VIOLIN BOW.

Application filed January 6, 1923. Serial No. 611,079.

T0 all whom t may camcom.

Be it known that I, JOHN STADNICZEK, a citizen. of the United States of America, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Violin Bows, of which the following is a specification.

Thisin'vention relates to certain new and useful improvements in bows for stringed instruments such as violins and cellos and has particular reference to the4 mounting of the ends of the group of horse hairs in the frog and tip of the bow stick.

The primary object of the invention is to provide an improved means for anchoring the ends of the horsehairs of a violin bow in the frog and tip of the bow stick, the hairs being knotted at each end with the knots received in sockets formed in. the frog and tip with means for effectively retaining the knotted ends in the socket without injuring the individual hairs.

With the above and other objects in view as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a fragmentary side elevational view of a violin bow constructed in accordance with the present invention, the tip of the bow stick being partly shown in section to illustrate the anchoring of the adjacent knotted end of the horse hairs.

Figure 2 is a fragmentary bottom plan view of the bow,

Figure 3 is a fragmentary side elevational view of the handle end of the bow stick with the frog partially shown in section,

Figure 4 is a rear end elevational view of the bow,

Figure 5 is a perspective view of the sliding guard plate for the frog,

Figure 6 is a perspective view of the ferrules associated with the forward end of the frog,

Figure 7 is a perspective view of the wedge piece for the bow stick tip, and

Figure 8 is a fragmentary sectional view of the frog.

Referring more in detail to the accompanying drawing, there is illustrated a violin bow embodying a bow stick 1 having a tip 2 at the outer end thereof and a frog 3 at its inner end that is adjustably mounted upon the handle end of the stick by the usual screw 4, horse hairs 5, grouped as shown in Fig. 2 extending between the tip and frog.

The tip 2 has an end opening substantially V-shaped socket 6 formed therein for the reception of the outer knotted end 7 of the horse hairs, a wedge piece as shown in Figs. 1 and 7 embodying inclined side walls 8 and a connecting upper wall 9 with alined apertures 10 formed in the side walls, a cross pin 11 extending transversely of the tip passing through the openings 10 for anchoring the wedge piece in the socket G with the knotted end 7 of the horse hairs securely retained in the socket.

The frog 3, as shown more clearly in Fig. 3 embodies a block 12 carrying a forward eX- tension 13 while the lower face of the block is provided with a pair of spaced sockets 14. A face plate is secured to the lower edge of the block 12 and is provided with spaced openings 14a that register with the socket 14, the opposite side edges of the face plate 15 being bent to provide longitudinally extending flanges 16 as clearly shown in Fig. 2. A forward extension 17 is carried by the face plate 15 and overlies the block extension 13, the outer ends of the plate extension 17 being angularly bent as at 18 to provide a shoulder at the forward end thereof, the rear end of the plate 15 being angularly bent as at 19 and suitably secured to the rear edge of thc block 12.

A ferrule encloses the lock and face plate extension, the ferrule embodying a curved bottom wall 20 and a flat wall Q1 that is provided with a V-shaped opening 22 defining a forward rod i3. the curved bottom wall 2() of the ferrule engaging the curved bottom wall of the yblock extension 13 while the flat wall 21 of the ferrule overlies the plate extension 17. The inner ends of the group of horse hairs 5 are knotted as at 24, the knots 24 being inserted through the V-shaped opening 22 and into either of the sockets 14. A rectangular clamping plate 25 carrying a gripping piece 26 is slidably mounted in the guide anges 16 of the face plate, the forward end 25Et of the clamping plate overlying the horse hairs 5 and received in the ferrule with the forward terminal edge thereof gripping the hairs 5 at their point of overlying engagement with the cross rods 23 of the ferrule, the clamping plate 25 being retained in `its operative position by the pivotallv mounted latch 2T carried by the rear end of the block l2 as clearly shown in Figs. 3 and et.

From the above detail description of the device, it is believed the construction and operation thereof will at once be apparent, it being noted that the outer knotted end 7 of the horse hair is securely retained in the tip Q by the wedge piece shown in Fig. 7 and the cross pin 'll associated therewith, while the inner knotted end 24@ of the horse hairs niay be positioned in either of the sockets il. The clamping plates Q5 having the forward ends thereof engaging the horse hairs at their point of contact with the cross rod 23 of the ferrul'e maintains ,the horse hairs in an evenly spread position, the clamping plate 25 being retained in a locked position on the frog bv the latch 27. The desired tension on the horse hairs is accomplished by the manipulatingT screw L in the usual manner.

1While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without `departing from the spirit and scope of the invention as claimed.

What is claimed as new is l. n a bow of the type described, a bow stick, a frog and tip carried thereby, horse hairs knotted at the opposite ends received in the frog and tip, said frog including a block having spaced sockets in the lower edge thereof for the selective reception of the knot. a face plate secured to the edge lof the block and having apertures registering with the sockets, a ferrule mounted on the forward edge of the block anda clamping plate slidably mounted on the face plate and engaging the horse hairs at their point of contact with the ferrule.

In a bow of the type described, a bow stick, a frog and tip carried thereby, horse hairs knotted at the opposite ends received in the frog and lip, said frog including a block having spaced sockets in the lower edge thereof for the selective reception of the knot, a face plate secured to the edge of the block and having apertures registering with the sockets, a ferrule mounted on the forward vedge of the block, a clamping plate slidablv mounted on the face plate and engaging the horse hairs at their point of contact with the ferrule, and a latch carried by the block for securing the clamping plate in position.

3 In a bow of the type described, a bow stick, a frogand tip carried thereby, horse hairs knotted at the opposite ends received in the frog and tip, said frog including a block having spaced sockets in the lower edge thereof for the selec-tive reception of the knot, a face plate secured to the edge of the block and having apertures registering with the sockets, guide flanges at the side edges of the face plate, an outwardly directed shoulder at the forward edge of the face plate, a ferrule inclosing the forward edge ofthe block and having an openn-gin the upper side thereof defining a cross rod, and a clamping plate mounted on the face plate beneath the guide flanges overlying the horse hairs and extending into the fel-rule for gripping the horse hairs between the forward edge thereof and said ferrule cross rod.

L In a bow of the type described, a bow stick, a frog and tip carried thereby, horse hairs knoted at the opposite ends received in the frog and tip, said frog including a block having spaced sockets in the lower edge thereof for the selective reception of the knot, a face plate secured to the edge of the block and having apertures registering with the sockets, guide flanges at the side edges of the face plate, an outwardly directed shoulder at the forward edge of the face plate` a ferrule inclosing the forward edge of the bloc-k and having an opening in the upper side thereof defining a cross rod, a clamping plate mounted on the face plate beneath the guide flanges overlying the horse hairs and extending into the fermle for gripping the horse hairs between the forwart edge. thereof and said ferrule cross rod. anda lat ch carried by the rear edge of the block engaging the rear end of the clain'y'iing plate for holding the saine in operative position.

In testimony whereof l aflx my signature.
