Patented Feb. 6, 1940 UNITED STATES PATENTT oFncs Application February 16, 1935, semi N ssie Renewed. February 14, 1939 11 Claims. or 13-55) My invention relates to a new and usei'u l-im provement in a templet, adapted for use as a. templet or guide on a profiling machine, which associated with a-cutting machine as used primarily in the automotive industry in conneotion with a type of machine known to the trade as Keller machines. In such machines it is customary to mount either the pattern or a re-- production of the pattern on the profiling machine in such a position that, the 'guide spindle may be moved over, thesurface of the pattern or the like. The movement of the guide spindle over the surface controls the movement of the cutter on the cutting machine so that the pat- 1 tern serves as a templet or guide which controls the operation .-of the cutter, whichis cutting into a casting or other suitable work piece from which a die is to be formed; 'It is customary, to
form the templet, to mount the pattern in positioh in a box built about six inches higher than the highest point of the pattern, and then fill the same withv plaster while in plastic condition and permit it to harden. There would thus.
be formed a block havinga female portion of 5 the die formed in one of its sides and this block would similarly be mounted in a suitable housing or enclosure which would be/filled with plastic or other suitable hardening material to form the male portion of the die. This is an expensive method of procedure and forms a templet of .considerable weight, with no provision for attaching to the profiling machine and not of sumcient strength due to the extremely heavy weight of the material and the lack of reinforcement.
Such a blockrequires about thirty-six hours to dry, while the present invention dries in a comparatively short time. Such a block is also very heavy, sometimes weighing a ton or more on the larger pieces, while the present invention 40 will reduce the weight to about one-fourth. It
is an object of the present invention to provide a templet of this class which will be inexpensive of manufacture'light and durable in use and easily strapped or clamped in position on the profiling machine.
Another object of the invention is the provision of a templet of this class formed from a comparatively thin layer of plastic material in a hardened condition and suitably reinforced.
I Another object of the invention is the provision of a templet of this class built up of a plurality of successive layers; of plastic material and layers of reinforcing materialsaturated with the plastic mate. 1
5 Another acct oi the invention is the pros vision-of a method ofconstruction whereby a inexpensively making a large number of reproductio'ns of a pattern of the section or part section as may be required instead of being, required to'use only the woodpattern.
Other objects willappearhereinafter. 15
Theinvention consists in the combination and arrangement of parts and the method'of construction hereinafter described and claimed.
The invention will be best understood by a reference to the accompanying drawing which 20 forms a part of this specification and in which:
Fig. 1 is a perspective view of a templet embodying the invention.
Fig. 2 is a sectional view taken on line 2-2 of Fig. l. 25
Fig. 3 is a fragmentary sectional view from the under surface with parts broken away showing, the construction of the female form,
Fig. 4 is a bottom plan view of the invention.
Fig. 5 is a perspective view of a reinforcing material used in the invention.
In the drawingI have illustrated the invention embodied on a templet of a vehicle fender.
In forming the templet the wood pattern would be mounted in a suitable rigid position. 35
l The templet illustrated in Fig. 1 is the male part and it would, of course, be necessary in fine plastic hardening material which forms a 45 stone-like face. This covering is preferably effected by rubbing the plastic material on to the surface with the hand so that all exposed parts will be covered and overlain with a layer of sub stantially uniform thickness,. about one-fourth 50 thickness. Materials 1 of fibrous material, such as are shown in Fig. 5, are then submerged in the plastic material and moved about therein, until the material becomes saturated or impregmated with a plastic material. On layer I where a heavy construction is provided. Super-- imposed on the layer i is a layer ll of plastic layers.
hardening material and the templet is built up of these alternate layers of reinforcing and plastering material. Each successive layer is permitted to slightly harden before the superim posed layer is placed thereon, but the hardening is not permitted to progress to such a degree as to prevent an intimate bonding ofthe successive When the outermost layers Ii and I2 are mounted in position, supporting legs l3 formed from plastic material and reinforced by the fibers M, are bonded thereto. These supporting legs serve as a means for receiving the screws or nails i5 whereby the device may be mounted on a supporting frame embodying the layers It and the crossbar-s I1. These legs also serve as supports for the plaster templet, holding it rigid and preventing warping. They also establish the specified angle at which the die and punch are to be set and seemingly the legs vary in length. The legs and frame combined provide an easy means of strapping or clamping the templet to the profiling machine.
In forming the male portion, the operation is the same excepting. that the female templet so formed is used instead of the pattern. The. surface 8, which is the guide surface for thecontact spindle, is formed of relatively hard material so that scratching or grooving by the guide spindle will not take place.
With the templet formed in this manner a minimum amount of plaster is used and a light -durable' structure is provided. Experience has shown that a templet so formed is much more rigid and durable than were it to be formed in a block without the reinforcement.
While I have illustrated and described the providing a stone-like surface, and a pluralityof spaced legs of plastic material bondedto the bottom surface of said body.
2. A profiling machine templet comprising a shell-like body having a plurality of alternate layers of hardened plastic material and reinforcing material, the outer face of said body formed of said hardened plastic material and providing a stone-like surface. and a plurality of spaced legs of reinforced plastic material bonded to the bottom surface of said body.
3. A profiling machine templet comprising a shell-like body having a plurality of alternate layers of hardenedplastic material and reinforcing material, the outer face of said body formed of said hardened plastic material and providing a stone-like surface, a plurality of spaced legs of reinforced material bonded to the bottom surface of said body, and a base secured to the lowermost portions of said legs.
. 4. The method of forming a profiling machine templet comprising taking a pattern or mold, covering a face thereof with a layer of grease, then with a thin layer of plastic material capable of setting, permitting same to partiallyset, then placing alternate layers of plastic material similar to the first mentioned plastic material and reinforcing material on said partially set layer while permitting partial setting of each layer of plastic material as placed, bonding spaced legs of plastic material thereto and permitting the plastic material tocompletely set, and finally securing a base to said legs.
5. A profiling machine templet of the classdescribed, comprising: a templet body having a contact surface formed thereon; a plurality of legs secured to and projecting outwardly from said body; means for connecting said legs together to provide a rigid formation; and attachment members carried by said connecting means and adapted for being attached to a supporting surface.
6. A profiling machine templet comprising a templet body having a contact surface on one side thereof; supporting legs secured to and projecting outwardly from the opposite side of said body; and a supporting frame attached to said supporting legs and fixed relatively to said body.
'7. A profiling machine templet comprising: a templet body having a contact surface on one side thereof; supporting legs secured to and projecting outwardly from another side of said body; and means mounted on the outer ends of said legs adapted for attachment to a supporting surface.
8. A profiling machine templet adapted for attachment to a. suitable support, comprising a templet body having a contact surface on one side thereof, and securing legs secured at one of their ends to said body and adapted for attachment to said support for securing said body mounted on and in spaced relation to the support.
9. A profiling machine templet adapted for attachment to a suitable support, comprising a templet body having a contact surface on one side thereof; and securingmeans carried by and projecting outwardly from another side of said body and adapted for attachment to said support for securing said body mounted on and in spaced relation to the support.
10. A profiling machine templet comprising a templet body having a working face on one side .and supporting legs carried. by said body.
