COT FOB INVALIDS.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed August 28, 1913. Serial No. 787,113.

To all whom it may concern;

Be it known that I, Jnssn H. Kmnnion, a resident of Valley Center, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Cots for Invalids; and I do hereby de-i clare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to adjustable cot for. invalids and cripples, and has for its object to provide a cot that can be adjusted to suit various conditions and is more especially adapted to persons having a broken leg, who, during their confinement have to be continuously in one position, until the bones knit together.

One of the objects of my invention is to provide a means whereby the patients leg can be placed in various positions and still be kept in proper condition to allow the said bones to properly unite.

I attain these objects by the means illustrated in the accompanying drawings, described in the specification and the appended claims.

Referring to the drawings, Figure 1 is a perspective view of my device. Fig. 2, an end View, and Fig. 3, a plan view in. part of Fig. 1, showing a reticulate fabric positioned on the top section of my device, on which rests the patient, said fabric not being shown on Fig. 1, in order to more fully disclose the mechanism thereof.

Similar numerals designate similar parts throughout the several views.

My device is substantially in two sections, 1 and 2, and is of a height preferably to bring it when in a normal position on a plane with the bottom of a chair but can be used under the patients leg when in bed and is substantially of a size to receive the patients entire body; section 2 being positioned above section 1. Said sections are transversely and longitudinally adjustable. Said sections are composed of sub-sections 3-3-3-3, are slidably connected together by means of keepers 4 aiiixed thereto by -ivets 7 a plurality of holes 5 are made in said members so they can be adjusted to any desired position and rigidly aflixed by bolts 6. It is obvious the structure can be lengthened or narrowed as desired. A portion of the lower section is flattened down as at 1'7, a feature that will be referred to later.

similar wheel 26 defined in To the lower section is pivotally affixed as at 12 and 34, upwardly extending arms 8 and 9 and on the arm 8 are cogs 35. The arms 9 are in two sections and are pivotally connected together asat 10 and can be made rigid by placing bolts in the holes 11. One end of section 2 ispivotally connected to the top ends of the arms 9 as at 12 and the opposite end of said section is made to swing up and down by means of a geared mechanism. An arbor 23 is journaled in the upper section and has afiiXed thereon a pair of spur-wheels 24, which engage the cogs 35; lugs 38 aiiixed to the adjacent bars, hold the arms in contact with the spurwheels 24. On the end of said arbor is placed a bevel wheel 26 which engages a on an arbor 25 which extends along the sections 3, being journaled in bearings 27 welded to said sections (a piece thereof being removed to show the connectionof said section) and has aflixed thereon a thumb-knob 28. It is obvious that when the knob 28 is turned, the free end of the upper section will be moved up and down on the arms 8 until it reaches a horizontal position indicated by the dotted lines 16 in which position said sectionwould be on a plane with the bottom of a chair and held in that position by apin 29, passed through the arbor 25, which contacts the adjacent bar, and by means of the braces 13 and the bolts 1414, the upper section can be made rigid in its upper or lower position.

If the patient is required to lie on his back in bed and it is desired to elevate his leg a certain distance, it can be accomplished by removing the bolts 11-11 and the arms 99 can be moved down as indicated by the dotted lines 3636 until the top section would be in the position indicated by the dotted lines 1515, bringing the end of the top section down on the end of the flat portion 27 of the lower section. If the patient wanted to sit on a chair, the device would be put in the position as shown in Fig. 1, which would let the foot down near the floor.

Over the entire section 2, I stretch a reticulated fabric 22, on which rests the pa tient, which is held in proper position when fastened to a series of pins 21 in the top section and when an adjustment is made in the length or width of said section, the said fabric can correspondingly be ad usted on the pins 21. To the free end of section 2,

proper size, will prevent muscular contracr.

tion and allow a broken bone to properly knit together and thereby prevent shortening of the leg. I I

Then the patient is too heavy on the fabric 22, it tends to draw the sides of the.

top section together; This I prevent by placing a curved brace 18 therebetween and aflixed thereto with bolts 2020. Said brace is provided with a plurality of holes and is adjustably held together with a bolt 19.

Having described the construction and assembling of my device, what I claim is' 1. In a cot for invalids substantially in two sections, each section beingcomposed of a plu ra-lity of sub-sections, means for, adjusting said sections whereby the cot may be expanded or contracted, arms in two sections pivotally connecting the first named sections together, means to make said arms rigid, and a brace to make said arms rigid with the lower section, armsh'aving cogs thereon pivotally connected to the lower section, an arbor journaled transversely in the upper section, spur-wheels mounted upon said arbor to engage the cogs on the aforesaid arms, and means for rotating said spur-wheels to position the free end of the upper section in any desired position and means to hold the cogs on the said arm incontact with thespurwheels. v 1 2. In a cot for invalids substantially in two sections, each section being composed of a plurality of sub-sections, means for adjusting said sections whereby the cot may be expanded or contracted, arms in two sec-' tions pivotally connecting the first; named sections together, means to make said arms rigid, and a brace to make said arms rigid with the lower section, arms having cogs thereon pivotally connected to the lower secsection in any desired position and means to hold the cogs on the said arm in contact with the spur-wheels, a sheave affixed to the free end of the upper section and a rope to play over said sheave, a weight aflixed to said rope.

3. In a cot for invalids substantially in two sections, each section being composed of a plurality of sub-sections, means for adjusting said sections whereby the cot may be expanded or contracted, arms in two sections pivotally connecting the first named sections together, means to make said arms rigid, and a brace to make said arms rigid with the lower section, arms having cogs thereon pivotally connected to the an arbor journaled transversely in the upper section, spur-wheels mounted upon said arbor to engage the cogs on the aforesaid arms, and means for rotating said spur wheels to position the free end of the upper section in anydesired position and. means to hold the cogs on the said arm in contact with the spur-wheels, a sheave affixed to the free end of the upper section and a rope to play over said sheave, a weight aflix'ed to said rope,a reticulated fabric stretched over the top section, and means for adjustably it to said section, and means for preventing said section from contracting when weigl'it is applied to the fabric.
