MOSES MARSHALL, OF LOWELL, ASSIGNOE TO S. S. BUOKLIN, OF BROOKLINE, MASSACHUSETTS.

IMPROVED MACHINE FOR PEGGNG BOOTS AND SHOES.

Specification forming part of Letters Patent No. 37,136, dated December 9, 1862.

.To all whom it may concern:

Be it known that I, MosEs MARSHALL, of Lowell, in the county ot' Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Pegging Boots and Shoes, ot'which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which Figure l is a vertical section through a pegging-machine for which Letters Patent were granted to me on the 25th of March, 1862, and 011 which my presentinvention is an improvement; Fig. 2, a similar section through my improved machine.

It is evident that the shorter the machine is made the less it will be disturbed by the blow ot' the hammer, and the less liable it will be to be thrown to one sideor the other, and the longer the machine the greater the care required to hold it perpendicular lietore it is struck and to deliver the blow steadily and fairly upon the plunger-head. It is therefore desirable that the machine be made as short as possible, and at the saine time allow the necessary size and play to the operating parts. On the other hand, it is evident that the longer the spring by which the piston is raised, and the greaternumber of turns which it contains, the less it will be affected by a certain amount of compression, either as regards a liability to set or to break. It becomes, therefore, desirable while the machine is shortened that the spring be lengthened, desiderata which in the old machine were incompatible with each other.

The awl in machines of this description is liable to breakage, and in order to take ont the plunger for the purpose of inserting a new one in the machines as heretofore constructed itis necessary to take the machine apart. This occasions delay and loss oi' time, which it is de sirable to economize.

To enable me to accomplish all these ends that is, to shorten the machine and at the same time to lengthen the spring and make it of an additional number oi' turns, and also to so construct the peg-ger that the plunger may be removed for the purpose ot inserting an awl without disturbing the other parts otl the machine-is the object of my invention, which consists in surrounding the piston by a cylinder or sleeve, against which the Lipper end of the spring abuts, whereby an increase of space for the accommodation ot' the sprin g is obtained, and the piston, no longer connected directly to the spring may at any time be withdrawn by removing the screw by which itis connected with the sleeve, while the body ofthe machine, no longer being required to accommodate the entire length of the spring', may at the same time be shortened.

To enable others skilled in the art to understand my invention, I will proceed to describe the manner in which I have carried it out.

In Fig. l is represented the machine for` which Letters Patent of the United States were granted to me on the 25th ot` March,

1862. In this machine the plunger B is raised by the spring O, the upper end of which bears on a ring, D, that rests against the pin E, projecting from the plunger.

In the machine represented in Fig. 2, which i is my improved machine, a hollow cylinder or sleeve, G, is attached to the plunger B by a screw at a., there being a 'space between the plunger and the sleeve for the accommodation of the elevating-spring O, the upper end ot' which abuts against the projection of the sleeve. The sleeve is held in its place in thc machine by the cap H, which is secured to the body of the machine by screws c, and projects over the ledge o upon the sleeve.

By means of theabove construction a much greater space is obtained t'or the accommodation ofthe spring, and the latter may consequently be lengthened or the body ot' the machine shortened.

In the machine represented in the accompanying drawings the number ot' turns of the spring have been increased, and the machine at the same time has been considerably shortened.

To remove the plunger B ior the purpose of replacing the awl, it is simply necessary to
