away to form the rear window, \V, of the top; and at this point the edges of the sheathing are rolled inward and bent around the jointed sash members 7':', 77 ,--(as shown bent in Figs. 9 and 11)-so as to effectually prevent any racking or twisting of the window frame that might tend to break the glass pane. The lower edge, and

the two sideedges of this leg or foot of our unitary'top organization are further reinforced by T shaped metal rails or mouldings 15, 15..wl1ich overlap the adjacent edges of the metal sheathing 14; and which serve, not only as additional stiffening elements. but also as finishing and covering beads that overlap and conceal the jo'nits between the finished top unit and the complementary "body-and side units with which it is to be associated (see'Figs. 12 and 13) in the manner hereafter described.

Any rigid or non-collapsible structure, which hasthe general L shaped form that characterizes our unitary top organization,

is usually sensitive to any distortion stresses which tend to vary the angular relationship between the arms of the L, or which tend to rupture or loosen the framing connections at the juncture of these two arms. In order 'to efficiently resist the effects of'such strains on our improved construction we provide special means for reinforcing the joints ben an c'ur'edjto the corresponding face of a verticahside pas-t2. The rear arms of the bars 16 are carried around the curved side port'ionsof the upright part of the structure;

and the upper edge of the exterior sheath- 'ing, 14:, overlaps, and is securely'fastened to, the outer face of the overlying deck rails 9-4). The framework connections between the roof portion and the side portion of the complete top unit, are, therefore, rigidly bonded together by the over-lapping portions of the metal reinforcement elements 14-16 and 17 and the relative arrangement and disposition of the assembled parts are such that the interconnected deck and upright members constitute, as a whole, a cantilever suspension systemin which the parts 2-17 correspond to the pier supports thereforthat is exceedingly effective. and efficient in supporting'any load or external stress that may be imposed on the upper deck; and in also resisting any bending or torsional or twisting strains that may tend to distort the general .form ofthe complete structure and to thus rupture or loosen the connections between its individual elements.

The composite wood-metal construction above described constitutes a substantially integral unitary organization that is rela tively light in weight, but which is exceedfactory operations of; painting, covering,

ingly stiff and rigid incharacter and form, so that it may be readily handled as a selfsupport-ing unit in all of the subsequent finishing, trimming and upholstering the exterior and interior surfaces of the skeleton framework and thus producing the completed article of manufacture. The production of this light rigidly bonded unit combination of wood and metal members, as the base of the finished construction, is the fundamental, or initial, feature of our present improvements, and the subsequenttreatment to which this basic combination is subjected, in order to adapt it to use on various forms of body, may be varied widely, without essentially modifying the. character of the said improvements. The succeeding description of other detail features of construction which. are depicted in our accompany ing drawings, are, therefore tobe regarded asonly illustrative. of one exemplary embodiment of our complete invention.

In order to attach the'con'lpletcd top to an automobile 'hody'of the usual form, means mustbe provided for connecting the front :end of the deck with the upper portion of: the wind shield frame, and for supporting the lower edge of the top frame on the rear part of the tonneau body. In the construction herein illustrated, the first mentioned connection is provided for by attaching two socket plates 20-2U, to the under face of the front bill board 9" at points adjacent to the forward ends of the reinforcement plates 16-16; the parts being so arrangedv (as shownin Figs. 1 and (3) that the metal elements 16-20 overlap the joints between the side rails 9 and the front bill board 9" and thus serve to securely bind to gether and strongly reinforce the interconnected portions of these wooden members. The body supportfor the rear part of the top unit is provided for by attaching a pair of U shaped lugs 21, 21 to the bottom sill 1, at points adjacent to the juncture of that member with the uprights 2, fi -the said lugs being preferably so formed andattached to the members 1 and 2 as to overlap the joints between the latter and thus serve alsoas additional reinforcement means for these parts of the wooden framework (see Figs. 4;, 10, 12 and 13). The projecting cross legs of the U shaped. lugs 21 are slotted to engage with the upper ends of the support arms, 22-22, on the tonneau body B (Fig; 12); and may be flexibly coupled thereto by means of adjustable nuts 2323. An

additional attachment plate 24 is screwed to the lower part of each side post 2, for the purpose of receiving and supporting the end of a metal strip 25 that is secured to a side window panel C (see Figs. 12 and 13), when it is desired to form a completely closed, or partially closed, body organizatill bonded together into an integral unitary and substantially rigid skeletonand the latter has been additionally reinforced by the special attachment fixtures required to con nect it to other parts ofthe vehicle bodythe said skeleton unit is completed and converted into a finished individual article of manufacture by covering the exterior of the roof sheathing 13 (and the adjacent exposed edges of the deck elements 9-99 with a suitable waterproof fabric; and lining the interior surfaces of the framework with tapestry or leather, or such other upholstering material as may be desired; and in the construction illust 'ated in the drawings we have made special provision for the attache ment of a large dome light to a central portion, 26, of the roof structure. Other side lighting fixtures may be attached, as desired, to the uprights 3-3 or 77, and the'bases of all these fixtures as well as the switch connections therefor-are covered and concealed by the interior linings of the completed top.

In order to avoid undue complexity in the drawings-and in order to more clearly show the character of the skeleton framework of our improved construction-the inner upholstery covering has been omitted from all the accompanying illustrations except those of Figs. 12 and 13; but the general manner in which this lining is applied and attached to the unitary top structure will be readily understood by those skilled in the art, without further description. In our new article of manufacture we preferably provide this lining 27, with. a depending skirt 28 that is adapted to extend down over the joint between the top unit A and the body unit B, and to be buttoned or secured to the bacr seat cushions and in the inner lining of the tonneau by means of glove or curtain fasteners 29, 29, (or by any other suitable means), when the said units are as sembled. This depending skirt also covers and conceals the attachment fixtures, 21, 222,

of the connected units; and for the purpose of preventing wear and in order to avoid wrinkling and creasing, the portions of the skirt that overlie the projecting parts of the coupling elements may be reinforced by an additional thickness of leather or other suitable material, as shown in the lower edge view of Fig. 13. This reinforcement flap may be stitched or otherwise secured to the main lining 27 on either the interior or exterior surface of the latter; and may be so arranged as to cover only the fixtures 212223, or to cover both these fixtures and the auxiliary side panel attachment 24 as Well. i In order to cover that portion of the top framework that. is beneath the loose portion of the skirt 28, we preferably provide a supplemental lining strip 30 which is permanently secured to the inner faces. of the lower sill l and the adjacent portion of the front posts'2-2,'and serves to conceal the unfinished surfaces of those parts when the skirt is lifted to secure access to the attachment fixtures 212223 and 24.

Instead of forming the straight portionof the lining as an integral part of the interior covering, we may, if desired, make this skirt as a separate portion that is attached at both its'upper and lower edges to the adjacent portions of the linings of the top and tonneau members of the ve hicle. In such a case the skirt is made relatively narrow; being only of such width as is necessary to properly cover and conceal the attachment fixtures between the upper and lower units. This separate skirt may be furnished as a part of our completed article of manufacture-in which case it constitutes a part of the entire combination-or it may be furnished as a separate piece that can be attached at any time to the parts with which it is associated, suitable provision being made in such case for the proper fastening devices on the top and body linings.

Our improved unitary top construction is also preferably provided, at suitable points in the deck lining, with recessed pockets formed between the skeleton framework and the inner upholstery covering thereforfor the reception of flexible weather curtains that may be readily unfolded and applied to the connected body and top units, for the purpose of closing the open sides of the assembled organization. We have not deemed it necessary to illustrate and describe,,in detail, the form and arrangement of these curtain pockets, for the reason that this feature of construction has been made the subject of a separate application for Letters Patent, Serial No. 158,455, by one of the applicants herein; and it does not constitute a part of our present joint invention. l Ve have also omitted all description of various minor or auxiliary features of COnS'tIl!C'lZlO1i--Stl(l1 as the provision of window shades for the rear window the provision of weather guards or water gutters along the edge of the deck member, etc.,on the understanding that these, or other, special fittings, can be provided, as required, by thos srilled in this art. i

It will be readily recognized that many of the specific details of the organization, which we have hereinbefore illustrated and described as one embodiment of our present improvements, may be varied, as required to meet special conditions of manufacture or use, without departing: from the spirit of our invention, or without sacrificing any of the characteristic advantages to be attained thereby. Foreztample: Instead of using the form and arrangement of attachment of fixtures indicatedby the reference characters -21.-Q2-23 in Figs. 1 to 13, we may, in certain-cases, use an invert ot' thisgtixture ar rangement such as is shown in Fig. 14; in which the female socket member 21 is socured to the tonneau framework, and the male threaded member 22 is screwed to the adjoining portions of the wooden members 1 and 2. One advantage-oi? this alternate arrangement of parts is that the socket plate 21 may be inset in the tonneau framework and covered by a detachable flap of the tonneau lining. thus reducing the bulge" or projection of those parts of the skirt 28 that overlie these main attachment fixtures.

The many important advantages of our invention-as exemplified in a complete tinished unitary article of manufacture such as has been hereinbeforedescribed-will now be readily understood and appreciated by engineers and others who are familiar with the problems involved in vchiclebody construction. Some ofthe more important tratures and advantages of our improved unitary top structure may be briefly summarized as follows: f

I. It presents the combination of an interbonded wooden framework and a system of longitudinal and transverse metal reinl'orccments, which are rigidly secured to the principal horizontal and vertical members of the said frame. and which are so ft'ormcd and arranged as to both individually and mutually overlapthe joints, or other per tions, of the wooden base that are subjected to the maximum load stresses. e thus obtain a substantially integral skeleton top construction which is relatively lightbecause the majorportion of it is .wood-and which is also very rigid and unyielding in form because it is securely braced and still"- ened and reinforced by metal elements so designed and disposed as to most eilcctually resist thebending and twisting strains that would tend to rack and warp, and ultimately loosen and distort, the inter-joined wooden members of the organization.

11. The general structural character ot" our new top-and the relative disposition of the wood and metal elements therein-As such that the composite skeleton framework constitutes in form and effect, a cantilever support system, in whichthe main wooden members are under compression and the principal metal reinforcements are under tension each set of members being thus utilized to carrythe elastic strains to which they otter the mosteftective resistance.

III. l he combination of lightness and rigidity of form, which we secure in the above described manner, makes it possible to readily manipulate the self sustaining skeleton top framework-and turn 1t on its 'expedites the progress of the work in each departn'ientsparticularly in upholstering the interior surfaces of theunit-thcrchy increasing the outputand reducing the labor cost of manufacture.

IV. The self contained integral character of our finished article of manutactm'e permits of the storage and shipment of these tops as complete interchangeahle stock units; and the L shaped form of the units also enables them to be packed in ncsts' thereby greatly increasing the number of tops that may be placed in a given warehouse or box car space. This ell'ects a further important saving in storage and shipping charges.

V. The metal reinforcement and attaclv meat elements, at the base, or lower sill, portion of our improved top structure. are so designed and arranged that. when the top is assembled in position on the tonneau of has, in itself, peculiar advantages, in that it possesses great rigidity for a given weight of metal-and therefore constitutes a very eilective reinforcement for the lower sill and side post members of the combination-and also because it can be attached to its:- assembled parts by means of conccalml r re in passing through the flange portion of the T rail section, and when so attached it constitutes an artistic and close lilting element of the external surface finish. and one that cannot be accidentally separated or detached therefrom by the various stresses and strains to which the article is subjected.

VII. The connective or coupling fixtures, which we provide for flexibly at'tar hing our complete unitary top member of the. vehicle are so positioned that the main points of support for the integral top unit are only a short distance from the transverse plane through the center of gravit Y thereof; and are substantially in line Wltll the pier points of the cantilever support system of the structure. The rigid integral top is, therefore, to a certain extent, balanced on the most rigid and unyielding part of support-i. e. on. the rear portion of thetonneau frame,and is free to yield, as a whole, with respect to the lower portion of the body.

VIII. The open flexible character of the coupling connections, between our substantially rigid integral top and its body support, permits the two assembled units to move slightly with respect to each other, and to thus resiliently readjust themselves to varying stress and strain conditions without any permanent distortion of either unit. This resiliency of support protects our rigid top against the effects of severe twisting or buckling strains or of violent jars and shocks to which the body of the vehicle maybe subjected in traveling over rough roads, or in turning corners at high speeds, etc ;the majorportion of these effects being afi'ective ly cushioned and absorbed by the elastic yielding of the aforesaid flexible'connectivc fixtures. This feature of our improved construction is of marked importance; not only because it reduces the chances of injury to the to a, but also because it tends to check the sic e sway and pitching of the lower part of the vehicle body, and thereby supplements the action of the spring suspension system in stabilizing the movement of the tonneau and in enhancing the comfort and safety of the occupants of the car.

IX. The light and self-supporting nature of our new rigid top and the means which we provide for flexibly attaching it to the car at four points only, makes it very easy to connect or disconnect the said topas occasion may require-without the aid of skilled labor and without the use of any special appliances or the attachment or detachment of extraneous loose parts; and.

when the upper unit is removed from the car it may be stowed away as a self-contained entirety that does not require any large amount of space or any particular protection against such rough handling as might injure the deck covering or the collapsible tripod supports of an ordinary cape or canopy top; and when our improved top has been removed from the body of the car the latter does not'present any protruding fixtures which detract from the external finish of the tonneau unit or which might tend to catch or tearthe clothingof the users of the car when they are entering or alighting from the vehicle.

With the foregoing disclosure as a guide it will be possible for those skilled in this art to vary the construction herein described so as to utilize our improvements in many different forms of rigid unitary top organizations, and we havenot therefore considered it necessary to illustrate more than one complete exemplary embodiment of our invention. We do not therefore limit ourselves to the specific details of structure that have been heretofore set forth as generally characteristic of our present developments. But what we claim is:
