STEPHEN PALMER, OF LANSINGBURG, NEW YORK.

S'ASH-CORD GUIDE.

SPECIFICATION forming part of Letters Patent No. 370,647, dated September 27, 1887.

Application filed April 28, 1886.

To all whom it may concern:

Be it known that I, STEPHEN PALMER, a resident of Lansingburg, in the county of Bensselaer and State ofeNew York, have invented certain new and useful Improvements in Oombined Sash-Cord Guide and Mortise-Marker; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in combined sash-cord guide and mortise-marker; and it consists of a sash-cord guide having the face-edges of the pulley-case curved to form a series of arcs of circles and provided with marking-spurs integral therewith and located centrally of the several arcs along one or both of the face-edges.

The objects of my invention are fully set forth in connection with the following description.

Figure 1 of the drawings is a face view of my improved device; Fig. 2- is a side view of same. Fig; 3 is a plan view of a portion of a 'window-jamb marked for boring to form a mortise.

I am able to make use of any form of pulley case or shell having its face-edges curved to form a series of arcs of circles adapted to fit a corresponding series of auger-holes forming the mortise adapted to receive the case.

I have shown a plain well-known case, D, provided with face-edges curved to form the arcs of circles O 0 along each edge of the case on opposite sides of the sheave or pulley P,

which pulley is interiorly mounted upon an axle supported by the case. Centrally of each are is a little spur, a, projecting from the faceedge along one or both sides of the case.

Instead of spurs notches a out in the edges, may be employed, as shown on one side;

The advantages of the curved face-edges adapted to fit a series of auger'holes are well known to builders.

To make the required mortise it is only nec- Serial No. 200,421. (No model.)

essary to bore holes in the jamb or other object of a size to correspond with the arcs O, the twoend holes being of snfficient depth to let the plate in flush with the surface of the jamb and the intermediate holes of a depth to admit the pulley and case D, no chiseling be ing required. If the holes are bored at the proper distances from each other, the faceedges will accurately fit and present a very neat and finished appearance; conversely,if

the holes are not properlylocated, the edges.

will not fit. To successively and accurately measure the distance for each hole as it is bored would require much time and care and render the operation as laborious as the old method of using the chisel.

By means of the spurs a along one face-edge I am able to mark the center of each hole by a single blow upon the opposite edge, and it is only necessary to successively insert the screws of the bit or anger in the marks so made when the holes are bored to insurethe proper position of the holes relatively to each other. The device is so placed that the spurs on one face-edge rest upon the window-jamb, and a slight blow given upon the opposite edge produces small'indentations or marks I) in the jamb; or by drawing the device across the jamb the latter will be scratched bythe spurs, and by inserting the screw of the bit in these marks or scratch lines holes indicated by dotted lines can be formed which the face-edges of theplate or case will exactly fit.

The number of arcs employed may be varied as desired. I have shown five, the two end ones havingscrew-holes and forming parts of a face-plate by which the device is secured in place. By combining the guide and marker in one implement I am able without additional expense to provide each sash-cord guide with a marker which is always at hand ready for use, thereby avoiding the expense of providing separate implements for the purpose and the inconvenience of keeping such implements within reach when preparing mortises for sash-cord guides.

WhatI claim as new, and desire to secure by Letters Patent, is=
