KENNETH 'n "cnILns, or nn'raorr, MICHIGA AUTOMOBILE BODY CONSTRUCTION.

Application filed November 17, 1'922. serial no. 601,486.

To all whom it may concern;

Be it known that I, KENNETH L. Crmms, a citizen of the UnitedxStates, residing at Hotel Stevenson, 46 Davenport, Detroit, in

the county. of Wayneand State of Michigan, have invented certain newand useful Improvements in Automobile Body Con-- struction of which the following is a specification. g g I This invention relates to automobile or carriageconstruction and has for its object an improvedbody materialfor this purpose. I

- Heretofore it. hasbeen customary to construct the body of automobiles .from alum'1- mum and sheet steel. The aluminum is r elatively expensive and easily bent and marred after painting. Sheet steel bodies are open to numerous objections such .as l-relatively heaviness andliability .to bend andmart;

Istru'ction, although it is possible of course to use'ametal frame. Tothe wooden frameis I secured, by fstaples or otherwise, a heavy wire mesh alwhich in a large measure takes when painted. Furthermore, the sheet bodies easily rust under the paintjandeause a great dealof trouble inpreserving the finish I The invention relates more particailarlya body-construction includinga. skeleton frame and an exteriorwall secured: thereto. 7 According to. a feature of the invention,

the exterior wall, which j is" secured to the.

skeleton frame, comprises a slightl flexible and yieldable foundation with a ayer of flexible finishing fabric over the foundation,

with an exterior finishing surface.

the term finishing fabric? bein herein used as defining any yieldable plia le material such as cloth or leather capable of bein' stretched over the foundation and provide A further feature of the inventlon includes the use of a non-rigid or pliable ma terial-to afford a smooth support'forlthe flexible finishing fabric. y The use of a skeleton frame witha slight- 1y flexible and yieldable foundation such for instance as a strong wire mesh. produces a body without the objectionable rigidprior constructions, the body being more elastic. and flexible than an all'meta l body and yet having sufiicien't rigidity to stron tortion or buckling. Also the wall of ,a

body constructed this manner is sound, deadening and heat insulating and them-- tire body is practically noiseless being substantially free from rumble, vibration, or rattle.

.yieldahl'e, flexible and. which The non-rigid or pliable material not-only alfordsasmoothl support for the flexible Fig. 2 is a section "taken througha portion of the back of the body.

Fig. 3 is an enlarged detail showing the body material.

I The present invention permits the construction of the body below the belt moulding as well as above, of a material which is durability'offinish. I,

I employ preferably a wooden frame com (the 'placeyof the metal panels used in the has a great preferably two to the square inch. Metal panelsinot only provide a cover and finish but also brace the frame construction and "bear part of the strain. -Hence-this foundation wire 'forms a fair, and a lighter equivalent, of metal in connecting together the frame members and giving the whole a rigid construction. Furthermore, the foundation wire serves as arelatively strong yet slightly flexibleand yieldable support for the layers of material laid thereover. I

' The first layer of material superimposed on the wire mesh foundation is a layerof cottonwa.dding b;,over this is laid' a hard andstrong fabric material, such as buckram.

Three layers ofbuckram are, preferably, laid over the wadding. These are .designated 0 in the drawings; over the buckram is laid-'a' high grade finishing'cloth designated eiiI find the most suitable material a for, this pur o'se is a material known on the market as'll eritas leather cloth. Thi is unusually Well adapted for the.- urpose ,Ihave in view. In a general: wayjii' will}; describe theldesirable characteristicjs zqf the finishing fabric. It should be a-lr'i'gh grade fabric'impregnated withia material such as varnish, or some of the y'ro'xylin compound. 'Meritas leather clo 1 is preferable to cloth impregnated with pyroxylin compounds as this ,takes varnish to much better advantage.

evident that the body material above explained has many characteristics .sup

.prevent the blow- 2o vring, scratching or injuring the body.

rior-to the ordinary .metal body panel. In the firstplace it does-not mar nor dent under the ordinary stresses but both the superimposed layers and the foundation material have a capacity for flexing and distorting. within j ap ropriate limits which om permanently m Iahn' fir'rishmay be easily renewed and inexpensively,; by varnishing at long periods. In case the finish is injured it may be readily removedaby simply taking out assectionof the layers or acomplete secsupjerimpo'sed tion 0 .the com site'material. All: that 1s necessary to e ect this, is to take ofl' the moulding and disengage the material from its fastenin 'W anamsa 1r 1.
