FINGER AND HAND GUARD Application July 29, 1932, Serial No. 625,600

12 Claims.

This invention relates to guard devices for use upon the fingers and hand of an operator to guard the fingers and the hand against injury when working on machinery of various kinds and classes, such for example as on sewing machines, cloth cutting machines, jig-saws, planers andthe like and the object of the invention is to provide a guard device made up of a plurality of finger units including two or more jointed sections disposed in alinement with the joints of the fingers to permit the free eXure of the guard in the operation of bending the fingers, thus permitting free use of the hand in handling work pieces of various kinds and classes; a further object being l5 to provide means for supporting one or more of the finger guards upon the finger or fingers of the hand, and preferably a means having elastic or resilient properties to tensionally support the guard or guards upon the fingers of the hand and yet permit the free flexure of the fingers as well as the hand at the wrist, without inconvenience to the operator or user; a still further object being to provide means for shielding or guarding the web of the hand between the thumb '25 and index finger; a further objectbeing to provide a guard wherein one or more of the sections is provided with a lining of cushioning material; a still further object being to provide a guard of the class described wherein the guard finger sections are arranged to cover the top and sides of the fingers to leave the lower surfaces of the fingers and hand exposed for engagement with the workpiece in the use of the device; and with these yand other objects in View, the invention consists in a device of the class and for the purpose specined, which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the follow 40 ing specication, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:-

Fig. 1 is a perspective view of a hand showing a complete series of finger and hand guards mounted thereon and indicating the method of their use.

Fig. 2 is a longitudinal sectional view through one of the guards shown in Fig. 1 with the parts in closed position.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 4 is a side view of the thumb guard which I employ.

Fig. 5 is a partial section on the line 5-5 of Fig. 1; and,

Fig. 6 is a plan view of a guard similar to that shown in Fig. 1 and illustrating a modified 'f method of attaching the same to the hand or wrist of the wearer.

It has iong been experienced that many casualties have occurred to workers on machinery and apparatus of various kinds and classes, and

particularly injury to the hand or fingers of the hand of operators working on sewing machines, fabric and other cutting machines, jig-saws, planers and like apparatus in the process of feeding a workpiece or workpieces into the machine. The purpose of my invention is to provide a shield or guard mounted upon the fingers so as to protect them from injury by coming in contact with the needle of a sewing machine, or

the working tool or other means of the class able for tting the five fingers of the hand, and

consisting of a thumb unit 11 and four finger units 12, 13, 14 and 15. The units of the fingers l2 to 15 inclusive differ from the thumb unit 11 in that the former have two joints and the latter has a single joint.

The brief description of one of the finger units 12 to` 15 inciusive will apply to all. These units are made up in three parts, an outer tip part 16, an inner finger and hand part 17, and an intermediate part 18. The part 16 terminates at its end in an inturned flange 19 which engages the naii of the finger to prevent displacement of the guard, each part 16, 17 and 18 being semi-circular, U-shaped or channel-shaped in cross sectional form, with the channel opening downwardly to expose the lower surfaces of the fingers from the bottom of the guards.

The inner end 16a of the outer part 16 overlaps a depressed forward part 18a of the part 18, and

the side portions of said parts are pivoted or jointed together as indicated at 20. The joined end of the part 18 ts in an outwardly pressed portion 16h of the part 16 to provide flush inner surfaces at the joints or pivots of said parts. The inner end portion 18h of the part 18 overlaps a depressed forward part 17a of the part 17,

and the parts 17 and 18 are pivoted or jointed together as seen at 21, the same as the joint 20. 'I'he part 18 is pressed outwardly at the joint as seen at 18e to provide the ush inner surface. This construction is desirable for the reason that the knuckle of the average iinger is somewhat enlarged, and it is desirable to provide a flush inner surface to prevent irritation of the joints, it being understood that the linger sections are fashioned to lit snugly around the upper end and sides of the fingers.

The inner part 17 of the iinger section has its side walls cut away as seen at 22, note Fig. 2 of the drawing, so as to conform with the crevices between the fingers of the hand. Attached to the inner end of the part 17 as seen in Figs. 1 to 4 inclusive, is an elastic or resilient strap or band 23 having at its end a loop 24 adapted to detachably engage one of a number of hooks 25 supported on the outer surface of a wrist encircling strap 26, which is secured about the wrist of the wearer by a buckle or any other means as will be apparent.

In some instances, it may be desirable to line the parts of the finger guard with a facing of suitable cushioning material. In Figs. 2 and 3 of the drawing, I have shown the part 17 with such a lining 27. It will be understood, however, that this lining may or may not be employed.

The inturned iiange 19 of the outer part or tip 16 of the iinger guard section extends to the side walls of said part as indicated at 19a, note Fig. 3 of the drawing, so as to partially cover the outer tip end of the finger and to insure against any exposure of the tip of the finger as well as to aid in holding the device upon the iinger.

The thumb section 11 differs from the linger sections 12 to 15 inclusive, in that an outer tip part 28 and an inner part 29 only are employed. The tip paitl28 is similar to the tip parts 16, the inner ends 28a overlapping depressed outer ends 29a of the part 29, and their side walls are pivoted or jointed together as seen at 30. The part 29 is of the general contour of the part 17, except that the part 29 includes a downwardly extending curved portion 31 which prevents lateral movement of the thumb section on the thumb of the hand in the operation of spreading the thumb and index ngers, especially when a web guard 32 is employed. An elastic strap or band 23a extends from the part 29 of the thumb section and is coupled with one of the hooks 25, the same as the bands 23.

The web guard 32 is in the form of a triangular or heart shaped shield, having winged portions 32o: overlapping the part 29 of the thumb sec-4 tion and the part 17 of the nger section 12-as clearly seen in Figs. 1 and 5. This guard is supported upon an elastic or yielding strap 33, the ends of which are coupled with the parts 17 and 29, the guard 32 having a loop 34 mounted on the strap 33, permitting free longitudinal movement of the guard with respect to said strap as well as permitting relative movement of the parts 17 and 29 oi the linger sections with respect to each other.

In Fig. 6 of the drawing, I have shown a slight modication wherein the iinger sections 11, 12, 13, 14 and 15 are coupled with a band 35 which covers the top of the hand `and includes at its inner end a wrist encircling strap 36 for supporting the band 35 upon the hand and Wrist of the wearer and for holding the finger sections upon the lingers of the hand, the band including an elastic insert 35a to provide a. yielding movement of the finger sections with respect to the wrist, permitting free bending of the fingers of the hand and opening and closing of the 11st.

It Will be apparent upon a consideration of Fig. 1 oi" the drawing that in flexing or bending the fingers of the hand with the guard sections mounted thereon, the depressed inner parts 180., 17a and 29a will cover and guard the joints of the iingers as the parts 16, 18 and 28 are flexed or moved on their respective pivots or joints, thus aiiording a guard and protector for the lingers of the hand, regardless of the position of the fingers or joints of the fingers.

By virtue of the curved contour of the separate parts of the guard sections, which as will be understood will be made oi a strong and durable metal, a tool such as a needle, knife or the like, will be deected from the finger, by the guard, thus avoiding injury. In cases where the fingers may be subjected to squeezing pressure, the guard will take up the major portion of the blow or pressure and vmaterially reduce the injury to the ngers.

It will also be understood that in many instances only one or two of the guard sections need be employed. For example, in needle work or for operators of sewing machines, in most cases a guard for the thumb and index finger only will be necessary and the linger guard sections 13, 14 and 15 may be eliminated. In other cases, the finger guard sections 12, 13 and 14 only need be employed.

It will also be understood that while I have shown certain vdetails of construction for carrying my invention into eect, and have illustrated different methods of supporting the guard secltions upon the fingers and hand, my invention is not limited in these respects, and various other changes in and modications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
