foi tension of the thread. 7. The facility with which this machine 

 can be made b}^ the system of duplication. 



We therefore strongly commend it to honors of the first class. 



The article bearing the number 983, (Empire Sewing Machine 

 Co.,) is a simple and desirable machine. The cam motion for ope- 

 rating the needle is ingenious, and the operation of the needle 

 thx'ough this and the connection of the peculiar , " take up " on the 

 thread, commend it to second class honors. 



The article bearing the number 817 (Stackpole Manufacturing 

 Co.) is decided to be a highly ingenious and meritorious machine. 

 It presents the novelty of a duplex attachment, which allows two 

 rows of stitches to be formed at the same time. This duplex 

 attachment is worked by the same mechanism as that which drives 

 the single needle, and it is easily detached and put on. The varior 

 hie feed motion allows work on circular seams, or stitching to be 

 worked on any radius, by simply afrauging the relations of the 

 feed bars one to the other. The tripping of the needle for the 

 purpose of threading is a good feature. We commend the above 

 machine to honors of the second class. 



The article bearing the number 809 (J. W. Bartlett) is decided 

 to be a good simple machine, and of a class that is desirable on 

 account of its cheapness and simplicity. ^ Its principal noticeable 

 feature, otherwise, is that it can be run in both directions without 

 injury. We commend it to third class honors. 



The article bearing the numlier 606 (Halligan & Shapter) is for 

 sewing leather, with waxed or unwaxed thread, and is the only one 

 of its class on exhibition. It is a highly ingenious machine, and its 

 several motions are admirably adai)ted for the kind of work it per- 

 forms. The excellence of the machine and the importance of the 

 branch of manufacture for which it is intended, cause us to com- 

 mend it for first class honoi-s. 



The article bearing the number 799 (Miss Jane Gray) is recom- 

 mended to notice by a very ingenious feed font, and the equally 

 ingenious attachments for embroidering in great variety, and fring- 

 ing. The novel features for the above purposes will commend it 

 to second class honors. 



Kolling Platforms for Sewing Machines, number 973 (Sibley & 

 Stoops). Its merits are simplicity of construction, firmness of the 

 platform on the floor when the roll is locked, and freedom of 

 motion when it is unlocked, for moving the machine. Third class 

 honors.
