Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed October 23, 1915. Serial No. 57,492.

To all :whom it may concern:

Be 1t known that l, ALBERT G. MITCHUM, a citizen of the United States, residing at Davenport, in the county of Lincoln and The object is to provide a device of this 'character which can be easily and quickly secured in operative position in an automobile, and which can as easily be removed and folded into a small, short,compact package when not inuse, so that it can be conveniently carried in the machine, occupying but little room.

Further specific objects will appear in the 'subjoined description.

The invention consists in certain novel combinations and arrangements of parts hereinafter described and claimed, reference being had to the accompanying drawings which form a part of this application, and in which- Figure 1 is a perspective view of my device in operative position in an automobile, the side curtains of the automobile being omitted for the sake of'clearness. Fig. 2

is a plan view of the device, showing the slats arranged in operative position. Fig. 3

is a plan view of the device partly folded. Fig. 4 shows the device folded and rolled up. Fig. 5 shows the stifiening rod used at the end of the device not provided with f slats; and, Fig. 6 is a perspective of one of,

the metal angles used on the longitudinal slats. Fig. 7 is a broken perspective showing modified means for connecting the free ends of the transverse slats 3 and 4 with the free ends. of the parallel slats ,2 and 2". Fig. 8 is a broken plan view showingone of the transverse slats riding up laterally ove the spring 21 and approaching parallelism with the longitudinal slat 2*. Fig. 9 is a vertical section of the construction shown in Fig. 7 and, Fig. 10 is a perspective on an enlarged scale showing the corner connections illustrated in Fig. 7 in operative relation to each other, with the slats removed.

Referring to the. specific construction of my invention, the numeral 1 indicates the main or body portion or the device, which portion is formed of a single piece of strong flexible material, usually a piece of fabric of some kind, such as heavy canvas or duck.

At one end, this body portion is provided with a series of longitudinally disposed slats 2, equidistant from each other. These slats are riveted or otherwise suitably secured to the main body portion of the device, and their length is preferably equal to the width of the bed bottonr At the ends of the series of longitudinal slats 2, are two slats 3.and 4: extending at right angles to the slats 2 when the device is in operative position. slats 3 and 4 are pivoted to the device at diagonally opposite corners of the slatted portion thereof, by the pivots 5 and 6 respectively; while at their other ends they are adapted to be engaged and held in operative position by removable bolts-7 and 8, which are of course also at diagonally opposite corners of the device. The pivots 5 and These transverse 6 and the bolts 7 and S, at the ends of the transverse slats 3 and 4, extend on through the ends of the

outer ones

2 and 2 of the series of longitudinal slats 2. From this construction it will be seen that when the bolt 7 is removed, the bar 3 can be swung on its pivot 5 and brought into parallelism with the longitudinal slat 2*, as indicated by the arrows leading from 7 to 8, the two bars lying in flat engagement with each other when in this position. In like mannor, the transverse slat 4 can be brought into parallel fiat engagement with the outer one 2 of the series of longitudinal slats as indicated by the arrows leading from 8 to 7.

At the forward end of the main or body portion 1 of my device I providethe transverse loop 9 extending across said end, which loop is formed by turning the end of the fabric back uponitself a short distance and then stitching the two lapping sections together. The loop thus formed is made large enough to receive a'substantial rod 10 which is inserted therein to-stifien the forward end of the section 1' when the device is in operative position'on the automobile.

Just to the rear of the loop 9 I provide two openings 11 in the section 1 to receive the two buckle-straps 12'; While at the rear end of the device, at its corners, the straps 13 are securely attached by riveting or oththe device serve to engage suitabie parts of the automobile at the front and rear ends thereof to hold the device securely in operative position when in use.

The small angles 14 are secured to certain intermediate ones of the longitudinal slats 2 near the ends of said slats to form abutments or stops for the transverse slats 3 and 4 between their ends, when they are brought to their operative position.

The slats 3' and are of the the longitudinal slats d'hen the device is in operative position on the automobile, the rear end of the slatted section rests on the back of the rear seat, and the iront end of the same rests on the back of the front seat, while the forward portion of the bed-bottom not provided with slats extends on from the back of the front toward the forward end of the automobile. This latter part of the device, which sup ports tlie feet of the occupants of the bed is held suitably tauttransversely by the slat it at the rear end of said portion and the rod 10 at the front end thereof.

In operating the device, when it is desired to fold up the same, automobile by means of the front and end buckle straps 12 and 13 respectively; then the rod 10 is withdrawn from the end loop 9; the bolts 7 and Sare taken from the ends of the slats 3 and 4, and said slats are swung on their pivots 5 and (3 into'parallel engage ment with the outer

longitudinal slats

2 and 2 into the position shown in Fig. 3; the forward end of the device is then lapped bacluvardly over the slatted end thereof as also shown in Fig. 3, and the device is then ready to be rolled up into a compact roll as illustrated in Fig. 4, the rod 10, of course, being inclosed in the roll. The roll thus formed is then tied at each end with suitable cords 15; or thestraps 12 may be rcinoved from the eyes 11 and used for that purpose if desired. The device can then be laid in the automobile or secured to the running board where it will take up very little room till it is again needed for use.

Of course. the transverse slats 3 and 4 may be dispensed with if desired, and the device Will still render cllicient service, since in that case the ends of the longitudinal slats would still be well supported anyhow on the backs of the front and rear seats of the automobile, and would be held transversely taut thereon by means of the straps at thc corners of the device.

Should it at any time be more desirable to reinforce the outer ones 2" and 2 ol the series of longitudinal slats :3 than to havc the transverse slats at their ends, said trans verse slats 3 and 4 may be swung on their pivots 5 and 6 into-parallel flat cngagcinont Withsaid slats 2 and '2" respectively into the position they are ordinarily brought to same length as it is loosed i'rom the occupy when the-device isready to be rolled up, and since the transverse slats are of the same length as the longitudinal slats, the opening for the bolt 7 in the transverse slat 3 will be brought into registration with the opening for the bolt 8 in the slat 2 while the opening for thebolt 8 in the transverse slat will be in registration. with the opening for the bolt 7 in the slat 2 Then by simply passing the bolts 7 and .8 through these registering openings, the slats 3 and v at are securely fastened in parallelism with the

slats

2 and 2* thereby doubling the which is a metallic plate 16 struck up at one side to form the right-angled section 17, and at an adjacent side struck up to form an angular section composed oi the vertical portion ld'terminating at its top in the inwardly bent horizontal portion 19. Each plate 161s provided with suitable openings 20 for securing the plates to the free ends of the

slats

2 and 2 with the upturned sections 17 of the plates at the ends of the slats, and the sections 18 at the outer sides thereof.

The section 18 is of the same heig tas the section 17, so that at its outer enithe horizontal section 1.) overlap' and rests on the top edge of thesection ii.

Cooperating with each of the plates 16 isa spring 21 having openings at its rear end for securing the spring in operative position relative to the plate 16, as clearly shown in Figs. 7 and .F'oin these figures it will be seen that the to ward end of the spring is bent to rise upwardly above the plane occupied by the rear end thereof where it is scoured to the slat 2. At its forward frce end the spring terminates in the downwardly bent section 23 which takes into an opening 2-1 in the slat 2 just at'the rear of the plate l6 to permit the upwardly in clined. forward end of the spring to be depressed.

Referring further to Fig. 7, it will be seen that when the free end ot' the transverse slat l is swung to and the l'rco cud oi the parallel slat .l", the end of the slat i will ride up on the spring 21. and that downward pressure applied to tho slat 4- will depress the spring 21 and permit the end of the slat r to pass inidcrncath the section if) of the plate till said slat abuts against the vertical end section 1'? ol' the plate, at which time the i means; a

forward end of the spring 21 is released and flies up at the rear side of the slat i to lock said slat in the position it has just assumed.

The downwardly extending end-section- 23 of the spring could be dispensed with, in which case there would be no need of the opening 24 which receives it when the spring is depressed but it will be seen that this end "23 of the spring acts as a bolt projecting into the opening 24, so that unless the spring were depressed, the end of the slat t would have to shear this bolt before the slat could be withdrawn from its locked position. When it is desired to bring the transverse slats 3 and 4 into parallelism with the slats 2*- and 2, to which they are respectively pivoted at one end, (as for instance when it is desired to fold up the bed bottom), the modification I have shown meets the requirements admirably, since the free ends of the end slats 3 and 4 are received under the horizontal sections 19 of the corner plates 16; and in order that these slats may be the more easily entered underneath said sections 19, the tops of-the free ends of the springs 21 are transversely inclined inward to provide an inclined surface on top of the springs for said end slats to ride up over. This arrangement also causes the upper outer side of the free end of the spring to present sharp corner to the under side of the slat which depresses the spring. This sharp corner extends in the direction of the 86 grain of the slat, so that it easily engages the slat and holds it against movement away from the plate 16.

Fig. 8 of the drawings shows the slat 3 riding up over the spring 21, almost ready 40 to be depressed and passed under the sec tion 19 01 the corner plate.

Having thus described the principles em bodied in my invention, and having shown and described means for making a practical 46 application of the same, what I claim as new and desire to secure by Letters Patent 1s:-
