GYVE.

Application filed February 17, 1913.

To all @07mm it may concern Be it known that I, Frmnnicii C. NAGLE, a citizen of the United States, residing at Keithville, in the parish of Caddo and State of Louisiana, have invented a new and useful Gyve, of which the following is a specification.

rthe present invention appertains to gyves and is particularly an improvement over the gyve disclosed in my forme-r Patent Number 941,942 issued November 30, 1909.

t is the object of the present invention to provide a fetter or gyve applicable to the limbs of the human body which shall be operable to ordinarily permit free movement of the members of the limb Within certain limits, but which shall lock the members of the limb when such limit is passed. In other words, the present invention aims to pro vide a device of the character indicated attachable te the arm or leg of a person so as to ordinarily permit the limited use of the arm or leg, such for instance, as in walking, but which shall lock the arm or leg should the wearer attempt to run, strike another person or the like.

rthe present invention is especially designed for use on prisoners, maniacs or other persons under commitment, in order that they may ordinarily be permitted to have limited locomotor movements, and in order to prevent them from running or from using their limbs otherwise, beyond certain limits rihe invention is also adapted for locking the limbs in such position that they may not be employed until released er liberated by means of a key.

This invention also aims to provide a device of the character indicated of novel and improved construction which shall possess a high degree of utility, reliability and etti ciency.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in 'the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying Specification of Letters Patent.

drawing, wherein similar reference characters have been employed to denote corresponding parts and wherein Figure l is an illustration of a human body provided with the gyves. Fig. 2 is a frag mental face view of the gyve or of the lock proper for the joint of the limb. Fig. 3 is a view of the device illustrated in Fig. 2 showing the near face cut away. Fig. 11i is a sectional view taken on the line .t-ll of Fig. 3. Fig. 5 is a perspective view of one of the teeth of the dogs or pawls.

ln carrying out the present invention, reference being had to th accompanying drawing, there is provided a novel form of lock designated by the numeral G which is adapted to be disposed at the joint of the limb, and which may be conveniently termed or denominated the joint lock or limb lock. its illustrated in l, the lock (S is disposed at the knee joint of the lower limb, and has the sections 7 and 8 secured to the respective parts thereof, the parts of the casing of the lock being adapted to rotate. rThe section 7 is adapted to extend along the thigh or femur bone of the wearer while the section 8 is adapted to extend along the lower limb proper' or the calf to the ankle. A section 9 is pivoted to the upper end of the section 7 and is adapted to extend along the hip of the wearer or above the waist line. Fig. l also illustrates a lock G applied to the elbow of the arm, and having the respective sections 7 and S attached to the parts of the casing of the lock. rl`he section 7 is adapted to extend along the upper section or humerus, while the section 8 is adapted to extend along the forearm to the wrist.

From the foregoing, it will be manifest, without further explanation, that the present appliance may be attached to either the upper or lower limbs with equal propriety, and it will therefore only be necessary to describe one of the locks in detail, the two locks being precisely the same, with the exception of the respective sections attached to the parts of the casing of the lock which must be of suitable length to accommodate the upper and lower limbs, as will be apparent.

Upon the respective sections S. 7, 9. 8 and 7, there are adjustably mounted the locts l0, 10b, 10C, 10d, and 10e, and to the locks are CIN attached the respective ends of chains or flexible members 11, 11b, 11C, 11d and 11e. rllhese locks iorm the subject matter of a co pending application, Serial Number 749,002, filed Feb. 17, 1913, and need not be described or illustrated in detail in the present application. rThe locks 10, 10b, 10, 10d and 10 are adjustably mounted on the respective sections and are designed to lock at various adjusted positions on the sections as well as locking the free ends of the chains or flexible members. These chains or flexible members are preferably covered with rubber tubing or the like, so as to protect the wearer from being chafed or otherwise injured. rihus, the chains or bands 11, 11b, and 11C are adapted to encompass the ankle, the lower portion of the thigh, and the wrist, respectively, so as to hold the sections 7, S and 9 in operative position, the said sections being capable of swinging movements to permit the movement of the lower limb. In a like manner, chains or bands 11d and 11e are adapted to encompass the wrist and liumerus, respectively, so that the respective sections will move with the members of the arm. The locks 10, 10b, 10C, 10(1 and 10e are adjustably mounted on the respective sections as above indicated, in order that the chains or flexible members may be properly positioned to most effectively hold the gyves in position upon the limbs.

Coming specifically to the joint or limb lock, the same embodies a casing comprising two rotatable parts, or an inner cap 12 and an outer cap 13 telescoping thereover. The respective sections 8 and 7 have their ends riveted or otherwise secured to the faces of the parts 12 and 13 of the casing, in order that when the sections are swung relative to each other, the parts of the casing will be rotated upon each other.

TWithin the part or cap 12 there is fitted a ring or annulus 14, the saine fitting snugly within the flange or rim of the part 12. T he flange of the part 12 is undercut slightly, as seen in Fig. 1, and the periphery of the ring 1e is slightly beveled to lit within the under` cut portion so as to retain the ring into position, and the ring is also preferably constructed of four sections or is split at points throughout its length. The ring 14 or two diametrical opposed sections thereof, are each provided with a series of ratchet teeth 15, which face in the proper direction in order that the lock will operate in manner hereinafter described.

A guide 16 is disposed concentrically within or between the parts of the casing, the same being circular at one side and fitting within an opening 1'? provided in the part 12. An annular rabbet 18 is provided around the opening 17, in which is seated a disk or plate 19. A pair of rivets or securing members 2O are passed through the disk 19, guide 16 and the face or part 18 of the casing, in order to secure the parts or faces of the casing together and in order to secure the guide 16 to the face or part 13 of the case.

The guide 16 is provided with the parallel edges 21 within the casing, and a pair of oppositely disposed U-shaped pawls or dogs have their arms straddling the guide 16 and working' snugly against the edges 21 so that the pawls or dogs are constrained to slide radially or on a diainetrical line. Each of the pawls or dogs 22 is preferably stamped from sheetmetal and embodies a long arm and a short arm, the long and short arms of one pawl overlapping the short and long arms of the other pawl. A leaf spring' 23 is secured to each pawl 22 adjoining the butt end of the long arm and has its free end bearino` against the free end of the long arm of the other pawl, the springs 23 tending to separate or spread the pawls so as to force them into engagement with the ring 14. Each of the pawls 22 is also provided with a tooth 24 at its intermediate point, the teeth 24e having dovetailed projection 25 engaging the pawls. T he pawls are of a combined thickness so as to i'it snugly between the faces of the casing and the teeth 2li are also of a thickness to work snugly within the faces of the casing, while the dovetailed projections 25 are approximately flush with the faces of the re spective pawls.

The guide 16 is provided between the rivets 2O with a lateral recess 26 for the reception of a suitable key, and a linger 27 stands centrally within the recess 26 and over which the socket of the key may be en* gaged so that the key may swing on the finger 27 as a pivot. The face 13 of the casing is provided with a key-hole opening 29 thro-ugh which the key may be projected or introduced, the key-hole opening 29 registering with the recess 26. The long arms of the pawls are provided with notches 2S in their inner edges and at the ends of the recess 26, so that when the key is inserted into the recess, the ends thereof may engage the notches 28 in order that when the key is turned properly or counter clockwise as seen in Fig. 3, the pawls will be forced together against the tensions of the springs so as to retract them from the ring 14.

1n the use of the gyve, it being understood that the sections which are attached to the parts of the casino` have been properly applied to the members of the limb, the pawls 22 are adapted to normally stand between the ratcnet teeth 15, so as to permit of the limited movements of the members of the limb without locking them. It will be noted that as the respective sections are swung relative to each other, the ratchet teeth 15 will be carried or moved with the part 12 spective paWls at the butt ends of the long arms and bearing against the tree ends otl the long arms of the opposite pawls.
