To all whom, it may concern: in the neck 8, which become filled with the Be it known that 1, WILLIAM M. HAND, of solder.

The plate 9 is of such size 55 the following is a full, clear, and exact deas to fit snugly in its socket 3 of the head 1, scription, reference being had to the accomand the projection 11 is of such width as to panying drawings, forming part of this specisnugly fit between the bottom and top walls fication. of the socket.

The
My improved construction of holder prostem is provided with a button 14 on its outer vides, further, for a free and unobstructed end. The head 1 is provided with aset-screw flow of the electric current through the holder, 15 over each socket 3, the set-screws passing whereby resistance and consequent heating through the top of the head, as shown in Fig. II. 20 of the holder and brushes is avoided. When the brushes are inserted, the set- My invention consists in features of novelty screws 15 are tightened down, the lower ends hereinafter fully described, and pointed out of the set-screws jamming against the upper in the claims. faces of the projections 11. The plates 9 are Figure I is a top or plan View of my imthus clamped in the head by means of the 2 5 proved holder.

The head then tightens the set-screws again. If he has one ormore sockets 3,in which the brushes finds that the carbons are not held against fit. I have shown the head provided with two the commutator with sufficientpressure, he of these sockets, each adapted to contain a loosens the set-screws and forces the plates 9 brush. 4: represents part of the commutator farther into the head 1 and again tightens 0 of a dynamo, against which the carbons 5 of the set-screws.

The connection sion or pressure against the commutator and may be made by forming a socket 7 in the when necessary can be quickly and effectblock to receive a shank 8 on the carbon, as ively adjusted by the set-screws bearing on 5 shown in Figs. II and III. The shanks 8 are the long projections 11, as explained.
held in the sockets by solder 8, which not Inasmuch as the plates 9 and projections 11 only forms a secure attachment of the carfitsnuglyin the sockets of the head 1 and are home to the block but produces an excellent clamped in close bearing with the head by the electric contact between the two, and to still set-screws and inasmuch as the serpentine 50 further improve this union I form holes 8 ribbon-springs form an electric connection between the block 6 and the head 1 through the plates 9 and projections 11 of large current-conducting capacity there is no danger of the heating of the parts and the consequent loss of current and carbon.
I claim as my invention-- 1. In combination with a eommutator-brush and a holder thereforhaving a socket; a spring for pressing the brush and conducting the current, working in said socket and formed of flat metal having its transverse dimension in the direction of yielding reduced to give the requisite resiliency and having its other transverse dimension relatively increased to afford ample section for conductivity without heating, as herein explained.
2. In combination with a commutator-brush holder having a socket; a spring working in said socket for pressing the brush and conducting the electric current, formed of metal having its transverse dimension in the direction of yielding reduced to give the requisite resiliency and having its other dimension increased to afford ample section for conductivity without heating, said spring being formed by bending the metal backward and n seasar forward upon itself in serpentine form, sul stantially as herein explained.
3. In a brush-holder, the combination of a head having a socket, a block fitting in the socket and adapted to carry a carbon, a plate fitting in the socket and having an inwardly extending projection and an outwardly-ex tending handle, a set-screw fittin in the head and adapted to bear against said projection, springs connecting said block to said plate, and a stem connected to said block and passing loosely through said projection and said handle, substantially as and for the purpose set forth.
4. In a brush-holder, the combination of a block having a socket, and a carbon having a neck fitting in the socket and held therein by solder, substantially as set forth.
5. In a brush-holder, the combination of a block having a socket, and a brush having a perforated neck it-ting in said socket and held therein by solder, substantially as set forth.
